The invention discloses a mining electric wheel dumper traction converter, and relates to the technical field of traction converters, the mining electric wheel dumper traction converter comprises a cabinet body, a wire inlet box and a wire outlet box, the wire inlet box and the wire outlet box are arranged on the cabinet body, and a wire connected to a rectification module penetrates through the wire inlet box to be electrically connected with a synchronous power generation module; a wire connected to the inversion chopping module penetrates through the wire outlet box and is electrically connected with the traction motor TM1 and the traction motor TM2. When a vehicle runs, the air inlet amount is increased through the vehicle speed and the windward port, the heat dissipation performance is improved, the protective net prevents large-particle foreign matter from entering the cabinet body, the automatic opening and closing type shutters are additionally arranged on the front portion or the rear portion of the protective net, the shutters are automatically opened when the wind speed exists, and the shutters are closed when the wind speed does not exist or the vehicle stops. After the contactor B1, the first chopper and the second chopper are controlled, energy is consumed on the braking unit, kinetic energy of the vehicle is converted into electric energy, a friction-free electric braking mode is achieved, and the braking purpose is achieved.

    本发明公布一种矿用电动轮自卸车牵引变流器,涉及牵引变流器的技术领域,包括柜体、进线盒和出线盒,所述进线盒和出线盒设置在柜体上,整流模块上接的导线穿过进线盒与同步发电模块电连接,逆变斩波模块上接的导线穿过出线盒与牵引电机TM1和牵引电机TM2电连接;车辆行驶时利用车速和迎风口增加进风量,提升散热性能,防护网防止大颗粒的异物进入柜体,在防护网的前部或者后部增加自动开合式百叶窗,有风速时自动打开百叶窗,无风速或者车辆停止时关闭百叶窗。接触器B1、第一斩波器、第二斩波器控制之后,将能量在制动单元上进行消耗,将车辆的动能转换为电能,实现无摩擦的电制动方式,达到制动的目的。
