摘　　要：介绍了三相五柱式消弧线圈的补偿原理。该消弧线圈在结构上突破了传统消弧线圈的模式 ,将传统的接地变压器和消弧线圈有机地结合成一个整体 ,通过可控硅调节副边电感电流的方法 。The compensation principle of arc suppression coil with three phases and five columns system is introduced in this paper. The structure of this arc suppression coil is different from the traditional model, and it is the integration of the traditional grounding transformer and arc suppression coil. The arc suppression coil with three phases and five columns system can realize automatic trace and compensation for grounded fault capacitive current of power network by the method of regulating inductive current of second winding with silicon controlled rectifier.
