摘要
本文对原规程［１］中输电线路防雷计算的雷电流幅值累积概率分布、对地雷击密度、线路收集雷击宽度和雷击有避雷线线路绝缘上所受电压的计算方法等提出了修订建议。修改后的计算方法所得结果与输电线路雷击跳闸的运行经验统计值是一致的。
A suggestion on revising the calculationmethod in current regulation and some parameters used inlightning protection of transmission lines, such as cumulative probability distribution of current magnitude of lightning stroke, the ground-flash density (strokes/km2·a), thewidth of collecting lightning stroke by lines is put forwardin this paper. The calculation results of revised method forestimating the lightning performances of transmission linesare coincided with the practical cut-off statistics of transmission lines caused by lightning strokes.
