摘要
通过建立高温超导电缆等效电路模型,并提出电流分布等效数学方程,求得高温超导电缆导体层电流分布。绕制一根0.2m长110kV/2kA高温超导电缆样缆,并进行载流能力实验,得到各层电流分布结果。分析发现,各层电流分布的实验结果与理论计算结果吻合,从而验证电流分布计算模型的正确性,以及调整绕制角度对均匀层间分流的有效性。研究结论对以后更长高温超导电缆的载流能力分析具有一定的指导意义。
To obtain the current distribution of High Temperature Superconducting （HTS）cable,the equivalent circuit model of HTS cable was established and the current distribution numerical equations were given.A 0.2m 110kV/2kV sample of HTS cable was winded and the current-carrying capacity experiment was carried out.It is found that the experimental results of current distribution agree with the theoretical calculation results well.The correctness of the equivalent circuit model was verified so as to adjust the winding angle to obtain a uniform current distributionin conductor layers.The study is significant for the analysis of a long HTS cables current-carrying capacity.
