要想变频器省电就一定要降低频率,下降值越大,节电就越多。不降低频率,变频器是不能省电的。变频器要省电是有一定条件的。在不影响使用的条件下,适当改变变频器在运行参数后,把不合理运行参数所消耗的电能节省下来,就可做到从一般运行转变成省电经济运行。
1、跟电动机负载率有关。负载率在10%~90%时,节电率最多约8%~10%,负载率低相应节电率高些。但无功节电率大约40%~50%,是不计电费的。


2、跟原来的运行的工况参数值的合理程度有关。例如,功率、电压、转速等可调节的量值大小有关,可调整量大,则节电率就高,否则相反。
3、跟电动机工作方式有关。例如,连续运转、短时运转、间歇运转的节电量是不同的。
4、跟电动机开动时间长短有关。例如,一天开机24h,一年开365天的节电量就大
5、跟电动机本身功率大小有关。同样节电率下,功率大的节电量值大,经济效益就大。
6、跟公司生产设备有关。首先要选产品电耗大的、产品成本高的、现用的调速方式是不够经济合理的设备加以改造,改用变频器后就能有立竿见影、事半功倍的效果。
