style="text-indent:25px">我們平時在電子設備的電源線或信號線一端或者兩端看到的磁環(huán)就是共模扼流圈。共模扼流圈能夠對共模干擾電流形成較大的阻抗，而對差模信號沒有影響（工作信號為差模信號），因此使用簡單而不用考慮信號失真問題。并且共模扼流圈不需要接地，可以直接加到電纜上。aTJ安規(guī)與電磁兼容網。磁環(huán)的匝數(shù)選擇aTJ安規(guī)與電磁兼容網。將整束電纜穿過一個鐵氧體磁環(huán)就構成了一個共模扼流圈，根據(jù)需要，也可以將電纜在磁環(huán)上面繞幾匝。匝數(shù)越多，對頻率較低的干擾壓制效果越好，而對頻率較高的噪聲壓制作用較弱。在實際工程中，要根據(jù)干擾電流的頻率特點來調整磁環(huán)的匝數(shù)。通常當干擾信號的頻帶較寬時，可在電纜上套兩個磁環(huán)，每個磁環(huán)繞不同的匝數(shù)，這樣可以同時壓制高頻干擾和低頻干擾。蘇州汽車醫(yī)療設備磁環(huán)直銷廠家隨著現(xiàn)代化高科技的進步，越來越多的新型電子設備，不段浮出水面。</p><div

style="text-indent:25px">電機磁環(huán)的相關知識：1、增加穿過磁環(huán)的匝數(shù)可以增加低頻的阻抗，所以在很多應用中，通過繞更多的匝數(shù)，可以有效的提高阻抗，達到需要的效果。但是由于寄生電容增加，高頻的阻抗會減小。當需要壓制的干擾頻帶較寬時，可在兩個電機磁環(huán)上繞不同的匝數(shù)。2、增加電機磁環(huán)的個數(shù)，可以增加低頻的阻抗，但高頻的阻抗會減小。3、電機磁環(huán)安裝時要盡量靠近干擾源。4、由于電機磁環(huán)的效果取決于電路的阻抗，電路的阻抗越低，則電機磁環(huán)的效果越明顯。因此當原來的電纜兩端安裝了電容式濾波連接器時，其阻抗很低，電機磁環(huán)的效果也更明顯。</p><p style="text-indent:25px">鐵氧體材料為鐵鎂合金或鐵鎳合金，它的制造工藝和機械性能與陶瓷相似，顏色為灰黑色。電磁干擾濾波器中經常使用的一類磁芯就是鐵氧體材料，許多廠商都提供專門用于電磁干擾壓制的鐵氧體材料。這種材料的特點是高頻損耗非常大，具有很高的導磁率，他可以是電感的線圈繞組之間在高頻高阻的情況下產生的電容較小。對于壓制電磁干擾用的鐵氧體，較重要的性能參數(shù)為磁導率μ和飽和磁通密度Bs。磁導率μ可以表示為復數(shù)，實數(shù)部分構成電感，虛數(shù)部分表示損耗，隨著頻率的增加而增加。因此，它的等效電路為由電感L和電阻R組成的串聯(lián)電路，L和R都是頻率的函數(shù)。當導線穿過這種鐵氧體磁芯時，所構成的電感阻抗在形式上是隨著頻率的升高而增加，但是在不同頻率時其機理是完全不同的。這種磁環(huán)的性能不好。因為它經歷了一次燒結，所以第二次燒結會燒壞磁環(huán)的阻抗。</p><div

style="text-indent:25px">許多人添加氧化鎂或再生材料以降低成本。徐州汽車磁環(huán)報價</p><p style="text-indent:25px">導致鐵氧體磁環(huán)發(fā)熱的原因：純鐵的居里點高達770攝氏度，可見羰基鐵粉芯材料對發(fā)熱的承受能力遠高于鎳鋅鐵氧體，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，很容易導致磁感應強度過大而飽和，一旦磁飽和，線圈電感會急劇下降，電流也會急劇增大，就容易導致嚴重的發(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)。如果是驅動場管燙手，更要高度懷疑是否磁芯已經飽和導致電流過大。徐州汽車磁環(huán)報價</p><p
