Abstract

The invention provides a traction converter. The traction converter comprises a shell assembly; a first circuit assembly, wherein the first circuit assembly is located in the shell assembly; and a power module, comprising a second circuit assembly, the second circuit assembly being located in the shell assembly, the second circuit assembly and the shell assembly being movably connected with each other, and the second circuit assembly and the first circuit assembly being electrically connected with each other. According to the traction converter provided by the invention, the power module is separately connected with other circuit components of the converter, so that when the traction converter is overhauled and maintained, the power module can be moved and overhauled independently, overalldisassembly and assembly are not needed, and the overhauling and maintenance convenience is improved. The invention further provides a traction converter control method.

Description

technical field [0001] The invention belongs to the field of traction converters for rail trains. Background technique [0002] At present, in traction converters for rail transit trains, the power module and the supporting capacitor are usually designed in one piece. [0003] However, the integrated design of the power module and the supporting capacitor increases the volume and mass of the traction converter; at the same time, the power module and the supporting capacitor need to be disassembled as a whole during later inspection and maintenance, which is not conducive to later inspection and maintenance. Contents of the invention [0004] Aiming at the technical problem of inconvenient inspection and maintenance of the existing power module of the converter, the present invention provides a converter, which separates the power module from other circuit components of the converter, and performs maintenance on the traction converter , the power module can be inspected an...
