摘　　要：针对当前自动跟踪补偿消弧线圈存在的问题,提出了解决由调节可控硅导通角而产生高次谐波的新方法-基于变耦电抗法的三相五柱式消弧线圈.该方法利用改变互感器的耦合系数来调节电感.文章给出了变耦电抗器的消弧线圈硬件实现方式和调谐原理,实验显示该消弧线圈调节快速,无高次谐波,能精确地自动跟踪补偿电网电容电流.By analyzing the defect of automatic resonance arc suppression coil, a novel arc suppression coil with three phases and five columns is presented to solve the high-order harmonic induced by regulating the triggering angle of Thyristor-Controlled Reactor （TCR）, which is based on changing magnetic coupling to adjust inductance. That means can adjust inductance by altering the mutual inductance coupling quotiety. The hardware realization and the turning principle of the arc suppression coil are also presented. The results show that this type of arc suppression has quick atic resonance speed, no high order harmonic, accurate tracing and compensating capacitive current automatically.
