低壓電器分類
低壓電器品牌產品有(you)很多,其結(jie)構、用途(tu)及(ji)所(suo)控制對象(xiang)的不同,可(ke)以有(you)不同的分(fen)(fen)類方式。按(an)用途(tu)和(he)(he)控制對象(xiang)不同,可(ke)將低壓電(dian)器分(fen)(fen)為(wei)配電(dian)電(dian)器和(he)(he)控制電(dian)器。按(an)操作方式不同,可(ke)將低壓電(dian)器分(fen)(fen)為(wei)自動電(dian)器和(he)(he)手(shou)動電(dian)器。按(an)工作原理可(ke)分(fen)(fen)為(wei)電(dian)磁式電(dian)器和(he)(he)非(fei)電(dian)量控制電(dian)器。
低壓電器的定義
低壓(ya)電器(qi)(qi)通常是指(zhi)在(zai)交流(liu)電壓(ya)1200V或直流(liu)電壓(ya)1500V以下工(gong)作的(de)電器(qi)(qi)。常見的(de)低壓(ya)器(qi)(qi)有開關、熔斷器(qi)(qi)、接觸(chu)器(qi)(qi)、漏電保護器(qi)(qi)和繼(ji)電器(qi)(qi)等。
低壓電器的作用有哪些
低壓電(dian)器能夠(gou)依據(ju)操作信號(hao)或外(wai)界現(xian)場信號(hao)的要(yao)求,自動或手動地改變電(dian)路(lu)的狀態、參數(shu),實現(xian)對電(dian)路(lu)或被控對象的控制、指示、測量、保護、調節。
低壓電器和高壓電器的主要區別
低(di)壓(ya)(ya)(ya)(ya)電(dian)(dian)器和高(gao)壓(ya)(ya)(ya)(ya)電(dian)(dian)器最大(da)的區別就(jiu)是(shi)工作電(dian)(dian)壓(ya)(ya)(ya)(ya)的不同,其次二者的安全性(xing)也因此不同,高(gao)壓(ya)(ya)(ya)(ya)電(dian)(dian)器有更(geng)多防護(hu)。一般來(lai)說誤(wu)觸(chu)低(di)壓(ya)(ya)(ya)(ya)電(dian)(dian)器有很(hen)大(da)希望救命,但是(shi)誤(wu)觸(chu)高(gao)壓(ya)(ya)(ya)(ya)電(dian)(dian)器可(ke)能會當場喪命!
低壓電器原理
低壓(ya)電(dian)(dian)(dian)器(qi)(qi)是一(yi)種能根據(ju)外(wai)界的信號和要求(qiu),手(shou)動(dong)或(huo)自動(dong)地接(jie)通(tong)、斷開電(dian)(dian)(dian)路,以實現(xian)對電(dian)(dian)(dian)路或(huo)非電(dian)(dian)(dian)對象的切(qie)換、控(kong)(kong)制(zhi)、保(bao)護、檢測、變換和調(diao)節(jie)的元件或(huo)設備。控(kong)(kong)制(zhi)電(dian)(dian)(dian)器(qi)(qi)按其工(gong)作電(dian)(dian)(dian)壓(ya)的高(gao)低,以交(jiao)流(liu)1200V、直(zhi)流(liu)1500V為(wei)界,可劃分為(wei)高(gao)壓(ya)控(kong)(kong)制(zhi)電(dian)(dian)(dian)器(qi)(qi)和低壓(ya)控(kong)(kong)制(zhi)電(dian)(dian)(dian)器(qi)(qi)兩大類(lei)(lei)。總(zong)的來說,低壓(ya)電(dian)(dian)(dian)器(qi)(qi)可以分為(wei)配電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)(qi)和控(kong)(kong)制(zhi)電(dian)(dian)(dian)器(qi)(qi)兩大類(lei)(lei),是成套電(dian)(dian)(dian)氣設備的基本組成元件。在工(gong)業(ye)、農業(ye)、交(jiao)通(tong)、國防以及人們用(yong)(yong)電(dian)(dian)(dian)部門中,大多(duo)數采用(yong)(yong)低壓(ya)供電(dian)(dian)(dian),因此(ci)電(dian)(dian)(dian)器(qi)(qi)元件的質(zhi)量將直(zhi)接(jie)影響到低壓(ya)供電(dian)(dian)(dian)系(xi)統的可靠(kao)性。
