低壓電器分類

低壓電器品牌產品有很多(duo)，其結構(gou)、用(yong)途及(ji)所(suo)控(kong)制(zhi)對象的不(bu)同，可以(yi)有不(bu)同的分類方(fang)式(shi)。按用(yong)途和控(kong)制(zhi)對象不(bu)同，可將低壓電(dian)(dian)(dian)(dian)器(qi)(qi)分為配電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)器(qi)(qi)和控(kong)制(zhi)電(dian)(dian)(dian)(dian)器(qi)(qi)。按操作方(fang)式(shi)不(bu)同，可將低壓電(dian)(dian)(dian)(dian)器(qi)(qi)分為自動電(dian)(dian)(dian)(dian)器(qi)(qi)和手動電(dian)(dian)(dian)(dian)器(qi)(qi)。按工作原理可分為電(dian)(dian)(dian)(dian)磁式(shi)電(dian)(dian)(dian)(dian)器(qi)(qi)和非電(dian)(dian)(dian)(dian)量控(kong)制(zhi)電(dian)(dian)(dian)(dian)器(qi)(qi)。

低壓電器的定義

低(di)壓電(dian)(dian)器通常是指在交流(liu)電(dian)(dian)壓1200V或直流(liu)電(dian)(dian)壓1500V以下(xia)工作的電(dian)(dian)器。常見的低(di)壓器有(you)開關、熔斷器、接觸器、漏電(dian)(dian)保護器和繼電(dian)(dian)器等。

低壓電器的作用有哪些

低壓電器能夠依(yi)據操作信號(hao)或(huo)外界現場信號(hao)的(de)要求，自動或(huo)手動地改變(bian)電路(lu)(lu)的(de)狀態、參數，實現對電路(lu)(lu)或(huo)被(bei)控對象的(de)控制(zhi)、指(zhi)示、測量、保(bao)護、調(diao)節。

低壓電器和高壓電器的主要區別

低壓(ya)電(dian)器(qi)(qi)和高(gao)壓(ya)電(dian)器(qi)(qi)最大(da)的(de)(de)區別就是(shi)工(gong)作電(dian)壓(ya)的(de)(de)不(bu)同，其(qi)次二者(zhe)的(de)(de)安全性也(ye)因此不(bu)同，高(gao)壓(ya)電(dian)器(qi)(qi)有更多防護。一般來說誤觸低壓(ya)電(dian)器(qi)(qi)有很大(da)希望(wang)救命，但是(shi)誤觸高(gao)壓(ya)電(dian)器(qi)(qi)可能會(hui)當場喪命！

低壓電器原理

低壓(ya)電(dian)(dian)(dian)(dian)(dian)器(qi)是一種能(neng)根據外界的信號和要求，手動或自動地接通、斷(duan)開電(dian)(dian)(dian)(dian)(dian)路，以(yi)實(shi)現對電(dian)(dian)(dian)(dian)(dian)路或非電(dian)(dian)(dian)(dian)(dian)對象的切換、控制、保護、檢測(ce)、變換和調節的元件或設(she)備。控制電(dian)(dian)(dian)(dian)(dian)器(qi)按其工作電(dian)(dian)(dian)(dian)(dian)壓(ya)的高低，以(yi)交流1200V、直流1500V為(wei)界，可(ke)(ke)劃(hua)分為(wei)高壓(ya)控制電(dian)(dian)(dian)(dian)(dian)器(qi)和低壓(ya)控制電(dian)(dian)(dian)(dian)(dian)器(qi)兩大類。總的來說，低壓(ya)電(dian)(dian)(dian)(dian)(dian)器(qi)可(ke)(ke)以(yi)分為(wei)配電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)器(qi)和控制電(dian)(dian)(dian)(dian)(dian)器(qi)兩大類，是成(cheng)套(tao)電(dian)(dian)(dian)(dian)(dian)氣設(she)備的基(ji)本組成(cheng)元件。在工業(ye)、農業(ye)、交通、國防以(yi)及人們用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)部門中，大多(duo)數采(cai)用(yong)(yong)低壓(ya)供電(dian)(dian)(dian)(dian)(dian)，因此電(dian)(dian)(dian)(dian)(dian)器(qi)元件的質(zhi)量(liang)將直接影響(xiang)到低壓(ya)供電(dian)(dian)(dian)(dian)(dian)系統的可(ke)(ke)靠性。
