摘　　要：随着GIS在各级电网的广泛应用,运行中的各类缺陷也随之增加,其中外部导流排异常发热是一种较为常见的问题,外部环流是该类问题发生的先决条件。文中结合红外测温发现的几起异常发热实例,分析了缺陷原因并提出处理措施,为该类问题的分析提供借鉴和技术支撑。With the widespread application of gas insulated switchgear(GIS)in power grid,number of its defects increases,the external overheat is a common problem.Circulating current on the surface of GIS enclosure is a prerequisite for overheat.The reason of several external overheat instances of infrared temperature measurement are introduced,the treatment measures are presented,which provide useful reference and technical supports for the analysis of this problem.
