How to Use the Wire and Cable Fault Tester to Quickly Find the Fault Point
How to Use the Wire and Cable Fault Tester to Quickly Find the Fault Point
In case of cable fault, power workers usually need to use cable fault tester to determine the location of fault point, so as to facilitate power workers to maintain cables. What problems should be paid attention to when using wire and cable fault tester to test fault points? Xiaobian summarized the following points on this issue. I hope you can solve your doubts and answer questions. Interested friends can have a look. 1. The gap between the discharge balls should not be increased. After using the cable fault comprehensive tester to roughly test the position of the fault point, if the gap between the discharge balls is adjusted too large, the impulse voltage will become higher, the high-voltage impulse time is too long, the fault point will be short circuited, the fault point will not discharge, and the fault point is difficult to find. Therefore, it should be noted that the gap between the discharge balls should not be adjusted too large. 2. In special cases, two fault testers can be used. If the soil layer is too thick, the surrounding environment has great interference, or the cable itself is damaged, resulting in weak vibration signal transmitted to the ground when the fault point is discharged, which makes it difficult to locate the fault point, two wire and cable fault testers can be used by taking advantage of the simultaneous occurrence of vibration wave and electromagnetic wave generated during fault click discharge. Use the probe and the probe to work at the fixed point at the same time. When two instruments hear a bang at the same time, and then find the sound point, we can accurately find the location of the fault point. 3. How to find the loudest point at the fixed point: after hearing the regular discharge sound, move the tester back and forth along the direction of the cable to find the position with large discharge sound. At this time, pay attention to reducing the output volume of the tester, and then slowly find the place with a loud sound. 4. Pay attention to replacing the battery. When the instrument is not in use, the power supply needs to be turned off in time. If the battery is low, the sensitivity of the instrument during test may be reduced, resulting in increased noise. Consider changing the battery at this time. 5. Check the wiring. If the shielding layer of the input line of the instrument is in poor contact, resulting in the sound of the radio station from the headset, you can check whether the wiring is correct. Precautions for cable laying: I. when using drainage pipes, the following provisions shall be observed: 1. The number of pipe holes shall be properly reserved according to the development needs. 2. For cables with large difference in conductor working temperature, different pipe banks should be set at appropriate spacing. C. the covering thickness of pipe top soil shall not be less than 0.5m. 3. The pipeline shall be placed on the leveled and compacted soil layer, and sufficient cushion blocks shall be provided to keep it continuous and straight; The longitudinal drainage gradient shall not be less than 0.2%. II. Requirements for cable wells. 1. Cable wells shall be set in the following parts of long cable ducts: (1) the limited distance of traction force between cables. (2) Cable branches and joints. (3) The direction of the pipeline changes greatly, or the cable goes directly underground through the drainage pipe. (4) The slope of the pipeline is large, and the fixation must be strengthened to prevent the cable from sliding. 2. Cable trench in power distribution room cable trench in power distribution room is generally used for incoming and outgoing lines of power distribution equipment, which is basically divided into under cabinet trench and double line trench. The cable trench wall is mu10 autoclaved lime brick, M5 cement sand, 1:2 cement mortar plastering of the trench wall, C20 concrete for coping and foundation, and channel steel shall be embedded under the equipment.
