Description

technical field

[0001] The invention mainly relates to the field of electric locomotives, in particular to a power supply device suitable for electric locomotives. Background technique

[0002] At present, electric locomotives are basically divided into two types:

[0003] One is a vehicle with a train inverter, which requires the DC train power supply cabinet on the locomotive to provide DC600V power supply, which is supplied to the vehicle equipment after passing through the vehicle inverter; that is, the train power supply cabinet on the locomotive and the inverter on the traction vehicle The train power supply cabinet takes power from the winding of the locomotive traction transformer, rectifies it into DC 600V, and supplies it to the traction vehicle. After being converted into AC 380V by the vehicle's own inverter, it supplies power to the vehicle load (air conditioning, lighting, etc. ) use, that is, the train power supply scheme using centralized rectification for l...
