摘　　要：聚变装置上低温超导磁体的管内电缆导体(Cable-in-Conduit Conductor,CICC)运行在大电流和快速变化磁场环境中,导体的合理设计是其能否稳定运行的关键。由于工程上CICC导体的设计是一个多次尝试和优化的过程,为此提出了基于稳定性和损耗机理的导体设计思想;推导了关于CICC导体结构参数矩阵方程;建立了导体数值仿真的基本设计模型。同时进行了导体的模拟设计,并将仿真设计结构与工程设计情况进行了比较和分析,结果证明二者吻合的较好。CICC, i.e. Cable - in - Conduit Conductor, as the conductor for large cryogenic superconducting magnets in fusion device, operates under the condition of high current and rapid changing magnetic field. It is a key to rationally design the conductor for steady operating. However, it is a try and optimization process to design CICC in engineering. So, the thought for the simulation design was put forward based on stability and losses, the equation of design for CICC configuration was deduced, and the model of the simulation was built. The simulation output was compared with that of engineering design, and the comparing result was encouraged.
