地铁车站低压配电系统电动机设备采用AC 660V配电的研究

Research on AC 660 V Distribution for Motor Equipment in Low‑voltage Distribution System of Metro Stations

通过分析电动机定子绕组接线形式,输入电压与电磁功率、转矩关系,以及电动机负荷配电系统元件、电缆,从而得出地铁电动机设备均可采用AC 660V供电的结论。通过对比分析说明地铁电动机设备采用AC 660V供电时,具有大幅节约有色金属,降低初期投资及减小线缆损耗的优势。

By analyzing the connection form of the motor stator winding,the relationship between input voltage and electromagnetic power,torque,as well as the components and cables of the motor load distribution system,this article concludes that AC 660 V power supply is applicable to all metro motor equipment.Through comparative analysis,this article also explains the advantages of substantial savings of nonferrous metals,reduction of initial investment and reduction of cable losses to metro motor equipment if AC 660V power supply is adopted.
