摘　　要：针对某500kV变电站66kV干式空心并联电抗器发生的贯穿性绝缘故障,进行整体试验和解体分析,认为大量鸟粪附着在电抗器包封间通风道表面、致使表面绝缘降低、以及设备本身设计的绝缘层薄弱是造成该设备绝缘故障的主要原因,提出处理措施,对解决并联电抗器绝缘故障有一定指导意义。Through the integral testing and collapsing analysis,it is pointed that the reducing of surface insulation because of a large number of birds droppings＇ attaching to the surface of ventilating duct between interlayer and the weakness of insulating layer are the main reasons of 66 kV dry-type air core shunt reactor penetrability insulation fault in 500 kV transformer substation.On this basis,solutions have been proposed,which have a certain significance to solve the penetrability insulation fault of dry-type air core shunt reactor.
