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.
What Are the Functions of the Cable Identifier
What Are the Functions of the Cable Identifier
1. Left and right direction indication: the left and right arrows show the cable position, which is convenient and intuitive. 2. Tracking error prompt: the innovative patented technology of AC signal direction measurement is used to eliminate the ground wire return and induced current interference of adjacent and cross pipelines. When correctly tracking the cable to be tested, the pointer points to the front; When tracking to the adjacent cable, the pointer will be backward and a question mark will be displayed to prompt the tracking error. 3. High anti-interference: the unique digital processing method can completely suppress the power frequency and harmonic interference of adjacent operating cables. 4. Sound prompt: when it is very close to the top of the cable, there is a sound prompt. 5. Single key measurement of pipeline depth and current intensity: it can directly read the depth value and the current carried by the cable. 6. Multiple detection methods: in addition to the traditional sound peak method and sound Valley method, innovative and accurate methods are especially provided. The sensing range of the traditional sound peak method is too large, which is not conducive to accurate detection. Although the sound Valley method is accurate, it can not distinguish the parallel cable. The accurate method has a very narrow response range, is very accurate, and can distinguish the parallel cable. It is a better way to find the path in the complex area of the pipeline. 7. Two active detection frequencies: 1kHz, suitable for basic off-line detection; 15KHz is suitable for special situations. 8. Passive detection: it can directly detect the running cable without connecting the signal generator, and can also be used to detect other pipelines. 9. Historical curve display: the screen displays the historical curve of signal amplitude to visually judge the signal change. 10. Uniqueness identification: the detection caliper is used to identify the uniqueness of the cable. Through the combined signal sent by the detection generator, the amplitude and direction of the current on the cable can be accurately measured, and the identification results can be clearly given. 11. Built in battery for easy replacement: built in Ni MH battery provides reliable charging mode. Rechargeable batteries and dry batteries can be used interchangeably and can be replaced easily. Even if the battery fails, it can be easily replaced without repair, and it is conducive to emergency use without timely charging. 12. Low power consumption and long battery life: the instrument can work continuously for more than 30 hours by using a fully charged Ni MH battery or a new alkaline battery. 13. Automatic shutdown function: when the instrument does not operate within 30 minutes, it will automatically shut down to reduce battery consumption; When the battery is under voltage, the instrument will also shut down automatically to protect the battery. 14. The casing is durable, light and easy to carry.
Cable Grounding Troubleshooting and Precautions
Cable Grounding Troubleshooting and Precautions
There are three main reasons for cable grounding fault. First, cable manufacturing defects are unqualified products; Second, poor operating environment, natural aging and external damage; Third, the installation is not standardized and the wiring is rough. There is only one root cause of grounding fault --- the insulating material of the cable. China's large-scale ground power stations are generally located in the West. These places are generally desert, saline alkali land, large temperature difference in the daytime, serious rat damage and very humid environment. For cable buried laying, the filling and excavation requirements of cable trench are relatively high; The operating environment of the distributed power station cable is no better than that of the above ground. The cable will bear a very high temperature, which is measured and controlled by technicians. The roof temperature can even reach the high temperature of 100-110 ℃. The fire and flame retardant requirements of the cable and the high temperature have a great impact on the insulation breakdown voltage of the cable. Therefore, the following points should be considered in the type selection design: 1. The insulation performance of the cable 2. The moisture-proof, cold proof and weather resistance of the cable 3. The heat-resistant and flame-retardant performance of the cable 4. The laying mode of the cable 5. The conductor material of the cable (copper core, aluminum alloy core and aluminum core) 6. The Section specification of the cable

Automatic Screwdriver Model Prototype
Automatic Screwdriver Model Prototype
This last week, I took on the challenge of designing and creating a low-fidelity model prototype of an automatic screwdriver with several features, such as an automatic screwdriver head selection mechanism and a screen which keeps track of how many screws have been screwed/unscrewed. The main goal was to make a tool designed like OXO, which is known for applying universal design principles to make well-designed and easy to use tools for cooking.PlanningTo start, I did a quick competitive analysis on other automatic screwdrivers to see what common design elements were used across this tool. Some were very simple and looked very similar to a normal screwdriver, but with a button to automatically unscrew/screw. Others were more advanced, having systems to change the overall shape of the screwdriver between a normal and a drill like shape or being turned on using a gyroscopic mechanism to tell which way you are turning the screwdriver. I really clung to the idea of being able to easily change between a traditional and drill shape, because that would make it a lot easier to use in several different positions and orientations. After deciding on my main design form, I wrote up a list of requirements that I wanted my design to be able to do. The main goal I had was for it to work and feel the exact same no matter shape it is in. To do this, I decided that the buttons, switches, and screens would work the exact same between the two different shapes. The most novel design choice that made this possible was to have 2 different screens: one on the end of the screwdriver that would be active when the screwdriver is in its normal shape and one in the middle of the screwdriver that becomes viewable when the screwdriver is in its drill shape. This way, the screen is easily viewable in both shapes, so the experience of using its features does not change between the two shapes. Though this may not be an especially cost-effective solution, it does make the screwdriver much more usable and adjustable. After deciding on my main requirements and design choices, I started to draw some quick sketches of how I wanted the screwdriver to look like. I also drew out what the different screens and touchable elements would look like.Initial PrototypeAfter drawing out my main ideas, I attempted to make my first prototype out of materials I had in my house, which only consisted of a few toilet paper rolls and a paper clip. I attached two toilet paper rolls with a paper clip, which I form to feel like a trigger, which would control the variable speed control. I also drew on buttons to act as a switch between screwing and unscrewing. I tried to use stick notes to imitate the screen, but they did not easily fit onto the ends of the toilet paper rolls. I tested this prototype in its different shapes and on different wall positions/orientations to confirm that the main actions (viewing the screen area, pressing the trigger, and switching the screwing direction) were easy to do while using it. I also made sure that these actions could be done easily whether the user was right or left handed.Second IterationOnce I confirmed the model and form was easy to handle and use in different positions, I reiterated on my prototype using stronger and more diverse building materials, like cardboard, tape, velcro, etc. In this iteration, I decided on the size of the model and the main types of buttons. The screwdriver is fairly large, but definitely still felt easy to grip, use, and easily access all the buttons/functionality. I felt like it would be large when actually created so that the top half could hold several different screwdriver heads and so that the screen would not be too small to see/interact with. I filled the empty middle parts of the model with pinecones to imitate the added weight and ability to tightly grip the model. I decided on a pressure-sensitive button for speed control instead of a trigger because it made the model easier to grip in different positions. I imitated this using a piece of paper that was scrunched to feel more like a spring. I made a switch using tape, paper, and a paper clip so that the user can easily switch between screwing and unscrewing during use. I made a hinge so that the model could easily switch between the two shapes, but it was slightly weak and did not hold its shape very well. I tried using magnets to have it hold its regular shape better, though they were not strong enough. I chose to do a final iteration of this design to fix this issue and to make it look cleaner overall.Final IterationMy final iteration cleaned up all the details from the second iteration and also created the main screens. In this iteration, I added colors to make it cleaner and signify the physical parts of the screwdriver you can interact with. I added velcro to the middle of the screwdriver so that the middle could easily change shapes and hold its form. I also added it to the bottom the bottom so that the model could easily fit into a new rechargeable stand I made for it. The velcro also had the added effect of making it easy to place and replace the paper screens I made to imitate the digital displays of the screwdriver. The digital displays would always be displayed on the screwdriver no matter what mode it was in. The digital display had two major functionalities: to allow the user to automatically change the screw head and to show the user the how many screws they have screwed/unscrewed. The head selection screen allowed the user to tap or swipe between different screw heads and different sizes for the screw heads. The screw counter screen allowed the user to see how many screws they had screwed/unscrewed, and reset each count individually on a button tap. The buttons at the bottom of each screen allow the user to easily switch between the two screens.User Test and CritiquesAfter completing my final iteration, I had a friend test out my prototype. First, I gave him the prototype and let him explore it and try and figure out what each major part of the screwdriver did. Then I gave him a fake task of trying to fix an amplifier using the model, with the added difficulty of starting out with the wrong screw head and size. He seemed to understand how to do the task and how to utilize my prototype to do so. This user test is available here. I also showcased my work to my class for feedback and critiques. For the most part, people thought my prototype was easy to use and enjoyed the novelty of it having two digital displays. Most people really liked that it was designed to be used in the same way for both different shapes. The only real critique I got was that one person could not easily grip the bottom. For a final product, I would make the bottom half get skinnier towards the middle while remaining larger at the ends. This way, it would be easier to grip while keeping the space at the ends necessary for the screens. Overall, I really enjoyed this exercise and the ability to iterate multiple times on my ideas. Using cardboard and other low-fidelity materials was really fun, but after seeing the creative ways my classmates utilized these materials, I think I could one day re-iterate on this project and make it look/feel even better

It is an activity that needs to be performed very carefully and must not be done in haste.The main purpose of the cable tester is to check the quality of a cable, whether it has any defects or if there are any loose connectors. When a cable fails, this can lead to fire or other forms of damage. Hence, it is important that the test results are accurate and accurate testing equipment should be used. Also, it must be mentioned that some cables fail because they are damaged during transit and not in use.The cable tester is a device that is capable of detecting a number of different kinds of faults in cables. This article will discuss the most common types of faults and what the cable tester can do to help diagnose them.Cable testers come in three types: video, audio, and fibre optic. Each type has its own set of specific characteristics and can be used to detect faults in your cables (see our article on each type). Here's a brief overview:
How to Use the Cable Identifier and How to Judge Whether the Cable Is Live
How to Use the Cable Identifier and How to Judge Whether the Cable Is Live
How does the cable identifier judge whether the cable is live? First: why should we judge that the cable is live: as an important instrument of power cable detection instrument, cable identification instrument has been used more and more widely. When there are multiple cables in the cable trench, it is necessary to identify a specific power-off cable, calibrate, move or cut off the cable, and other cables in the cable trench operate live, so the cable identification instrument shall be used for cable identification. Second: easy to use: compared with the cable fault tester, the use of the cable identification instrument is relatively simple. It is easier to use it by reading the instructions. Third: test example: since the cable shielding layer is usually connected to the ground, if other cables are also connected to the public ground in the cable bundle, the black output jack on the generator can be connected to the public ground, The return current is distributed in several cable shielding layers, and the return current is divided into many tributaries, which means that the difference current of the identified cable is large and the useful signal is clear. "Difference" means that the output current and its divided return current are in the same channel. As shown in Figure 4, there are 5 cables in Figure 4. Cable 4 needs to be identified. The "output current" of the cables to be identified is 20A. Assuming that the return current is evenly distributed among the shielding layers of all cables, there should be a return current of 4A in the cable to be measured. The difference in the cable to be identified is: 20A (output) - 4a (return) = 16A (difference). How to use the cable identification instrument I. working method of the cable identification instrument: the transmitter (host) is powered by 220V AC power supply, which is used for the power-off The cable to be identified, plus a fixed period, unipolar DC pulse signal. The output line of the transmitter is connected to the cable core and the grounding point or ground nail. The armor of the cable is disconnected from the earth, and the core is connected to the grounding point or ground nail at the far end. The loop can conduct pulse current, which can be read out by the meter on the receiver of the identifier. The current is determined by the loop resistance, and the loop resistance should be as small as possible. The wiring diagram of the identifier is shown in Figure 2. Note: during field use, if the grounding resistance is too small, the output current of the transmitter will also be large when the output adjustment knob is turned back to zero, and the protection circuit in the transmitter will act (shown as a small fast swing of the meter). At this time, the randomly configured 1 ohm 20W high-power resistor can be connected in series in the transmitter circuit. After the transmitter and receiver start working normally, the voltage induced in the sensor coil is displayed in the receiver header. The pointer swing direction of the header can display the current direction, that is, only the cable with current flowing out, the pointer deflects and swings greatly. This is the cable to be found. For all other cables, only the return current flows, the pointer deflects in the opposite direction and the swing is very small. The output adjustment knob on the receiver can adjust the signal strength. 2、 Wiring mode: 1. Before the test, cut off the tested cable, and the surrounding environment shall be in a safe state. 2. The generator is connected with the tested cable, and the red clip is connected with one or several cores of the identified cable. Connect the black clip to the ground nail. 3. Connect the core wire at the far end of the cable to the ground nail. 4. Disconnect the armor at both ends of the cable from the ground wire. 5. Plug the power cord into the power outlet. 3、 Identify the cable through the loop test. 1. In order to ensure the normal use of the instrument, pay attention to setting the test loop. 2. Connect the red output jack to the core of the cable to be identified, connect the black output jack to the ground, and connect the cable core to the ground at the far end. As shown in Figure 3, 3. The output current flows to the far end in the direction of the arrow in the cable, and all cores of the identified cable can be connected together through the earth return generator to obtain a clearer signal.
