一、調壓器是什么
調壓器顧名(ming)思義就是(shi)調(diao)節電壓(ya)的(de)(de)，又叫電壓(ya)調(diao)整器(qi)。一(yi)般(ban)(ban)用于科研、實驗、檢測、加熱(re)保(bao)溫、軟啟動等場合(he)，給負(fu)載提供不(bu)同的(de)(de)電壓(ya)，并且電壓(ya)可(ke)以在(zai)通電的(de)(de)情況(kuang)下(xia)線性調(diao)節。小型調(diao)壓(ya)器(qi)都是(shi)接觸(chu)式的(de)(de)，容(rong)量一(yi)般(ban)(ban)在(zai)30KVA以下(xia)，單相220V輸(shu)入，0-250V輸(shu)出(chu)；三(san)相380V輸(shu)入，0-420輸(shu)出(chu)。大型調(diao)壓(ya)器(qi)種類就比(bi)較多，且容(rong)量、規(gui)格、都可(ke)以按照要求(qiu)來(lai)設(she)計生(sheng)產。像(xiang)平時(shi)最常見的(de)(de)穩壓(ya)器(qi)就是(shi)調(diao)壓(ya)器(qi)的(de)(de)一(yi)種，也常稱(cheng)為自動調(diao)壓(ya)器(qi)。
二、調壓器有什么作用
調(diao)壓(ya)器(qi)最大的(de)(de)(de)作用(yong)(yong)(yong)是保(bao)持燃氣在使用(yong)(yong)(yong)時有穩定的(de)(de)(de)壓(ya)力，從(cong)而保(bao)證燃氣用(yong)(yong)(yong)具得(de)到穩定的(de)(de)(de)燃空比(bi)（燃氣與空氣的(de)(de)(de)配合(he)比(bi)例）；燃氣供應系統中使用(yong)(yong)(yong)調(diao)壓(ya)器(qi)將(jiang)氣體壓(ya)力降低，并穩定在一個能(neng)夠使氣體得(de)到安全、經濟(ji)和(he)高(gao)效利用(yong)(yong)(yong)的(de)(de)(de)適當(dang)水平上。
調壓器能(neng)給負(fu)載也可(ke)調電(dian)(dian)(dian)壓(ya)(ya)的調壓(ya)(ya)電(dian)(dian)(dian)源(yuan)(yuan)，不可(ke)調節的電(dian)(dian)(dian)網配電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)，還有(you)在一定(ding)范圍內平滑無級調節的負(fu)載電(dian)(dian)(dian)壓(ya)(ya)都是(shi)(shi)靠它來轉(zhuan)變(bian)的。能(neng)負(fu)載以穩(wen)定(ding)電(dian)(dian)(dian)壓(ya)(ya)的穩(wen)壓(ya)(ya)電(dian)(dian)(dian)源(yuan)(yuan)是(shi)(shi)自動(dong)(dong)調壓(ya)(ya)器，在電(dian)(dian)(dian)網電(dian)(dian)(dian)壓(ya)(ya)和負(fu)載電(dian)(dian)(dian)流不斷變(bian)動(dong)(dong)的情況下(xia)就是(shi)(shi)由(you)它來轉(zhuan)變(bian)不穩(wen)定(ding)的配電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)。特殊設(she)計的調壓(ya)(ya)器和自動(dong)(dong)控制器是(shi)(shi)自動(dong)(dong)調壓(ya)(ya)器的主要組成。
