Abstract

The invention relates to the field of rail transit and electrics, and discloses a rail transit vehicle traction transformer assembly which mainly comprises a support assembly used for being fixedly connected to the bottom of a vehicle and arranged in the middle relative to the bottom limit of the vehicle. The traction transformer body is mounted at one end of the bracket assembly; the cooler assembly and the traction transformer body are suspended separately, and the cooler assembly extends to the two sides of the support assembly and is used for circularly cooling the cooling oil in the traction transformer body. The traction transformer assembly of the rail transit vehicle is suitable for being arranged at the bottom of the vehicle, cooling oil of the traction transformer body is cooled through walking air and the cooler assembly, the cooling power is large, a forced ventilation cooling fan can be omitted, noise of the transformer is greatly reduced, the efficiency of the transformer is improved, overhaul and maintenance work is greatly reduced, and the cost is reduced. The whole vehicle arrangement and control are simplified, the fault occurrence probability is reduced, the reliability of the whole vehicle and the traction transformer is improved, and the whole-life-cycle operation and maintenance cost of the transformer is greatly reduced.

本申请涉及轨道交通及电气领域，并公开一种轨道交通车辆牵引变压器总成，主要包括支架总成，用于固接于车辆底部并相对车辆底部限界居中设置；牵引变压器本体，安装于所述支架总成的一端；冷却器总成，与所述牵引变压器本体分开悬挂，且延伸至所述支架总成的两侧，用于将所述牵引变压器本体内的冷却油循环冷却。本申请所提供的轨道交通车辆牵引变压器总成适用于车辆底部布置，利用走行风和冷却器总成对牵引变压器本体的冷却油冷却，冷却功率大，可取消强迫通风冷却风机，大幅降低变压器噪声，提升变压器效率，大幅减少检修维护作业，精简整车布置和控制，降低故障发生概率，提升整车及牵引变压器的可靠性，大幅降低变压器全寿命周期运维成本。
