变频器的作用
变频器或变频驱动器(VFD)是一种电气设备,作用是将一种频率的电流转换为另一种频率的电流。变频前后电压一般相同。变频器通常用于对用于驱动泵和风扇的电机进行速度调节。
变频器的作用有哪一些?它有哪些功能呢?
1、变频器的作用主要是调整电机的功率、实现电机的变速运行,以达到省电的目的。
2、同时变频器的作用可以降低电力线路电压波动,因为电压下降将会导致同一供电 *** 中的电压敏感设备故障跳闸或工作异常。
3、采用了变频器后,变频器的作用能在零频零压时逐步启动,这样能更大程度的消除电压下降,发挥更大的优势。
同时变频器的作用功能还包含以下功能:
1.可以减少对电网的冲击,就不会造成峰谷差值过大的问题。
2.可以加速功能可控,从而按照用户的需要进行平滑加速。
3.电机的和设备停止方式可控,使整个设备和系统更加安全,寿命也会相应增加。
4.控制电机的启动电流,充分降低启动电流,使电机的维护成本降低。
5.可以减少机械传动部件的磨损,从而降低采购成本,同时可以提高系统稳定性。
6.降低了电动机启动电流,提供更可靠的可变电压和频率。
