摘　　要：由于配网绝缘水平低,雷击跳闸和导线雷击断线事故时有发生,而现有的防雷措施在一定程度上减少了绝缘导线雷击断线事故的发生,但仍会出现绝缘导线断线事故。本文通过对某地区绝缘导线断线问题及其防雷措施进行分析,针对该地区防雷措施存在的不足,提出一种性能较佳的防雷措施并进行应用,表明能够有效减少雷击跳闸和导线雷击断线问题。Due to the low insulation level of distribution network,lightning trip and wire breakage accidents often occur,and the existing lightning protection measures reduce the occurrence of lightning breakage accidents of insulated wires to a certain extent,but there will still be insulation wire breakage accidents.Based on the analysis of the problems and lightning protection measures of the insulated wire in a certain area,a better lightning protection measure is proposed and applied,which shows that it can effectively reduce the problems of lightning trip and lightning break of the wire.
