描述
給變頻器輸入加裝EMI濾波器,可以有效抑制變頻器對電網(wǎng)的傳導(dǎo)干擾,加裝輸入交流和直流電抗器L1、L2,可以提高功率因數(shù),減小諧波污染,綜合效果好。在某些電機與變頻器之間距離超過100m的場合,需要在變頻器側(cè)添加交流輸出電抗器L3,解決因為輸出導(dǎo)線對地分布參數(shù)造成的漏電流保護和減少對外部的輻射干擾。一個行之有效的方法就是采用鋼管穿線或者屏蔽電纜的方法,并將鋼管外殼或者電纜屏蔽層與大地可靠連接。請注意,在不添加交流輸出電抗器L3時,如果采用鋼管穿線或者屏蔽電纜的方法,增大了輸出對地的分布電容,容易出現(xiàn)過流。當(dāng)然在實際中一般只采取其中的一種或者幾種方法。
