How to Quickly Detect the Fault Point of Low Voltage Cable
How to Quickly Detect the Fault Point of Low Voltage Cable
In many years of specific work, people have found that there are many differences between the common faults of high-voltage cables and low-voltage cables. Most of the faults of high-voltage cables are dominated by common faults of operation, and most of them are common faults of high resistance, which can be divided into leakage and flashover; The common faults of cable can only be led, short circuit and open circuit (naturally, high-voltage cable also includes these three conditions). In addition, the cable also has the following characteristics in the whole process of specific application: 1. The laying is blind, and the relative path is not very clear. 2. When laying, it is not buried after filling sand and bricks like high-voltage cables. On the contrary, the buried depth is shallow, which is easy to be damaged by external forces and common faults occur. 3. Cables are generally short, ranging from tens of meters to 500 meters, unlike high-voltage cables, which are usually 500 meters to many kilometers. 4. The compressive strength of the insulating layer is low. When solving common faults and making connectors, the processing technology is relatively simple. 5. Most cables are often burnt and damaged at common fault points. The common fault point is that there is no mark on the surface of the cable, which is very rare. ⒍ the required load changes greatly, and the two colors are usually unbalanced, which is very easy to get hot, resulting in common faults. Considering the above characteristics of the cable and the proposals clearly put forward by many customers and the specific application status of people in each region, the scientific research staff has successfully developed and designed the DW cable fault test mobile phone positioning system: the system software includes two parts: rangefinder and detector. The range finder of hn-213x system software is a completely intelligent system and personalized design scheme. It automatically detects the cable fault point without manual service, analyzes the common fault wave type, and immediately gives the distance between common fault points and common fault characteristics. The rechargeable battery power supply system is selected, which is convenient for field work, small in size, light in weight, easy to use, and does not need all auxiliary machinery and equipment. The cable fault detector of hn-213x system software is an instrument and equipment for simultaneous and accurate positioning and detection of the laying relative path, buried depth and common fault points of directly buried cables. Because it is a mobile phone positioning system for common cable faults based on the magnetic effect of current and the basic principle of step voltage, it mostly considers all standards of cable fault test. This kind of detection system software has many advantages compared with the cable fault detector based on the impulse flash method: 1. A variety of test standards are integrated and the results are mutually certified to clarify the uniqueness of common fault points. 2. Small size, light weight, easy operation by one person, no auxiliary machinery and equipment. 3. The rechargeable battery power supply system is selected, which is suitable for field work without ignition, charge and discharge. 4. The relative path search of cable (which can be clearly in the middle of 30cm), buried depth detection and accurate positioning of common fault points are carried out in the same step with high efficiency. 5. Clarify the common fault points, and the instruments and equipment have visual display information without wave type analysis. ⒍ it will not be harmed by underground conditions (such as bifurcation of cable, bundling, distortion of connector, etc.). Like detecting bombs, it searches common fault points point by point, and the accurate positioning deviation is within more than ten centimeters, which is very accurate. ⒎ it will not be harmed by ground conditions, such as floor tiles, road greening, concrete ground, etc. 8. Check the safety on the spot, there is no risk to the inspector, and there is no secondary damage to the cable. ⒐ high quality and low price are acceptable to ordinary customers. We know that the insulation layer of cable is relatively low. In addition, the electric flow is very large in the whole process of operation, and there are significant characteristics after common faults. The actual classification is as follows: the first kind of common faults: a piece of cable is burned out or a phase is burned out. This kind of common faults lead to the posture of current relay on the distribution box, and the cable is seriously damaged at the common faults. The second type of common fault: short circuit fault of each phase of the cable. Similarly, this type of common fault causes the current relay and voltage relay on the distribution box to be in a bad position, and the cable is also seriously damaged at the common fault point (possibly caused by external force). The third type of common faults: the cable can only be short circuited in one phase, the current relay posture, and the common fault points are slightly damaged but significantly exposed. It may be due to the high voltage of this phase or the quality of the cable. The fourth type of common fault: internal short circuit fault of cable, no mark can be seen on the surface. This kind of common fault is generally caused by the quality of cable, which is relatively rare. Common faults of hn-213x cable can be easily detected by the fusion application of rangefinder and detector in mobile phone positioning system. In addition, the characteristics of different common faults and the length of cable can also be detected separately. The actual situation is as follows: the first type of common faults and the second type of common faults. If the cable is short (less than 500m), the common fault detector can be used to accurately locate the common faults immediately without the cooperation of the distance finder. The common fault points can be identified by stepping in the hand receiver along the relative path (the relative path can be measured while walking). The third type of common fault: because the cable is slightly damaged at the common fault point, the data signal sent by the transmitter leaks less here. When accurately locating the common fault with the detector, the marking scope is narrow. At this time, the distance between the common fault points can be measured with the distance meter, and then the accurate positioning with the detector is also very convenient. The fourth type of common fault: this type of common fault is the most difficult to predict among all cable faults at this stage. At this time, you can use a rangefinder to detect the cable on both sides of the cable, and then compare the detection results with the specific length, so that the common fault point can be defined in a small range (1-3m). At this time, dig the cable and find the problem, Or decisively cut off this section of cable (because the cable is very cheap, the insulation layer is low, and the connector is easy to do), or use a detector to select the audio frequency for accurate positioning in this section, which can also identify the common fault points. At this stage, the cable fault detector based on impulse flashover method, which is applied by many customers of cable fault detector in power engineering, generally can use a distance meter to roughly measure the distance between common fault points when dealing with common faults of low resistance of cable and common faults of dead grounding device (the distance detection of such common fault points does not need high-voltage charging and discharging machinery and equipment, and the bottom pressure single pulse method is used) However, ignition, charging and discharging and listening to sound are still used for accurate positioning of common fault points. In addition, the relative Pathfinder of such instruments and equipment is separated from the designated instrument, which makes it impossible to specify the relative path at the same time when selecting the correct relative path, and usually deviates from the relative path when specifying. Moreover, due to the limitation of the basic principle, the relative Pathfinder of such instruments and equipment finds the relative path of the cable It is impossible to find the exact relative path of the cable when the cable is in the middle of the total width of 1-2m. Considering the applicability, hn-213x cable fault detector just fills the shortcomings of the application. It can accurately locate the common fault points of the cable, detect the buried depth and the relative path smoothly. The instruments and equipment are very vivid in the marking of common faults, relative path and buried depth No need to do technical index analysis or rely on the working experience of the operator. It makes the original complex fault test work become a relaxed and interesting thing. Therefore, many customers of impulse lightning cable tester can form a set of extreme low-voltage cable fault tester if they have another DW cable fault detector and the original distance finder. In addition, the The common faults of low resistance and short circuit of external high-voltage cable can also be specified quickly to improve the efficiency many times.
How to Ensure the Correctness of Cable Identification by Live Cable Identification Instrument
How to Ensure the Correctness of Cable Identification by Live Cable Identification Instrument
In the 21st century, with the rapid development of railway, the speed per hour is faster and faster, and the marshalling operation is more and more intensive, it is necessary to ensure the normal operation of electrical service system. How to ensure the correctness of cable identification by live cable identification instrument, we will discuss and explain this problem below. In the electrical service support, the fault and construction of signal cable shall be tested and identified quickly. If the identification is wrong, it will have a very serious impact and cause train accidents. So let's talk about the identification of electrical service system. 1、 Current situation and disadvantages of signal cable identification in telecommunication system target cable identification is required in field work such as emergency repair, relocation and replacement of signal cable. Since there is no suitable instrument, most of our signal cable maintainers use the following methods to identify. First, wait for the skylight point, and remove the signal cable sheath when the skylight point; Secondly, two core wires are selected as the identification wire, and the two core wires are also found at the end; Finally, use the blade to cut the skin of the selected two core wires for short connection, and use the external meter to measure whether the selected two core wires are short circuited at the end. If they are short circuited, it means that the identification is accurate, otherwise, the identification is wrong. However, there are many disadvantages in using this method for identification: 1. Generally, such work is rush repair, which must be completed in the skylight point. If it takes up the time in the skylight point for identification, the rush repair time will be greatly reduced, and some even need to apply for two skylight points to complete a work; 2. After the selected two core wires are short circuited, the two core wires found at the end may not correspond, resulting in wrong results; 3. The outer skin and copper shield of the cable shall be broken. After identification, this place shall be restored. In the future, this place is a joint and a potential fault point. 4. The most important thing is that this identification often produces wrong results, resulting in operation accidents. 2、 Current status of cable recognizer 1. Current status of identification equipment (identification and attached identification): status of identification 1: conventional cable recognizer is designed for power cable identification and is widely used in the power field. Whether imported or domestic, it has two service conditions: 1) it has high requirements for the loop resistance of the target cable, Generally, it shall not exceed 50 ohms. If it exceeds the range of this circuit resistance, the equipment will not work normally, which is beyond the range of equipment use; 2) Disconnect at least one end of the outer armor grounding (same as shielding grounding) at both ends of the target cable, so that the applied signal cannot return from the target cable. Therefore, this power cable identification instrument is not suitable for the identification of electrical signal cables. Identification status II. When promoting digital path tester, some manufacturers publicize that the equipment has identification function. In fact, when using the digital path tester to identify, if the receiver touches the identified cable, which signal is the strongest, that is the identified cable. This recognition method has a single judgment basis in recognition, only the signal size, no signal direction, and can not be used as the final judgment. Moreover, such equipment has great attenuation on the signal cable, and the identification of long-distance signal cable can not be done at all. 2. Conclusion: the use conditions of power cable identification instrument and digital path tester determine that these two types of equipment are not applicable to the signal cable of electrical service system. 1) For the signal cable of electric service. The cable is very long, with a length of more than 5km, and some can reach more than 20km; The wire core is very thin, generally 1mm ² , The resistance is 23.5 Ω per kilometer, and the cable body resistance of more than two kilometers has reached the critical value of equipment test, so the loop resistance problem has become a hard wound of the conventional identification instrument. 2) In the electrical service system, it is very inconvenient to open the outer armor grounding (the same as shielding grounding) of the signal cable. The regulations of each Railway Bureau and railway line are inconsistent. Some cannot be opened, some must be opened in the skylight point, and must be restored before the end of the skylight point. Based on the above two points, the conventional cable identifier and Pathfinder can not meet the requirements of signal cable identification of railway electrical service system. 3、 During the test of railway signaling cable identifier, the requirements for loop resistance can reach 1000 Ω, and there is no requirement for armored grounding or ungrounded of the target cable. The utility model solves the difficult problem of identifying the signaling cable. The railway communication cable is specially designed and can be used online. It has the characteristics of micro power transmitting signal, has no crosstalk and interference to the data transmission of adjacent cables, and accurately finds out the required cable. The size double jaw configuration can not only identify the cable, but also identify the wire pair in the cable. Color large screen LCD, live voice prompt, friendly intelligent man-machine interface, and its unique intelligent orientation can indicate the signal direction, which makes the operation simple and practical. It is especially suitable for field use. Even untrained personnel can use it quickly. Through live measurement, it is not necessary to apply for night skylight time to cut off and repair cables. Workers in the front-line electrical service workshop can measure during the day, including when high-speed rail / Bullet train passes, which improves the timeliness and operability of detection.
Cable Fault Tester
Cable Fault Tester
Cable fault detector can be seen everywhere in our daily life. Cable fault detector plays a lot of roles. Cables on the road can divert people and vehicles. The guardrail beside the river can protect people from falling into the river. The guardrail beside the lawn can protect the lawn from being trampled by animals and people. Therefore, the role of guardrail is still great, The installation of guardrail is also very important. The installation of river guardrail needs special attention. Let's follow the traffic guardrail manufacturer to see how to install River guardrail. The river guardrail is a guardrail product installed next to the river to prevent pedestrians on the river road from falling into the river. The base to be fixed during the installation of the river guardrail can only be in the original position, which may cause the base to not be fixed and lose the significance of setting the river guardrail. Simply put, it is to install the guardrail at an oblique angle, hit 2 Road nails to fix the base, and the remaining 2 nail holes are used for later maintenance. After the base of the river guardrail is fixed, the column is installed. Insert the column into the base, and then install the expansion screw. After the screw is fixed, two people need to cooperate when tightening the screw. One person holds the column to keep it vertical. When tightening the screw, the other person can tighten the screws at both ends. In this way, the column and base are installed. The next step is to install the guardrail piece. The steel connecting sleeve connects the river guardrail and the column. This is generally fixed on the column before leaving the factory, so as to reduce the on-site operation process of constructors. Align the guardrail piece with the upper and lower connecting sleeves of the column, and connect the left and right accurately. The above is the introduction to the steps of installing the river guardrail. When installing the river guardrail, we should follow the steps strictly and master the installation skills of the river guardrail, so that we can make fewer mistakes in installation and ensure the performance of the river guardrail in the process of use. We are a professional guardrail manufacturer. If you need to buy our guardrail products, you can call us to communicate with us.
How to Select the Appropriate Cable Fault Tester
How to Select the Appropriate Cable Fault Tester
Cables bear the great responsibility of transmitting electric energy, so it is very important to ensure the normal use of cables. What if the cable fails? This requires the use of cable fault tester to find out the fault point, and then repaired by professional staff. Different types of equipment have different configurations, so how to select the appropriate cable fault tester? Let's have a look. As the cable fault types are divided into high resistance, low resistance, broken wire and composite faults, the cable fault detectors sold in the market are generally high and low voltage complete sets, including many components and accessories. A set of equipment components are as few as 5-6 pieces and as many as 10-11 pieces. As a cable manufacturer, it is necessary to timely locate and deal with various cable faults in the production process in the plant to ensure timely delivery of products; At the same time, we should also take into account the location of sudden cable faults after the cable laying at the customer's site or during operation. Therefore, as a cable manufacturer, when purchasing the cable fault detector, it is a complete set of high and low voltage purchase configuration, and the equipment components are 6-10 pieces. In case of direct buried cable fault location at the customer's site, the handling and transportation of the whole set of equipment must be transported by a special cable fault detection vehicle, otherwise the transportation quality of the instrument is not guaranteed. There are also some special cable fault detectors, such as the railway household coat cable fault detector. More specifically, it can be called the railway single core cable outer sheath fault tester. These two configured cable fault testers are suitable for railway. According to the characteristics of railway cable outer sheath fault, under the condition of separation of cable sheath and shielding layer, The bridge method or voltage drop method is used to initially measure the grounding fault of the cable outer sheath, and then cooperate with the special receiver to accurately find the fault point. The instrument has a built-in high-precision measurement unit. If there is a good auxiliary cable sheath, the fault is initially measured by the bridge method. Without moving the instrument to the opposite end, the test instrument can directly display the fault distance and realize rapid measurement. If there is no good auxiliary cable sheath, the fault distance of the outer sheath can also be calculated by testing both ends of the outer sheath of the faulty cable and using the resistance (voltage) comparison method, If the resistance value of the sheath per kilometer is known, the fault distance of the outer sheath can be calculated through the single end voltage drop test of the outer sheath of the faulty cable. The outer sheath transmitter and the fixed-point receiver can realize the accurate fixed-point of cable sheath grounding fault. At present, the cable fault detectors sold on the market are mainly divided into two types: one is the cable fault detector designed according to the principle of echo method: the components mainly include intelligent waveform detection analyzer, Pathfinder, DC high-voltage generator (including console and AC / DC dual-purpose high-voltage test transformer), capacitance, ball gap, pointing instrument, etc. The second is a cable fault detector designed and manufactured according to the principle of bridge method: the components mainly include fault location bridge (high and low voltage bridge), pointing instrument, path instrument, wave reflection fault location instrument, etc.

What Are the Places Where High Voltage Power Cables Are Most Prone to Failure
What Are the Places Where High Voltage Power Cables Are Most Prone to Failure
We all know that the cable needs to pass the test when it is officially put into the mall. However, the functions and methods of different cable tests are also different. The test method of high-voltage power cable is flicker method. Flicker method includes impulse flash and direct flash. Impulse flash method is also the most commonly used test method. Due to the high precision of impulse flash test, its operation is simple, safe and reliable. The equipment of flicker method is composed of two parts. The high-voltage attack equipment is used to generate DC high voltage or impulse high voltage, which will be applied to the faulty high-voltage power cable. The discharge at the fault point will produce a reflected signal. The current pulse meter is used to pick up the fault interval of the reflected signal, measure some faults such as open circuit, short circuit or low resistance. Fault resistance is also the place where faults are most likely to occur. Based on this measurement method. (1) When the resistance at the fault point is immeasurable, the open circuit fault can be quickly found by measuring with low-voltage pulse method. Simple open circuit faults are not often seen. Open circuit faults are phase to ground or phase to phase high resistance faults, and phase to phase or phase to phase low resistance faults exist together. (2) When the resistance of the defect point is greater than zero and less than 150 kiloohm, the cause of the low resistance problem can be found at will by measuring with the low-voltage pulse method. (3) When the resistance at the fault point is equal to zero, the defect of measuring short circuit by low-voltage pulse method can be found, but this problem is rarely encountered. (4) Flashover defects can be measured by direct flashover method. This problem is usually caused by questionable joints. When the resistance of the fault point is greater than 150 kiloohm, the value changes greatly, so it is very uncertain during measurement. The measured interval is the interval from the fault point to the cable test end; Otherwise, it is the interval from the fault point to the opposite end of the cable test. (5) With the progress of high-voltage power cable fault test skills, different methods should be used for different power cables. We should constantly improve skills and equipment. This allows the safe use of high-voltage cable power for a long time.
Instructions for Use of Underground Pipeline Detector
Instructions for Use of Underground Pipeline Detector

The underground pipeline detector plays a positive role in improving the pipeline management level of relevant industries in China. The underground pipeline detector is composed of transmitter, receiver and accessories, which is used for accurate positioning, buried depth measurement and long-distance tracking of underground pipeline routing, as well as measurement and search of pipeline insulation fault points. The underground pipeline detector adopts multi coil electromagnetic technology, which improves the accuracy of pipeline positioning depth and the identification ability of target pipeline. It can also accurately track and locate the target pipeline in the area with dense and complex pipelines. The leakage current of the pipeline to the ground can be received by the two pins of the A-frame respectively, and the signal size displayed by the receiver is the difference between the received signals of the two pins. When the difference received by the two pins is zero, it indicates that the A-frame is directly above the fault point. Determine the wire path before fault location test. If there is abnormal signal loss during pipeline test, some signals may escape from the damaged insulation to the ground. When the path is determined and the general fault area is determined, cut off the connection point between the pipeline terminal and the ground to make the leakage current concentrate through the fault point. If the connection between the pipeline and the ground is disconnected, the current transmitted by the transmitter will flow out of the fault point, which will increase the escape of current at the fault point, which is conducive to fault location. Connect the transmitter to the cable, select the frequency as low frequency and the working mode as A-frame mode. Connect the receiver to the A-frame and insert the A-frame into the soil with appropriate force. Note: the underground pipeline detector receives the operation alarm of error current test. If a current reading of 000 is displayed during the current test, the receiver has detected an incorrect current reading. Check that the cable at the depth measuring point is straight at least 5m in front and behind. Check whether the signal within 10m is relatively stable, conduct depth measurement on both sides of the initial depth measurement point, and check whether there are adjacent interference pipes within 3-4m near the target cable. This is the most common cause of depth measurement error. Strong signals induced by adjacent pipelines may lead to 50% depth measurement error. For several depth measurements slightly deviated from the pipe position, the minimum depth reading is the most accurate, and the position indicated here is also the most accurate.
What Should Be Considered When Purchasing a Cable Fault Tester
What Should Be Considered When Purchasing a Cable Fault Tester
Cable fault tester is a common cable fault detection equipment, and its accuracy and detection speed are guaranteed. We are used to evaluating this thing before we buy it, from its performance, value, price and other aspects. After that, we will decide whether to buy it. So, what evaluation should be done when purchasing a cable fault tester? When selecting the cable fault tester, the cable fault tester needs to understand its performance. Is its overall performance stable, or is it convenient in the whole operation? If there are problems in the operation and unstable performance of the cable fault tester you choose, it will certainly lead to more problems in the whole use, not to mention that the cable fault tester you choose is a test suitable for your own use, which can not highlight its whole use value. Therefore, when selecting the cable fault tester, we should pay attention to these two points: 1. How about the performance? Before choosing a cable fault tester, you'd better understand and test several different cable fault testers, that is, find some early tests to see if they really have high usability. 2. Quickly detect the fault point and find the problem of your own equipment in a very short time, If you can, it can show that it is a very good cable fault test. If you can't meet this standard, you will waste more time and money, and the selected cable fault tester will not be suitable for your own use. Therefore, we can understand how to select a more appropriate cable fault tester. After selecting an efficient and suitable cable fault tester, the next step is how to use it. What if you can better operate the cable fault tester to enable you to quickly detect the fault point? 1. Understand the instructions of the cable fault tester. After you get a cable fault tester, you need to understand its operating instructions before preparing for operation. Some people feel that they have a certain understanding of the cable, so it is not necessary to understand its operating instructions when using it. In fact, this is not the case, Most of the time, my knowledge is very different from professional operation, so I can understand the contents of the operation manual in advance before use, which naturally has a very good guarantee for the whole operation after use. 2. Check the circuit. When using the cable fault tester, do you need to test in advance or find out if there is a problem with its circuit connection? If there is a problem that needs troubleshooting, you also need to know whether the whole connection is normal in advance, so as to have higher detection efficiency in the whole detection, know the problem of cable fault, and find a good solution, so as to ensure the working performance of the whole power system. Generally speaking, after the carefully selected cable fault tester, the equipment performance of the cable fault tester is guaranteed. In the process of cable fault detection, the corresponding fault results can be obtained according to the fault performance in the operation manual.
