摘要
为掌握贵州地区雷电活动的分布规律,以贵州省雷电定位系统监测的2006～2008年数据为基础资料,采用网格法对贵州省的雷电日、地闪密度等雷电参数进行统计分析,探讨了雷电流幅值分布规律,并提出了贵州省雷电流幅值累积概率分布计算公式,为贵州省山区输电线路防雷工作提供了科学依据。
In order to master the distribution law of lightning activity in Guizhou region,this article takes the lightning location system of Guizhou for monitoring data in 2006-2008 as a basic data.The grid method is applied to statistical analysis the lightning parameters,such as thunder day,ground lightning density in Guizhou Province.And then it discusses the distribution law of lightning current amplitude and puts forward calculation formula of lightning current amplitude cumulative probability distribution in Guizhou Province,which provides scientific basis for transmission line lightning protection project in Guizhou region.
