低壓電器分類
低壓電器品牌產品有(you)很多,其結構、用途(tu)及所控制(zhi)對象(xiang)的不(bu)同,可以有(you)不(bu)同的分類方(fang)式。按用途(tu)和(he)(he)控制(zhi)對象(xiang)不(bu)同,可將低(di)壓電(dian)器(qi)(qi)(qi)(qi)分為配電(dian)電(dian)器(qi)(qi)(qi)(qi)和(he)(he)控制(zhi)電(dian)器(qi)(qi)(qi)(qi)。按操作方(fang)式不(bu)同,可將低(di)壓電(dian)器(qi)(qi)(qi)(qi)分為自動(dong)電(dian)器(qi)(qi)(qi)(qi)和(he)(he)手動(dong)電(dian)器(qi)(qi)(qi)(qi)。按工作原(yuan)理(li)可分為電(dian)磁式電(dian)器(qi)(qi)(qi)(qi)和(he)(he)非電(dian)量控制(zhi)電(dian)器(qi)(qi)(qi)(qi)。
低壓電器的定義
低(di)壓電器(qi)通常是指在交流電壓1200V或直(zhi)流電壓1500V以下工作的電器(qi)。常見的低(di)壓器(qi)有開關(guan)、熔斷器(qi)、接觸器(qi)、漏(lou)電保(bao)護器(qi)和繼電器(qi)等。
低壓電器的作用有哪些
低壓電器能夠依據操作信(xin)號或外界現場信(xin)號的要求(qiu),自動或手(shou)動地改變(bian)電路的狀態、參數,實現對電路或被控對象的控制(zhi)、指示、測量(liang)、保護、調節。
低壓電器和高壓電器的主要區別
低(di)壓(ya)電(dian)(dian)器(qi)(qi)(qi)和高壓(ya)電(dian)(dian)器(qi)(qi)(qi)最大(da)的區別(bie)就是工作電(dian)(dian)壓(ya)的不同(tong),其(qi)次二者的安(an)全性(xing)也因(yin)此不同(tong),高壓(ya)電(dian)(dian)器(qi)(qi)(qi)有更多防護。一(yi)般來說誤(wu)觸(chu)低(di)壓(ya)電(dian)(dian)器(qi)(qi)(qi)有很大(da)希(xi)望(wang)救命,但(dan)是誤(wu)觸(chu)高壓(ya)電(dian)(dian)器(qi)(qi)(qi)可能(neng)會當場喪命!
低壓電器原理
低(di)壓電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)是一種能根據外界(jie)的(de)信號和要求(qiu),手動或(huo)自動地接通(tong)、斷開電(dian)(dian)路(lu)(lu),以(yi)實現對(dui)電(dian)(dian)路(lu)(lu)或(huo)非(fei)電(dian)(dian)對(dui)象的(de)切換(huan)、控制、保(bao)護、檢(jian)測、變換(huan)和調節的(de)元(yuan)件(jian)或(huo)設(she)備。控制電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)按(an)其(qi)工(gong)作電(dian)(dian)壓的(de)高低(di),以(yi)交流1200V、直流1500V為(wei)界(jie),可(ke)劃分(fen)為(wei)高壓控制電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)和低(di)壓控制電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)兩(liang)大(da)類。總的(de)來說,低(di)壓電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)可(ke)以(yi)分(fen)為(wei)配電(dian)(dian)電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)和控制電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)兩(liang)大(da)類,是成套(tao)電(dian)(dian)氣設(she)備的(de)基本組成元(yuan)件(jian)。在工(gong)業(ye)、農業(ye)、交通(tong)、國防以(yi)及人們(men)用電(dian)(dian)部(bu)門(men)中(zhong),大(da)多(duo)數采(cai)用低(di)壓供電(dian)(dian),因此電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)元(yuan)件(jian)的(de)質量將(jiang)直接影響到低(di)壓供電(dian)(dian)系統的(de)可(ke)靠性。
