style="text-indent:25px">鐵氧體抗干擾磁心是近幾年發(fā)展起來的新型的價廉物美的干擾壓制器件，其作用相當(dāng)于低通濾波器，較好地解決了電源線，信號線和連接器的高頻干擾壓制問題，而且具有使用簡單，方便，有效，占用空間不大等一系列優(yōu)點，用鐵氧體抗干擾磁心來壓制電磁干擾(EMI)是經(jīng)濟(jì)簡便而有效的方法，已普遍應(yīng)用于計算機(jī)等各種**或民用電子設(shè)備。鐵氧體是一種利用高導(dǎo)磁性材料滲合其他一種或多種鎂、鋅、鎳等金屬在2000℃燒聚而成。在低頻段，鐵氧體抗干擾磁心呈現(xiàn)出非常低的感性阻抗值，不影響數(shù)據(jù)線或信號線上有用信號的傳輸。而在高頻段，從10MHz左右開始，阻抗增大，其感抗分量仍保持很小，電阻性分量卻迅速增加，當(dāng)有高頻能量穿過磁性材料時，電阻性分量就會把這些能量轉(zhuǎn)化為熱能耗散掉。這樣就構(gòu)成一個低通濾波器，使高頻噪音信號有大的衰減，而對低頻有用信號的阻抗可以忽略，不影響電路的正常工作。寧波呼吸機(jī)磁環(huán)哪家好電腦機(jī)箱內(nèi)的主板、CPU、電源、及IDE數(shù)據(jù)線都工作于很高的頻率狀態(tài)下。</p><div

style="text-indent:25px">導(dǎo)致鐵氧體磁環(huán)發(fā)熱的原因：純鐵的居里點高達(dá)770攝氏度，可見羰基鐵粉芯材料對發(fā)熱的承受能力遠(yuǎn)高于鎳鋅鐵氧體，這也是羰基鐵粉芯材料更加適合高頻大功率場合的一個原因。磁芯和線圈發(fā)熱主要是因為磁芯截面積太小、磁飽和等原因，也可能是工作頻率太高。磁環(huán)不宜直接繞制逆變變壓器，較好使用EE、EI等磁芯，因為磁環(huán)磁路中沒有氣隙，磁阻小，很容易導(dǎo)致磁感應(yīng)強(qiáng)度過大而飽和，一旦磁飽和，線圈電感會急劇下降，電流也會急劇增大，就容易導(dǎo)致嚴(yán)重的發(fā)熱。但如果某些振蕩是基于磁飽和原理而振蕩的(例如電子鎮(zhèn)流器電路)，就必須用磁環(huán)。如果是驅(qū)動場管燙手，更要高度懷疑是否磁芯已經(jīng)飽和導(dǎo)致電流過大。</p><p style="text-indent:25px">電機(jī)磁環(huán)的應(yīng)用：一、電機(jī)磁環(huán)對和構(gòu)成的吸收濾波器，除了應(yīng)選用高磁導(dǎo)率的有耗材料外，它們在線路中對高頻成分所呈現(xiàn)的電阻大約是十至幾百，因此它在高阻抗電路中的作用并不明顯，相反，在低阻抗電路(如功率分配、電源或射頻電路)中使用將非常有效。二、電機(jī)磁環(huán)在高頻段(大于10MHz)，感抗仍然保持很小，而阻抗很大，使得高頻信號的能量穿過磁性材料時，轉(zhuǎn)換成熱量散發(fā)出去，從阻礙了高頻信號的通過，壓制了高頻信號的干擾，通常較佳壓制頻率范圍跟鐵氧體壓制元件有關(guān)，通常磁導(dǎo)率越高，壓制頻率越低，鐵氧體體積越大，壓制效果也越好，體積一定時，長而細(xì)的比短而粗的壓制效果好內(nèi)勁越小壓制效果也越好。在電子行業(yè)當(dāng)中，相信大家都知道變頻器是一種常見的干擾問題。</p><div
