摘要
根据地铁车辆三相鼠笼式异步电动机启动过热而容易出现故障的情况,对电机的发热量进行计算,通过实验得出启动频率变化时电机温升随之变化的情况,得到通过控制牵引逆变器频率实现地铁车辆异步电机启动过热防控的方法。
Overheating and failure of Metro Vehicles in three- phase squirrel cage induction motor occurs during the startup process,this paper is calculated by the heat of the motor,by experiment while starting frequency changes along with changes in motor temperature. Obtained by controlling the traction inverter frequency induction motor starts to realize mtro vehicles overheating prevention and control methods.
