电力机车用高温超导变压器电流引线导热路径延伸方法的研究

按照车用高温超导变压器对电流引线的要求,以有限元体传热学为分析基础,对电流引线进行了传热计算,给出了初步设计方案。针对车载变压器的有限空间,提出了通过将引线绕制成螺线管状的方法来解决引线的导热路径长度较长与空间可用高度不够的矛盾,并通过热损耗分析得出下端绕制方式优于上端绕制方式的结论。

Research for the Method to Extend Thermal Path of Current Leads for HTS Transformer Used on Electrical Locomotive

This paper describes the draft designs of current leads for high temperature superconductor transformer (HTS transformer), according to the requirements of HTS transformer, and shows the results of a heat load evaluation of current leads for HTS transformer used on electrical locomotive, founded on FEI theory. To deal with the problem that space in the transformer is not long enough for the current leads, parts of the current leads wind into the shape of solenoid.
