How does the low-voltage cable fault indicator quickly detect the low-voltage cable fault point? In the specific work of the low-voltage cable fault indicator for many years, people have found that there are many differences in the common faults of high-voltage cables and low-voltage cables. The common faults of high resistance are divided into two categories: leakage and flashover; and common faults of cables can only be led by way, short circuit and open circuit (naturally, high-voltage cables also include these three conditions). In addition, the cable also has the following characteristics in the specific application process: 1. The blindness of laying is relatively large, and the relative path is not very clear. ⒉ When laying, it is not like the high-voltage cable line, which is filled with sand and bricks and then buried. On the contrary, the buried depth is shallow, and it is easy to be damaged by external force and cause common failures.
3. The cables are generally shorter, ranging from tens of meters to five hundred meters, unlike high-voltage cables, which usually range from five hundred meters to several kilometers. ⒋ The compressive strength of the insulating layer is low, and the processing technology is relatively simple when solving common faults as a connector. ⒌Most of the cables are often burnt and damaged at common fault points.
It is very rare that the common fault point does not leave imprints on the surface of the cable. ⒍The required load changes greatly, and the two colors are usually unbalanced, which is very easy to get hot, and the common faults caused by it are more common.
