摘　　要：针对调匝式消弧线圈现有的调谐方法测量准确度差、不能适应在牵手变电站中并联运行的问题,提出了利用谐振法结合曲线拟合法来调谐测量系统电容电流的新方法。新方法测量准确度高,调挡数目少,能自动并联,无需相互通信,适合在各种场合并联运行。模拟电网试验和现场运行试验结果令人满意。In view of some problems on forthcoming tuning method, such as low accuracy in measurement and not adapting to parallel operation in ring distribution system, this paper proposes a new tuning method for multi-tap arc-suppression coils, i,e, resonance method coupling curve-fitting. Adopting the new method, high accuracy in measurement is acquired and parallel operation of arc-suppression coils in ring distribution system is easy to achieve, which need no communication from each other, The experiment and operation results are satisfied.
