摘　　要：1台瓦斯断电仪只能切断一种电压的移动变电站,但在2台不同电压等级的移动变电站上,就无法直接切断2台移动变电站电源,针对以上问题,利用加装中间继电器实现同时切断2台移动变电站电源。The gas can only be broken off for a voltage mobile substation, but in two different models of mobile substation, will not be able to directly cut off the two mobile power substation, the paper against the above - mentioned problems, the use of retro- fitting of the problem among relay be resolved.

关 键 词：瓦斯断电仪 移动变电站 电源
