摘　　要：采用三维有限元场-路耦合方法和磁路方法研究饱和铁芯型超导限流器(SFCL)的瞬态过程,并针对故障状态时,直流超导线圈感应高电压现象,提出使用短路线圈改善超导线圈的高压问题。通过与限流器样机的试验结果对比分析,证明数值计算方法的正确性。In this paper, the transient performance of a magnetic core fault current limiter （FCL） saturated by high temperature supeconducting （HTS） DC bias winding is investigated by using both 3 -dimensional （3D） field -circuit coupled simulation and magnetic circuit analysis. A high voltage is induced on the DC HTS winding during the fault current state. The induced voltage is computed and a short circuit coil for the reduction of induced voltage is studied. The numerical computations are verified by the experiment results on an FCL protorte.
