摘　　要：研制了气体绝缘组合电器(GIS)局部放电检测的圆板和圆环型两种内置传感器,分析了它的频率响应特性以及稳、暂态的输入输出特性。人工模拟缺陷下局放信号的实测结果表明,所研制的传感器性能可靠、灵敏度高,可用于GIS局部放电的测量。Based on the characteristics of configuration of gas-insulated substations (GIS) and partial discharge in GIS, a disc coupler and a loop coupler for continuous monitoring partial discharge in GIS is designed and the response characteristics of two couplers are investigated. The results of PD signal measured by the couplers in GIS are given, and it is shown that the designed couplers can be used in the measurement of partial discharge in GIS.
