How to Better Find the Fault of Buried Cables in Rural Areas
How to Better Find the Fault of Buried Cables in Rural Areas
In the transformation of China's agricultural network, buried lines have been adopted in many areas. Although PVC insulated plastic wire has many advantages, such as good chemical stability, no occupation of farmland, safe operation and reduction of line loss, after long-term use, due to various reasons, the fault phenomenon of buried wire is gradually increasing. Let's take a look at how to carry out the fault finding of buried cables in rural areas. Methods and characteristics of fault finding and detection of buried cables in rural areas. 1. Analysis and judgment method for the fault of buried line, generally, we should first understand the relevant situation of the fault, then conduct comprehensive analysis, find out the cause of the fault, and then find and eliminate it pertinently. For example, finding informed parties, such as construction workers, wire users, and other relevant personnel to understand the situation in detail, can often eliminate the fault in the shortest time and at less cost. It has the advantages of simple operation, no need for complex instruments, and can eliminate some faults in time. This method is generally not used alone, but in combination with other instrument detection methods. 2. In recent years, the intelligent cable fault tester is widely used to detect the fault buried wire. Therefore, many electricians and maintenance personnel are not familiar with the fault finding and detection methods of rural buried cables. In case of underground pipeline failure, if there is no advanced detection equipment and good detection means, the failure can often not be eliminated within the service period promised by the power supply enterprise, which not only delays time and wastes manpower, but also affects the image of power users and frustrates the enthusiasm of farmers to transform the rural power network. Therefore, rural land buried lines need more specialization. More efficient fault detection equipment. 3. Compared with buried wires, buried power cables have been used in China for decades. The buried cable fault tester has developed from resistance bridge, capacitance bridge and standing wave test to flashover test. The development of the instrument has experienced the ordinary oscilloscope tube display flash lamp and the storage oscilloscope tube display flash lamp. At present, the intelligent instrument has been developed. The instrument adopts new technologies and processes such as large-scale integrated circuit, computer processing technology and large screen LCD. The power cable tester is used to transform it and detect the buried line fault. The effect is good and the efficiency is high. After a lot of practice, the detection of a buried line fault generally does not exceed 30 minutes from the beginning to the end, and the accuracy is very high.
What Are the Methods of Cable Fault Detection
What Are the Methods of Cable Fault Detection
The fault types of power cable mainly include parallel fault and series fault. Series fault refers to the disconnection of multiple or one conductor in the cable. Usually, it is difficult to detect the series fault before disconnecting a conductor in series. It is easy to find the series fault only when there is a real short circuit. Parallel fault is caused by external insulation aging caused by cable overload operation for a long time, and then partial discharge, resulting in parallel fault. The cable fault different from the length difference and resistance value is broken down, and the cable fault can be divided into high resistance type, low resistance type and open circuit fault. So what are the methods of cable fault detection? Bridge method: bridge method is a traditional method of cable fault detection, which can achieve very ideal results. This method is convenient and fast with high detection accuracy. It belongs to a common cable fault detection method. However, due to the low bridge voltage difference and galvanometer sensitivity, it is only suitable for fault detection with small cable resistance. Moreover, it is difficult to detect the open circuit fault of equipment and cable with high resistance. High voltage bridge method: high voltage bridge method is a common fault detection method in cable fault detection. Its detection principle is that in the high-voltage bridge, when the constant current power supply pierces the cable, it will ensure a large bridge current to a certain extent, so as to form a certain potential difference on both sides of the overall bridge, so as to count the fault points on the basis of coordinating the bridge. This method is suitable for high voltage constant current power supply, and can effectively expand the detection range of high resistance of bridge. Relatively speaking, the result is more convenient and accurate. In addition, for the research theory of bridge method, the characteristics of cable centerline resistance and proportional distribution of the whole line can promote the formation of bridge detection system. Impulse high voltage flashover method: impulse high voltage flashover method is widely used in some methods of cable fault detection. The detection principle of this method is to apply impulse high voltage at the beginning of the faulty cable, so that it can quickly puncture the place where the fault occurs, and record the data information of voltage sudden change at the moment of the fault place. Through the analysis of wired fault point and wired initial data information, the time distance is tested, so as to obtain the fault location and uncertain countermeasures. Low voltage pulse reflection method: when low voltage pulse emission method is used to detect cable fault, low voltage pulse shall be injected into the damaged line. When the pulse is transmitted along the cable to the fault point, when the inappropriate impedance is encountered in the process of transmitting current, the reflected pulse is displayed on the detection device and reflected through the data record of the device, and then the round-trip time difference of the output pulse and the cable wave speed are calculated, so as to obtain the distance between the fault point and the test point. This method is very simple and can make the test results particularly significant. When it is difficult to determine the fault data, it can be detected directly. However, it also has disadvantages, that is, it is not suitable for high resistance fault and flashover fault. Secondary pulse method: for the secondary pulse method, it is effectively applied to form the impulse high-voltage pulse at the moment of the integrated high-voltage generator and introduce it to the cable fault location. On the premise of effectively piercing the fault location, it can prolong the uninterrupted time of arc formation at the fault location after breakdown. Obviously, it must be clear that at the same time, a trigger pulse can trigger the automatic trigger device of the secondary pulse and the operation of the cable detection instrument. On the basis of starting the automatic trigger device of the secondary pulse, two low-voltage pulses are transmitted. Through the device of forming the secondary pulse, the cable is effectively transmitted on the fault detection cable, so as to break down the cable. Using the cable fault detector, observe the floating characteristics of voltage waveform and the reflection wavelength in the whole process of forming arc, comprehensively and systematically record the screen of detection equipment, and distinguish various current fluctuations, one of which reflects the actual length of cable and the other reflects the actual distance of short-circuit fault.
Operation Precautions of Mine Cable Fault Tester
Operation Precautions of Mine Cable Fault Tester
Coal mines and oil wells are large users of cables. Due to the harsh underground operating environment, the annual damage of various cables is relatively large. In order to save expenses and reduce production costs, each mine and oil well is generally equipped with its own cable maintenance department. However, due to the limitation of testing equipment, the maintenance of cables is often unsatisfactory; The AC / DC cable detection device independently developed and produced takes the high-voltage breakdown method as the principle, so that users can accurately find the cable damage point in the maintenance process. Moreover, the mining cable fault tester also has the function of testing after the old cable is repaired. Therefore, this device is an essential maintenance equipment for cable maintenance companies in coal mines and oil wells. 1. Insulating rubber pad shall be added before the equipment. 2. Operators shall wear insulating rubber shoes and insulating gloves. 3. The tested cable core and high-voltage terminal shall be firmly fixed with nuts to maintain good contact and avoid leakage and current increase caused by * * discharge. 4. Irrelevant personnel shall be prohibited from approaching the work site. 5. After one year of use, the transformer oil shall be subject to withstand voltage inspection in time, and the withstand voltage shall not be less than 30KV / 2.5in. 6. Regularly (depending on the strength of the equipment), carefully polish the surface of the discharge copper ball with zero sandpaper, and keep the surface and surrounding clean and free of dust. 7. The use effect of the equipment depends on the careful maintenance of the user, the continuous accumulation of operation experience, and the mastery of the relationship between the ball gap spacing and the discharge voltage of different cables.

Operating Steps of Live Cable Identifier
Operating Steps of Live Cable Identifier
1. Connect the transmitting source: the live cable identifier inserts the red and black wiring plugs of the transmitting caliper a into the two red and black wiring posts corresponding to the transmitting source, and clamps the transmitting caliper a on the identified cable. The arrow on the transmitting caliper a points to the cable terminal. Both ends of the identified cable shall be reliably grounded. For cables that do not operate, the core wires at both ends can also be grounded. 2. Turn on the power switches of the transmitting source and receiver to check the direction: on the identified cable two meters away from the transmitting caliper, clamp the receiving caliper B to the cable, and the arrow on the caliper must point to the cable terminal. Then check the current direction and test connection direction. At this time, the pointer of the receiver ammeter must deflect to the right, and there is an audible and visual prompt at the same time. If the arrow of the receiving caliper B points to the transmitting source end, there will be no audible and visual prompt, and the pointer of the current meter will deflect to the left. Remember the deflection direction of the receiving caliper gauge. 3. Identification: at the identification point, use the receiving caliper B to identify each cable. During identification, the arrow on the receiving caliper must always point to the terminal direction of the cable, and the cable shall be clamped one by one. On the identified cable, the current meter pointer of the receiver must be deflected to the right, and the audible and visual alarm prompt shall be given at the same time. On other cables, the pointer of the receiver current meter must deflect to the left without audible and visual alarm. The pointer of the current meter of the receiver deflects to the right, and the audible and visual alarm prompt is the cable to be searched and identified. This test result is unique. That is, no matter how many cables there are in the cable trench, when each cable is identified with the receiving caliper B, only the receiver current meter pointer on one cable (the cable to be found and identified) deflects to the right and gives an audible and visual alarm. Dear customers: Hello, our company is a high-quality development group with strong technical force, providing users with high-quality products, complete solutions and superior technical services. The main products are underground cable fault tester, cable fault tester, cable fault tester, etc. The enterprise adheres to the tenet of building a business in good faith, keeping the business with quality and developing the business with enterprising.

The Optical Fiber Connector
The Optical Fiber Connector
A fiber optic connector is a detachable (active) connection between an optical fiber and an optical fiber. The two end faces of the optical fiber are precisely butted together so that the optical energy output from the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. It also minimizes the impact on the system due to its involvement in the optical link, which is a basic requirement for fiber optic connectors. To some extent, fiber optic connectors affect the reliability and performance of optical transmission systems.Basic introductionA connecting device for re-plugging between optical fibers, also called a fiber optic movable joint. The main performance parameters (and typical values) are: insertion loss ( 5dB), plug-and-repeat repeatability and interchangeability between connectors (500 changes). When used in a large-capacity high-speed transmission system, reflection is also required to be small.IntroductionOptical fiber connectors can be divided into single-mode and multi-mode connectors of common silicon-based fibers according to different transmission media, and other fiber-optic connectors such as plastics; the structure of the connector can be divided into: FC , SC, ST, LC, D4, DIN, MU, MT, etc. Among them, ST connectors are usually used for wiring equipment terminals, such as fiber distribution frames, fiber modules, etc.; and SC and MT connectors are usually used for network equipment terminals. According to the shape of the end face of the fiber, there are FC, PC (including SPC or UPC) and APC; according to the number of cores of the fiber, there are also single core and multi-core (such as MT-RJ). Fiber optic connectors are used in a wide variety of applications. In the actual application process, we generally distinguish according to the structure of the fiber optic connector. Here are some common fiber connectors:FC type fiber optic connector This connector was first developed by NTT Japan. FC is an abbreviation of Ferrule Connector, which indicates that the external reinforcement method is a metal sleeve and the fastening method is a turnbuckle. At the earliest, FC type connectors, the mating end faces of the ceramic pins used were planar contact (FC). The connector has the advantages of simple structure, convenient operation and easy manufacture, but the fiber end face is sensitive to fine dust, and Fresnel reflection is easy to occur, and it is difficult to improve the return loss performance. Later, this type of connector was improved by using a pin (PC) with a spherical end face, and the external structure was not changed, so that the insertion loss and return loss performance were greatly improved.SC type fiber optic connector This is a fiber optic connector developed by NTT Corporation of Japan. The outer casing has a rectangular shape, and the structure of the pin and the coupling sleeve is exactly the same as that of the FC type. The end face of the pin is mostly made of PC or APC type; the fastening method is a plug-and-pin type, which is not required. Rotate. Such connectors are inexpensive, easy to insert and remove, have small fluctuations in insertion loss, high compressive strength, and high installation density.The ST and SC interfaces are two types of fiber connectors. For 10Base-F connections, the connectors are usually ST type. For 100Base-FX, the connectors are mostly SC type. The core of the ST connector is exposed and the core of the SC connector is inside the connector. Biconic Connector The most representative of these types of fiber optic connectors was developed by Bell Laboratories of the United States. It consists of two precision-molded ends with frusto-conical cylindrical plugs and a double-conical plastic sleeve inside. The coupling assembly of the barrel.DIN47256 fiber optic connector This is a connector developed by Germany. The connector and coupling sleeve of this type of connector have the same structural dimensions as the FC type, and the end face treatment adopts PC grinding. Compared with the FC type connector, the structure is more complicated, and the internal metal structure has a spring that controls the pressure, so as to avoid damage to the end surface due to excessive insertion pressure. In addition, the mechanical accuracy of such a connector is high, and the value of the insertion loss is small. MT-RJ type connector MT-RJ started with the MT connector developed by NTT, with the same latching mechanism as the RJ-45 LAN electrical connector. The optical fiber is aligned with the guide pin mounted on both sides of the small sleeve for easy transmission and reception. The machine is connected, and the connector end face fiber is a double-core (interval 0. 75mm) arrangement design, which is the next-generation high-density optical connector mainly used for data transmission.LC connector The LC connector was developed by the famous Bell Institute and is manufactured using a convenient modular jack (RJ) latch mechanism. The size of the pins and sleeves used is half that of ordinary SC, FC, etc. , which is 1. 25 mm. This can increase the density of the fiber optic connectors in the optical distribution frame. At present, in the single-mode SFF, the LC type connector has actually occupied a dominant position, and the application in multi-mode has also grown rapidly.MU type connector The MU (Miniature Unit Coupling) connector is the worlds smallest single-core fiber optic connector developed by NTT based on the most widely used SC-type connector. The connector uses a 1. 25mm diameter bushing and self-retaining. The advantage of the organization is that it enables high-density installation. With MUs l.25mm diameter bushings, NTT has developed a series of MU connectors. They have socket type optical connectors (MU-A series) for fiber optic cable connection, backplane connectors with self-holding mechanism (MU-B series), and simplified sockets for connecting LD/PD modules and plugs (MU-SR series) )Wait. With the rapid development of fiber-optic networks to larger bandwidths and larger capacity and the widespread use of DWDM technology, the demand for MU-type connectors will also grow rapidly.MC connectorIn 2012, the domestic communication company independently developed a smaller and denser MC connector than the LC connector. The Nippon MC Fiber Optic Active Connector is a high-density single-core fiber optic connector for high-density applications such as high-capacity central rooms and high-density data centers. The MC fiber optic connector has a high density and can double the LC connector in the same space, making it the worlds smallest and densest connector.The main parameters:General structureThe main purpose of fiber optic connectors is to achieve fiber optic connections. Optical fiber connectors that have been widely used in optical fiber communication systems are numerous in variety and structure. However, the basic structure of various types of fiber optic connectors is consistent, that is, most fiber optic connectors are generally made of high-precision components (composed of two pins and one coupling tube). Alignment of the fiber.In this method, the fiber is inserted into and fixed in the pin, and the surface of the pin is polished to achieve alignment in the coupling tube. The outer components of the pins are made of metal or non-metal materials. The butt end of the pin must be ground and the other end typically uses a bend limiting member to support the fiber or fiber optic cable to relieve stress. The coupling tube is generally made of two semi-synthetic, fastened cylindrical members made of ceramic, or bronze, and is equipped with a metal or plastic flange to facilitate the mounting and fixing of the connector. In order to align the fiber as precisely as possible, the processing precision of the pin and the coupling tube is very high. PerformanceThe performance of fiber optic connectors, first of all, optical performance, in addition to the interchangeability, repeatability, tensile strength, temperature and number of insertions and removals of fiber optic connectors.(1) Optical performance: For the optical performance requirements of the optical fiber connector, the two most basic parameters of insertion loss and return loss are mainly used.Insertion loss (InsertionLoss) is the loss of the effective optical power of the link caused by the introduction of the connector. The smaller the insertion loss, the better. Generally, the requirement should be no more than 0.5dB.ReturnLoss (ReflectionLoss) refers to the ability of the connector to suppress the reflection of the link optical power, and its typical value should be no less than 25dB. In the practical application of the connector, the surface of the pin has been specially polished to make the return loss larger, generally not less than 45dB.(2) Interchangeability and repeatabilityThe fiber optic connector is a universal passive device. For the same type of fiber optic connector, it can be used in any combination and can be used repeatedly. Therefore, the additional loss introduced is generally less than 0.2 dB.(3) Tensile strengthFor a good fiber optic connector, the tensile strength is generally required to be no less than 90N.(4) TemperatureGenerally, fiber optic connectors must be able to operate at temperatures between -40oC and 70oC. (5) Number of insertions and removalsThe fiber optic connectors used can be plugged and unplugged more than 1000 times.Connection step1. The Fiber Optic Quick Connector is an innovative field termination connector that includes factory pre-installed fiber, pre-cast ceramic ferrules, and a mechanical splice mechanism.2. When the termination is completed, only the introduction fiber or the indoor fiber can be inserted into the mechanical connection mechanism, without using other tools, the termination process takes only about 2 minutes, which greatly saves the installation time. 3. The ferrule and end face of the fiber optic quick connector are pre-ground and pre-polished at the factory, and the mechanical connection mechanism is located at the end of the ferrule to fix the inserted fiber.4. The mechanical connection mechanism is mainly composed of a V-shaped groove and a clamping element; when a fiber needs to be inserted, the V-shaped groove is opened by a wedge-shaped clamp to facilitate the smooth insertion of the optical fiber.5. When the fiber is inserted into the V-groove and fixed, remove the wedge clamp from the V-groove. In order to facilitate users to better understand and select fiber optic connectors, Konnra Electronics hereby organizes the knowledge and classification of fiber optic connectors, and hopes to be helpful to the majority of users RELATED QUESTION Do I have to acquire some type of license to sell medical equipment on an e-commerce site?

[closed]Hey. I actually have the same setup at my work. I must say it does not have sense, if you use QC only to store defects. If you need bug tracking, you can stick with Jira. But you must understand that QC is tool dedicated for QA and it does much more. So it has sense to have Jira and QC if you (I mean QA at your work ) use all/most of QC features and you have Jira plugin that synchronizes defects between QC and Jira (I know about two plugins for Jira like that).[end of answer] If you are thinking 'but why the fck QA needs this stupid tool?' let me uncover a bit about QC for you. Please understand that although both provide bug tracking capabilities, they have very different target and purpose. I assume that most people (programmers) here know Jira, so I will uncover a bit about QC for you: P.S. It is a big tool, used properly works great, otherwise it sucksCan People Fool Benevolent Brother's 'Alibi Trackers' and Escape?As Angel pointed out, the system as you described is vulnerable to MitM and proxying attacks.For a secure alibi, we need the process to work like this:CT then knows these things:The following tricks are therefore avoided:Light speed is 300,000 km/sec, so 10km is 10/300,000 seconds, or about 33 microseconds. 66 for a round trip.The inaccuracy of cell triangulation is quite high: only to the nearest 1000m (about 3 light-milliseconds). So we can only calculate transmission times to the tower with an accuracy of about 3ms.Still, if a signal is delayed by 33 microseconds each way, that's 10 times the deviation we are willing to accept, and it means there's something up.With a system like this, proxying as described by Angel could work, but only within at most 1000m of where you are meant to be. You might be able to get a few more meters out of it, if instead of a single proxy, you put one on each triangulating cell tower, with a directional antenna to speak only to that tower. But it would not help much.Worse, the 1000m becomes MUCH less in areas where there are a lot of cell towers so triangulation is more accurate. And you can never tell how many towers there are, since they could be hidden. It would be in BB's interest to have lots of them.Benevolent Brother is not stupid.In the case of sophisticated tricks, no alarm would sound, no paddy-wagons get sent out. That's for people who just put on tin-foil hats and call it a day, not for sophisticated hackers. Benevolent Brother knows that everything like this is an arms race: once people know that their clever tricks do not work any more, they go to ground until they can develop cleverer and cleverer tricks. So it's important to let them think they are winning the arms race, so they do not develop better tricks.So, BB is unlikely to act overtly against someone using Angel's proxying trick, and instead will focus other surveillance methods on them until it's certain that everyone involved in producing the system has been identified, and he knows what they are planning. .. which he might even allow to continue. Since anyone who made proxying or spoofing equipment would be known, and all uses of the equipment would be of highest interest to BB, anyone getting hold of the equipment for a sophisticated trick would likely already be under very close surveillance before even using it.So, if you can not fool it, what can you do?I think the answer is obvious. They are tracking the movements of your head, your phone, your car, your public transport use, your creditcard use. They are using facial recognition on the surveillance cameras on every corner, and every cellphone and car is also a surveillance camera. They will know if you go anywhere you should not be.So if the smuggler's den is under a big farmer's market, take up an interest in fresh fruit and veg, and then you are just visiting the market. Well, it's the weekend, why not visit some museums and galleries? Why it's practically your civic duty to gaze upon those portraits and busts of Benevolent Brother every now and then.To evade the Alibi Tracker, you do not need fancy technology hacks.

Klein Tools VDV501-823 VV Scout (r) Pro 2 Tester Kit Test Voice (RJ11-12) and Data (RJ45) via Video-to-F connector or coaxial connection. Before testing, make sure you remove the cable from your computer, modem or router.A cable tester checks the electrical connection between signal and cable and confirms that everything is wired correctly at both ends of the cable. With the HOSA CBT 500 you can test your cable gigging quickly and easily.Check that the cable connection you want to test is ready for analysis and that the tester is not electrocuted or that the device breaks. Test your network cables as with a network cable tester and run the test. If you connect both ends of the cable, a network cable tester will do the job for you and get an accurate reading of whether your cable is working or not.If you need to test voltage and current continuity, you should get an electric tester. With these testers you can test the cable against volts, current and ohms to check if the circuit is short-circuited through the cable. The testers can measure both AC and DC voltage and current in seconds.Continuity tests help to verify and reverse electrical circuit connections. For example, when two wires melt in a sheathed cable, a continuity detector lights up when you touch one probe with the black wire and the other with the white wire. Continuity testers are also excellent for checking if the wires are running smoothly and to see if the circuit is complete.Continuity checks can also be used to detect problems with cold soldering between wires or wire products. In addition, this type of electrical testing can also be used to check connection pads and traces on printed circuit boards (PCBs ).The most common and basic method to perform a continuity test with the help of a resistance tester is a simple multimeter function. Specialized continuity testers are available, but the most basic is an inexpensive light bulb that lights up when electricity is flowing. A digital multimeter continuity test can be used to test switches, switches, fuses, electrical connections, conductors and other components.A continuity tester consists of a battery, a housing, a probe connected to one end of the housing and a test wire connected to the other end with an Alligator clip. A continuity test on an electrical circuit is performed when it is not switched on by using a tester. To use a continuity tester, first pull the device off the connector and disassemble it to get to the component you want to test.Continuity testers are easy to understand: they consist of a battery housed in a housing, a cover, a probe for testing the wire, a tensed end of the battery in the housing and an alligator clip for the second end.A continuous tester is an electrical tester used to determine whether an electrical path has been created between two points [1] where an electrical circuit is produced. Its user-friendliness is determined by the fact that it is a power switch to determine whether an electrical device maintains a flowing current flow in its body. If this is not the case, it is used to find out the root of the problem within the device.Testers are excellent for checking whether a device is working properly, such as a single-pole switch, or for checking lamp wiring to see that electrical paths are intact. Make sure you turn off the power for the circuit or the device you are testing. These test tools allow network technicians to isolate cabling problems and network protocols to solve problems.This works with any coaxial cable with a special tester, whether you are using a VDV512 or 007. Like James Bond, the tester will spy on the cable and help you identify and label the right cable.A continuity tester is a special electrical device used to check the continuity of cables and wires in a circuit. A network tester calculates the signal and power transmitted from one end of a connection to the other in a twisted pair. If the cable is continuous, this means that all voltages applied to the cable are in the same place.If you want to check the quality of your cables, use a standard tester. Professional network testers are used in commercial environments and are used by certified professional cable installers to get the job done.Test tools do not provide bandwidth readiness information for high-speed data communication. Certification audits are a way for installers to ensure that the cable fed into the network meets TIA and ISO requirements. These tests are performed by professional network testers and certified installers.To help you find the best network and cable tester for your use, I have compiled a list of test products that work well. The LinkIQ cable network tester is easy to use as explains Eric Webb, Flukes Network Product Manager, in the video below. It shows the settings to use and how to use them to perform cable tests, save the results and upload them to linkware where they are available.I came across the Elegiant Network Cable Tester while working on establishing a LAN connection for a local company. With my extensive experience as an electrician, I can say that this is the best tool for testing cable connections.Selecting, selecting and purchasing a suitable network cable tester can be a complicated and challenging task. In this article, a great effort has been made to show you how to test the continuity of circuits and how a good continuity tester will handle your situation. This article examines which tools are best suited for normal cables, which are best suited for coaxial cables, which are to be used and which cable types are to be considered when measuring the limit values.
