    摘 要:通过带电检测发现体育下注平台体绝缘金属封闭开关设备(GIS)存在局部放电信号后,需对局放源进行快速准确定位,以判断缺陷类型,制定检修消缺方案。对GIS设备超声波定位、特高频定位、声电联合定位等方法进行了分析,并例举现场定位应用案例,案例表明三种定位方法对GIS一般缺陷都有良好的定位效果。对于超声波或特高频难以定位的缺陷,可以采用声电联合定位法同时分析超声波与特高频信号,实现缺陷准确定位。

    Abstract: After the partial discharge (PD) signals in gas insulated switchgear (GIS) were detected, it is necessary to locate the PD sources quickly and accurately, so as to judge the types of defects and to formulate a solution for eliminating the defects. This paper analyzed the methods of ultrasonic localization, ultrahigh frequency (UHF) localization, and acoustoelectric union localization of GIS equipment and illustrated the application cases of field localization. The cases show that the three localization methods have good location effect on general defects in GIS. For the defect that ultrasonic or UHF localization method is difficult to locate, the acoustoelectric union localization method can be adopted to simultaneously analyze ultrasonic and UHF signals to realize the defect localization accurately.
    Key words: gas insulated switchgear; localization; ultrasonic; ultrahigh frequency; acoustoelectric union
