变频器——当代电气节能的佼佼者

The Inverter—Enormous Potential in Saving Energy of Electrical

交流电机变频调速已成为当代电气传动的中枢。变频调速驱动笼式电机、绕线式电机(滑环短接)、同步机,可以达到"优质、增产、降耗、节电"的效果。节电率在15%～70%之间,采用变频调速可以节省4方面的电能,一为软起动,二为节省设计冗余,三为调速节电,四为节省无功。文章用详实的例证介绍了量大面变频器应用。

The inverter technology applied to adjust AC motor rotate speed has become the main force currently in the motor drive field.It can bring a great deal of benefit to user, such as improving quality, increasing production, reducing consumption,saving energy,and etc.15%～70% saving electronic rate, with this technology,there are four ways to save electricity energy:firstly, implementing soft start function; secondly, saving the additional power loss due to design redundancy; thirdly, saving the electricity energy due to the slowdown of motor rotatle speed;fourthly, saving the electricity energy due to inactiver current.In this article, many actual examples about the application of inverter were shown detailedly.
