The invention discloses a control circuit for subway vehicle train activation. The control circuit comprises an auxiliary emergency starting switch, an auxiliary power supply system, a control negative wire, a non-permanent bus positive wire, a permanent bus positive wire, a storage battery box, a non-permanent bus negative wire and a train activation relay. The storage battery box comprises a non-permanent bus control contactor, a storage battery under-voltage relay and a storage battery; the circuit is characterized in that a main contact of the non-permanent bus control contactor is arranged between the auxiliary power supply system and the storage battery; and an auxiliary contact of the auxiliary emergency starting switch is connected between a non-permanent bus control contactor coiland a storage battery under-voltage relay contact. Therefore, the trouble that a train loses a direct current control power supply when the non-permanent bus control contactor breaks down is solved,and the reliability of the main line operation of the train is improved.

    一种地铁车辆列车激活的控制电路,包括辅助应急启动开关、辅助电源系统及控制负线、非永久母线正线、永久母线正线、蓄电池箱、非永久母线负线、列车激活继电器,蓄电池箱包括非永久母线控制接触器、蓄电池欠压继电器、蓄电池,其特征在于:非永久母线控制接触器的主触点设置在辅助电源系统与蓄电池中间,并且辅助应急启动开关的辅助触点连接到非永久母线控制接触器线圈和蓄电池欠压继电器触点之间,本发明解决了非永久母线控制接触器发生故障时列车失去直流控制电源的困扰,提高了车辆正线运营的可靠性。
