电力机车主变压器设计中的若干问题

Some issues in designing main transformer of electric locomotive

根据电力机车运行特点,概述了机车主变压器与电力变压器设计上的不同之处,包括变压器形式,铁心、绕组的型式及选取原则,阻抗电压的选取原则。

Some differences in designing the main transformer of electric locomotive and general transformer are summarized, based on the operating characteristic of electric locomotive. There are some issues which should be considered. They are the type of transformer, iron core, the type of winding and its selection principle, the selection principle of impedance voltage, the caculation of losses and temperature rise.
