A high-voltage network side circuit of a power car in an EMU and a control method thereof

Abstract

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.

Description

technical field [0001] The present application relates to the technical field of rail vehicle power supply, and in particular to a high-voltage grid-side circuit of a power car in an EMU, its control method, equipment, and a computer-readable storage medium. Background technique [0002] With the development of science and technology in our country, considerable progress has been made in the field of rail transit technology. [0003] In the field of rail transit, an EMU refers to a train set composed of several power cars and several trailers. Among them, the power centralized EMU refers to the EMU with power units installed at both ends of the train, which has the advantages of easy maintenance and high safety. [0004] For the power centralized EMU, there are generally two marshalling modes, that is, single-power vehicle traction mode and dual-power vehicle traction mode. Among them, the single-powered vehicle traction mode is suitable for small passenger traffic scenari...
