摘　　要：绝缘降低是GIS气体绝缘组合电器设备故障的主要原因,对GIS进行局部放电在线检测可有效掌握设备绝缘状况。本文分析SF_6气体分解物组份检测方法的原理,并搭建实验平台模拟几种典型绝缘故障,得出相应的检测频谱图。通过对检测频谱图分析,总结出该方法在GIS故障类型识别方面的特点,为后续GIS局部放电引起故障类型的研究提供参考。Insulation reduction is the main reason for the failure of the gas insulated switchgear. The insulation status of equipment can be controlled effectively by the GIS partial discharge on-line detection. In this paper, the principle of detection method of SF6 gas decomposition components is analyzed, and the experimental platform is built to simulate several typical insulation failures, and the corresponding detection spectrum is obtained. Through the analysis of the spectrum, the characteristics of the method are summarized, which provide a reference for the study of the fault type of the partial discharge in GIS.
