Control method and device for internal bypass relay of traction converter and storage medium

Abstract

The invention discloses a control method and device for a bypass relay in a traction converter and a storage medium, and relates to the technical field of train circuits, and the key points of the technical scheme are that the method comprises the following steps: determining a setting condition; determining a reset condition; detecting train state information and traction converter information; judging whether the train state information and the traction converter information meet a setting condition and a resetting condition or not; when the setting condition is met, a setting instruction corresponding to the relay is generated, and the relay is controlled to respond to the setting instruction; and when the reset condition is met, generating a reset instruction corresponding to the relay, and controlling the relay to respond to the reset instruction. Through the control method, the relay control logic can be optimized, the use frequency of the relay is reduced, the service life of the relay is further prolonged, the usability of the train traction converter is improved, the maintenance cost of the traction converter is reduced under the condition that hardware does not need to be added, and the overall maintenance cost of a motor train unit is further reduced.
