低壓電器分類
低壓電器品牌產品有很多(duo),其結(jie)構、用(yong)途(tu)及(ji)所控制(zhi)(zhi)對象的不同(tong),可(ke)以有不同(tong)的分類方式。按用(yong)途(tu)和(he)控制(zhi)(zhi)對象不同(tong),可(ke)將(jiang)低(di)壓電器(qi)(qi)分為配電電器(qi)(qi)和(he)控制(zhi)(zhi)電器(qi)(qi)。按操作(zuo)(zuo)方式不同(tong),可(ke)將(jiang)低(di)壓電器(qi)(qi)分為自動電器(qi)(qi)和(he)手(shou)動電器(qi)(qi)。按工作(zuo)(zuo)原理可(ke)分為電磁式電器(qi)(qi)和(he)非電量控制(zhi)(zhi)電器(qi)(qi)。
低壓電器的定義
低壓電器(qi)(qi)通常是指在交(jiao)流(liu)電壓1200V或直(zhi)流(liu)電壓1500V以下工(gong)作的(de)電器(qi)(qi)。常見的(de)低壓器(qi)(qi)有開關、熔斷器(qi)(qi)、接觸器(qi)(qi)、漏(lou)電保護器(qi)(qi)和繼(ji)電器(qi)(qi)等。
低壓電器的作用有哪些
低壓電器(qi)能夠(gou)依據(ju)操作信(xin)號(hao)或(huo)外界現(xian)場信(xin)號(hao)的要求(qiu),自(zi)動或(huo)手動地改變電路(lu)的狀態、參數,實(shi)現(xian)對電路(lu)或(huo)被(bei)控對象的控制、指(zhi)示、測量、保護、調節。
低壓電器和高壓電器的主要區別
低壓(ya)電(dian)(dian)(dian)器和高(gao)壓(ya)電(dian)(dian)(dian)器最大(da)的區(qu)別就是(shi)工作電(dian)(dian)(dian)壓(ya)的不同(tong),其次二(er)者的安(an)全性(xing)也(ye)因此不同(tong),高(gao)壓(ya)電(dian)(dian)(dian)器有更多防護。一般來說誤觸低壓(ya)電(dian)(dian)(dian)器有很(hen)大(da)希望(wang)救命,但(dan)是(shi)誤觸高(gao)壓(ya)電(dian)(dian)(dian)器可能會當場喪(sang)命!
低壓電器原理
低(di)(di)壓(ya)(ya)電(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)一種能根據外界的(de)信號(hao)和要求(qiu),手(shou)動或自動地接(jie)通、斷開電(dian)(dian)(dian)(dian)路(lu),以實(shi)現對電(dian)(dian)(dian)(dian)路(lu)或非電(dian)(dian)(dian)(dian)對象的(de)切換、控(kong)制(zhi)(zhi)、保護、檢測、變(bian)換和調節的(de)元(yuan)件或設備(bei)(bei)。控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)器(qi)(qi)按其工作(zuo)電(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)高低(di)(di),以交(jiao)流(liu)1200V、直(zhi)流(liu)1500V為(wei)界,可(ke)劃(hua)分為(wei)高壓(ya)(ya)控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)器(qi)(qi)和低(di)(di)壓(ya)(ya)控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)器(qi)(qi)兩(liang)(liang)大(da)(da)類。總的(de)來說,低(di)(di)壓(ya)(ya)電(dian)(dian)(dian)(dian)器(qi)(qi)可(ke)以分為(wei)配電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)器(qi)(qi)和控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)器(qi)(qi)兩(liang)(liang)大(da)(da)類,是(shi)成(cheng)套電(dian)(dian)(dian)(dian)氣設備(bei)(bei)的(de)基(ji)本組(zu)成(cheng)元(yuan)件。在(zai)工業、農業、交(jiao)通、國防以及人們用電(dian)(dian)(dian)(dian)部門(men)中,大(da)(da)多(duo)數采用低(di)(di)壓(ya)(ya)供電(dian)(dian)(dian)(dian),因此電(dian)(dian)(dian)(dian)器(qi)(qi)元(yuan)件的(de)質量將直(zhi)接(jie)影響到(dao)低(di)(di)壓(ya)(ya)供電(dian)(dian)(dian)(dian)系(xi)統的(de)可(ke)靠(kao)性。
