| 摘 要： | 针对冷绝缘高温超导电缆(Cold Dielectric High Temperature Superconducting cable,CD HTS cable)在不同载流下的运行稳定性,采用有限元数值分析方法对超导电缆内部温度场进行准确计算和分析。根据超导电缆内部各层传热特征,建立基于ANSYS的CD HTS电缆有限元模型,给出正常载流及故障载流下超导电缆温度场分析传热边界条件,计算得到不同载流情况下超导电缆本体温度分布变化规律,从而为其通流能力影响下的运行稳定性分析提供参考依据,对超导电缆的故障保护具有一定的指导意义。

| Abstract: | To analyze the operation stability of Cold Dielectric High Temperature Superconducting(CD HTS) cable with different current carrying capacity,a finite element numerical analysis method was used to calculate and analyze the temperature field of the CD HTS cable accurately.According to the thermal transmission properties of the CD HTS cable's layers,the finite element analysis model of the HTS cable was established based on the ANSYS software and the thermal boundary conditions were given considering the normal and fault current carrying.So the temperature distribution and the variation in HTS cable based on different current load were obtained.These results can be used for the analysis of HTS cable operation stability and is significant for the protection of the superconducting cable. |
