摘要(Abstract)：

雷击有可能造成双回线甚至多回线同时跳闸,对系统产生较大的冲击。结合某220kV同塔双回输电线路自投运以来多次发生同时雷击跳闸的情况,分析了历次雷击跳闸的原因和种类,提出了防止同塔双回输电线路雷击跳闸的措施。
Lightning stroke maybe induce double or more circuit transmission lines on the same tower to trip simultaneously, strike the power system badly. According to the operation experiences of lightning stroke tripping of 220 kV double circuit transmission lines on the same tower in a mountainous area of Zhejiang Province, the reasons and kinds of lightning stroke tripping every time are analyzed in the paper. Measures for preventing 220 kV double or more circuit transmission lines being tripped at the same time by lightning stroke are presented.
