低壓電器分類

低壓電器品牌產品有很(hen)多，其結構、用(yong)途及所控制對象的(de)不(bu)(bu)(bu)同，可(ke)以(yi)有不(bu)(bu)(bu)同的(de)分(fen)(fen)類(lei)方式。按用(yong)途和控制對象不(bu)(bu)(bu)同，可(ke)將低(di)壓電(dian)(dian)器(qi)分(fen)(fen)為配電(dian)(dian)電(dian)(dian)器(qi)和控制電(dian)(dian)器(qi)。按操作方式不(bu)(bu)(bu)同，可(ke)將低(di)壓電(dian)(dian)器(qi)分(fen)(fen)為自(zi)動(dong)電(dian)(dian)器(qi)和手動(dong)電(dian)(dian)器(qi)。按工作原理可(ke)分(fen)(fen)為電(dian)(dian)磁式電(dian)(dian)器(qi)和非電(dian)(dian)量控制電(dian)(dian)器(qi)。

低壓電器的定義

低(di)壓電(dian)器(qi)通常是指在交(jiao)流電(dian)壓1200V或(huo)直流電(dian)壓1500V以下工(gong)作的電(dian)器(qi)。常見的低(di)壓器(qi)有開關(guan)、熔斷器(qi)、接觸器(qi)、漏電(dian)保(bao)護器(qi)和繼電(dian)器(qi)等。

低壓電器的作用有哪些

低壓(ya)電器能夠(gou)依(yi)據(ju)操作信號(hao)或外(wai)界現場信號(hao)的(de)(de)要求，自動或手動地(di)改變(bian)電路的(de)(de)狀態、參(can)數，實現對電路或被控(kong)對象的(de)(de)控(kong)制(zhi)、指示、測量、保護、調節。

低壓電器和高壓電器的主要區別

低(di)(di)壓(ya)電(dian)器(qi)(qi)(qi)和高(gao)壓(ya)電(dian)器(qi)(qi)(qi)最大的(de)區別就是工(gong)作電(dian)壓(ya)的(de)不同，其次二者的(de)安全性也因此(ci)不同，高(gao)壓(ya)電(dian)器(qi)(qi)(qi)有(you)更多(duo)防護。一般來說誤觸(chu)(chu)低(di)(di)壓(ya)電(dian)器(qi)(qi)(qi)有(you)很大希望救命，但是誤觸(chu)(chu)高(gao)壓(ya)電(dian)器(qi)(qi)(qi)可能會當場喪命！

低壓電器原理

低(di)(di)(di)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)器是(shi)一種能根據外界的信號和要求，手(shou)動(dong)或(huo)自動(dong)地接通、斷開電(dian)(dian)(dian)(dian)(dian)路，以(yi)(yi)實現(xian)對電(dian)(dian)(dian)(dian)(dian)路或(huo)非電(dian)(dian)(dian)(dian)(dian)對象(xiang)的切換(huan)、控(kong)(kong)制(zhi)(zhi)、保護、檢測、變(bian)換(huan)和調節(jie)的元(yuan)件(jian)(jian)或(huo)設備(bei)。控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)器按(an)其工作電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的高低(di)(di)(di)，以(yi)(yi)交(jiao)流1200V、直(zhi)流1500V為界，可(ke)劃分為高壓(ya)(ya)控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)器和低(di)(di)(di)壓(ya)(ya)控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)器兩大(da)類。總的來說，低(di)(di)(di)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)器可(ke)以(yi)(yi)分為配電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)器和控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)器兩大(da)類，是(shi)成(cheng)套(tao)電(dian)(dian)(dian)(dian)(dian)氣設備(bei)的基本組(zu)成(cheng)元(yuan)件(jian)(jian)。在(zai)工業(ye)、農業(ye)、交(jiao)通、國防以(yi)(yi)及人(ren)們用(yong)電(dian)(dian)(dian)(dian)(dian)部門中，大(da)多(duo)數(shu)采(cai)用(yong)低(di)(di)(di)壓(ya)(ya)供電(dian)(dian)(dian)(dian)(dian)，因此電(dian)(dian)(dian)(dian)(dian)器元(yuan)件(jian)(jian)的質(zhi)量將(jiang)直(zhi)接影響到低(di)(di)(di)壓(ya)(ya)供電(dian)(dian)(dian)(dian)(dian)系統的可(ke)靠性。
