分析了2005-2012年广东雷电活动规律及雷击跳闸情况，表明各年50%概率雷电流幅值集中在26~35 kA之间，雷击跳闸率受50%概率雷电流幅值的影响较地闪密度大；同塔多回输电线路雷击同时跳闸占雷击跳闸比例达15%~30%。提出了防雷策略，包括输电线路防雷需要抓住重点，转变观念，加强管理；重视常规防雷措施的基础上，重点治理易击重要线路和同塔架设线路，提高线路雷击跳闸重合成功率。

This paper analyzes thunder and lightning activity routines and lightning trip-out in Guangdong province during 2005-2012 and the conclusion indicates that 50% probability lightning current amplitude of each year is concentrating with-in 26~35 kA.In addition,impact of 50% probability lightning current amplitude on lightning trip-out rate is greater than that of lightning density and simultaneous trip-out rate of multi-circuit power transmission lines is holding 15%~30% among lightning trip-out rate.It proposes lightning protection strategies which require concentrate on crucial points,change ideas and strengthen management.Meanwhile,it requires emphasize for governing important lines and erected lines on the same tower which are easy to be stroke on the basis of paying attention to conventional lightning protection measures in order to improve success rate of lightning trip-out overlap.
