[Abstract]In the entire power system, the role of the cable is quite huge, which can be said to be the aorta of the electrical system. Therefore, in the long-term operation process, due to the loss of its operation and various faults, certain problems will be caused to the cable, such as aging and overheating, which will cause the probability of power supply failure. Therefore, it is necessary to analyze the fault detection method of the power cable and take effective measures. In this article, firstly, the reasons and classification of 10 kV power cable faults are analyzed; secondly, the classification of 10 kV power cable faults is analyzed; finally, the method of power cable fault detection is researched.

在現阶段人们的工作和生活当中,电力成为了不可缺少的能源,因此电力系统的稳定运行对于人民的生活起到了至关重要的作用。在电力系统当中,电力电缆属于重要的组成部分,因此需要对电力电缆的正常使用运行进行分析。电力电缆是实现电力系统安全运行基础提供的保障和前提条件,但是在使用的过程中会出现一些故障现象,对于电力系统的正常运行起到了制约作用。因此需要对其采取合适的方式进行故障的检测,以此来避免电力电缆发生故障电力系统的稳定造成影响。
1 10 kV电力电缆故障的原因和分类
电力电缆故障原因可以分为四个方面,分别是机械损伤、绝缘受潮、电缆接头故障、绝缘老化变质。机械损伤属于电缆故障的常见事故,在安装时由于划伤、扭伤、打折、外力的破坏、建筑开挖、车辆碾压以及土地沉降等多个因素会造成电缆的接头和导体产生损伤现象。……
