【摘要】 将Matlab的Simulink仿真环境的多物理仿真技术应用于三相变压器空载合闸的电机学教学过程中,通过三相变压器空载合闸的仿真实例,生动呈现了三相变压器各相电压、电流、绕组磁动势、总磁动势和磁通量的波形变化趋势,提供了一种电机学理论形象化、直观化的教学手段,尤其是在变压器实验中难以观察到的磁动势、磁通量的变化波形,有利于深化学生对变压器理论的理解。更多还原

【Abstract】 In this paper,the multi-physical simulation technology of Simulink simulation environment of Matlab is applied to the electrical teaching process of no-load closing of three-phase transformer.Through the simulation example of no-load closing of three-phase transformer,the waveform change trend of voltage,current,winding magnetomotive force,total magnetomotive force and magnetic flux of three-phase transformer are vividly presented,especially in presenting the the waveform of magnetomotive force and magnetic flux,which are difficult to be observed in transformer experiment.So a kind of teaching method of visualization is provided,which is helpful to deepen students’ understanding of transformer theory.更多还原
