【摘要】 在比较各种软起动方式后,给出一种新型磁控电机软起动方案,即在电动机定子回路中串入磁饱和可控电抗器来实现电机的软起动,保证电动机按负载要求的起动特性平滑起动,有效地降低对电网电压波动的影响。更多还原

【Abstract】 After comparing with various kinds of soft-start scheme, comes a new magnetic control soft-start of motors, i.e. in the stator circuit, a magnetic saturation controllable reactor is series-wounded. It makes the motor starting smoothly followed with the starting characteristics required by the load, so as to reduce the voltage variation in the power line net effectively.更多还原
