摘　　要：对2014年迎峰度夏期间江苏省雷电活动进行统计,分析了落雷次数及地域分布变化趋势;结合各单位上报数据及雷电定位系统监测记录,多角度分析江苏电网220 kV及以上线路发生雷击跳闸次数及变化趋势、雷击形式、雷击杆塔结构特征以及江苏电网雷击跳闸原因,并从接地电阻测量、综合防雷措施应用、GIS系统及雷电定位系统数据录入管理等方面提出防雷工作建议。This paper presents a statistical analysis on lightning activities in Jiangsu province in 2014. The trend of lightning times and geographical distributions is analyzed. Combined with the lightning location system recording data, the lightning trip times, trends, failure forms and lightning tower structural features are analyzed, and the reasons for all the lightning trip cases are obtained. Lightning protection suggestions for earth resistance measurement, comprehensive lightning protection measures application, GIS systems and lightning location system data arranging are provided.
