变电所直流电源柜接地故障的分析及处理

Analysis and Treatment of Grounding Fault of DC Power Cabinet in Substation

高压开关柜是变电所的主要供电设备,而直流电源柜输出直流电,给高压开关柜的操作系统提供电源。本文介绍了直流电源柜接地的分类和原因,阐述了查找直流电源柜接地故障点的常用方法和技巧,并结合实例,分析如何快速做好接地故障处理,确保直流电源柜设备良好运行。

The high-voltage switchgear is the main power supply equipment of the substation,and the DC power cabi⁃net outputs DC power to provide power to the operating system of the high-voltage switchgear.This paper introduced the classification and causes of the DC power cabinet grounding,explained the common methods and techniques for finding the ground fault point of the DC power cabinet,and combined with examples to analyze how to deal with the ground fault quickly to ensure the good operation of DC power cabinet equipment.
