200km/h动力分散型电动车组主变压器辅助绕组电压的选定

The determination of voltage for auxiliary winding of traction transformer used on 200 km/h power distributed EMUs

针对我国用于客运专线的 2 0 0 km / h动力分散型电动车组 ,通过对网压波动的讨论和主变压器辅助绕组电压与电流的计算 ,说明了主变压器辅助绕组电压选择 790 V的理由。

By discussion on line voltage variation and through calculation for voltage and current of auxiliar winding of the main transformer for the 200 km/h power distibuted EMUs for passenger line in China, the reason for choosing 790 V as the auxiliary winding voltage of main transformer is explained.
