摘　　要：针对两起550kV GIS不同带电设备产生的异常现象,通过特高频、超声波、红外成像、SF6气体成分等带电测试方法进行全方位、多角度分析与对比。结果表明:磁致伸缩引起的机械振动不会给GIS设备运行带来危害,但机械振动放电引起的异常现象将会对GIS安全运行带来一定程度的危险。Aiming at two cases of different live equipment abnormality for 550 kV gas insulator switchgear （GIS）, analyzes and compares fully the live test methods of ultrahigh frequency, ultrasonic wave, infrared imaging and SF6 gas component, etc. The result shows that： the mechanical vibration caused by magnetostriction can not bring harm for GIS equipment operation, but mechanical vibration discharged caused abnormality can bring a certain degree of risk for GIS safe operation.
