摘要
传统蓄电池电力工程车需要辅助逆变器提供三相交流电源供给辅助负载,同时需要牵引蓄电池充电机向牵引蓄电池充电。文章介绍了一种集成式辅助变流系统,该系统不仅包括辅助逆变器和牵引蓄电池充电机的功能,还具有电路结构简单、安装体积小、成本低、维护方便等特点。该辅助变流系统的设计为实现蓄电池电力工程车平台化设计起到关键作用。
Auxiliary inverter is necessary for traditional battery electric locomotive to provide three-phase alternating current for auxiliary loads. Meanwhile,charger is needed for traction battery to charge. This paper presents a kind of integrated auxiliary converter system which not only including the functions of auxiliary inverter and traction battery charger,but also having many advantages such as simple structure,small installation space,low cost and convenient maintenance. The design of auxiliary converter system makes the key point in the platform design of battery electric locomotive.
