摘　　要：以螺旋电流导体磁场分析为基础 ,推导了超导输电电缆各层导体自感和层间互感 ,以及各层导体所承受的不同方向的磁场强度计算公式 ,并给出算例 ,这些计算方法是优化超导电缆层间分流均匀性 ,分析超导电缆交流损耗的基础 .Based on the analytical field calculation of helical coils, the self-inductance of cable layers and mutual inductance between layers were analyzed. The analytical field calculation of HTS tape in cable superconductor layers suffered from the axial magnetic field and azimuthal magnetic field were discussed. A practical sample of HTS cable was chosen to calculate its magnetic field parameters. This work was the foundation of optimizing the transport current distributed uniformly in conductor of HTS cable with the same or variable tape-winding pitches and analyzing AC losses of HTS cable.
