低壓電器分類

低壓電器品牌產品有很多，其結構、用途及所控制對象的不同，可以有不同的分類方式。按用途和控制對象不同，可將低壓電器分為配電電器和控制電器。按操作方式不同，可將低壓電器分為自動電器和手動電器。按工作原理可分為電磁式電器和非電量控制電器。

低壓電器的定義

低(di)(di)壓電(dian)(dian)器(qi)通(tong)常是指在交(jiao)流電(dian)(dian)壓1200V或直流電(dian)(dian)壓1500V以下工作的電(dian)(dian)器(qi)。常見的低(di)(di)壓器(qi)有開關(guan)、熔斷器(qi)、接觸器(qi)、漏電(dian)(dian)保護器(qi)和(he)繼電(dian)(dian)器(qi)等。

低壓電器的作用有哪些

低壓電(dian)器能(neng)夠依(yi)據操作信號或外界(jie)現場信號的(de)(de)(de)要求，自動或手(shou)動地(di)改(gai)變電(dian)路的(de)(de)(de)狀(zhuang)態、參數，實現對(dui)電(dian)路或被控(kong)對(dui)象的(de)(de)(de)控(kong)制、指示、測(ce)量、保護(hu)、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)和高壓(ya)電(dian)(dian)器(qi)最大(da)的區(qu)別就是工(gong)作電(dian)(dian)壓(ya)的不同(tong)，其次二者的安全性也因(yin)此不同(tong)，高壓(ya)電(dian)(dian)器(qi)有更(geng)多(duo)防(fang)護。一般來說(shuo)誤(wu)觸低(di)壓(ya)電(dian)(dian)器(qi)有很大(da)希望救命，但是誤(wu)觸高壓(ya)電(dian)(dian)器(qi)可(ke)能會當(dang)場喪命！

低壓電器原理

低壓(ya)(ya)(ya)電(dian)(dian)器(qi)是(shi)(shi)一(yi)種能根據外界(jie)的(de)信號和要求，手動(dong)或自動(dong)地(di)接(jie)通(tong)、斷開(kai)電(dian)(dian)路，以(yi)(yi)實現對電(dian)(dian)路或非電(dian)(dian)對象的(de)切換、控(kong)(kong)制(zhi)(zhi)、保護(hu)、檢測(ce)、變換和調節的(de)元件(jian)或設(she)備。控(kong)(kong)制(zhi)(zhi)電(dian)(dian)器(qi)按其工(gong)作電(dian)(dian)壓(ya)(ya)(ya)的(de)高低，以(yi)(yi)交(jiao)流1200V、直流1500V為(wei)界(jie)，可劃分(fen)為(wei)高壓(ya)(ya)(ya)控(kong)(kong)制(zhi)(zhi)電(dian)(dian)器(qi)和低壓(ya)(ya)(ya)控(kong)(kong)制(zhi)(zhi)電(dian)(dian)器(qi)兩(liang)大類(lei)。總的(de)來說，低壓(ya)(ya)(ya)電(dian)(dian)器(qi)可以(yi)(yi)分(fen)為(wei)配電(dian)(dian)電(dian)(dian)器(qi)和控(kong)(kong)制(zhi)(zhi)電(dian)(dian)器(qi)兩(liang)大類(lei)，是(shi)(shi)成套電(dian)(dian)氣(qi)設(she)備的(de)基本組成元件(jian)。在(zai)工(gong)業(ye)、農業(ye)、交(jiao)通(tong)、國防以(yi)(yi)及人(ren)們(men)用(yong)電(dian)(dian)部門中，大多數(shu)采用(yong)低壓(ya)(ya)(ya)供電(dian)(dian)，因此電(dian)(dian)器(qi)元件(jian)的(de)質(zhi)量將直接(jie)影(ying)響到低壓(ya)(ya)(ya)供電(dian)(dian)系統的(de)可靠性。
