摘要
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。
AC loss measuring theory was introduced and an AC loss measurement system of YBCO was proposed. AC losses of YBCO tapes from AMSC and superpower were measured in different frequencies. Normalized results were compared with calcu- lation results and Norris model. The reasons why there was a slight difference between the measurement results and calculation re- suits were analyzed in the material level. Measurement results and calculation results were basically identical. The results were in good agreement with Norris model. The results prove that the proposed measurement system is justified in measuring AC loss of YBCO tapes in different frequency.
