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SS_(7C)型电力机车原有2路列车供电的基础上再增加一路400 k W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。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.

关 键 词：SS7C型电力机车 逆变柜 列车供电系统 备份
