低壓電器分類

低壓電器品牌產品有很(hen)多，其結構、用途及所(suo)控制(zhi)(zhi)對象的不(bu)同(tong)，可(ke)(ke)以有不(bu)同(tong)的分(fen)類方式。按(an)(an)用途和(he)控制(zhi)(zhi)對象不(bu)同(tong)，可(ke)(ke)將(jiang)低壓電(dian)(dian)(dian)器(qi)分(fen)為配電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)和(he)控制(zhi)(zhi)電(dian)(dian)(dian)器(qi)。按(an)(an)操作方式不(bu)同(tong)，可(ke)(ke)將(jiang)低壓電(dian)(dian)(dian)器(qi)分(fen)為自動電(dian)(dian)(dian)器(qi)和(he)手動電(dian)(dian)(dian)器(qi)。按(an)(an)工作原理可(ke)(ke)分(fen)為電(dian)(dian)(dian)磁式電(dian)(dian)(dian)器(qi)和(he)非電(dian)(dian)(dian)量控制(zhi)(zhi)電(dian)(dian)(dian)器(qi)。

低壓電器的定義

低(di)壓電(dian)器(qi)(qi)通(tong)常(chang)是指在交(jiao)流(liu)電(dian)壓1200V或直流(liu)電(dian)壓1500V以下工作的(de)電(dian)器(qi)(qi)。常(chang)見的(de)低(di)壓器(qi)(qi)有(you)開關、熔斷器(qi)(qi)、接觸器(qi)(qi)、漏電(dian)保護器(qi)(qi)和繼(ji)電(dian)器(qi)(qi)等(deng)。

低壓電器的作用有哪些

低壓電(dian)器能夠依據操(cao)作(zuo)信號或外界(jie)現(xian)場信號的(de)要求，自動或手(shou)動地改變電(dian)路(lu)(lu)的(de)狀態、參數，實現(xian)對(dui)電(dian)路(lu)(lu)或被控對(dui)象的(de)控制(zhi)、指示、測(ce)量、保護(hu)、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(gao)壓(ya)電(dian)(dian)器(qi)(qi)最大(da)的區別(bie)就是工作(zuo)電(dian)(dian)壓(ya)的不(bu)同，其(qi)次二(er)者(zhe)的安(an)全性(xing)也因此不(bu)同，高(gao)壓(ya)電(dian)(dian)器(qi)(qi)有更多防護。一般來說(shuo)誤觸(chu)低壓(ya)電(dian)(dian)器(qi)(qi)有很大(da)希望救命，但是誤觸(chu)高(gao)壓(ya)電(dian)(dian)器(qi)(qi)可(ke)能會當場喪命！

低壓電器原理

低(di)(di)壓電(dian)(dian)器(qi)是(shi)一種能根據外界的信號(hao)和(he)要(yao)求，手動或自動地接(jie)通(tong)、斷開電(dian)(dian)路(lu)，以(yi)實現(xian)對電(dian)(dian)路(lu)或非電(dian)(dian)對象的切換、控制(zhi)、保護、檢測、變換和(he)調節的元件(jian)(jian)或設備。控制(zhi)電(dian)(dian)器(qi)按(an)其工(gong)作電(dian)(dian)壓的高(gao)低(di)(di)，以(yi)交流1200V、直流1500V為界，可(ke)劃分為高(gao)壓控制(zhi)電(dian)(dian)器(qi)和(he)低(di)(di)壓控制(zhi)電(dian)(dian)器(qi)兩大類。總的來(lai)說，低(di)(di)壓電(dian)(dian)器(qi)可(ke)以(yi)分為配電(dian)(dian)電(dian)(dian)器(qi)和(he)控制(zhi)電(dian)(dian)器(qi)兩大類，是(shi)成套電(dian)(dian)氣設備的基(ji)本組成元件(jian)(jian)。在工(gong)業、農業、交通(tong)、國(guo)防以(yi)及人們(men)用(yong)電(dian)(dian)部門中，大多(duo)數采用(yong)低(di)(di)壓供電(dian)(dian)，因此電(dian)(dian)器(qi)元件(jian)(jian)的質量將直接(jie)影(ying)響到低(di)(di)壓供電(dian)(dian)系統的可(ke)靠性。
