Locomotive traction inverter

Abstract

The invention discloses a locomotive traction inverter, which comprises a cabinet body, and is characterized in that the cabinet body is divided into two layers, a power module 1 and a power module 3 are parallelly installed at the right side of the cabinet body at the upper layer, two support capacitor are parallelly installed at the left side of the cabinet body at the power layer, in the same way, a power module 2 and a power module 4 are parallelly installed at the right side of the cabinet body at the lower layer, and two support capacitors are parallelly installed at the left side of the cabinet body at the lower layer; a cooling fan is respectively installed between the support capacitors located in the cabinet body at the upper and lower layers; an installation plate is arranged at the front side of the cooling fan located at the upper layer, a change-over switch is arranged at the rear side of the cooling fan located at the upper layer, the installation plate is provided with a grounding resistor, a voltage detecting plate and a voltage sensor; discharge resistors are arranged at the cabinet body front and rear side surfaces of the power modules; and a secondary terminal X4, a secondary terminal X2 and a secondary terminal X1 are arranged at right lower part of the cabinet body. The locomotive traction inverter disclosed by the invention is different from previous locomotive traction inverters in design structure, and requirements in space, electrical performance and mechanical performance of the inverter are met at the same time.

Description

technical field [0001] The invention relates to railway locomotive equipment, in particular to an arrangement structure of a railway locomotive traction inverter. Background technique [0002] Railway locomotives are important equipment related to personnel safety, especially in the era when Chinese railways are connected to the world and locomotives are going global, the locomotives are required to have very high reliability. Therefore, it is very difficult for the locomotive traction inverter device to increase the high power density in a narrow space and meet the electrical performance requirements. [0003] At present, the structures of traction inverters for locomotives are different, and most of them are water-cooled cooling structures, while air-cooled inverters for internal combustion locomotives have not been reported and implemented yet. Contents of the invention [0004] The object of the invention is to provide a locomotive traction inverter by designing and l...
