对于使用高温/超导/超导（HTS）带材的大功率应用，应使用平行面对面堆叠带状导体，因为单根带子在所需大电流的流动方面受到限制，并且堆叠带状导体中的带子之间需要适当的距离以实现高压绝缘。由于屏蔽效应，堆叠带导体与单带导体相比具有不同的特性。一般情况下，高温超导带材以线圈形状缠绕使用，因此，线圈中产生的磁场作为外部场，并且对线圈中的每个带材具有不同的方向。本文研究了叠带导体在不同方向的外部磁场下的磁化损耗，并将叠带与单带的测量结果进行了比较，并通过与非绝缘叠带的测量结果比较，提出了叠带导体中带间绝缘厚度的影响。我们通过有限元方法求解堆叠带状导体的磁化损耗来检验实验结果。
For large power application using high-T/sub c/ superconducting (HTS) tape, parallel face-to-face stacked tape conductor should to be used because single tape is limited in flowing of demanded large current, also, appropriate distance between tapes in stacked tape conductor is needed for high voltage insulation. The stacked tape conductor has different characteristics compared with single tape because of screening effect. In general situation, HTS tapes are used by winding in coil shape, so, magnetic fields generated in the coil are operated as external fields and have various direction to each tape in the coil. In this paper, we research the magnetization loss in stacked tape conductor exposed to external magnetic fields having various direction and compare measured results of stacked tape with those of single tape, and we also present influences of insulation thickness between tapes in stacked tape conductor by comparison to the measured results for noninsulation stacked tape. We solve the magnetization loss in stacked tape conductor by finite element method to examine the experimental results.
