变频节能技术的原理风机泵类负载的特点是转矩与转速的平方成正比(T∝n2),轴功率与电机转速的立方成正比(W=Tn∝n3)。传统风机之所以耗能大是因为设备在运行时风机都处于最高转速状态运行,系统是依靠调节风门的开度调节所需风量大小的。变频调速技术改变了输入端电源的频率,当系统所需风量减小时,所消耗的电能也随之减少,节能效果显著,下面就介绍一下变频器调速的原理。

  目前变频器对电机进行调速的技术方案有两种,一种方案是电流源变频调速,这种变频器用直流电抗器完成储能和滤波作用,用的比较少。另一种方案是电压源变频调速,这种变频器调速过程中将电网提供的恒压恒频电源进行移相整流,然后再进行串联叠加,其中间直流环节采用大容量电容器作为滤波和储能元件,采用三电平变频技术电压合成级数为三级,因此输入、输出需加滤波器才能保证其电能质量,这种方式元器件数量较少,电路拓扑较为简单,使用广泛。

  电压型变频调速器先将输入的恒压恒频交流电源(380V,50Hz)通过整流桥整流为直流电,然后经过滤波系统进行平滑滤波,经过微处理器控制逆变器改变导通开关的频率即可改变交流电的频率,最后将改变后的频率输出到需要调速的电机上,达到对风机泵类调速的目的。

诚信经营,质量为首,诚信至上,漳州鼎晟达自动化设备有限公司竭诚为您服务
