气体分析技术在GIS故障定位和故障类型判断中的应用

The Application of Gas Analysis Technology to Fault Location and Fault Diagnosis of GIS

笔者采用气体分析技术对一起GIS事故进行了分析、判断,通过检测管技术确定了故障气室;应用离子色谱法、GC-FTIR联用法、气相色谱法对相关气室的气体进行了分析。通过该事例研究了故障下GIS中气体成分的变化情况,探讨了故障下GIS中气体成分变化与故障性质的关系。

A GIS incident is analyzed with gas analysis technology, and the fault chamber is determined by using detecting tube technique. The gas in the gas chambers concerned are analyzed by ion chromatography, GC-FTIR method, and gas chromatography. This case study also probes into the variation of the gas in a damaged GIS and the relation between the gas variation and failure causes.
