摘　　要：该文设计一种带有三次绕组的自耦变压器结构矿用消弧线圈,二次绕组接晶闸管投切电容电路,第三绕组具有高短路阻抗特性,输出端接反并联晶闸管,对消弧线圈进行细调。通过系统双调节回路的协调控制,可实现变压器消弧线圈的大范围连续调节。对消弧线圈的运行参数、控制策略以及调谐方法进行深入的研究分析。这种消弧线圈具有响应速度快、连续调节范围宽、谐波小、伏安特性好及补偿精度高等优点。MATLAB仿真验证新型矿用消弧线圈的合理性和优越性。In this paper,an autotransformer structure mine arc-suppression coil with a tertiary winding is designed.The secondary winding is connected to a thyristor switched capacitor(TSC)circuit,the third winding has high short-circuit impedance characteristics,and the output terminal is connected to an anti-parallel thyristor to finely adjust the arc-suppression coil.Through the coordinated control of the dual regulation loops of the system,large-scale continuous regulation of the transformer arc suppression coil can be realized.The operating parameters,control strategies and tuning methods of arc suppression coils are deeply studied and analyzed.This arc-suppression coil has the advantages of fast response speed,wide continuous adjustment range,small harmonics,good volt-ampere characteristics and high compensation accuracy.MATLAB simulation verified the rationality and superiority of the new mining arc suppression coil.
