蓄电池工矿电机车是现代地下工程施工的重要运输牵引设备,国内工矿电机车几十年来主要采用直流传动方式,在启动、制动、效率、节能等方面都已不太适应以盾构及TBM等大型掘进设备为施工主体的地下工程施工要求。针对上述情况,介绍了一种大吨位蓄电池直交变频工矿电机车,在介绍其主要性能参数、基本工作原理、主要结构的同时,重点分析了该工矿电机车与传统的设备相比,在启动性能、制动性能、大功率变频控制装置水冷散热、采用Y系列普通交流电动机等方面的特点。
Battery mining electric locomotive is an important transportation traction equipment in modern underground construction. The domestic industrial and mining electric locomotives mainly use DC transmission mode for decades, and have not been adapted to shield, TBM, etc. in start-up, braking, efficiency and energy saving Large excavation equipment for the construction of the main underground construction requirements. In view of the above situation, this paper introduces a large tonnage battery AC-DC industrial and mining electric locomotive. The main performance parameters, basic working principle and main structure are introduced. Meanwhile, compared with the traditional equipment, , Braking performance, high-power inverter cooling water cooling device, the use of Y series AC motors and other characteristics.
