摘　　要：从降低架空配电线路感应雷过电压的角度,分析了10 kV架空配电线路中导线三角形排列和垂直排列情况下耦合导线的安装位置.分析结果表明,无论大地是否为理想导体,耦合导线安装在架空配电线路相导线之间可以更有效地降低架空配电线路上的感应雷过电压.From the perspective of reducing lightning induced overvohage, this paper analyzes the installed position of a coupling line along 10 kV overhead lines when the lines are in triangular arrangement and vertical arrangement. The results show that coupling lines installed along overhead distribution lines can effectively reduce the lightning induced overvoltage of such lines no matter whether the ground is a perfect conductor.
