如果插座的零火线接反了,造成的后果有两个:1.不规范,开始的“左零右火”据说是为了安全——右手拔插头,右手拇指容易接触到插头的插脚,成为触电点。不过现在的插座都很紧了,不需要考虑拔插插头时触电的问题。更多的是一种规范(这种规范已经写入国标),为的是方便检修。不利于区分零火线——个别电器是需要在使用时区分零火线的。这种电器必须使用三脚插头,而三脚插头的左右是固定的。此时插座内的接线只要正确,它就可以通过区分插脚方向,来判断电线是零线还是火线。

另外,频率能够在电机的外面调节后再供给电机,这样电机的旋转速度就可以被自由的控制。以控制频率为目的的变频器,是做为电机调速设备的优选设备。n=60f/pn:同步速度f:电源频率p:电机极对数结论:改变频率和电压是优的电机控制方法如果仅改变频率而不改变电压,频率降低时会使电机出于过电压(过励磁),导致电机可能被烧坏。因此变频器在改变频率的同时必须要同时改变电压。输出频率在额定频率以上时,电压却不可以继续增加,高只能是等于电机的额定电压。
