摘　　要：本文介绍了一起由于隔离开关合闸不到位引起的GIS内部发热并伴随局部放电的缺陷,运用超声波及特高频局部放电检测、红外测温、SF_6组分检测等技术进行了综合诊断,分析了造成缺陷的原因,对类似缺陷的处理具有一定的借鉴意义。This paper introduce an 110 kV GIS internal heat with partial discharge defects due to isolation switch was not in the right place, using ultrasonic detection method, the ultra-high frequency detection method and the analysis method to components of SF6 gas to detect the partial discharge. Analysis of the causes of defects, the processing has a certain reference to similar defect.
