低壓電器分類

低壓電器品牌產品有很多，其結(jie)構、用(yong)(yong)途(tu)(tu)及所控(kong)制(zhi)(zhi)(zhi)對(dui)象的(de)不同，可以(yi)有不同的(de)分類方式。按(an)用(yong)(yong)途(tu)(tu)和控(kong)制(zhi)(zhi)(zhi)對(dui)象不同，可將(jiang)低壓電(dian)(dian)(dian)器(qi)(qi)分為配(pei)電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)(qi)和控(kong)制(zhi)(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)。按(an)操作方式不同，可將(jiang)低壓電(dian)(dian)(dian)器(qi)(qi)分為自動(dong)(dong)電(dian)(dian)(dian)器(qi)(qi)和手動(dong)(dong)電(dian)(dian)(dian)器(qi)(qi)。按(an)工作原理可分為電(dian)(dian)(dian)磁式電(dian)(dian)(dian)器(qi)(qi)和非電(dian)(dian)(dian)量控(kong)制(zhi)(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)。

低壓電器的定義

低(di)壓(ya)電(dian)(dian)器通常是指在交流(liu)電(dian)(dian)壓(ya)1200V或直(zhi)流(liu)電(dian)(dian)壓(ya)1500V以下工作(zuo)的(de)電(dian)(dian)器。常見的(de)低(di)壓(ya)器有(you)開關、熔斷器、接觸器、漏電(dian)(dian)保護器和繼電(dian)(dian)器等。

低壓電器的作用有哪些

低壓電(dian)器能(neng)夠依據(ju)操作信號或(huo)外界現場信號的要求，自動或(huo)手動地改(gai)變(bian)電(dian)路(lu)的狀(zhuang)態、參數，實現對電(dian)路(lu)或(huo)被(bei)控對象的控制(zhi)、指示、測(ce)量、保(bao)護、調節。

低壓電器和高壓電器的主要區別

低(di)壓電(dian)(dian)器和高(gao)壓電(dian)(dian)器最大的(de)區別就是工作電(dian)(dian)壓的(de)不同，其(qi)次二(er)者的(de)安全性(xing)也因此不同，高(gao)壓電(dian)(dian)器有更多(duo)防護(hu)。一般(ban)來(lai)說(shuo)誤觸低(di)壓電(dian)(dian)器有很大希望救命，但是誤觸高(gao)壓電(dian)(dian)器可能會當場喪命！

低壓電器原理

低壓(ya)(ya)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)是一(yi)種能(neng)根據外界(jie)的(de)(de)(de)信號和(he)(he)要求(qiu)，手動或(huo)自動地(di)接通、斷(duan)開電(dian)(dian)(dian)路，以(yi)實現(xian)對電(dian)(dian)(dian)路或(huo)非(fei)電(dian)(dian)(dian)對象的(de)(de)(de)切換、控制(zhi)(zhi)、保護(hu)、檢(jian)測、變換和(he)(he)調節的(de)(de)(de)元(yuan)件(jian)(jian)或(huo)設備。控制(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)按其工作(zuo)電(dian)(dian)(dian)壓(ya)(ya)的(de)(de)(de)高低，以(yi)交(jiao)流(liu)1200V、直流(liu)1500V為(wei)界(jie)，可(ke)劃分為(wei)高壓(ya)(ya)控制(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)和(he)(he)低壓(ya)(ya)控制(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)兩大類。總的(de)(de)(de)來說，低壓(ya)(ya)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)可(ke)以(yi)分為(wei)配電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)和(he)(he)控制(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)兩大類，是成套(tao)電(dian)(dian)(dian)氣設備的(de)(de)(de)基本組成元(yuan)件(jian)(jian)。在工業、農業、交(jiao)通、國(guo)防(fang)以(yi)及人們用電(dian)(dian)(dian)部(bu)門(men)中，大多數采(cai)用低壓(ya)(ya)供電(dian)(dian)(dian)，因此電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)元(yuan)件(jian)(jian)的(de)(de)(de)質量將直接影響到低壓(ya)(ya)供電(dian)(dian)(dian)系(xi)統的(de)(de)(de)可(ke)靠(kao)性。
