三相五柱式消弧线圈及其补偿原理

The Arc-suppression Coil with Three Phases and Five Columns and Its Compensation Principle

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。三相五柱式消弧线圈通过 可控硅调节副边电感电流的方法，实现了对电网对地电容电流的自动跟踪补偿。

The compensation principle of arc-suppression coil with three phases and five columns is introduced in this paper The structure of this arc-suppression coil is different from that of traditional model. It is the integration of the traditional grounding transformer and arc-suppression coil. The arcsuppression coil with three phases and five columns can realize automatic trace and compensation for grounded-fault capacitive current of power system by the method of silicon controlled rectifying inductive current of second winding.
