变频器在电机启动与调速中的应用分析

Analysis on the Application of Frequency Transformer for Generators Speed Adjustment

变频器的容量选择也不是一个简单问题 ,不能仅仅以电动机的容量为准。特别是对变频器产生的高次谐波的干扰问题以及对现场的危害要引起重视 ,对变频器产生的不可避免的电路干扰 ,尽管难以消除 ,采用适当的装置也是可以抑制的。

The content of a frequency transformer is not a simple question and not only decided by the content of the generator.Especially the interruption produced by the frequency transformer should be paid more attention so that it can be restrained by suitable equipments although it can not be avoided fully.
