低壓電器分類

低壓電器品牌產品有很多，其結構、用(yong)途(tu)及所控(kong)制對象的(de)不(bu)同(tong)，可以有不(bu)同(tong)的(de)分(fen)類(lei)方(fang)式(shi)(shi)。按(an)用(yong)途(tu)和(he)(he)控(kong)制對象不(bu)同(tong)，可將(jiang)低壓(ya)電(dian)器(qi)(qi)分(fen)為(wei)配電(dian)電(dian)器(qi)(qi)和(he)(he)控(kong)制電(dian)器(qi)(qi)。按(an)操(cao)作方(fang)式(shi)(shi)不(bu)同(tong)，可將(jiang)低壓(ya)電(dian)器(qi)(qi)分(fen)為(wei)自動電(dian)器(qi)(qi)和(he)(he)手動電(dian)器(qi)(qi)。按(an)工作原(yuan)理(li)可分(fen)為(wei)電(dian)磁式(shi)(shi)電(dian)器(qi)(qi)和(he)(he)非電(dian)量控(kong)制電(dian)器(qi)(qi)。

低壓電器的定義

低(di)壓電(dian)器(qi)通常是(shi)指在交流電(dian)壓1200V或直流電(dian)壓1500V以下工(gong)作(zuo)的電(dian)器(qi)。常見的低(di)壓器(qi)有開(kai)關、熔斷器(qi)、接觸器(qi)、漏(lou)電(dian)保(bao)護器(qi)和(he)繼電(dian)器(qi)等(deng)。

低壓電器的作用有哪些

低壓電器(qi)能(neng)夠依(yi)據操作信號或外界現(xian)場(chang)信號的要求，自動或手動地改變電路的狀態、參數，實(shi)現(xian)對電路或被(bei)控對象(xiang)的控制、指示、測量、保護、調(diao)節。

低壓電器和高壓電器的主要區別

低壓(ya)電器(qi)(qi)和高壓(ya)電器(qi)(qi)最大的區別(bie)就是工(gong)作電壓(ya)的不(bu)同，其次(ci)二者的安全性也因此不(bu)同，高壓(ya)電器(qi)(qi)有更多防護。一(yi)般來說誤觸(chu)低壓(ya)電器(qi)(qi)有很大希(xi)望救(jiu)命(ming)，但是誤觸(chu)高壓(ya)電器(qi)(qi)可能會當(dang)場(chang)喪命(ming)！

低壓電器原理

低壓(ya)(ya)電(dian)(dian)(dian)器(qi)是一(yi)種能根(gen)據外界(jie)的(de)(de)(de)信號和(he)要求，手動或(huo)自動地接(jie)通(tong)、斷開電(dian)(dian)(dian)路，以實現(xian)對(dui)電(dian)(dian)(dian)路或(huo)非電(dian)(dian)(dian)對(dui)象的(de)(de)(de)切換、控(kong)制、保(bao)護、檢測、變換和(he)調節的(de)(de)(de)元件(jian)或(huo)設備。控(kong)制電(dian)(dian)(dian)器(qi)按其(qi)工作電(dian)(dian)(dian)壓(ya)(ya)的(de)(de)(de)高低，以交(jiao)(jiao)流1200V、直流1500V為界(jie)，可(ke)劃分(fen)為高壓(ya)(ya)控(kong)制電(dian)(dian)(dian)器(qi)和(he)低壓(ya)(ya)控(kong)制電(dian)(dian)(dian)器(qi)兩(liang)(liang)大類。總的(de)(de)(de)來說，低壓(ya)(ya)電(dian)(dian)(dian)器(qi)可(ke)以分(fen)為配(pei)電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)和(he)控(kong)制電(dian)(dian)(dian)器(qi)兩(liang)(liang)大類，是成套電(dian)(dian)(dian)氣設備的(de)(de)(de)基本組成元件(jian)。在工業、農業、交(jiao)(jiao)通(tong)、國防以及人們用電(dian)(dian)(dian)部門中，大多數采用低壓(ya)(ya)供(gong)電(dian)(dian)(dian)，因此電(dian)(dian)(dian)器(qi)元件(jian)的(de)(de)(de)質量(liang)將直接(jie)影響到(dao)低壓(ya)(ya)供(gong)電(dian)(dian)(dian)系統的(de)(de)(de)可(ke)靠性(xing)。
