介绍了交流损耗测量理论,搭建了高温超导带材的电测法测量平台,并分别测量不同频率下AMSC和Super Power两家公司生产的YBCO带材的交流损耗。将测试结果进行了归一化处理,并与计算结果和Norris模型进行比较,从两种带材材料层面分析了测量结果与计算结果存在微小差别的原因。实验结果表明测量结果与计算结果基本一致,并且和Norris模型吻合较好,说明该测量系统可以很好地测量不同频率下YBCO带材的交流损耗。
The theory of AC loss measurement is introduced and the measuring platform of the electric measuring method for high temperature superconducting tapes is set up. The AC loss of YBCO tape produced by AMSC and Super Power at different frequencies is measured respectively. The test results were normalized and compared with the calculated results and the Norris model. The reasons for the slight differences between the measured and the calculated results were analyzed from the two strip material levels. The experimental results show that the measurement results are in good agreement with the calculated results and agree well with the Norris model, which shows that the measurement system can measure the AC loss of YBCO strip at different frequencies well.
