摘要
输电线路跳闸原因约有60%是因为雷击输电线路引起的,所以,采用线路型避雷器降低线路的雷击跳闸率是很有必要的。为此,对线路型避雷器分类作了介绍,并对各类线路型避雷器原理及应用作了详尽的介绍分析。从已安装了线路型避雷器的输电线路运行情况来看,线路型避雷器在输电线路防雷及变电站防止雷电侵入波方面发挥了重要的作用。
Sixty percent of transmission line tripping failures are caused by lightning strikes. Consequently, it is necessary to use line arresters to reduce the line tripping rate with lightning strike. This paper describes the types, principle and application of line arresters in detail. Operation results of transmission lines equipped with line arresters show that line arresters play an important role in the lightning protection of transmission lines and the incoming surge prevention of substations.
