摘　　要：本文构建了一个适用于大容量短轴型和长轴型高温超导电机的制冷系统,所设计的制冷系统的结构特点在于不再需要传输低温制冷工质的旋转结构。首先,对所设计的低温制冷系统进行热负荷的有限元仿真分析;通过有限元仿真分析发现,在去掉旋转结构之后,可以降低制冷系统的热负荷,达到提高制冷效率的目的;最后,对这种大容量短轴型和长轴型高温超导电机的电磁特性进行了对比分析。In this paper,a cryogenic system suitable for large capacity high temperature superconducting(HTS)motor with short axis and long axis is designed.The characteristic of the proposed cryogenic system is that the rotary joint translating the refrigerant is no longer needed.Firstly,the heat load of the system is simulated with FEM method.From the simulation results it can be found that the system heat load is reduced and the cooling efficiency is improved.Finally,the electromagnetic characteristics of the two topologies are contrastive analyzed.
