低壓電器分類

低壓電器品牌產品有(you)很多(duo)，其結構(gou)、用途及所控制(zhi)對象的(de)不同，可(ke)以有(you)不同的(de)分(fen)類(lei)方式。按(an)(an)用途和(he)控制(zhi)對象不同，可(ke)將(jiang)低壓電(dian)(dian)(dian)器分(fen)為(wei)配電(dian)(dian)(dian)電(dian)(dian)(dian)器和(he)控制(zhi)電(dian)(dian)(dian)器。按(an)(an)操作(zuo)方式不同，可(ke)將(jiang)低壓電(dian)(dian)(dian)器分(fen)為(wei)自動電(dian)(dian)(dian)器和(he)手(shou)動電(dian)(dian)(dian)器。按(an)(an)工作(zuo)原理(li)可(ke)分(fen)為(wei)電(dian)(dian)(dian)磁式電(dian)(dian)(dian)器和(he)非電(dian)(dian)(dian)量控制(zhi)電(dian)(dian)(dian)器。

低壓電器的定義

低壓(ya)(ya)電(dian)器(qi)通常是指在(zai)交流電(dian)壓(ya)(ya)1200V或直流電(dian)壓(ya)(ya)1500V以(yi)下工作的電(dian)器(qi)。常見(jian)的低壓(ya)(ya)器(qi)有開關、熔斷(duan)器(qi)、接觸器(qi)、漏電(dian)保護器(qi)和繼(ji)電(dian)器(qi)等。

低壓電器的作用有哪些

低壓電器能夠依據操作信號(hao)或(huo)(huo)外(wai)界現(xian)場信號(hao)的(de)要求，自動(dong)或(huo)(huo)手動(dong)地改變電路的(de)狀態、參(can)數，實現(xian)對電路或(huo)(huo)被控對象的(de)控制、指示、測量、保護(hu)、調節。

低壓電器和高壓電器的主要區別

低壓(ya)電器(qi)(qi)和高壓(ya)電器(qi)(qi)最大的(de)區別就(jiu)是(shi)工作電壓(ya)的(de)不同，其次二者的(de)安全性也因此不同，高壓(ya)電器(qi)(qi)有更多防護(hu)。一般來說誤(wu)觸低壓(ya)電器(qi)(qi)有很(hen)大希望救命(ming)，但是(shi)誤(wu)觸高壓(ya)電器(qi)(qi)可(ke)能會當場喪命(ming)！

低壓電器原理

低(di)(di)壓(ya)電(dian)(dian)(dian)器(qi)是(shi)一種(zhong)能根據(ju)外界的(de)(de)信號和要求，手動或自動地接通、斷開電(dian)(dian)(dian)路(lu)，以(yi)實現對電(dian)(dian)(dian)路(lu)或非電(dian)(dian)(dian)對象的(de)(de)切換、控制(zhi)、保護、檢測、變換和調節的(de)(de)元件(jian)(jian)或設(she)備。控制(zhi)電(dian)(dian)(dian)器(qi)按其工作電(dian)(dian)(dian)壓(ya)的(de)(de)高(gao)低(di)(di)，以(yi)交流1200V、直流1500V為界，可(ke)(ke)劃分為高(gao)壓(ya)控制(zhi)電(dian)(dian)(dian)器(qi)和低(di)(di)壓(ya)控制(zhi)電(dian)(dian)(dian)器(qi)兩大類。總的(de)(de)來說(shuo)，低(di)(di)壓(ya)電(dian)(dian)(dian)器(qi)可(ke)(ke)以(yi)分為配(pei)電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)和控制(zhi)電(dian)(dian)(dian)器(qi)兩大類，是(shi)成(cheng)套電(dian)(dian)(dian)氣設(she)備的(de)(de)基(ji)本(ben)組成(cheng)元件(jian)(jian)。在工業、農業、交通、國防以(yi)及(ji)人們用電(dian)(dian)(dian)部門中，大多數采(cai)用低(di)(di)壓(ya)供(gong)電(dian)(dian)(dian)，因(yin)此電(dian)(dian)(dian)器(qi)元件(jian)(jian)的(de)(de)質(zhi)量(liang)將直接影響到低(di)(di)壓(ya)供(gong)電(dian)(dian)(dian)系(xi)統(tong)的(de)(de)可(ke)(ke)靠性。
