Problems solved by technology

[0006] (3) The existing high-speed EMU traction auxiliary converter lacks a fire alarm function for the entire converter device
[0007] (4) The water-cooling system design of the existing high-speed motor train traction auxiliary converter adopts a double water-cooling system. Although the structure is equal, the heat dissipation power is not necessarily symmetrical
In the case of inconsistent heat dissipation power, there will also be inconsistency in the heat exchange between water and air through the heat exchanger, which will affect the best performance of the overall heat dissipation performance

Abstract

The invention discloses a traction auxiliary converter. The traction auxiliary converter comprises a cabinet body, wherein the cabinet body is internally equipped with a main circuit, two sides of the cabinet body are provided with multiple elastic supporting assemblies, the elastic supporting assemblies comprise suspension seats and supporting rods, the suspension seats are fixedly mounted on a vehicle, the suspension seats are internally hollow, two sides of the suspension seats are provided with mounting holes, the suspension seats are internally provided with supporting seats, elastic members are arranged between the supporting seats and inner walls of the suspension seats, the supporting seats are provided with supporting holes opposite to the mounting holes, one ends of the supporting rods are fastened on the cabinet body, and the other ends of the supporting rods penetrate through the mounting holes and are then fixedly clamped in the supporting holes of the supporting seats. The traction auxiliary converter has advantages of simple structure, vibration resistance, reasonable layout, good heat radiation effect and reliable operation.

Description

technical field [0001] The invention mainly relates to the technical field of rail transit, in particular to a traction auxiliary converter. Background technique [0002] In recent years, with the development of my country's high-speed railway, the requirements of railway transportation for high-speed EMU vehicles are getting higher and higher. As the core component of the train traction system, the converter device has the most important performance requirements. At present, the traction system schemes of various traction suppliers are mainly divided into two types: main and auxiliary separation schemes and main and auxiliary integration schemes. The main and auxiliary separation scheme has low integration, and the decentralized equipment layout makes the bottom of the vehicle overcrowded. Sometimes it is difficult to meet the ventilation and heat dissipation requirements of key components, and it also brings certain difficulties to the vehicle equipment layout and vehicle...
