摘要 随着高温超导YBCO带材载流能力的不断提高和成本的逐渐降低,YBCO线圈及磁体的应用将日益广泛。文中利用有限元方法研究了YBCO线圈的交流损耗特性,计算了50Hz下线圈的瞬时交流损耗,分析了每匝带材中的电流和磁场分布。仿真结果表明,线圈内侧承受的磁场最大,但线圈中部每周期的交流损耗最大,且线圈中始终存在未被磁场穿透的区域。除此之外,文中实验测量了YBCO线圈的临界电流和交流损耗,实验结果良好地验证了仿真方法的正确性。 With the increasing of current carrying capacity and decreasing of production cost of YBCO tapes, the application of YBCO coils and magnets will become more and more widely. In this paper, the AC loss characteristics were studied based on FEM method. The instantaneous AC losses were calculated and the current and magnetic field distribution were analyzed. The simulation results showed that the innermost turn of the coil withstood the maximum magnetic field, but the maximum loss per cycle appeared in the middle of the coil, and there is always a region where magnetic flux can't penetrate. In addition, we measured the critical current and AC loss of the coil and the experimental results validated our simulation method.
