摘要
管内电缆导体(cable-in-conduit conductor,CICC)是目前为止大型低温超导磁体的首选导体,CICC在超导储能磁体及大型超导核聚变实验装置中的应用具有不可比拟的优越性。CICC的稳定性对其实际应用起着重要影响,因此开展关于CICC稳定性的研究对于推广CICC的应用有着重要的实际意义。利用一维数学模型(Gandalf软件)对ITER校正线圈(CC)CICC的稳定性进行仿真,研究了运行电流、运行磁场和He质量流速率对CICC的稳定性裕度影响;同时,将基于热平衡方程的理论结果和仿真实验结果进行比较,验证了理论的可靠性和软件的实用性。
The cable - in - conduit conductor（CICC） is the preferred conductor of large superconducting magnet. The applica- tion of CICC in a large superconducting nuclear fusion experimental device and superconducting energy storage magnets has incomparable superiority. CICC stability plays an important impact on its practical application, therefore, research on CICC stability has important significance for promotion of CICC application. In this paper, one -dimensional mathematical model （Gandalf software） was used for the stability simulation of ITER correction coil（CC） CICC to study the effectof the operating current, operating magnetic field and the He mass flow rate on CICC stability margin. Meanwhile, the results of theoretical calculations based on the heat balance equation were compared to simulation results to verify the reliability of theory and the usefulness of the software.
