5.作用
(1)阻流：線圈中的自感電動(dòng)勢(shì)總是與線圈中的電流變化相對(duì)抗。主要可分為高頻阻流線圈及低頻阻流線圈。
(2)調(diào)諧與選頻：電感線圈與電容器并聯(lián)可組成LC調(diào)諧電路。即電路的固有振蕩頻率f0與非交流信號(hào)的頻率f相等，則回路的感抗與容抗也相等，于是電磁能量就在電感、電容之間來(lái)回振蕩，這就是LC回路的諧振現(xiàn)象。諧振時(shí)由于電路的感抗與容抗等值又反向，因此回路總電流的感抗最小，電流量最大(指f=f0的交流信號(hào))，所以LC諧振電路具有選擇頻率的作用，能將某一頻率f的交流信號(hào)選擇出來(lái)。
(3)扼流：在低頻電路用來(lái)阻止低頻交流電;脈動(dòng)直流電到純直流電路;它常用在整流電路輸出端兩個(gè)濾波電容的中間，扼流圈與電容組成濾波電路。在高頻電路：是防止高頻電流流向低頻端，在老式再生式收音機(jī)中的高頻扼流圈得到應(yīng)用。
(4)濾波：也是阻止整流后的脈動(dòng)直流電流流向純直流電路由扼流圈(為簡(jiǎn)化電路，降低成本，用純電阻替帶扼流圈)兩個(gè)電容(電解電容)組成派式濾波電路。利用電容充放電作用和扼 流圈通直流電，阻擋交流電特性來(lái)完成平滑直流電而得到純正的直流電。
(5)震蕩：整流是把交流電變成直流電，那么震蕩就是把直流電變成交流電的反過(guò)程，因此把完成這一過(guò)程的電路叫作“震蕩器”。震蕩器的波形：有正旋波，鋸齒波，梯形波，方波，矩形波，尖峰波。頻率由幾赫茲-幾十G赫茲。在有線電，無(wú)線電領(lǐng)域應(yīng)用非常廣泛。
電感器形狀
6.檢測(cè)
電感器的常見(jiàn)故障有斷路、短路等。為了保證電路正常工作，電感器使用前必須進(jìn)行測(cè)量，用萬(wàn)用表歐姆檔可以對(duì)電感器進(jìn)行簡(jiǎn)單的測(cè)量，測(cè)出電感線圈的直流電阻，并與其技術(shù)指標(biāo)相比較：若阻值比規(guī)定的阻值小得多，則說(shuō)明線圈存在局部短路或嚴(yán)重短路情況;若阻值為∞，則表示線圈存在斷路。
7.使用注意事項(xiàng)
(1)電感使用的場(chǎng)合
潮濕與干燥、環(huán)境溫度的高低、高頻或低頻環(huán)境、要讓電感表現(xiàn)的是感性，還是阻抗特性等，都要注意。
(2)電感的頻率特性
在低頻時(shí)，電感一般呈現(xiàn)電感特性，既只起蓄能，濾高頻的特性。但在高頻時(shí)，它的阻抗特性表現(xiàn)的很明顯。有耗能發(fā)熱，感性效應(yīng)降低等現(xiàn)象。不同的電感的高頻特性都不一樣。
以上就是電感器的定義、工作原理、符號(hào)與單位、技術(shù)參數(shù)、使用注意事項(xiàng)以及在電路中的作用介紹了。電感器的種類很多，根據(jù)不同的結(jié)構(gòu)特點(diǎn)，可分為單層線圈、多層線圈、蜂房線圈、帶磁芯線圈及可變電感線圈等等，因此在選擇時(shí)，可根據(jù)使用場(chǎng)合、頻率要求等條件來(lái)決定。
