摘　　要：针对传统输电线路防雷评估针对性不强的问题,提出采用雷电定位系统积累的监测数据统计数据,考虑雷电活动在时间和空间上的差异性,为准确的评估输电线路防雷风险奠定了基础;引入了风险评估的思想,制定输电线路雷击闪络风险分级方法,对输电线路逐基杆塔进行风险等级划分,对提高雷电防护的针对性和有效性具有重要意义。Against the scattershot evaluation of the traditional lightning protection for electric power transmission line,based the statistical analysis result of the lightning monitoring data from the lightning location system and the consideration on the difference of the lightning events in time and space,this paper introduces the risk assessment idea and proposes classification method for the electric power transmission line lightning flashover risk,classifies the flashover risk by lightning over electric power transmission line by each tower,helpful and significant realistically to improve the effectiveness and the pertinence of the lightning protection.
