摘　　要：通过雷电定位系统、故障录波系统、杆塔结构信息、地形地貌信息、气候环境信息、雷电活动信息等数据,制定了一套精细化的输电线路雷击故障分析方法,能够实现对雷击故障杆塔的高效定位,确定造成雷击故障的主要因素,最终达到对雷击性质的准确判断,实现雷击故障点的复现,为线路的防雷改造提供必要的技术指导。A set of elaborate analysis method for transmission line lightning failure is established via lightning location system, fault recording system, information of tower structure, topography and geomorphology, climate environment, lightning activity et al. By the method proposed in this paper, efficient location of lightning failure tower can be realized, and the main factors that cause lightning failure can be determined, finally identification of shielding failure and back striking, and the replay of lightning fault point is realized, which can provide essential technical guidance for transmission lines lightning protection renovation.
