随着我国铁路运输的迅速发展,电力机车内燃机车已成为重要的牵引动力。对机车,车辆用蓄电池组充电设备的研制和生产,是一项十分迫切的任务。目前我国已有的充电设备大都是硅整流器。由于电网电压的波动和蓄电池电势的变化,充电过程中要经常手动调整,充电耗时较长,而且质量难于保证,远远不能适应当前铁路运输发展的需
With the rapid development of China’s railway transportation, diesel locomotives for electric locomotives have become an important traction power. The locomotive, vehicle battery charging equipment research and production, is a very urgent task. At present, most of our existing charging equipment is a silicon rectifier. Due to the fluctuation of grid voltage and the change of battery potential, the charging process should be adjusted frequently and the charging takes a long time, and the quality is hard to guarantee, far from being able to meet the needs of the current railway transportation development
