Charger for medium-low speed maglev train

Abstract

The invention discloses a charger for a medium-low speed maglev train. The medium-low speed maglev train comprises a shell and a centralized control module and more than two direct-current power supply modules which are arranged in the shell in an integrated manner; and the centralized control module is connected with each DC power supply module, sends a control instruction to each DC power supply module, controls and starts each DC power supply module to access an input power supply for conversion, and then outputs a DC power supply. The charger can be applied to medium-low speed maglev trains, and has the advantages of the simple and compact structure, the low cost, the small weight and volume, the high integration degree and the good safety protection performance.

Description

technical field [0001] The invention relates to the technical field of medium and low speed maglev trains, in particular to a charger for medium and low speed maglev trains. Background technique [0002] The auxiliary power supply system for medium and low-speed maglev trains is a system that provides power for vehicle air conditioning systems, lighting, air compressors, control electronics for various systems, train monitoring systems, on-board signals and communications, etc. In order to meet the needs of different power supplies, it generally includes: DC330V Suspension power supply, AC380V auxiliary inverter, DC110V charger, 330V battery system, 110V battery system, power distribution cabinet and other necessary auxiliary equipment, among which DC3300V suspension power supply is connected to DC1500 DC power supply, and provides 330V DC after DC / DC conversion Power supply, DC110V charger is connected to three-phase 380V AC power supply, and outputs 110V DC power supply af...

AI Technical Summary

Problems solved by technology

[0004] 1. The independent layout of each power module requires a large amount of installation space and is heavy, making the weight and volume of the entire power system large;

[0005] 2. Each power module independently uses a set of control systems to configure multiple control modules. If it is necessary to configure two sets of control subsystems for the DC330V suspension power supply and DC110V charger, it will not only increase the system cost, but also make the control complicated.
