隨著變頻技術(shù)的提高,通用變頻器的市場(chǎng)日益繁榮,變頻器的價(jià)格下降,使其大量應(yīng)用成為可能。采用變頻調(diào)速可以實(shí)現(xiàn)軟起動(dòng)和無(wú)級(jí)調(diào)速,提高生產(chǎn)機(jī)械的控制精度、生產(chǎn)效率和產(chǎn)品質(zhì)量,有利于生產(chǎn)過(guò)程的自動(dòng)化,使交流拖動(dòng)系統(tǒng)具有優(yōu)良的控制性能。
但在實(shí)際應(yīng)用中,現(xiàn)場(chǎng)的粉塵、溫度、電源質(zhì)量等對(duì)變頻器有較大影響;同時(shí)變頻器的大量應(yīng)用也會(huì)帶來(lái)一些負(fù)面影響,如高次諧波、干擾、電動(dòng)機(jī)發(fā)熱等。本文主要針對(duì)應(yīng)用和維護(hù)中需注意的問(wèn)題做一探討。
對(duì)變頻器的干擾基本類(lèi)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?chē)姎饣芈返撵o電耦合,在電纜中產(chǎn)生的電勢(shì)。可以采取如下措施:
(1) 遠(yuǎn)離電源電纜、大容量接觸器以及其他產(chǎn)生較強(qiáng)磁場(chǎng)設(shè)備的電源線路。
(2) 在電纜間設(shè)置屏蔽導(dǎo)體,再將屏蔽導(dǎo)體接地。
