摘要
分析了当前自动跟踪补偿消弧线圈的发展和存在的问题,并提出了解决由调节可控硅导通角带来的高次谐波的新方法——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,并分析了其谐波特性和动态特性,实验显示该消弧线圈调节特性好,谐波分量少,能实现电抗值的柔性调节并能精确地自动跟踪补偿电网电容电流。
By analyzing the current state and existing problems of automatic resonance arc suppression coil, a novel arc suppression coil with three phases and five columns based on the changing magnetic coupling is proposed to mitigate the high-order harmonics produced by regulating the triggering angle of thyristor-controlled reactor （TCR）. The inductance of arc suppression coil is adjusted by altering the mutual inductance coupling quotiety. The volt ampere characteristic of the arc suppression coiI and its harmonic behavior are also analyzed. Experiments show that this type of arc suppression coil has a fast resonance speed, a bit of harmonic components. It can adjust flexibly the inductance, trace accurately and compensate automatically the capacitive current in network.
