Performance detection method and device for cooling system of vehicle traction transformer, storage medium and terminal

Abstract

The invention discloses a performance detection method and device for a cooling system of a vehicle traction transformer, a storage medium and a terminal, and the method comprises the steps: obtaininga plurality of pieces of sample data from historical operation data of the cooling system of the vehicle traction transformer, wherein each piece of sample data comprises performance index influencefactor information and an associated performance index value; training by utilizing the performance index influence factor information and the associated performance index value to obtain a performance detection model; obtaining to-be-detected data in a preset time period, wherein the to-be-detected data comprises performance index influence factor information and associated performance index values; calculating an expected performance index value based on the performance index influence factor information in the to-be-detected data and the performance detection model; and calculating a deviation value between the performance index value in the to-be-detected data and the expected performance index value, and judging the performance of the vehicle traction transformer cooling system basedon the deviation value. Through the scheme of the invention, the cooling system of the vehicle traction transformer can be predicted and detected.

Description

technical field [0001] The invention relates to the technical field of health management of vehicle traction systems, in particular to a performance detection method and device, a storage medium, and a terminal of a vehicle traction transformer cooling system. Background technique [0002] The traction drive system of Chinese railway high-speed trains (for example, CRH series EMUs) is mainly composed of pantographs, high-voltage circuit breakers, traction transformers, traction converters, and traction motors. The traction transformer is an important part of the EMU. The 25kV single-phase AC power obtained by the pantograph is supplied to the primary winding of the traction transformer through the main circuit breaker. The secondary winding reduces the voltage to 1770V and supplies it to the traction / auxiliary converter. After the rectification, inverter and other links, it supplies power to the traction motor and auxiliary system equipment, and is also responsible for suppl...

Problems solved by technology

[0005] However, at present, the state detection and daily maintenance of the traction transformer cooling system of the EMU mainly focus on the faults that have occurred. There is still a lack of applicable methods and effective technologies for the early detection of faults, and the maintenance strategy is mainly scheduled maintenance and post-event maintenance. , cannot meet the requirements of improving the operating efficiency of high-speed EMUs and reducing operating costs
