摘要
针对一起330 kV GIS设备超声波检测结果异常,特高频检测结果无特征信号的现象,运用多种带电检测方法对异常部位进行了综合诊断检测,分析故障原因是由于母线气室支撑绝缘子螺栓松动引起的悬浮放电。
For 330 kv GIS abnormal ultrasonic testing equipment,with UHF detection without the characteristic signal,using a variety of electric testing method has carried on the comprehensive diagnostic tests to abnormal spot,and analysis the cause of the problem was caused by bolt looseness busbar chamber support insulator suspension discharge.
