随着铁路提速、电气化改造等工程的全面实施,沿线的高低压电力线路逐步实现电缆化,电力电缆的增长十分迅速,确保电力电缆的运行安全,及时排除故障,减少停电的时间和影响的范围对维护铁路运输生产秩序的稳定具有重大意义。因此,如何快速测寻电力电缆的故障成为铁路电力工程技术人员共同关注的问题。 With the full implementation of such projects as speed-raising and electrification of the railway, the high and low voltage power lines along the line are gradually being cabled. The growth of power cables is very rapid. The operation of the power cables is ensured safely, the faults are eliminated in time, the time of power outage and the scope of the impact are reduced It is of great significance to maintain the stability of railway transportation and production order. Therefore, how to quickly find fault in power cables has become a common concern of railway power engineering technicians.
