摘　　要：随着近几年GIS设备的广泛投用,其在运行中发生故障的情况越来越多,笔者应用便携式色谱仪及SF6分解气体快速测试仪对现场SF6气体分解物进行了测试,例举了几起500 kV变电站GIS设备故障状态下的SF6气体色谱分析图和SF6气体分解物组分含量数据表,结合实例初步探讨了GIS设备几种不同故障类型与SF6气体分解物之间的关系,为准确诊断GIS设备运行状态提供了宝贵经验,该工作还需今后进一步论证与实践检验。SF6 gas decomposition products of GIS equipment were detected on the spot with a portable chromatograph and a quick tester of SF6 gas decomposition products. The chromatograms and concentration tables of SF6 gas decomposition components for several different failures of GIS equipment in a 500 kV substation are given to explore the relationship between different GIS equipment fault types and SF6 gas decomposition products for the purpose of accurate fault diagnosis of the GIS equioment.
