高温超导(HTS)带材的基带可以改变带材的磁场分布,从而影响到带材的交流损耗。从实验和数值分析两个角度计算了不同高温超导带材的自场损耗,并分析了不同基带对带材自场损耗的影响。利用不同高温超导带材制作了多个单层高温超导电缆模型,并从磁性基带的角度分析了各模型的交流损耗特性。结果显示非磁性基带不影响带材的交流损耗。对于超导电缆模型而言,当磁性基带位于模型外侧时,模型外部空间不存在损耗磁通。此外BSCCO模型和YBCO模型的交流损耗特性相似,NY模型和YN模型的损耗相比前两个模型偏大。尤其在低电流区域,YN模型的交流损耗最大。 The base band of a HTS tape can change the magnetic field distribution of the tape and thus affect the AC loss of the tape. The self-field loss of different high-temperature superconducting tapes was calculated from two aspects of experiment and numerical analysis. The influence of different base tapes on self-field loss of tapes was analyzed. A number of single-layer high-temperature superconducting cable models were fabricated using different HTS tapes. The AC loss characteristics of each model were analyzed from the perspective of magnetic baseband. The results show that the non-magnetic tape does not affect the AC loss of the tape. For the superconducting cable model, there is no loss flux in the outer space of the model when the magnetic base tape is outside the model. In addition, the exchange loss characteristics of BSCCO model and YBCO model are similar, and the losses of NY model and YN model are larger than those of the first two models. Especially in the low current region, YN model has the largest AC loss.
