Rail transit vehicle and charging converter thereof

Abstract

The invention discloses a rail transit vehicle and a charging converter thereof, which are characterized in that a rectification power module is arranged in a rectification cabinet, a rectification module, a cooling fan, an input circuit breaker and a filtering magnetic element are stacked and integrated in the vertical direction, and the rectification power module is arranged in parallel; chopping power modules are arranged in the chopping cabinet, chopping modules, heat dissipation pieces and chopping magnetic elements are stacked and integrated in the vertical direction, and the chopping power modules are arranged in parallel; and a control circuit module, an input circuit module, an isolation switch module and an output circuit module which are electrically connected with the rectification power module and the chopping power module are integrated in the control cabinet. Rectified power and chopped wave power are modularized to serve as a functional unit, and meanwhile, the functional unit is also a minimum manufacturing unit when leaving a factory. When the power needs to be changed, the required number of chopping power modules and rectifying power modules can be connected inparallel. Product configuration and production are rapidly carried out according to market requirements, the design and production time is shortened, and the product competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail transit vehicle and a charging converter thereof. Background technique [0002] At present, trams and trolleybuses, as modern means of transportation, are more and more adopted by various cities. For the sake of city beauty and construction cost, the conventional catenary is canceled, and usually the trams use the form of on-board capacitors, which are charged with charging converters. Because the battery capacity configuration of each tram is different, charging converters with different power levels are required, so many charging converters cannot be used universally. If it is configured according to the maximum capacity, the product cost will be high. If the design is carried out according to the minimum capacity, there will be a phenomenon of many types of products and small quantities, which is not conducive to the design and production of product platforms, re...

AI Technical Summary

Problems solved by technology

Because the battery capacity configuration of each tram is different, charging converters with different power levels are required. Therefore, many charging converters cannot be used universally.

If configured according to the maximum capacity, the product cost will be high

If the design is carried out according to the minimum capacity, there will be a phenomenon of many types of products and small quantities, which is not conducive to the design and production of product platforms, resulting in repeated customized production

In addition, the production staff takes a long time to trial-produce new products, which brings great troubles to the production site and manufacturing, and at the same time, the product cost will increase accordingly
