低壓電器分類

低壓電器品牌產品有很多，其(qi)結構(gou)、用途(tu)及所控制對(dui)象的不同(tong)，可以有不同(tong)的分(fen)(fen)類方式。按(an)用途(tu)和(he)控制對(dui)象不同(tong)，可將(jiang)低壓(ya)(ya)電(dian)(dian)(dian)器(qi)(qi)(qi)分(fen)(fen)為配(pei)電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)(qi)(qi)和(he)控制電(dian)(dian)(dian)器(qi)(qi)(qi)。按(an)操(cao)作方式不同(tong)，可將(jiang)低壓(ya)(ya)電(dian)(dian)(dian)器(qi)(qi)(qi)分(fen)(fen)為自(zi)動(dong)電(dian)(dian)(dian)器(qi)(qi)(qi)和(he)手動(dong)電(dian)(dian)(dian)器(qi)(qi)(qi)。按(an)工作原(yuan)理可分(fen)(fen)為電(dian)(dian)(dian)磁式電(dian)(dian)(dian)器(qi)(qi)(qi)和(he)非電(dian)(dian)(dian)量控制電(dian)(dian)(dian)器(qi)(qi)(qi)。

低壓電器的定義

低壓(ya)(ya)電(dian)(dian)器(qi)(qi)通常是指在交流電(dian)(dian)壓(ya)(ya)1200V或直流電(dian)(dian)壓(ya)(ya)1500V以(yi)下(xia)工作的(de)電(dian)(dian)器(qi)(qi)。常見的(de)低壓(ya)(ya)器(qi)(qi)有開關、熔(rong)斷器(qi)(qi)、接觸(chu)器(qi)(qi)、漏(lou)電(dian)(dian)保護器(qi)(qi)和繼電(dian)(dian)器(qi)(qi)等(deng)。

低壓電器的作用有哪些

低(di)壓電(dian)器能(neng)夠依據(ju)操(cao)作信號或(huo)(huo)外(wai)界現(xian)(xian)場信號的(de)要求，自動或(huo)(huo)手(shou)動地改(gai)變電(dian)路(lu)的(de)狀態(tai)、參(can)數，實現(xian)(xian)對電(dian)路(lu)或(huo)(huo)被控(kong)對象的(de)控(kong)制、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(di)壓(ya)電(dian)(dian)(dian)器和(he)高(gao)壓(ya)電(dian)(dian)(dian)器最大(da)(da)的區別就是工作電(dian)(dian)(dian)壓(ya)的不(bu)同(tong)，其次(ci)二者的安全性也因此(ci)不(bu)同(tong)，高(gao)壓(ya)電(dian)(dian)(dian)器有更多防護。一(yi)般來說誤觸(chu)低(di)壓(ya)電(dian)(dian)(dian)器有很大(da)(da)希望救(jiu)命(ming)，但是誤觸(chu)高(gao)壓(ya)電(dian)(dian)(dian)器可(ke)能會當(dang)場喪命(ming)！

低壓電器原理

低(di)壓(ya)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)是一種(zhong)能根據外(wai)界的(de)(de)信號(hao)和(he)(he)要求，手動或自動地接通、斷開電(dian)(dian)(dian)(dian)(dian)路，以(yi)(yi)實現對(dui)電(dian)(dian)(dian)(dian)(dian)路或非(fei)電(dian)(dian)(dian)(dian)(dian)對(dui)象的(de)(de)切換、控(kong)(kong)制、保護、檢測、變(bian)換和(he)(he)調節的(de)(de)元件(jian)(jian)或設(she)備(bei)。控(kong)(kong)制電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)按其(qi)工作電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)高低(di)，以(yi)(yi)交(jiao)(jiao)流1200V、直流1500V為(wei)界，可(ke)劃分(fen)為(wei)高壓(ya)控(kong)(kong)制電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)和(he)(he)低(di)壓(ya)控(kong)(kong)制電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)兩大類(lei)。總的(de)(de)來說，低(di)壓(ya)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)可(ke)以(yi)(yi)分(fen)為(wei)配電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)和(he)(he)控(kong)(kong)制電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)兩大類(lei)，是成套電(dian)(dian)(dian)(dian)(dian)氣設(she)備(bei)的(de)(de)基本(ben)組成元件(jian)(jian)。在工業、農業、交(jiao)(jiao)通、國防以(yi)(yi)及人們用電(dian)(dian)(dian)(dian)(dian)部門中(zhong)，大多(duo)數采用低(di)壓(ya)供(gong)電(dian)(dian)(dian)(dian)(dian)，因此電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)元件(jian)(jian)的(de)(de)質量將直接影響到(dao)低(di)壓(ya)供(gong)電(dian)(dian)(dian)(dian)(dian)系統(tong)的(de)(de)可(ke)靠性(xing)。
