摘　　要：绝缘导线因其良好的绝缘性和安全性,以及在防小动物和缓解线树矛盾方面的优异表现,在10 kV架空配电线路中得以大量使用。但随着10 kV架空配电线路绝缘化程度不断提升,雷击断线故障越来越突出,严重影响了电力设备安全稳定运行。本文结合一起10 kV绝缘架空导线雷击断线故障进行分析,根据现有配网防雷技术,提出防雷治理建议。Insulated conductors are widely used in 10 kV overhead distribution lines because of their good insulation and safety,and excellent performance in preventing small animals and alleviating the contradiction between lines and trees.However,with the continuous improvement of insulation degree of 10 kV overhead distribution lines,lightning bolt failure has become more and more prominent,which has seriously affected the safe and stable operation of power equipment.In this paper,a lightning bolt failure of 10 kV insulated overhead conductor is analyzed,and according to the existing lightning protection technology of distribution network,some lightning protection suggestions are put forward.
