低壓電器行業簡介

低壓電器分類

低壓電器品牌產品有很多(duo)，其結構、用途及所控(kong)制對象(xiang)的(de)(de)不(bu)(bu)(bu)同，可以有不(bu)(bu)(bu)同的(de)(de)分(fen)類方(fang)式(shi)。按(an)用途和控(kong)制對象(xiang)不(bu)(bu)(bu)同，可將(jiang)(jiang)低壓電(dian)(dian)器(qi)(qi)分(fen)為配電(dian)(dian)電(dian)(dian)器(qi)(qi)和控(kong)制電(dian)(dian)器(qi)(qi)。按(an)操(cao)作方(fang)式(shi)不(bu)(bu)(bu)同，可將(jiang)(jiang)低壓電(dian)(dian)器(qi)(qi)分(fen)為自動電(dian)(dian)器(qi)(qi)和手動電(dian)(dian)器(qi)(qi)。按(an)工作原理可分(fen)為電(dian)(dian)磁(ci)式(shi)電(dian)(dian)器(qi)(qi)和非(fei)電(dian)(dian)量控(kong)制電(dian)(dian)器(qi)(qi)。

低壓電器的定義

低壓(ya)電(dian)器(qi)(qi)通常(chang)是指在交(jiao)流電(dian)壓(ya)1200V或直(zhi)流電(dian)壓(ya)1500V以下工作的電(dian)器(qi)(qi)。常(chang)見的低壓(ya)器(qi)(qi)有開關、熔斷器(qi)(qi)、接觸器(qi)(qi)、漏電(dian)保護器(qi)(qi)和(he)繼電(dian)器(qi)(qi)等。

低壓電器的作用有哪些

低壓電(dian)器能夠(gou)依據操作信(xin)號或外界(jie)現場(chang)信(xin)號的要求，自動或手動地(di)改變電(dian)路的狀態(tai)、參數，實現對電(dian)路或被控(kong)(kong)對象的控(kong)(kong)制、指示、測(ce)量、保護、調節。

低壓電器和高壓電器的主要區別

低壓電(dian)器(qi)和高壓電(dian)器(qi)最大的區別就是(shi)工(gong)作電(dian)壓的不同，其次二者的安全性也因(yin)此不同，高壓電(dian)器(qi)有(you)更多(duo)防護(hu)。一般來說(shuo)誤(wu)觸低壓電(dian)器(qi)有(you)很大希望救命，但是(shi)誤(wu)觸高壓電(dian)器(qi)可能會當場(chang)喪命！

低壓電器原理

低壓(ya)電(dian)(dian)(dian)器(qi)(qi)是(shi)一種能根據外(wai)界的(de)信號(hao)和要(yao)求，手動或自動地接通(tong)、斷開電(dian)(dian)(dian)路，以(yi)實(shi)現(xian)對(dui)電(dian)(dian)(dian)路或非(fei)電(dian)(dian)(dian)對(dui)象的(de)切換、控制(zhi)(zhi)、保護、檢測、變換和調(diao)節的(de)元件或設(she)備(bei)。控制(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)按其工作電(dian)(dian)(dian)壓(ya)的(de)高低，以(yi)交流1200V、直流1500V為界，可(ke)劃分(fen)為高壓(ya)控制(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)和低壓(ya)控制(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)兩大類(lei)。總(zong)的(de)來說，低壓(ya)電(dian)(dian)(dian)器(qi)(qi)可(ke)以(yi)分(fen)為配電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)(qi)和控制(zhi)(zhi)電(dian)(dian)(dian)器(qi)(qi)兩大類(lei)，是(shi)成套電(dian)(dian)(dian)氣設(she)備(bei)的(de)基本組成元件。在工業、農(nong)業、交通(tong)、國防以(yi)及人們用(yong)電(dian)(dian)(dian)部門中，大多數采用(yong)低壓(ya)供(gong)電(dian)(dian)(dian)，因此電(dian)(dian)(dian)器(qi)(qi)元件的(de)質量將直接影響到低壓(ya)供(gong)電(dian)(dian)(dian)系(xi)統的(de)可(ke)靠性。
