Abstract

The invention provides a traction converter device box and a vehicle. The traction converter device box comprises a first power module platform, a second power module platform, a control platform, a contactor platform, a resistor platform, a capacitor platform, a center pipeline platform, wherein each platform is integrated with at least one component; the first power module platform is connected with the control platform and the capacitor platform; the second power module platform is connected with the resistor platform and the contactor platform; and the first power module platform, the second power module platform, the control platform, the contactor platform, the resistor platform and the capacitor platform are connected with the center pipeline platform. Therefore, the box is not easy to deform after being assembled and combined; the dimensional tolerance is small; assembly work efficiency is improved; and the box is convenient to assemble, disassemble and maintain.

Description

technical field [0001] The invention relates to mechanical technology, in particular to a box body of a traction converter and a vehicle. Background technique [0002] The box structure of the traction converter on the existing high-speed EMU adopts the steel plate welding method, that is, the whole box is assembled by direct welding of the steel plate, the process is difficult, the welding is easy to deform, and the dimensional tolerance is large. When assembling, the components are installed directly in the entire box, instead of installing the components of each platform first, and then splicing and assembling each platform. Therefore, the assembly is difficult and the assembly efficiency is low. Contents of the invention [0003] The invention provides a traction converter box body and a vehicle, which are used to meet the technical requirements of the existing high-speed EMU vehicles for convenient design, assembly and maintenance of the traction converter device. ...
