摘　　要：文章结合500kV及以下输电线路运行经验,总结了500kV及以下线路发生污闪的根本原因是输电线路外绝缘配置总体水平不足,并对500、1000kV交流输电线路污秽绝缘配置、爬电比距等问题提出了建议,并提出相关研究的课题。Combined with the operation experience of 500 kV and the below transmission line, this papersummarized that the external insulation disposition of transmission line is the prime cause of pollution flashover for 500 kV and the below transmission line. The suggestions about polluted insulation disposition, specific distance of creepage, number of piece in insulator string and length of string for 500 kV and 1 000 kV AC transmission line are put forward.
