【摘要】 在比较各种软起动方式的基础上,提出了一种新型电机磁控软起动方案,即在电动机定子回路串入磁饱和可控电抗器来实现电机的软起动,能保证电动机按负载要求的起动特性平滑起动,有效地降低电机起动对电网的冲击。更多还原

【Abstract】 All kinds of soft-start schemes for electric machines are discussed and compared.A new magnetically controllable reactor soft-start scheme is proposed.During starting,the MCR is in series with the motor,which can ensure starting smoothly.The soft-start of the motor according to different load requirements,can effectively reduce the start inrush to the connecting power network.更多还原
