摘　　要：近年来,随着电网规模的不断扩大,超高压变电站大量增加。由于环境和占地压力,大量气体绝缘金属封闭开关设备(GIS)被广泛应用于变电站建设,GIS越来越成为一种不可或缺的变电设备。剖析了在混合式组合电器(H-GIS)断路器导电回路电阻测量过程中易产生的误区,同时总结出一些正确的测量方法和注意事项,供处理类似问题时参考。In recent years,along with enlargement of the power grid scale,many EHV substations were built.Due to the pressures of environment protection and land occupation,a large quantity of gas insulated metal-enclosed switchgear( GIS) was widely used in substation construction.The GIS is becoming indispensable equipment for substations.A mistake,which easily occurs in resistance measurement of breaker conducting loop of the hybrid gas insulated switchgear( H-GIS),was analyzed,and some correct measurement methods and the matters needing attention in the measurement were summarized.The result in this paper can be used as reference for handling with similar problems.
