摘　　要：依托雷电定位系统(LLS)收集雷电参数,分析计算感应雷作用下正、负极性落雷时10kV架空绝缘配电线路雷击闪络率,并与实际线路雷击跳闸情况进行比较分析。提出综合考虑运用支柱绝缘子配合穿刺型防弧金具、串联外间隙氧化锌避雷器来提高10kV架空绝缘线路耐雷水平,防止雷击断线。Based on the LLS,the lightning parameters were collected.The flashover rates of the 10kV overhead insulation line caused by inductive overvoltage from positive and negative lightning were calculated.Then,the flashover rates and the statistical lightning trip-out rates of the line were analyzed in a comparative way.This essay proposes that the pillar insulator with arc-protection hardware with stabs and the metal oxide surge arrester with series gaps be used appropriately to improve the lightning resistance of the 10kV line and prevent lightning breaks.
