The invention relates to the structural layout of a converter cabinet, in particular to a converter cabinet for a hybrid shunting locomotive, which comprises a frame cabinet body, and the front side wall and the rear side wall of the frame cabinet body are partitioned according to functions; an air-cooling heat dissipation air duct is arranged in the frame cabinet body, mounting positions for different devices are arranged in the air-cooling heat dissipation air duct, a first access door is arranged on the left side wall of the air-cooling heat dissipation air duct, and a second access door is arranged on the right side wall of the frame cabinet body; the outer surfaces of all areas of the front side wall and the rear side wall of the frame cabinet body are connected with detachable door plates, the detachable door plates arranged at the cooling device area are air inlet net plates, and the surfaces, not covered by the access door, of the left side wall and the right side wall of the frame cabinet body are covered with skins. According to the invention, functions of traction current transformation, auxiliary current transformation, power battery charging, storage battery charging and the like are integrated in a limited space of a locomotive; the structural strength of the converter cabinet and the lightweight design of the cabinet body are ensured, and meanwhile, the heat dissipation requirements of heating electrical elements of the converter cabinet are met.

    本发明涉及变流柜结构布局,具体为一种混合动力调车机车用变流柜,其包括框架柜体,框架柜体前侧壁和后侧壁处按照功能进行区域分隔;框架柜体中设置有风冷散热风道,风冷散热风道中设有不同装置的安装位,风冷散热风道的左侧壁上设置有第一检修门,框架柜体的右侧壁上设置有第二检修门;框架柜体的前侧壁以及后侧壁的各区域外表面均连接有可拆卸门板,冷却装置区域处设置的可拆卸门板为进风网板,框架柜体的左侧壁和右侧壁上没有被检修门覆盖的表面覆盖有蒙皮。通过本发明使得在机车有限空间内集牵引变流、辅助变流、动力电池充电和蓄电池充电等功能于一体;在保证变流柜结构强度、柜体轻量化设计的同时满足变流柜发热电气元件的散热需求。
