山东省输电线路雷击跳闸分析及反措

The Analysis of the Lightning Trip-out of Transmission Line in Shandong Province in 2001 and the Lightning Protection

调查了山东省 2 0 0 1年输电线路雷击跳闸的情况及分布 ,分析认为绕击是造成输电线路雷击跳闸的主要原因。该省线路雷击跳闸率满足部颁规程要求 ,在全国输电线路中雷击跳闸率也是较低的。对多雷区易击点和山区线路易击段采用有效的防雷措施 。

This paper discussed about the transmission line trip-out due to lightning in Shandong province this year. Analyzed the reason of the transmission line trip-out and found out that the shield failure is the main reason. The lightning trip-out rate of Shandong province transmission line meets the demand of ministry regulation and it is lower than the average trip-out rate of transmission line in China. With the lightning protection in the heavy lightning area the running reliability of transmission line will be improved.
