摘要

目前对气体绝缘金属封闭开关（gas insulated switchgear

GIS）的故障研究大多集中在故障诊断与故障识别的层面上

缺乏对故障的系统研究。文中在分析研究大量GIS故障案例的基础上

从机械故障与绝缘故障两方面入手建立GIS故障树

并对GIS故障树进行定性与定量分析。通过对GIS故障树的定性分析发现制造与安装不当是引起GIS故障的主要原因

并且绝大多数故障是可控的。而对GIS故障树的定量分析主要针对常见绝缘缺陷的重要度研究。通过对GIS故障树的分析研究

为提高GIS可靠性

需要提高GIS的制造与安装质量

防止在制造与安装过程中留下故障隐患

同时需要对GIS的运行进行科学管理。

Abstract

The existing researches on the faults of gas insulated switchgear（GIS）focus mostly on fault diagnosis and identification

however

systematic researches are insufficient. In this paper

a GIS fault tree is established from two aspects of mechanical faults and insulation faults based on a lot of GIS fault cases

and the GIS fault tree is analyzed qualitatively and quantitatively. The qualitative analysis indicates that improper manufacture and installation are the main reasons of GIS faults

and most faults are controllable. The quantitative analysis focuses on the importance of insulation defects. It is concluded that to enhance the reliability of GIS

the manufacture and installation quality must be improved

and scientific management is necessary to be applied to GIS operation.
