Abstract:
A pantograph remote control circuit for an unmanned metro train includes a startup circuit of an auxiliary inverter emergency start relay, a control circuit of an auxiliary inverter energized relay, and a startup circuit of a pantograph raising relay. A first normally-open contact pair of the pantograph raising relay is serially connected to a pantograph raising electromagnetic valve and then connected to an output terminal of a battery. At the meantime, the bootstrap is remotely controlled by the internal ATC wake-up module when the power supply is fed by the battery, and there is no need for the driver to operate on the spot, thereby saving time for the driver from operations and reducing the potential misoperation of the driver.
