6. the power supply device controller sends working signals to the power supply cable control system and the mechanical arm control system, the mechanical arm 9 pulls out a motor train unit connector 12 connected with the motor train unit, meanwhile, the cable controller controls the corresponding cable drum 3 to rotate, the power supply cable 5 is withdrawn, and the mechanical arm 9 inserts the motor train unit connector 12 back into the cable box 1; and moving the ground power supply device back to the front of a power cabinet of the ground power supply system of the motor train unit, enabling the mechanical arm 9 to act, pulling out the universal connector 13 inserted into the power cabinet, controlling the corresponding cable drum 3 to rotate by the cable controller, withdrawing the power supply cable 5, and inserting the universal connector 13 back into the cable box 1 by the mechanical arm 9.
The special case is as follows: when abnormal operation or misoperation occurs, if a main circuit breaker of the ground power supply system of the motor train unit is in a switching-on state and the system is electrified, when the universal connector 13 or the motor train unit connector 12 matched with the motor train unit is inserted or pulled out by the mechanical arm 9, the power supply interlocking controller firstly sends a forced tripping instruction to the ground power supply system of the motor train unit, and next operation can be performed after no power is supplied.
Special description: the ground power supply system of the motor train unit externally matched with the device can supply power for a power distribution cabinet which is commonly used in a garage, and can also supply power by adopting a mobile power supply.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
