摘要
根据一个牵引变压器的损耗,提出了谐波对绕组电阻的影响。对同心式和饼式线圈的变压器进行了分析。使用二维有限元计算软件“Flux2D”进行了多种仿真,并且将其结果与实际变压器测量值进行对比,提出一个简单的定律,由此可确定2种不同类型变压器电阻随频率的变化规律。
This paper presents the influence of harmonics on the windings’resistance, corresponding to the losses of a tractiontransformer. Concentric and pancake windings transformers have been analyzed. Various simulations with the 2D finite elements program“Flux2D” have been performed and compared to measurements done on real transformers. A simple law is proposed, it allows determining thevariation of the resistance with the frequency for each transformer type.
