Abstract

The invention discloses a train power cube for an alternating current drive locomotive, comprising two same train power sub-cubes, wherein the two train power sub-cubes are connected with a microcomputer control system; each train power sub-cube comprises an independent main circuit and a power supply control system; the power supply control system is used for receiving signals of passenger trains, and has a centralized control function of ensuring the locomotive to supply power to the passenger trains safely. The train power cube for the alternating current drive locomotive, disclosed by the invention, overcomes the problems that the whole systematization is worse and the locomotive is inconvenient to back to a garage for overhauling in the prior art.

Description

technical field [0001] The invention relates to the technical field of locomotives and trains, in particular to a train power supply cabinet for AC drive electric locomotives. Background technique [0002] In order to promote energy saving and consumption reduction of railways and improve transportation efficiency, the Ministry of Railways has canceled power generation cars on a large scale and promoted the DC600V train power supply system for electric locomotives. [0003] At present, electric locomotive train power supply cabinets have been used on a large scale on AC / DC electric locomotives of models SS7C / SS7D / SS7E / SS8 / SS9 / SS9G. [0004] The power supply systems of all AC-DC electric locomotive trains are similar in principle, and they are all controlled by a centralized power supply control system with two independent power supply circuits. The biggest difference between various AC and DC electric locomotive train power supply cabinets is how to arrange the components i...
