由中车永济电机有限公司、日立永济电气设备(西安)有限公司与西安市地下铁道公司联合开发的具有世界先进水平的地铁车辆异步牵引系统项目方案,在西安通过了技术方案审查,未来将以西安地铁1号线、2号线牵引系统自主化替代为载体进行进一步实际验证。该项目的实施,可以实现我国地铁车辆牵引系统的完全自主化,可以替代进口产品;项目自主研发的、具有完全自主知识产权的地铁
The project of asynchronous traction system for metro vehicles with world advanced level jointly developed by Zhongji Yongji Electric Co., Ltd., Hitachi Yongji Electrical Equipment (Xi’an) Co., Ltd. and Xi’an Subway Company passed the technical scheme review in Xi’an, Taking Xi’an Subway Line 1 and Line 2 as the carrier, the traction system was replaced by the carrier as a further practical verification. The implementation of this project can completely realize the independence of the traction system of the subway vehicles in our country and can substitute for the imported products. The subway independently developed by the project has completely independent intellectual property rights
