摘要

为了提高电力机车DC 600 V 列车供电系统的可靠性，提出在SS7C 型电力机车原有2 路列车供电的基础上再增加一路400 kW的供电电路，对原有列车供电形成冷备份，同时增加逆变柜，与机车原有劈相机形成冗余。运行考核表明改进后的列车供电系统可靠性有所提高。

Abstract

To improve the reliability of locomotive DC 600 V train power supply system, the scheme of adding one 400 kW power supply circuit based on the existed two power supply circuit for backup was presented, as well as adding a inverter cabinet for backup of the phase splitter, which was validated improved the reliability of the train power supply system greatly by operation test.
