摘要
根据一系列简单计算结果对220 kV后荷甲线42号塔的一次雷击跳闸进行比较分析,找出了该次雷击跳闸的原因。结合线路运行实践,提出了较为合理的杆塔防雷改进措施。
Basing on the results of series simple calculation,comparative analysis on a lightning tripping of tower No.42 of 220 kV Houhe transmission line circuit I,the reason of this lightning tripping is drawn.Combining with the transmission line operating practice,a reasonable measure for improving the lightning withstand of tower is put forward.
