摘要
对2007-2009年贵州山区雷暴日、地面落雷密度等雷电参数以及110~500kV输电线路雷击跳闸情况进行统计分析,指出贵州山区雷电活动活跃以及地表以岩石为主是贵州电网输电线路雷击跳闸率高的主要原因,并提出防雷工作存在的问题以及下阶段防雷工作建议。
Based on the parameter statistics of thunderstorm days and lightning density and lightning - stroke trip - out situation of power transmission line in Guizhou from 2007 to 2009, the paper indicates that active lightning activity and main surface of rock are the reason of high lightning - stoke trip - out rate. At last, problems in existence and proposal for future lightning - protection work of Guizhou power grid are proposed.
