隨著變頻技術的提高,通用變頻器的市場日益繁榮,變頻器的價格下降,使其大量應用成為可能。采用變頻調速可以實現軟起動和無級調速,提高生產機械的控制精度、生產效率和產品質量,有利于生產過程的自動化,使交流拖動系統具有優良的控制性能。
但在實際應用中,現場的粉塵、溫度、電源質量等對變頻器有較大影響;同時變頻器的大量應用也會帶來一些負面影響,如高次諧波、干擾、電動機發熱等。本文主要針對應用和維護中需注意的問題做一探討。
對變頻器的干擾基本類型及抗干擾措施
1、靜電耦合干擾
靜電耦合干擾是指控制電纜或通信總線與周圍電氣回路的靜電耦合,在電纜中產生的電勢。可以采取如下措施:
(1) 遠離電源電纜、大容量接觸器以及其他產生較強磁場設備的電源線路。
(2) 在電纜間設置屏蔽導體,再將屏蔽導體接地。
