Abstract

The invention provides an integrated converter cabinet, comprising a cabinet body, a cooling system, a traction converter, an auxiliary converter and a train power supply unit. The cooling system comprises a cooling component and a cooling tower. The traction converter, the auxiliary converter, the train power supply unit and the cooling component are arranged inside the cabinet body, and the cooling tower is arranged outside the cabinet body. The cooling component is used for cooling the traction converter, the auxiliary converter and the train power supply unit. By integrating the train power supply unit into the converter cabinet, the space occupied by vehicle assembly is reduced, the vehicle layout is more compact, the vehicle weight is reduced, and the requirement for a light vehicleis met. Moreover, the train power supply unit is cooled by the cooling component of the converters, and the heat dissipation effect is better.

Description

technical field [0001] The invention relates to the technical field of electric locomotives, in particular to an integrated converter cabinet. Background technique [0002] Electric locomotives are developing in the direction of high integration and high output. The converter cabinet is the core component of electric locomotives, which undertakes the major task of converting grid energy to drive traction motors and auxiliary equipment on vehicles. [0003] In the prior art, in order to increase the integration of electric locomotives, cooling components, traction converters or traction auxiliary integrated converters are usually integrated into the converter cabinet, and the train power supply unit is integrated into the train power supply cabinet. On the one hand, the assembly of multiple integrated cabinets requires a large space, which is not conducive to the compactness of the vehicle space layout, and the use of multiple integrated cabinets makes the weight of the elect...
