摘　　要：指出500 kV紧凑型输电线路导线与塔窗的空气间隙小,相导线之间的间隙小,若通道环境较为恶劣,尤其是易引发导线不同期摆动的区段,则跳闸率和停运率明显上升。针对500 kV紧凑型输电线路在运行中出现的不同类型跳闸故障,从塔型结构及线路的设计、运行和反措的角度分析总结,以期达到少跳闸、少停电的目的。It is pointed out that the air gap between conductor and tower window of 500 kV compact transmission line is small as well as the gap between phase conductors. If the channel environment is rather bad, especially in the section where asynchronous swing usually occurs, the trip rate and outage rate will be obviously higher. According to different types of tripping faults in 500 kV compact transmission lines, the design of tower structures, the operation of transmission lines and countermeasure are analyzed and summarized so as to achieve the goal of less tripping and less power failure.
