Problems solved by technology

In the second way, although the vehicle inverter is saved, it is necessary to add a power generation car dedicated to power generation
[0007] (1) It is necessary to configure the train power supply cabinet and the vehicle inverter two devices or the power generation car, the cost is high, and there are difficulties in the installation space of the train power supply cabinet and the later maintenance of the vehicle inverter
[0008] (2) The traditional train power supply cabinet draws power from the train supply winding of the traction transformer. When the locomotive is over-phased, the train supply winding has no power input and cannot supply power to the traction vehicle

Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Such as figure 1 As shown, the electric locomotive train power supply device of the present invention includes a main transmission system, an auxiliary converter system and a train power supply system, wherein the main transmission system provides traction kinetic energy for the locomotive and converts the kinetic energy of the locomotive into electric braking energy to realize traction and electric braking functions. The auxiliary converter system is integrated in the traction converter of the main drive system and is responsible for providing power for the auxiliary equipment of the locomotive. The train power supply system is integrated in the traction converter of the main drive system and is responsible for providing power for the traction train, including on-board air conditioners and lighting equipment. It can be seen ...

Abstract

The invention discloses a train power supply device for an electric locomotive, which comprises: a main transmission system, which is used to provide traction kinetic energy for the locomotive and convert the kinetic energy of the locomotive into electric braking energy; an auxiliary converter system integrated in the main transmission system The traction converter is used to provide power for locomotive auxiliary equipment; the train power supply system is integrated in the traction converter of the main drive system to provide power for traction trains. The invention has the advantages of simpler structure of the whole machine, lower cost, good power supply effect and the like.

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...
