電感器(Inductor)是能夠把電能轉(zhuǎn)化為磁能而存儲(chǔ)起來(lái)的元件。電感器的結(jié)構(gòu)類似于變壓器,但只有一個(gè)繞組。電感器具有一定的電感,它只阻礙電流的變化。如果電感器在沒(méi)有電流通過(guò)的狀態(tài)下,電路接通時(shí)它將試圖阻礙電流流過(guò)它;如果電感器在有電流通過(guò)的狀態(tài)下,電路斷開(kāi)時(shí)它將試圖維持電流不變。電感器又稱扼流器、電抗器、動(dòng)態(tài)電抗器。
電感器一般由骨架、繞組、屏蔽罩、封裝材料、磁心或鐵心等組成。
1、骨架 骨架泛指繞制線圈的支架。一些體積較大的固定式電感器或可調(diào)式電感器(如振蕩線圈、阻流圈等),大多數(shù)是將漆包線(或紗包線)環(huán)繞在骨架上,再將磁心或銅心、鐵心等裝入骨架的內(nèi)腔,以提高其電感量。骨架通常是采用塑料、膠木、陶瓷制成,根據(jù)實(shí)際需要可以制成不同的形狀。小型電感器(例如色碼電感器)一般不使用骨架,而是直接將漆包線繞在磁心上??招碾姼衅鳎ㄒ卜Q脫胎線圈或空心線圈,多用于高頻電路中)不用磁心、骨架和屏蔽罩等,而是先在模具上繞好后再脫去模具,并將線圈各圈之間拉開(kāi)一定距離。
2、繞組 繞組是指具有規(guī)定功能的一組線圈,它是電感器的基本組成部分。繞組有單層和多層之分。單層繞組又有密繞(繞制時(shí)導(dǎo)線一圈挨一圈)和間繞(繞制時(shí)每圈導(dǎo)線之間均隔一定的距離)兩種形式;多層繞組有分層平繞、亂繞、蜂房式繞法等多種。
3、磁心與磁棒 磁心與磁棒一般采用鎳鋅鐵氧體(NX系列)或錳鋅鐵氧體(MX系列)等材料,它有“工”字形、柱形、帽形、“E”形、罐形等多種形狀。
4、鐵心 鐵心材料主要有硅鋼片、坡莫合金等,其外形多為“E”型。
5、屏蔽罩 為避免有些電感器在工作時(shí)產(chǎn)生的磁場(chǎng)影響其它電路及元器件正常工作,就為其增加了金屬屏幕罩(例如半導(dǎo)體收音機(jī)的振蕩線圈等)。采用屏蔽罩的電感器,會(huì)增加線圈的損耗,使Q值降低。
6、封裝材料 有些電感器(如色碼電感器、色環(huán)電感器等)繞制好后,用封裝材料將線圈和磁心等密封起來(lái)。封裝材料采用塑料或環(huán)氧樹脂等。

電感是導(dǎo)線內(nèi)通過(guò)交流電流時(shí),在導(dǎo)線的內(nèi)部周圍產(chǎn)生交變磁通,導(dǎo)線的磁通量與生產(chǎn)此磁通的電流之比。當(dāng)電感中通過(guò)直流電流時(shí),其周圍只呈現(xiàn)固定的磁力線,不隨時(shí)間而變化;
可是當(dāng)在線圈中通過(guò)交流電流時(shí),其周圍將呈現(xiàn)出隨時(shí)間而變化的磁力線。根據(jù)法拉第電磁感應(yīng)定律—磁生電來(lái)分析,變化的磁力線在線圈兩端會(huì)產(chǎn)生感應(yīng)電勢(shì),此感應(yīng)電勢(shì)相當(dāng)于一個(gè)“新電源”。當(dāng)形成閉合回路時(shí),此感應(yīng)電勢(shì)就要產(chǎn)生感應(yīng)電流。由楞次定律知道感應(yīng)電流所產(chǎn)生的磁力線總量要力圖阻止磁力線的變化的。磁力線變化來(lái)源于外加交變電源的變化,故從客觀效果看,電感線圈有阻止交流電路中電流變化的特性。電感線圈有與力學(xué)中的慣性相類似的特性,在電學(xué)上取名為“自感應(yīng)”,通常在拉開(kāi)閘刀開(kāi)關(guān)或接通閘刀開(kāi)關(guān)的瞬間,會(huì)發(fā)生火花,這自感現(xiàn)象產(chǎn)生很高的感應(yīng)電勢(shì)所造成的。
總之,當(dāng)電感線圈接到交流電源上時(shí),線圈內(nèi)部的磁力線將隨電流的交變而時(shí)刻在變化著,致使線圈產(chǎn)生電磁感應(yīng)。這種因線圈本身電流的變化而產(chǎn)生的電動(dòng)勢(shì),稱為“自感電動(dòng)勢(shì)”。由此可見(jiàn),電感量只是一個(gè)與線圈的圈數(shù)、大小形狀和介質(zhì)有關(guān)的一個(gè)參量,它是電感線圈慣性的量度而與外加電流無(wú)關(guān)。
代換原則:1、電感線圈必須原值代換(匝數(shù)相等,大小相同)。2、貼片電感只須大小相同即可,還可用0歐電阻或?qū)Ь€代換。
電感分類
自感器
當(dāng)線圈中有電流通過(guò)時(shí)候,線圈的周圍就會(huì)產(chǎn)生磁場(chǎng)。當(dāng)線圈中電流發(fā)生變化時(shí),其周圍的磁場(chǎng)也產(chǎn)生相應(yīng)的變化,此變化的磁場(chǎng)可使線圈自身產(chǎn)生感應(yīng)電動(dòng)勢(shì)(感生電動(dòng)勢(shì))(電動(dòng)勢(shì)用以表示有源元件理想電源的端電壓),這就是自感。
用導(dǎo)線繞制而成,具有一定匝數(shù),能產(chǎn)生一定自感量或互感量的電子元件,常稱為電感線圈。為增大電感值,提高品質(zhì)因數(shù),縮小體積,常加入鐵磁物質(zhì)制成的鐵芯或磁芯。電感器的基本參數(shù)有電感量、品質(zhì)因數(shù)、固有電容量、穩(wěn)定性、通過(guò)的電流和使用頻率等。由單一線圈組成的電感器稱為自感器,它的自感量又稱為自感系數(shù)。
互感器
兩個(gè)電感線圈相互靠近時(shí),一個(gè)電感線圈的磁場(chǎng)變化將影響另一個(gè)電感線圈,這種影響就是互感?;ジ械拇笮∪Q于電感線圈的自感與兩個(gè)電感線圈耦合的程度,利用此原理制成的元件叫做互感器。
