現在，我(wo)們(men)(men)周圍(wei)有(you)很多電(dian)(dian)子產(chan)品(pin)，所以我(wo)們(men)(men)將使用(yong)(yong)(yong)電(dian)(dian)感線圈。在使用(yong)(yong)(yong)它之(zhi)前，我(wo)們(men)(men)需要了解(jie)它的性能(neng)和(he)操(cao)作方法，這樣就沒有(you)問題了。我(wo)們(men)(men)應該養成在使用(yong)(yong)(yong)設(she)備之(zhi)前檢(jian)查的習(xi)慣，以便及時(shi)發現問題。今天(tian)東莞市(shi)石碣(jie)嘉德磁電(dian)(dian)制品(pin)廠家將與你(ni)一起(qi)了解(jie)電(dian)(dian)感線圈阻塞(sai)電(dian)(dian)流(liu)的作用(yong)(yong)(yong)是什么，具體(ti)如下：

　　電(dian)感線(xian)(xian)圈阻流(liu)效應:電(dian)感線(xian)(xian)路中(zhong)的(de)自感電(dian)動勢(shi)始終與線(xian)(xian)圈中(zhong)電(dian)流(liu)的(de)變化(hua)相對立。電(dian)感線(xian)(xian)圈對通(tong)信(xin)(xin)電(dian)流(liu)具有(you)阻斷作用(yong)，阻斷作用(yong)的(de)XL，單位(wei)為(wei)歐姆。電(dian)感線(xian)(xian)圈具有(you)防(fang)止通(tong)信(xin)(xin)電(dian)流(liu)的(de)作用(yong)，電(dian)感線(xian)(xian)圈具有(you)防(fang)止通(tong)信(xin)(xin)電(dian)流(liu)的(de)作用(yong)。它與電(dian)感L和通(tong)信(xin)(xin)頻率的(de)關系為(wei)XL=2MFL。

　　電(dian)(dian)(dian)(dian)感可分為(wei)高(gao)頻(pin)阻流線(xian)圈(quan)和(he)低(di)頻(pin)阻流線(xian)圈(quan)。調諧(xie)(xie)選頻(pin)效果:LC調諧(xie)(xie)電(dian)(dian)(dian)(dian)路(lu)可由電(dian)(dian)(dian)(dian)感線(xian)圈(quan)和(he)電(dian)(dian)(dian)(dian)容(rong)并聯組成。也就(jiu)是說，電(dian)(dian)(dian)(dian)路(lu)的(de)固有振(zhen)動(dong)(dong)頻(pin)率FO與非通信信號的(de)頻(pin)率F相同(tong)，那(nei)么電(dian)(dian)(dian)(dian)路(lu)的(de)電(dian)(dian)(dian)(dian)感和(he)電(dian)(dian)(dian)(dian)容(rong)也相同(tong)，因此電(dian)(dian)(dian)(dian)磁能量(liang)在電(dian)(dian)(dian)(dian)感和(he)電(dian)(dian)(dian)(dian)容(rong)中來回振(zhen)動(dong)(dong)，這就(jiu)是LC電(dian)(dian)(dian)(dian)路(lu)的(de)諧(xie)(xie)振(zhen)現象。

　　在諧振的(de)(de)(de)情況下，電(dian)(dian)路的(de)(de)(de)電(dian)(dian)感和電(dian)(dian)容等效反(fan)向(xiang)，電(dian)(dian)路總電(dian)(dian)流最小，電(dian)(dian)流最大(da)。LC諧振電(dian)(dian)路具有(you)(you)選(xuan)(xuan)擇(ze)頻(pin)率的(de)(de)(de)作(zuo)用(yong)(yong)，可以(yi)選(xuan)(xuan)擇(ze)某一(yi)頻(pin)率的(de)(de)(de)通信信號。很多工作(zuo)是不(bu)能用(yong)(yong)好壞來衡量的(de)(de)(de)，就(jiu)像這個電(dian)(dian)感線圈一(yi)樣，不(bu)能因為電(dian)(dian)感線圈有(you)(you)阻塞電(dian)(dian)流就(jiu)得出(chu)它(ta)不(bu)好的(de)(de)(de)結論。
