IC693MDL730RR进口原装
IC693MDL730RR 变频器缺相故障除了输入缺相外,还有一种是输出缺相,这将直接导致电机缺相运行。缺相时,电机静止时启动,电机就转不起来。若是在运行中缺相十分危险,电机电流增大1.2倍,发热严重,震动加剧,急易烧坏电机。变频器通过检测输出电流,就可以判断三相输出是否缺相。 变频器输入缺相的检测方法 当变频器不发生缺相的正常情况下工作时,Udc上的电压如图2所示,一个工频周期内将有6个波头,此时直流电压Udc将不会低于470V,实际上对于一个7.5kW的变频器而言,其C的值大小一般为900uf,当满载运行时,可以计算出周期性的电压降落大致为40V,纹波系数不会超过7.5%。而当输入缺相发生时,一个工频周期中只有2个电压波头,且整流电压低值为零。此时在上述条件下,可以估算出电压降落大致为150V,纹波系数要达到30%左右。
