摘　　要：为了检测±1100kV昌吉换流站气体绝缘金属封闭组合电器(gas insulated substation简称GIS)设备安装后投运前检验其是否满足绝缘性能标准,同时检测GIS内部是否存在绝缘故障,故对800kVGIS设备进行交流耐压试验,最高试验电压为960kV;在试验过程中出现闪络放电现象,对出现闪络放电的原因进行分析,并确定放电位置,为后续±1100kV昌吉换流站GIS设备现场交流耐压试验提供技术支撑。In order to check whether ±1100 kV gas insulated substation equipment at Changji converter station meets the insulation performance standard after installation and commissioning,and whether there is an insulation fault inside the GIS,the AC voltage resistance test is carried out on the 800 kV GIS equipment and the maximum test voltage is 960 kV.The flashover phenomenon occurs during the test,and the reason is analyzed and the discharge position is determined,which provides the technical support for the on-site AC voltage resistance test of the follow-up GIS equipment at the Chang ji 1100 kV converter station.
