浅谈轨道交通牵引逆变器质量管控

Quality Control of Traction Inverter in Rail Transit

目前拥有地铁线路较多的大城市,地铁车辆运行时间较长,牵引设备大都超出原厂质保。原厂设备价格高昂,供货周期较长。目前进行牵引设备大修的国内厂家较少,且随着近年来地铁行业蓬勃发展,进入大修阶段的地铁车辆原来越多,牵引设备大修行业有较大的前景。

At present,there are many metro lines in big cities,metro vehicles run for a long time,and traction equipment is mostly beyond the original quality assurance. The price of the original equipment is high and the supply cycle is long. At present,there are fewer domestic manufacturers carrying out traction equipment overhaul,and with the rapid development of the Metro Industry in recent years,the more metro vehicles entering the overhaul stage,the traction equipment overhaul industry has greater prospects.
