摘要

针对GIS中电压互感器中性点接地击穿同隙频繁击穿的现象

分析了击穿原因

指出击穿系由隔离开关操作引起的快速暂态过电压通过耦合电容的传遵而造成

并提出了经过实践检验的解决方法。

Abstract

The main Cause for breakdown freguently o ccuring in the gap of neutral point of PT in a 220kV GIS is the transient overvoltage raised by the disconnector operation and transmitted via the coupling capacitance between the primary and secondary windings ot PT

and one practical solution is also presented in this paper.
