摘　　要：对线路杆塔类型和线路地形进行了分类,分别评估了500kV、220kV、110kV等级各两条试点架空线路的雷击跳闸率,评估结果与线路的实际雷击跳闸率基本吻合。The paper analyzed the lightning performance of back striking and shielding of overhead transmission lines in Zhejiang Province,and assessed lightning trip-out rate of overhead lines of 500 kV,220 kV,110 kV,which have two lines on pilot study. The results of assessment are in good agreement of the actual lightning trip-out rate of lightning trip. The method of analysis of the lightning performance and assessment of lightning trip-out rate of overhead transmission lines has practical significance.
