摘要(Abstract):
通过对浙江4个典型地区输电线路雷击跳闸与地闪密度的统计分析,指出了平原、高山、丘陵及沿海山岭等地形的地闪密度分布特点,以及各典型区域输电线路雷击跳闸与各级地闪密度的相关性,从而提出了不同地形区域差异化的防雷建议。
Based on statistical analysis of lightning trip-out of electric transmission line and ground flash density in four typical areas of Zhejiang,this paper points out that the distribution characteristics of ground flash density in different terrains including plains,mountains,hills,coastal mountains,and the correlation between lightning trip-out of electric transmission line and ground flash density in typical areas.And some suggestions are offered on lightning protection in different terrains.
