The invention discloses a tramcar line power supply system, which is characterized in that when a certain charging unit fails, a third change-over switch is controlled to be closed, so that a downlinkcharging unit provides electric energy for charging rails of a downlink charging unit and an uplink charging unit at the same time; or the uplink charging unit provides electric energy for the charging rails of the uplink charging unit and the downlink charging unit at the same time, so that the uplink charging unit and the downlink charging unit of the station can keep normal charging work; whena certain bus fails or only one bus is normal, the first change-over switch, the second change-over switch and the third change-over switch can be controlled to be switched on according to conditionsto ensure that the uplink charging units and the downlink charging units of all stations on the whole line keep normal charging work. The problem that electric energy cannot be supplemented to the energy storage unit in time when a certain bus or a certain charging unit breaks down is solved, and the stability and reliability of power supply and charging of the whole circuit are greatly improved.
本发明公开了一种有轨电车线路供电系统,在某个充电单元故障时,控制第三切换开关闭合,使下行充电单元同时为下行充电单元和上行充电单元的充电轨提供电能,或上行充电单元同时为上行充电单元和下行充电单元的充电轨提供电能,从而使该站点的上行充电单元与下行充电单元能够保持正常充电工作;当某条母线故障时或仅剩一条母线正常时,均可以根据情况通过控制第一切换开关、第二切换开关以及第三切换开关的闭合来保证整条线路上所有站点的上行充电单元和下行充电单元保持正常充电工作,避免了某条母线或某个充电单元故障时无法为储能单元及时补充电能的问题,大大提高了整条线路供电和充电的稳定可靠性。
