摘　　要：笔者对GIS常用的表带触头、弹簧触头、梅花触头进行了对比分析,并介绍了目前用于触头接触状况检测的回路电阻测试、振动法测试、局部放电测试、红外测温、SF6气体检测、光纤测温6种技术,同时结合典型案例分析了目前规程规定的检测方法即回路电阻测试所存在的问题,并据此提出大电流下进行回路电阻测试的建议。Spring contact, tulip contact and the watchband contact are often used in GIS. The advantages and the disadvantages are discussed in this paper. The common detection methods such as loop resistance, vibration method, PD detection, infrared temperature measurement, SF6 detection and optical fiber temperature measurement are also be introduced. Combined with typical case, problems of the detection method are introduced, based which the proposal of the resistance testing under high current is put forward.
