摘　　要：本文根据1例隔离开关内部接触不良导致的发热缺陷,结合其他带电检测手段及其负载情况,进行了综合分析,认为该类缺陷应结合特高频、超声波局部放电和SF6气体分析结果,判断其是否存在放电性缺陷,且应加强跟踪检测,防止因接触不良而导致悬浮、自由颗粒或尖端等放电缺陷;同时,分析缺陷发热严重程度时应综合考虑罐体结构、气室大小以及负载情况等因素。The paper analyzes the heating defect caused by poor contact in the disconnection switch combined with other on-line detection means and charged load . The article considers that it is necessary to judge whether there are discharged defects according to super high frequency , ultrasonic partial discharge and SF6 gas analysis results . The tracking detection should be strengthened to avoid suspension , free particles or tip discharge defect due to bad contact. The analysis of defect severity should be analyzed combining with the structure , size of the tank and the charged load .
