摘要
220kV输电线路大(外)转角耐张塔跳线在大风等恶劣气象条件下不能保证跳线距塔身的安全距离,易造成风偏跳闸故障,严重影响到电力系统的安全稳定运行。文中介绍的耐张塔跳线加装玻璃钢绝缘子能有效地控制在大风等恶劣气象条件下的跳线风偏跳闸故障,是一种有效的反事故措施,其经济效益和社会效益显著。
Under the bad weather such like gale, leap lines of the big strain resistant corner tower on 200 kV transmission lines can＇t guarantee the safe distance from leap lines to tower body , and it＇s easy to caused windage yaw trip, seriously affects the electric power system security stable operation. This article introduces strain resistant tower leap lines which added the glass fiber insulator to be able effectively to control the windage yaw trip accident in the gale and other bad meteorological condition .It is one kind of effective antiaccident measure, and its economic efficiency and the social efficiency are remarkable.
