低壓電器分類

低壓電器品牌產品有(you)很(hen)多(duo)，其結(jie)構、用途及所控制對象的(de)(de)不(bu)同，可(ke)以有(you)不(bu)同的(de)(de)分(fen)(fen)類(lei)方式。按用途和控制對象不(bu)同，可(ke)將低(di)壓(ya)電(dian)(dian)器(qi)(qi)(qi)分(fen)(fen)為(wei)配電(dian)(dian)電(dian)(dian)器(qi)(qi)(qi)和控制電(dian)(dian)器(qi)(qi)(qi)。按操(cao)作方式不(bu)同，可(ke)將低(di)壓(ya)電(dian)(dian)器(qi)(qi)(qi)分(fen)(fen)為(wei)自動(dong)電(dian)(dian)器(qi)(qi)(qi)和手動(dong)電(dian)(dian)器(qi)(qi)(qi)。按工作原理可(ke)分(fen)(fen)為(wei)電(dian)(dian)磁式電(dian)(dian)器(qi)(qi)(qi)和非電(dian)(dian)量控制電(dian)(dian)器(qi)(qi)(qi)。

低壓電器的定義

低壓電(dian)器(qi)通(tong)常是指(zhi)在交流電(dian)壓1200V或直流電(dian)壓1500V以下工(gong)作的電(dian)器(qi)。常見的低壓器(qi)有開(kai)關、熔(rong)斷器(qi)、接觸器(qi)、漏電(dian)保(bao)護(hu)器(qi)和繼電(dian)器(qi)等。

低壓電器的作用有哪些

低壓電器能夠依據操作(zuo)信號(hao)或外界現(xian)場信號(hao)的要求，自(zi)動或手(shou)動地(di)改(gai)變電路的狀(zhuang)態、參數，實現(xian)對(dui)電路或被控對(dui)象的控制、指示、測量、保護、調節。

低壓電器和高壓電器的主要區別

低(di)壓電(dian)器和高壓電(dian)器最大的區別就是工作(zuo)電(dian)壓的不同，其次二者的安全性也因(yin)此不同，高壓電(dian)器有更多防(fang)護。一(yi)般來說誤觸(chu)低(di)壓電(dian)器有很(hen)大希望救命，但是誤觸(chu)高壓電(dian)器可能會當場喪命！

低壓電器原理

低(di)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)器是一(yi)種(zhong)能根據(ju)外(wai)界(jie)的(de)(de)信號和(he)要求，手動(dong)(dong)或(huo)(huo)自動(dong)(dong)地接通、斷(duan)開(kai)電(dian)(dian)(dian)(dian)路，以(yi)實現對(dui)電(dian)(dian)(dian)(dian)路或(huo)(huo)非電(dian)(dian)(dian)(dian)對(dui)象的(de)(de)切換(huan)、控制、保(bao)護、檢(jian)測(ce)、變換(huan)和(he)調節的(de)(de)元(yuan)(yuan)件或(huo)(huo)設備(bei)。控制電(dian)(dian)(dian)(dian)器按其工(gong)作電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)高(gao)(gao)低(di)，以(yi)交(jiao)流1200V、直流1500V為(wei)界(jie)，可劃(hua)分(fen)為(wei)高(gao)(gao)壓(ya)(ya)(ya)控制電(dian)(dian)(dian)(dian)器和(he)低(di)壓(ya)(ya)(ya)控制電(dian)(dian)(dian)(dian)器兩大(da)類。總的(de)(de)來說，低(di)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)器可以(yi)分(fen)為(wei)配電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)器和(he)控制電(dian)(dian)(dian)(dian)器兩大(da)類，是成套(tao)電(dian)(dian)(dian)(dian)氣設備(bei)的(de)(de)基(ji)本組(zu)成元(yuan)(yuan)件。在工(gong)業、農(nong)業、交(jiao)通、國防以(yi)及人們用電(dian)(dian)(dian)(dian)部門中，大(da)多數采用低(di)壓(ya)(ya)(ya)供(gong)電(dian)(dian)(dian)(dian)，因(yin)此電(dian)(dian)(dian)(dian)器元(yuan)(yuan)件的(de)(de)質量將直接影(ying)響(xiang)到低(di)壓(ya)(ya)(ya)供(gong)電(dian)(dian)(dian)(dian)系統的(de)(de)可靠性。
