摘　　要：采用电动盘车,可以提高检修效率。以SF150-96/15600水轮发电机为例,根据其结构组成,由电磁感应定律建立发电机定转子启动电流计算模型,通过在发电机组检修前后盘车现场调试与应用,证明了计算模型所推导的电动盘车定转子电流的合理性。电动盘车虽然增加了部分电气设备,控制电路相对复杂,但操作简单、方便可靠、停落点精确、自动化程度高,能准确测量出检修发电机组的轴线,保证发电机轴的摆度和瓦温均在规定范围内。Electric turning gear can be used to improve the maintenance efficiency of hydro-turbine generator units.Taking SF150-96/15600 hydro-turbine generator unit as an example,a calculation model of the startup current for generator stator and rotor is established according to the electromagnetic induction theory and then verified by practical testing and application.The electrical structure of the electric turning gear is also introduced.Although some extra electrical equipment is needed and the control circuit is relatively complicated,the electric turning gear is of more advantages such as simple operation,good reliability and convenience,accurate stop point,high automation,and the ability to accurately measure the axis of the overhauled generator unit,which ensures the swinging and bearing temperature of the generator shaft are within the prescribed range.
