摘　　要：本文介绍了GIS(Gas Insulated Switchgear)内部局部放电缺陷的综合诊断方法(超高频局部放电检测、超声波局部放电检测、SF6分解物测试),通过工作中大量实践对几种方法的性能做了对比与探讨。以现场一起故障的定位和分析为例,提出了SF6分解物测试和其他两种方法可以互相佐证,提高检测准确性。最后对局部放电检测技术的深入应用进行了展望。This article describes the comprehensive diagnosis（UHF partial discharge detection, ultrasonic partial discharge detection, SF6 decomposition test） of the GIS （Gas Insulated Switchgear） internal partial discharge defect. Through work in a lot of practice, the performance of several ways to make a compared and discussion. On-site with the fault location and analysis, testing of SF6 decomposition products and the other two methods can be corroborated each other to improve the detection accuracy. Looking in-depth application of partial discharge detection techniques.
