摘要/Abstract

摘要： 分析了大功率中频变压器绕组高频损耗与铁心高频损耗的解析计算方法,建立了其优化设计流程。采用自由参数扫描法,对一台面向电力机车轻量化应用的300 kW中频变压器进行了优化设计。通过建立评价系数公式,最优方案兼顾了变压器的损耗与重量。利用电磁有限元仿真计算软件Ansoft Maxwell,分别在二维涡流场与瞬态场中,对其中6组设计方案的绕组损耗与铁心损耗进行了仿真验证。对比解析设计与有限元仿真计算结果,两者误差在可接受范围内,验证了优化设计方法的正确性与有效性。

Abstract: The analytical calculation method for winding loss and core loss of high power medium frequency transformer was analyzed, and the optimal design process was established. A 300 kW medium frequency transformer for lightweight application of electric locomotive was designed optimally by the method of free parameters scanning. Through the establishment of evaluation parameters equation, the best scheme considered both the total loss and transformer weight. On this basis, the winding loss and core loss for six groups of design scheme were verified by finite element simulation in 2D eddy current field and transient field of Ansoft Maxwell respectively. Through the results comparison of analytical design and finite element simulation, the error is acceptable, which verifies the correctness and effectiveness of the optimal design method.

Key words: high power medium frequency transformer, optimal design, lightweight, high frequency loss, finite element simulation
