電磁干擾問(wèn)題分析及解決方法
由于用戶已試用了一臺(tái)變頻器,根據(jù)更換皮帶輪,調(diào)整電機(jī)轉(zhuǎn)速,對(duì)用變頻器節(jié)能已有一定的認(rèn)識(shí),因此決定安裝我公司的變頻器,以實(shí)現(xiàn)節(jié)能增效的目的。
我們?cè)诘谝淮伟惭b變頻器時(shí),由于未考慮到電磁兼容的嚴(yán)重性,變頻器開(kāi)機(jī)后干擾原控制系統(tǒng),在微機(jī)上多臺(tái)發(fā)酵罐發(fā)出報(bào)警信號(hào),后來(lái)加了輸入、輸出電抗器,也沒(méi)能解決問(wèn)題。后來(lái)我們觀察用戶原應(yīng)用的變頻器,他采用了濟(jì)南菲奧特電子設(shè)備有限公司生產(chǎn)的變頻器輸入端及輸出端專用電源濾波器,已正常運(yùn)行一年,于是制藥廠建議我公司購(gòu)買該類同型號(hào)的電源濾波器。
變頻器輸入端電源濾波器是采用高導(dǎo)磁率的鐵氧體磁心及鐵粉芯,配接一定的電容,構(gòu)成LC濾波器,將變頻器產(chǎn)生的高次諧波(在某一頻帶內(nèi)的)濾掉,而使臨近或同一電網(wǎng)工作的電器設(shè)備不受干擾,能夠正常工作。
