200km/h动力分散型电动车组辅助电源改进的探讨

Discussion on improving the auxiliary power supply for 200 km/h power-distributed EMUs

对我国最近试制成功的 2 0 0 km / h动力分散型电动车组辅助电源负载进行了分析与评论 ,建议取消辅助变流器 ,包括空调器在内的辅助电动机采用单相电动机 ,直接从主变压器辅助绕组取电 ;110 V直流电源也是经整流器得到。这样 ,既可以降低成本 ,又可以减轻电动车组重量。

The load of auxiliary power supply for the newly developed 200 km/h EMUs in China is analyzed and reviewed. It is proposed to get rid of the auxiliary converter and to replace the motors including those inside air conditioners with single phase motors . The supply is taken directly from secondary windings of the main transformer. This is also the case for 110 V DC supply, obtained after rectified. By doing so, both costs and EMUs weight are cut down.
