摘要
2007年4月1日,因雷击造成商丘区域铁路牵引站的两条110kV同塔双回输电线路同时跳闸,牵引站失压7min,针对该次事件,河南商丘供电公司从解决同塔双回线路雷击同时跳闸和保障牵引站的供电可靠性方面,进行了充分调研、论证,采取将外串联(纯)间隙(金属氧化物)线路避雷器安装在输电线路的易击段作为防雷措施,结果表明:近年来,已安装外串联(纯)间隙(金属氧化物)线路避雷器的杆塔未发生雷击跳闸。
On April 1, 2007, caused by lightning, two 110kV same tower double-circuit transmission lines in Shangqiu regional railway traction power station tripped at the same time, traction station lost voltage for 7min, according to this event, the Henan Shangqiu power supply company carried out a full investigation and argument from the aspects of solving double circuit line on the same tower lightning stroke tripping at the same time and guarantee the traction station power supply reliability, it is adopted that installing the external series gap （ pure ） （ metal oxide ） line surge arrester on transmission line at vulnerable part as lightning protection measures, the results showed that; in recent years, no lightning trip has occured on the tower with the external series gap （ pure ） （ metal oxide ） line surge arrester.
