关于变频调速系统抗干扰问题的探讨

A Discussion about the Anti-interference Problem in the Variable Frequency Speed Regulation System

针对变频器广泛应用的现状,从变频调速系统干扰的种类及传播方式入手,提出几种抗干扰措施,并举例说明这些措施都可有效地避免各种干扰对系统的影响。

Aimed at the current situation of the frequency converter＇s increasing use, such anti-interference measures as reasonable wiring, seriesing reactor, seriesing filter, adding decoupling electric capacity and etc were put forward to eliminate the propagation modes of the interference in the variable frequency speed regulation system. All these measures could prevent the system efficiently from the infection of all kinds of interference and obtained preferable effect in practical application.
