摘要
强油循环风冷在220kV变电站主变中有着广泛的应用,其冷却器全停跳闸回路是重要的二次回路之一。本文通过对强油循环风冷全停跳闸回路现状分析,对其存在的问题提出对应的建议。
Forced-oil circulated air-cooler has been used widely in the 220kV＇ s main transformer, the completed shutdown tripping circuit of the cooler is the important one in the secondary circuit. The articles attends to analysis the completed shutdown tripping circuit in the forced-oil circulated air-cooler and make corresponding suggestions for the existing problems.
