摘　　要：基于对多种检测技术应用特点的分析,提出一种有无异常的快速巡检、电检测确认异常及部位、辅助检测分析印证异常的三步序综合判断GIS中局部放电缺陷的诊断策略。针对一起110 kV GIS的绝缘缺陷,遵循综合检测策略,进行了测试分析。测试结果验证了该综合诊断策略的有效性,为准确判断运行中的GIS绝缘缺陷提供了一种新的诊断策略。According to the analysis of application features for different detection techniques, the comprehensive diagnostic strategy of three step sequences is summarized focusing on rapid detection of exception, and confirming exception and position using electrical detection technology, and confirming exception again using assisted detection technology. An insulation defect of 110 kV GIS is tested and analyzed following the comprehensive diagnostic strategy. The results verify the effectiveness of the comprehensive diagnostic strategy which provides a new comprehensive diagnostic strategy for insulation defects diagnosis to GIS in operation.
