摘要
C ICC超导体是大型低温超导磁体的首选导体,它运行在大电流和磁场快速变化的环境中,磁通进出超导体以及外界磁场的变化会产生交流损耗,而交流损耗对C ICC超导体稳定性运行有很大的影响,这样开展C ICC超导体交流损耗的研究就显得非常重要。因此,文中针对C ICC导体运行条件和几何结构,提出交流损耗数字模拟的想法,并将数字模拟结果与工程计算值进行了比较和分析,二者基本吻合。
CICC has been the first selected conductor for large cryogenic superconducting magnets. With high current, rapid changing magnetic field, It can produce AC Losses when magnetic field changes and flux passes in and out the conductor. However, the AC Losses will impact the stability of CICC. It is very vital to study the CICC AC Losses. So in this paper, a try for the numerical simulation is put forward aiming the conductor configuration and operating condition. The simulation result was compared with engineering calculation. The comparing results are encouraged.
