style="text-indent:25px">電流互感器工作原理：在供電用電的線路中，電流相差從幾安到幾萬安，電壓相差從幾伏到幾百萬伏。線路中電流電壓都比較高，如直接測量是非常危險的。為便于二次儀表測量需要轉(zhuǎn)換為比較統(tǒng)一的電流電壓，使用電流互感器起到變流變壓和電氣隔離的作用。顯示儀表大部分是指針式的電流電壓表，所以電流互感器的二次電流大多數(shù)是安培級的（如5等）。隨著時代發(fā)展，電量測量大多已經(jīng)達到數(shù)字化，而計算機的采樣的信號一般為毫安級（0-5V、4-20mA等）。微型電流互感器二次電流為毫安級，主要起大互感器與采樣之間的橋梁作用。微型電流互感器稱之為“儀用電流互感器”。（“儀用電流互感器”有一層含義是在實驗室使用的多電流比精密電流互感器，一般用于擴大儀表量程。）杭州電流互感器公司哪家好電流互感器他的一次繞組用粗線繞成,通常只有幾匝或幾匝。</p><div

style="text-indent:25px">通常電流互感器不論其額定電壓是多少,其二此電壓皆為100V。在不同的電壓等級電路中所用的電壓互感器不同,其電壓比是不同的,如6000/100、10000/100等。pt和ct原理上是相同的,都是利用了電磁轉(zhuǎn)換,不同的是磁路不通,pt的一-次和二次流過的磁通是相同的,兩側(cè)的電勢合匝數(shù)成正比,所以根據(jù)這個原理制作的電流互感器可以測量電壓,pt是并在要測的電壓上,次就可以感應(yīng)出相應(yīng)的電壓,電壓比和匝數(shù)比倒數(shù),ct是讓待測電流流過ct的線圈內(nèi)部,從而在二次產(chǎn)生相應(yīng)電流。</p><p style="text-indent:25px">我們知道的電流互感器是通過電磁感應(yīng)原理來工作的,電流的互感器的構(gòu)成部件分為繞組和鐵芯,它們的繞組上的匝數(shù)是經(jīng)過計算過的,通過電磁感應(yīng)原理來達到一一個測量的目的。電流互感器原理是依據(jù)電磁感應(yīng)原理的。電流互感器是由閉合的鐵心和繞組組成。它的一-次繞組匝數(shù)很少,串在需要測量的電流的線路中,因此它經(jīng)常有線路的全部電流流過,二次繞組匝數(shù)比較多,串接在測儀表和保護回路中,電流互感器在工作時,它的二次回路始終是閉合的,因此測量儀表和保護回路串聯(lián)線圈的阻抗很小,電流互感器的工作狀態(tài)接近短路。三相完全星形接線是用三臺電流互感器與三只繼電器對應(yīng)按星形連接而成。</p><div

style="text-indent:25px">電流互感器的選擇方法：1、額定一次側(cè)電流應(yīng)在運行電流的20%～120%范圍內(nèi)。2、電流互感器的額定一次電壓和運行電壓相同。3、注意使二次側(cè)負(fù)載所消耗的功率不超過電流互感器的額定容量，否則電流互感器的準(zhǔn)確等級將下降。4、根據(jù)系統(tǒng)的供電方式，選擇使用電流互感器的臺數(shù)和不同的接線方式。5、根據(jù)測量的目的和保護方式的要求，選擇電流互感器的準(zhǔn)確等級。以上這些便是電流互感器的選擇方法，當(dāng)然在實際選擇購買中，我們還要看質(zhì)量和工作場景。組合式電流互感器是將兩臺或三臺電流互感器的一次、二次繞組及鐵心和電流互感器的一、二次繞組及鐵心。上海電流互感器介紹</p><p style="text-indent:25px">電流互感器的特點：一次繞組串聯(lián)在電路中，并且匝數(shù)很少。杭州電流互感器公司哪家好</p><p style="text-indent:25px">電流互感器使用原則：電流互感器的接線應(yīng)遵守串聯(lián)原則：即一次繞阻應(yīng)與被測電路串聯(lián)，而二次繞阻則與所有儀表負(fù)載串聯(lián)。按被測電流大小，選擇合適的變比，否則誤差將增大。同時，二次側(cè)一端必須接地，以防絕緣一旦損壞時，一次側(cè)高壓竄入二次低壓側(cè)，造成人身和設(shè)備事故。二次側(cè)肯定不允許開路，因一旦開路，一次側(cè)電流I1全部成為磁化電流，引起φm和E2驟增，造成鐵心過度飽和磁化，發(fā)熱嚴(yán)重乃至燒毀線圈；同時，磁路過度飽和磁化后，使誤差增大。電流互感器在正常工作時，二次側(cè)與測量儀表和繼電器等電流線圈串聯(lián)使用，測量儀表和繼電器等電流線圈阻抗很小，二次側(cè)近似于短路。杭州電流互感器公司哪家好</p><p
