摘要(Abstract):
绝缘子污闪是导致输电线路发生跳闸故障的主要原因之一,采用带电水冲洗作业可以有效避免绝缘子污闪事故。对220 kV输电线路的水冲洗已总结出一套行之有效的方法,而500 kV输电线路带电水冲洗目前还是空白。介绍500 kV输电线路带电水冲洗的具体工艺和操作实践,为今后开展500kV输电线路带电水冲洗作业提供参考。
Pollution flashover of insulators is one of the major reasons that cause trip fault of transmission lines. Live water washing can solve the pollution flashover of insulators effectively. This paper introduces the specific process and operation practice of live water washing on 500 kV transmission lines, which can provide reference to live water washing on 500 kV transmission lines in future.
