摘　　要：提出了基于信号注入法的可控硅投切电容式消弧线圈设计方案。采用从消弧线圈的副边向电网注入变频电流信号,测量系统电容电流,利用可控硅投切电容实现自动调谐的方法。实际现场运行表明,该型消弧线圈具有调节速度快,补偿精度高,无谐波危害,且无机械动作可靠性高等特点。A design of arc suppression coil with thyristor series capacitors based on injecting current is provided.By injecting currents with various frequencies into power net from the secondary side of arc suppression coil and calculating the capacitive current ,the automatic resonance adjustment is realized with the thyristor series capacitors.The results of field running show that it has quick adjustment speed,accurate compensation,preferable reliability and no harmonic pollution.
