低壓電器行業簡介

低壓電器分類

低壓電器品牌產品有(you)很多，其(qi)結構、用途及所控(kong)(kong)制(zhi)(zhi)對(dui)象的不(bu)同(tong)(tong)，可(ke)(ke)以有(you)不(bu)同(tong)(tong)的分(fen)類(lei)方(fang)式(shi)(shi)。按用途和(he)(he)控(kong)(kong)制(zhi)(zhi)對(dui)象不(bu)同(tong)(tong)，可(ke)(ke)將(jiang)低壓(ya)電(dian)器分(fen)為(wei)配電(dian)電(dian)器和(he)(he)控(kong)(kong)制(zhi)(zhi)電(dian)器。按操作方(fang)式(shi)(shi)不(bu)同(tong)(tong)，可(ke)(ke)將(jiang)低壓(ya)電(dian)器分(fen)為(wei)自動電(dian)器和(he)(he)手動電(dian)器。按工作原理(li)可(ke)(ke)分(fen)為(wei)電(dian)磁式(shi)(shi)電(dian)器和(he)(he)非(fei)電(dian)量控(kong)(kong)制(zhi)(zhi)電(dian)器。

低壓電器的定義

低壓電(dian)器(qi)通常是指在(zai)交流電(dian)壓1200V或直流電(dian)壓1500V以下工作(zuo)的電(dian)器(qi)。常見的低壓器(qi)有開關、熔(rong)斷器(qi)、接觸器(qi)、漏(lou)電(dian)保護器(qi)和繼電(dian)器(qi)等。

低壓電器的作用有哪些

低壓電(dian)器能夠依據操作信(xin)號或(huo)外(wai)界現場信(xin)號的要(yao)求，自動或(huo)手動地改(gai)變電(dian)路的狀態、參(can)數(shu)，實現對電(dian)路或(huo)被控對象的控制、指示、測量、保護、調節。

低壓電器和高壓電器的主要區別

低壓(ya)電(dian)(dian)器(qi)(qi)和高壓(ya)電(dian)(dian)器(qi)(qi)最大(da)的區別就是工作電(dian)(dian)壓(ya)的不(bu)同，其(qi)次二者的安全性也因此不(bu)同，高壓(ya)電(dian)(dian)器(qi)(qi)有更多防護。一般來說(shuo)誤(wu)觸(chu)低壓(ya)電(dian)(dian)器(qi)(qi)有很(hen)大(da)希望救命，但是誤(wu)觸(chu)高壓(ya)電(dian)(dian)器(qi)(qi)可(ke)能會當場喪命！

低壓電器原理

低壓(ya)電(dian)(dian)(dian)器(qi)是(shi)(shi)一種能(neng)根據外界的(de)(de)信號(hao)和(he)要求(qiu)，手動或自(zi)動地接通(tong)、斷開(kai)電(dian)(dian)(dian)路(lu)，以(yi)實現對電(dian)(dian)(dian)路(lu)或非電(dian)(dian)(dian)對象(xiang)的(de)(de)切換、控制、保護、檢測、變換和(he)調節的(de)(de)元件(jian)或設備(bei)。控制電(dian)(dian)(dian)器(qi)按其工作電(dian)(dian)(dian)壓(ya)的(de)(de)高(gao)低，以(yi)交(jiao)流(liu)1200V、直流(liu)1500V為(wei)界，可劃(hua)分(fen)為(wei)高(gao)壓(ya)控制電(dian)(dian)(dian)器(qi)和(he)低壓(ya)控制電(dian)(dian)(dian)器(qi)兩大(da)類。總的(de)(de)來說(shuo)，低壓(ya)電(dian)(dian)(dian)器(qi)可以(yi)分(fen)為(wei)配電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)和(he)控制電(dian)(dian)(dian)器(qi)兩大(da)類，是(shi)(shi)成套電(dian)(dian)(dian)氣設備(bei)的(de)(de)基本(ben)組成元件(jian)。在(zai)工業、農業、交(jiao)通(tong)、國防以(yi)及人(ren)們用電(dian)(dian)(dian)部門中，大(da)多數(shu)采(cai)用低壓(ya)供(gong)電(dian)(dian)(dian)，因此電(dian)(dian)(dian)器(qi)元件(jian)的(de)(de)質量將直接影響到低壓(ya)供(gong)電(dian)(dian)(dian)系統(tong)的(de)(de)可靠(kao)性。
