摘　　要：文章以避雷线、导线的雷电击距及引雷角相等,分析了110～500 kV输电线路绕击雷害,并提出了确定110～500kV输电线路避雷线的引雷范围、保护范围、绕击范围的方法。分析计算结果表明:110～500kV输电线路的绕击雷害与线路附近及档距中央导线下方的凸出地形、树木、建筑物,以及避雷线对导线的保护角、避雷线与导线之间的垂直距离等有关。Based on the thunder-struck distance and lightning drawing angle phase the author analyzed the surround thunder-struck of 110- 500 kV transmission lines and put forward the method to determine the lightning drawing range of the ground wire, protective range and surround thunder-struck range for 110-500 kV transmission lines. The analyzed and calculated results have proved that the surround thunder-struck has relations to the convex topography, wood, buildings near to the lines and under the central conductor of the span, protective angle of ground wire to the conductor, vertical distance between the ground wire and conductor.
