变频控制技术已经相当成熟,由于它的显著节能,降耗作用,使得利用变频器已经是一种趋势和潮流。在国外发达国家使用已经相当普遍,而在国内这一变频技术的利用才刚刚起步,如现在较流行的家用变频空调器、变频洗衣机等,但在系统化大型项目上使用变频技术还比较少见。特别是在大型的旧、老设备上使用变频器以完善、提高其性能的还没有应用实例。
Frequency control technology has been quite mature, because of its significant energy saving, reducing consumption, making use of the inverter has been a trend and trend. The use in developed countries has been quite common in foreign countries. However, the use of this variable frequency technology has just started in China. For example, the more popular household inverter air conditioners and frequency conversion washing machines are now in use. However, the use of frequency conversion technology in systematic large-scale projects is still relatively rare. Especially in the large old and old equipment to improve the use of frequency converter to improve its performance has not been an application example.
