低壓電器分類

低壓電器品牌產品有很多，其結(jie)構(gou)、用途(tu)及所控(kong)(kong)制對象的不(bu)同(tong)，可(ke)以有不(bu)同(tong)的分(fen)類方式(shi)。按(an)用途(tu)和(he)控(kong)(kong)制對象不(bu)同(tong)，可(ke)將(jiang)低壓電(dian)器(qi)(qi)(qi)分(fen)為配電(dian)電(dian)器(qi)(qi)(qi)和(he)控(kong)(kong)制電(dian)器(qi)(qi)(qi)。按(an)操作方式(shi)不(bu)同(tong)，可(ke)將(jiang)低壓電(dian)器(qi)(qi)(qi)分(fen)為自(zi)動電(dian)器(qi)(qi)(qi)和(he)手動電(dian)器(qi)(qi)(qi)。按(an)工作原(yuan)理(li)可(ke)分(fen)為電(dian)磁式(shi)電(dian)器(qi)(qi)(qi)和(he)非電(dian)量控(kong)(kong)制電(dian)器(qi)(qi)(qi)。

低壓電器的定義

低壓(ya)電器通常(chang)是指在交流(liu)電壓(ya)1200V或直(zhi)流(liu)電壓(ya)1500V以(yi)下工作的電器。常(chang)見的低壓(ya)器有開關(guan)、熔斷器、接觸器、漏(lou)電保護器和繼電器等。

低壓電器的作用有哪些

低壓電器能夠依據操作信號或外界現(xian)場信號的要求，自動(dong)或手(shou)動(dong)地改變電路的狀態、參(can)數(shu)，實(shi)現(xian)對電路或被控對象的控制、指(zhi)示、測量、保(bao)護(hu)、調節。

低壓電器和高壓電器的主要區別

低(di)壓(ya)電器(qi)和高(gao)壓(ya)電器(qi)最大(da)的(de)區別就是(shi)工(gong)作電壓(ya)的(de)不同，其(qi)次二者的(de)安全性(xing)也因此不同，高(gao)壓(ya)電器(qi)有(you)更多防(fang)護。一般來說誤觸低(di)壓(ya)電器(qi)有(you)很(hen)大(da)希望救命(ming)，但是(shi)誤觸高(gao)壓(ya)電器(qi)可能會當場喪命(ming)！

低壓電器原理

低壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)是一種(zhong)能根據外界的(de)(de)信號和要求，手(shou)動或自動地接通、斷開(kai)電(dian)(dian)(dian)(dian)路，以實(shi)現對電(dian)(dian)(dian)(dian)路或非電(dian)(dian)(dian)(dian)對象的(de)(de)切(qie)換(huan)、控制、保護、檢(jian)測、變換(huan)和調節的(de)(de)元(yuan)件(jian)或設(she)備。控制電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)按其工(gong)作電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)高(gao)低，以交流1200V、直流1500V為(wei)界，可劃分為(wei)高(gao)壓(ya)(ya)(ya)控制電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)和低壓(ya)(ya)(ya)控制電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)兩(liang)(liang)大類(lei)。總(zong)的(de)(de)來說，低壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)可以分為(wei)配電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)和控制電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)兩(liang)(liang)大類(lei)，是成套電(dian)(dian)(dian)(dian)氣(qi)設(she)備的(de)(de)基本(ben)組成元(yuan)件(jian)。在工(gong)業、農業、交通、國防以及(ji)人們(men)用(yong)電(dian)(dian)(dian)(dian)部門中，大多數(shu)采(cai)用(yong)低壓(ya)(ya)(ya)供電(dian)(dian)(dian)(dian)，因(yin)此電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)元(yuan)件(jian)的(de)(de)質量將(jiang)直接影響到低壓(ya)(ya)(ya)供電(dian)(dian)(dian)(dian)系統的(de)(de)可靠性。
