Abstract

REBCO stacked cables have great potential for application in high-temperature superconducting (HTS) power devices due to their compact structure and easy scalability. However, when the cable runs in an alternating external field, it will generate AC losses, and excessive AC losses will increase the cooling cost and even cause the cable quench. This article proposes a magnetic material wrapped REBCO cable that can effectively reduce the AC loss of the cable under external magnetic fields. Firstly, the AC losses of REBCO cables wrapped with magnetic and non-magnetic materials were compared under different strength external fields. The results showed that cables wrapped with strong magnetic materials had lower AC losses. Secondly, the AC losses of cables prepared with strong magnetic wrapping materials of different thicknesses were studied under different external fields. The results showed that the thicker the magnetic material, the more significant the reduction in AC losses of the cable. Overall, this article presents new analysis and results that are useful for future design of HTS cables.

用磁条包裹的叠层 REBCO 电缆交流损耗研究

REBCO 叠层电缆结构紧凑，易于扩展，因此在高温超导（HTS）功率器件中具有巨大的应用潜力。然而，当电缆在交变外场中运行时，会产生交流损耗，过高的交流损耗会增加冷却成本，甚至导致电缆熄火。本文提出了一种磁性材料包裹的 REBCO 电缆，可有效降低电缆在外加磁场下的交流损耗。首先，比较了在不同强度的外磁场下，用磁性材料和非磁性材料包裹的 REBCO 电缆的交流损耗。结果表明，用强磁性材料包裹的电缆交流损耗较低。其次，研究了使用不同厚度的强磁包裹材料制备的电缆在不同外场条件下的交流损耗。结果表明，磁性材料越厚，电缆交流损耗的降低越明显。总之，本文提出的新分析和结果对未来 HTS 电缆的设计很有帮助。
