低壓電器分類

低壓電器品牌產品有很(hen)多，其(qi)結構、用(yong)途(tu)及所控(kong)制對象的(de)不(bu)(bu)(bu)同(tong)，可(ke)(ke)以有不(bu)(bu)(bu)同(tong)的(de)分類(lei)方式。按用(yong)途(tu)和(he)(he)控(kong)制對象不(bu)(bu)(bu)同(tong)，可(ke)(ke)將(jiang)低壓(ya)電(dian)(dian)(dian)器(qi)(qi)(qi)分為(wei)配(pei)電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)(qi)(qi)和(he)(he)控(kong)制電(dian)(dian)(dian)器(qi)(qi)(qi)。按操作方式不(bu)(bu)(bu)同(tong)，可(ke)(ke)將(jiang)低壓(ya)電(dian)(dian)(dian)器(qi)(qi)(qi)分為(wei)自(zi)動電(dian)(dian)(dian)器(qi)(qi)(qi)和(he)(he)手動電(dian)(dian)(dian)器(qi)(qi)(qi)。按工(gong)作原理可(ke)(ke)分為(wei)電(dian)(dian)(dian)磁式電(dian)(dian)(dian)器(qi)(qi)(qi)和(he)(he)非(fei)電(dian)(dian)(dian)量控(kong)制電(dian)(dian)(dian)器(qi)(qi)(qi)。

低壓電器的定義

低壓電(dian)(dian)器通常(chang)是指在交流電(dian)(dian)壓1200V或直流電(dian)(dian)壓1500V以下工作的(de)電(dian)(dian)器。常(chang)見的(de)低壓器有開(kai)關、熔(rong)斷器、接觸(chu)器、漏電(dian)(dian)保護(hu)器和繼(ji)電(dian)(dian)器等。

低壓電器的作用有哪些

低壓電(dian)器能夠依(yi)據操作信號或(huo)外界現(xian)場信號的要求，自動或(huo)手動地改變電(dian)路(lu)的狀態、參數(shu)，實現(xian)對電(dian)路(lu)或(huo)被控對象的控制、指示(shi)、測量、保護(hu)、調節。

低壓電器和高壓電器的主要區別

低壓電(dian)器(qi)(qi)和高壓電(dian)器(qi)(qi)最大的區別就是(shi)工(gong)作電(dian)壓的不(bu)同，其(qi)次二(er)者(zhe)的安全性也(ye)因此(ci)不(bu)同，高壓電(dian)器(qi)(qi)有更多(duo)防護。一般來說誤觸(chu)(chu)低壓電(dian)器(qi)(qi)有很大希望救命，但是(shi)誤觸(chu)(chu)高壓電(dian)器(qi)(qi)可(ke)能會(hui)當場喪命！

低壓電器原理

低(di)(di)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)(shi)一種(zhong)能(neng)根(gen)據外界(jie)的(de)信號和(he)要求，手動或自(zi)動地接通、斷開電(dian)(dian)(dian)(dian)(dian)路，以(yi)實現(xian)對電(dian)(dian)(dian)(dian)(dian)路或非電(dian)(dian)(dian)(dian)(dian)對象的(de)切換(huan)、控(kong)制(zhi)(zhi)、保護、檢測(ce)、變換(huan)和(he)調(diao)節的(de)元(yuan)件(jian)或設(she)備。控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)按其工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)高低(di)(di)，以(yi)交(jiao)流1200V、直流1500V為(wei)界(jie)，可(ke)劃分為(wei)高壓(ya)(ya)控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)和(he)低(di)(di)壓(ya)(ya)控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)兩大類。總(zong)的(de)來說(shuo)，低(di)(di)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)可(ke)以(yi)分為(wei)配電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)和(he)控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)兩大類，是(shi)(shi)成(cheng)套電(dian)(dian)(dian)(dian)(dian)氣(qi)設(she)備的(de)基本組(zu)成(cheng)元(yuan)件(jian)。在工(gong)業、農業、交(jiao)通、國防以(yi)及人(ren)們用電(dian)(dian)(dian)(dian)(dian)部(bu)門中，大多(duo)數采用低(di)(di)壓(ya)(ya)供電(dian)(dian)(dian)(dian)(dian)，因(yin)此電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)元(yuan)件(jian)的(de)質量將直接影響到低(di)(di)壓(ya)(ya)供電(dian)(dian)(dian)(dian)(dian)系統的(de)可(ke)靠性。
