摘　　要：管内电缆导体(cable-in-conduit conductor,CICC)即铠装电缆导体,是由内冷超导体(ICS)发展演变而来的。随着超导技术的发展,CICC在大型超导核聚变实验装置及超导储能磁体中的应用具有不可比拟的优越性。CICC通常运行在大电流和快变磁场中,它的稳定性对其实际应用起着重要影响,因此对CICC稳定性研究有很大的实际意义。文中基于一维数学模型(Gandalf软件)的基础上,对ITER校正线圈(CC)CICC的稳定性进行仿真,研究了CICC的稳定性裕度与电缆的运行温度、加热长度和质量流速率之间的关系,根据仿真结果,得出了电缆运行温度、加热长度与氦的质量流速率对CICC稳定性裕度的影响,最后把仿真结果与理论分析进行对比,验证了仿真结果的正确性。The cable- in- conduit conductor（ CICC） is the conductor called armored cable conductor which is the evolution of the Internal Cooling Superconductor（ ICS）. With the development of superconducting technology,CICC used in large superconducting nuclear fusion experimental device and superconducting magnetic energy storage has incomparable superiority. CICC usually runs at large currents and fast changing magnetic field,its stability plays an important influence on its practical application,so the research of the stability of CICC has great practical significance. In this paper,one- dimensional mathematical model（ Gandalf software） was used for ITER correction coil（ CC） CICC stability simulation to study the relationship between the CICC stability margin and operating temperature,heating cable length and the He mass flow rate. Meanwhile,according to the simulation results the influence of the operating temperature,heating cable length and the He mass flow rate on the CICC stability margin was obtained. Finally,we compared the simulation results with the theoretical analysis to validate the correctness of the simulation results.
