架空输电线路的运行维护

Operation and Maintenance of Overhead Transmission Line

架空输电线路是将不同地区的发电厂、变电站、负荷点连接起来，起输送或交换电能作用的线路。由于架空线路暴露在大气环境中，易受到雷电袭击、雨淋、湿雾以及自然和工业污秽等造成停电事故。因此，加强架空输电线路的运行维护具有重要的意义。

Overhead transmission line is connecting the power plant, transformer substation, load point in different regions, designed for conveyance or exchange of electric energy. Bec- ause the overhead line is exposed to the atmosphere, it is often caused blackouts due to lightning, rain, wet fog and natural and industrial polution. Therefore, it is of important significa- nce to strengthen the maintenance operation of overhead tran- smission lines.
