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(hen)多，其結構、用途及所控(kong)制(zhi)(zhi)對象的不(bu)(bu)同(tong)(tong)(tong)，可以有(you)不(bu)(bu)同(tong)(tong)(tong)的分(fen)(fen)類方(fang)式。按用途和(he)(he)(he)(he)控(kong)制(zhi)(zhi)對象不(bu)(bu)同(tong)(tong)(tong)，可將(jiang)低壓電(dian)器(qi)分(fen)(fen)為(wei)配(pei)電(dian)電(dian)器(qi)和(he)(he)(he)(he)控(kong)制(zhi)(zhi)電(dian)器(qi)。按操作方(fang)式不(bu)(bu)同(tong)(tong)(tong)，可將(jiang)低壓電(dian)器(qi)分(fen)(fen)為(wei)自動(dong)電(dian)器(qi)和(he)(he)(he)(he)手(shou)動(dong)電(dian)器(qi)。按工作原理可分(fen)(fen)為(wei)電(dian)磁式電(dian)器(qi)和(he)(he)(he)(he)非電(dian)量(liang)控(kong)制(zhi)(zhi)電(dian)器(qi)。

低壓電器的定義

低壓(ya)電(dian)器(qi)(qi)(qi)(qi)通常是指(zhi)在交(jiao)流電(dian)壓(ya)1200V或(huo)直流電(dian)壓(ya)1500V以下工作的(de)電(dian)器(qi)(qi)(qi)(qi)。常見的(de)低壓(ya)器(qi)(qi)(qi)(qi)有開關(guan)、熔斷器(qi)(qi)(qi)(qi)、接觸器(qi)(qi)(qi)(qi)、漏(lou)電(dian)保護器(qi)(qi)(qi)(qi)和繼電(dian)器(qi)(qi)(qi)(qi)等。

低壓電器的作用有哪些

低壓電器(qi)能夠依據操作信(xin)號或外界現場(chang)信(xin)號的(de)要求，自動(dong)或手動(dong)地改(gai)變電路的(de)狀態、參數，實現對電路或被(bei)控對象的(de)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(di)壓(ya)電(dian)器(qi)(qi)(qi)和高(gao)壓(ya)電(dian)器(qi)(qi)(qi)最大(da)的區別就是工作(zuo)電(dian)壓(ya)的不(bu)同，其次二(er)者的安全(quan)性也(ye)因此不(bu)同，高(gao)壓(ya)電(dian)器(qi)(qi)(qi)有更多防護(hu)。一般(ban)來(lai)說誤觸(chu)低(di)壓(ya)電(dian)器(qi)(qi)(qi)有很大(da)希望救(jiu)命(ming)，但是誤觸(chu)高(gao)壓(ya)電(dian)器(qi)(qi)(qi)可能會當場喪(sang)命(ming)！

低壓電器原理

低(di)(di)壓電(dian)(dian)(dian)器(qi)(qi)是(shi)一種能(neng)根據外(wai)界(jie)的(de)(de)信號和(he)要求(qiu)，手(shou)動或自動地接通、斷開電(dian)(dian)(dian)路，以實現(xian)對(dui)電(dian)(dian)(dian)路或非電(dian)(dian)(dian)對(dui)象的(de)(de)切(qie)換、控(kong)制(zhi)(zhi)、保護、檢(jian)測、變換和(he)調節的(de)(de)元件(jian)或設備(bei)。控(kong)制(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)按其工(gong)作電(dian)(dian)(dian)壓的(de)(de)高(gao)低(di)(di)，以交流1200V、直流1500V為(wei)界(jie)，可(ke)劃分為(wei)高(gao)壓控(kong)制(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)和(he)低(di)(di)壓控(kong)制(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)兩大(da)類。總的(de)(de)來說，低(di)(di)壓電(dian)(dian)(dian)器(qi)(qi)可(ke)以分為(wei)配電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)(qi)和(he)控(kong)制(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)兩大(da)類，是(shi)成套電(dian)(dian)(dian)氣設備(bei)的(de)(de)基本組成元件(jian)。在工(gong)業、農業、交通、國防以及人們用電(dian)(dian)(dian)部門中，大(da)多(duo)數采用低(di)(di)壓供電(dian)(dian)(dian)，因此電(dian)(dian)(dian)器(qi)(qi)元件(jian)的(de)(de)質量將直接影響(xiang)到低(di)(di)壓供電(dian)(dian)(dian)系統(tong)的(de)(de)可(ke)靠(kao)性。
