摘　　要：介绍了35kV/90MVA饱和铁心型超导限流器中超导直流励磁磁体的仿真、设计、制作及相关实验,该磁体使用了17.6km超导带材,额定安匝数为141000安匝。利用磁场仿真计算获得磁场分布,并根据磁场分布及超导带材磁场下Ic的衰减特性,采用多饼串并联结合的方法优化磁体设计,既降低了磁体中的感应电压,保证了磁体的励磁能力,增强了磁体的稳定性,又节约了材料与成本。通流实验和磁场测量检验了设计方法的正确性,证实了磁体通流能力满足设计要求。A superconductive magnet with 141 000 ampere-turns designed magnetizing power, made of 17600 meters of BSCCO 2223 HTS tapes, was fabricated and tested. This coil was built for a 35 kV/90 MVA saturated iron-core fault current limiter. Computer simulations on the performance of the coil were carried out using ANSYS. The critical current of the superconducting coil and the DC resistance of the coil, including the non-superconducting joints, were investigated. Spatial distribution of the magnetic field was measured and compared with the simulation results. In this paper, we will report the configuration and the key parameters of the coil as well as the experimental and simulation results.
