一种新型配电网接地故障巡查设备在石泉供电分公司的应用

Application of a New Distribution Network Ground Fault Inspection Equipment in Shiquan Power Supply Branch

本文针对10k V配电线路长、分支多,接地故障点查找困难的实际问题,提出了一种简捷实用的接地故障定位新方法,并根据该原理研制了配电线路单相接地故障巡查设备。实际应用情况表明,该设备可以快速定位接地故障点,尤其可以对一些外部特征不明显的隐蔽接地故障点进行快速定位,具有很高的实用价值。

For the practical problems of 10kV distribution, such as, long lines, multi-branch, difficult to find ground fault, this paper proposes a simple and practical ground fault locating method, and develops single-phase ground fault inspection equipment of distribution line based on the principle. The actual application shows that the equipment can quickly locate the ground fault point, in particular, can quickly locate some hidden ground fault point without external characteristics, so it has high practical value.
