摘　　要：针对35 kV/1.0 kA单相冷绝缘高温超导电缆及以液氮为低温冷却介质的单通道循环冷却系统,研究超导电缆轴向和径向温度分布。根据冷绝缘高温超导电缆的结构特点,计算了超导电缆的热负荷,建立了超导电缆热分析数学模型和热平衡方程。通过求解热平衡方程,得到了稳态运行时超导电缆的轴向和径向温度分布,为超导电缆低温系统的设计与优化提供了重要的参考价值。In this paper,the temperature distribution of 35 kV/1.0 kA cold-dielectric single-phase high temperature superconducting （HTS） power cable with single liquid nitrogen cooling channel was investigated.According to the structural characteristics of the HTS power cable,the thermal load of the superconducting cable was calculated,and then the heat balance equations were established based on the thermal analysis model of the cable.Based on the heat balance equations,the longitudinal temperature distribution and the radial temperature distribution of the cable under steady-state conditions were obtained,which could provide an important reference value for the design and optimization of the cryogenic system of HTS power cable.
