摘要
根据我国超高压变电设备的运行经验，简要介绍污秽条件下大型套管的雨闪特点、机理和试验方法；强调指出，在保证爬距的同时，超高压变电设备污秽外绝缘设计的重点是防止大型套管的雨闪。
According to the operation experience of the UHV transformation equipment in China the characteristics the mechanism and the testing method of big bushing flashover under heavy rain and pollution conditions are introduced． The focal point of external insulation design of the UHV transformation equipment is against the heavy rain flashover of big bushing．
