摘要
交流损耗是高温超导YBCO线圈设计的一个重要参数,直接关系到高温超导装置的运行成本和稳定性。文中利用热测法实现对高温超导YBCO线圈交流损耗的准确测量,并给出了高温超导YBCO线圈的理论数值计算模型,通过理论计算值与实验结果的比较分析,两者结果基本相符。研究结果为开展1MJ高温超导储能-限流磁体的研制具有十分重要的指导意义。
AC losses of YBCO high temperature superconductor( HTS) coils are an important parameter for coils design,which have the direct affects on the stability and running cost of HTS apparatus. In order to realize a quick and accurate measurement of AC losses for YBCO HTS coils,the calorimetric measurement method of AC losses was systematically investigated in this paper. A numerical model to calculate AC losses of YBCO HTS coils was proposed. The theoretical calculated result and the experimental data were compared and analyzed. It showed that the calculated values were in agreement with measured results quite well. The research results can be very important instructive in the development of magnet designing for 1MJ SMES-FCL.
