我们报告了铁芯中堆叠高温超导带材的交流损耗特性。为了估计损耗分布，我们使用量热法测量了每个堆叠的高温超导带。为了阐明铁芯的影响，我们测量了没有铁芯的堆叠高温超导带材的交流损耗。位于铁芯中的堆叠式高温超导带的交流传输电流损耗大于没有铁芯的堆叠式高温超导带的交流传输电流损耗。漏磁场引起的磁化损耗的分布是HTS带外侧的损耗最高，因为屏蔽电流阻止磁场渗透到堆叠的HTS带的内部。
We report the ac loss characteristics of stacked HTS tapes in an iron core. To estimate the loss distribution, we measured each stacked HTS tape using a calorimetric method. To clarify the influence of an iron core, we measured the ac losses of the stacked HTS tapes without the iron core. The ac transport current losses of the stacked HTS tapes positioned in the iron core were greater than those without the iron core. The distribution of the magnetization losses by the leakage magnetic field was that the loss at the outside of the HTS tape was highest because shielding current prevented the magnetic field from penetrating to the inside of the stacked HTS tapes.
