摘要(Abstract)：

某126kV GIS气室内部有异常声响,经超声局放试验分析判定存在放电缺陷。通过开盖检查和分析,确定了造成振动和内部放电的主要原因是弹簧固定卡圈安装错误,对由此造成放电和振动的原因进行了分析。
This paper introduces that there is abnormal sound in the 126 kV GIS internal chamber.Through the ultrasonic wave partial discharge test,the existence of discharge defects is analyzed and judged.After opening chamber to examine and analysis,it is decided that error installation is the main reason of vibration and discharge inside.
