HIGH-VOLTAGE NETWORK SIDE CIRCUIT OF MOTOR TRAIN IN MOTOR TRAIN UNIT AND CONTROL METHOD THEREFOR

WIPO Patent Application WO/2019/218523

A1

A high-voltage network side circuit of a motor train in a motor train unit and a control method and device therefor, a computer readable storage medium, the high-voltage network side circuit comprising a plurality of receiving branches (1) connected in parallel, a bypass branch (2), a mode input detection circuit (3) and a controller (4), wherein the bypass branch (2) comprises a high-voltage disconnecting switch of which a first end is connected to an output end of the receiving branches (1), and a second end of the high-voltage disconnecting switch serves as a bypass point and is connected to bypass points of other motor trains; the mode input detection circuit (3) is used to detect a mode selection instruction inputted by a user; and the controller (4) is used to send a closing instruction to the high-voltage disconnecting switch when the user inputs a double-motor-train traction mode instruction, and send a shut-off instruction to the high-voltage disconnecting switch when the user inputs a single-motor-train traction mode instruction; and any of the receiving branches (1) is controlled to turn on so as to output a power supply. The present application may improve the flexibility and safety of the circuit under different grouping modes.
