摘　　要：介绍了特高频和超声波在GIS缺陷检测中的联合诊断方法,现场应用该方法成功发现GIS内部局部放电缺陷,并采用时差法对放电源进行定位,最终准确找到并解体消除缺陷,避免严重事故的发生。现场应用表明,该方法能有效地诊断出GIS内部缺陷。The combined diagnostic method for partial discharge （PD） detection of gas insulated switchgear （GIS ） is presented in this paper . The inner fault of GIS was found by the combined diagnostic method , the discharge power was located by the time difference method , and the potential defect is eliminated in the end to prevent serious accidents. The live application shows that the method presented in the paper can diagnose the defects in GIS more successfully .
