摘要

笔者介绍了10 kV开关柜局部放电带电测试的地电波和超声波原理

并且成功检测出了深圳110 kV田面变电站10 kV 2号站用变柜ST2存在局部放电信号

同时通过对ST2柜的停电检查

发现ST2柜中的A相MOA是产生局部放电信号的源头所在

从而验证了采用地电波和超声波这两种原理相结合的方式检测10 kV开关柜故障的有效性

为较早地发现10 kV开关柜中的设备缺陷提供了有效检测方法和依据。

Abstract

The principles of TEV and ultrasonic detections for partial discharge（PD） signal in 10 kV switchgear were explained.A PD signal in the 10 kV ST2 switchgear of 110 kV Shenzhen Tianmian Station was successfully detected with the two detection methods

and through power-off check

the PD source was found on the MOA of phase A.This case proves that the combination of both methods is effective in detecting switchgear defects

which may provide an effective way to promptly finding defects in 10 kV switchgear.
