地铁车辆辅助供电扩展系统
摘要：
本发明提供一种地铁车辆辅助供电扩展系统，包括：主电路、控制电路、第一断路器、第二断路器和第一接触器，第一接触器通电时处于闭合位，第一接触器断电时处于非闭合位；主电路包括第一电路与第二电路，第一接触器连接第一电路与第二电路；第一电路通过第一断路器与控制电路连接，第二电路通过第二断路器与控制电路连接；第一电路的通电状态触发第一断路器的状态变化，第二电路的通电状态触发第二断路器的状态变化，控制电路根据第一断路器的状态和第二断路器的状态触发第一接触器的状态变化。本发明的供电扩展系统通过各元件的机械连锁反应对地铁进行供电，避免了由于控制信号错误而造成的供电方式混乱，提高了供电系统的可靠性。
摘要（英）：

The invention provides an auxiliary power supply expansion system for a metro vehicle. The auxiliary power supply expansion system comprises a main circuit, a control circuit, a first circuit breaker, a second circuit breaker and a first contactor; the first contactor is in a closed position when power-on and is in a non-closed position when power-off; the main circuit comprises a first circuit and a second circuit, and the first contactor is connected with the first circuit and the second circuit; the first circuit is connected with the control circuit through the first circuit breaker, and the second circuit is connected with the control circuit through the second circuit breaker; a power-on state of the first circuit triggers a state change of the first circuit breaker, a power-on state of the second circuit triggers a state change of the second circuit breaker, and the control circuit triggers a state change of the first contactor according to a state of the first circuit breaker and a state of the second circuit breaker. The auxiliary power supply expansion system provided by the invention has the benefit that a metro is powered through the mechanical chain reaction of all the components, so that the power supply mode confusion caused by a control signal error is avoided, and the reliability of the power supply system is improved.
