摘要

GIS在电力系统中已广泛应用

但运行中产生的局部放电严重影响设备的绝缘性能

因而需要加强对GIS中局部放电检测的研究。文中通过对一起220 kV GIS局部放电检测案例分析

综合运用特高频、超声波局部放电检测及SF6气体分解物测试等多种带电检测方法

准确判断了局部放电类型并对故障位置进行了定位

通过解体检查证明了带电检测判断结果的正确性

确定了等电位弹簧失效是产生局部放电的原因。最后提出应重视对GIS局部放电在线监测信息的甄别

综合判断设备运行情况。

Abstract

GIS is widely used in electric power system

however

the problem of partial discharge during operation seriously affects the insulation property of equipment

thus need to strengthen the study of partial discharge detection in GIS.A fault of partial discharge in the 220 kV GIS equipment is analyzed.Combined with several kinds of live detection methods such as ultra-high frequency and acoustic emission partial discharge detection and SF6 gas decomposition test

the partial discharge in the GIS is judged and positioned

while the judgment result of live detection has been proved accurately by disassembling check.The partial discharge fault is caused by failure of equipotential spring.In addition

the GIS partial discharge on-line monitoring information should pay more attention and apply to comprehensive judgment of equipment operation.
