Traction converter cabinet used for electric tram car

Abstract

The present invention discloses a traction converter cabinet used for an electric tram car. The cabinet comprises a cabinet body. The cabinet body comprises a left connecting plate, a right connectingplate, an upper connecting plate and a lower connecting plate. The left connecting plate, the upper connecting plate, the right connecting plate and the lower connecting plate are successively connected from head to tail. The left connecting plate is provided with a first air outlet, the right connecting plate is provided with a second air outlet, and the first air outlet and the second air outlet are in a same straight line. The space between the first air outlet and the second air outlet forms a first air passage with the cabinet body. The lower connecting plate is provided with an air inlet, and the air inlet forms a second air passage with cabinet body. The first air passage and the second air passage are perpendicularly connected to form a T-shaped structure. The cabinet body is provided with a frame used for installing a fan, the frame is located at the intersectional part of the first air passage and the second air passage, and the frame is connected with cabinet body. Withoutthe need of adding heat dissipation device(s) in a traction converter, the heat is dissipated only via the air passages of the T-shaped structure, the designed mechanism is simple without the occupation of the volume of the cabinet body, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of traction converters, in particular to a traction converter cabinet for a guide rail car. Background technique [0002] As the core component of the guideway tram, the traction converter of the guideway tram converts the input 750V direct current into the three-phase alternating current required by the traction motor through inverter and chopping, so as to meet the normal operation of the guideway tram. [0003] The existing guide rail tram traction converter includes a cabinet body, and a water-cooling forced heat dissipation device is arranged inside the cabinet body. The water-cooling forced heat dissipation device includes a water-cooling pipeline, and the water-cooling pipeline is fixed in the cabinet body by bolts, and the orientation of the water-cooling pipeline ensures The heat dissipation of the traction converter of the guide rail tram, but the installation of the water-cooled pipeline heat diss...
