一、調壓器是什么
調壓器顧(gu)名思(si)義就(jiu)是調節(jie)電(dian)(dian)壓(ya)(ya)的(de)，又叫電(dian)(dian)壓(ya)(ya)調整器(qi)(qi)。一般(ban)用于科(ke)研(yan)、實驗、檢測、加熱保溫(wen)、軟啟動等場合，給負載提供不同(tong)的(de)電(dian)(dian)壓(ya)(ya)，并且電(dian)(dian)壓(ya)(ya)可(ke)以在通電(dian)(dian)的(de)情況(kuang)下線性(xing)調節(jie)。小型調壓(ya)(ya)器(qi)(qi)都(dou)是接(jie)觸式的(de)，容(rong)量一般(ban)在30KVA以下，單相220V輸入，0-250V輸出；三相380V輸入，0-420輸出。大型調壓(ya)(ya)器(qi)(qi)種(zhong)類就(jiu)比較多(duo)，且容(rong)量、規格、都(dou)可(ke)以按照要(yao)求來設計生產。像平時最常見的(de)穩壓(ya)(ya)器(qi)(qi)就(jiu)是調壓(ya)(ya)器(qi)(qi)的(de)一種(zhong)，也常稱(cheng)為自動調壓(ya)(ya)器(qi)(qi)。
二、調壓器有什么作用
調壓(ya)(ya)器最大(da)的(de)作用是保持燃氣(qi)(qi)在使(shi)(shi)用時有穩定(ding)(ding)的(de)壓(ya)(ya)力(li)，從而(er)保證燃氣(qi)(qi)用具得到(dao)穩定(ding)(ding)的(de)燃空比（燃氣(qi)(qi)與(yu)空氣(qi)(qi)的(de)配合比例(li)）；燃氣(qi)(qi)供(gong)應系統中使(shi)(shi)用調壓(ya)(ya)器將氣(qi)(qi)體壓(ya)(ya)力(li)降低，并穩定(ding)(ding)在一個能夠(gou)使(shi)(shi)氣(qi)(qi)體得到(dao)安全、經(jing)濟(ji)和高效利用的(de)適當水平上。
調壓器能(neng)給負載(zai)也可調(diao)(diao)電(dian)(dian)(dian)壓(ya)(ya)的(de)(de)(de)調(diao)(diao)壓(ya)(ya)電(dian)(dian)(dian)源(yuan)，不可調(diao)(diao)節的(de)(de)(de)電(dian)(dian)(dian)網配(pei)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)，還有在(zai)一定(ding)范圍(wei)內平滑無級調(diao)(diao)節的(de)(de)(de)負載(zai)電(dian)(dian)(dian)壓(ya)(ya)都是(shi)靠它(ta)來轉變(bian)的(de)(de)(de)。能(neng)負載(zai)以穩定(ding)電(dian)(dian)(dian)壓(ya)(ya)的(de)(de)(de)穩壓(ya)(ya)電(dian)(dian)(dian)源(yuan)是(shi)自(zi)動(dong)調(diao)(diao)壓(ya)(ya)器(qi)(qi)，在(zai)電(dian)(dian)(dian)網電(dian)(dian)(dian)壓(ya)(ya)和(he)負載(zai)電(dian)(dian)(dian)流(liu)不斷變(bian)動(dong)的(de)(de)(de)情況(kuang)下(xia)就是(shi)由它(ta)來轉變(bian)不穩定(ding)的(de)(de)(de)配(pei)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)。特(te)殊設(she)計的(de)(de)(de)調(diao)(diao)壓(ya)(ya)器(qi)(qi)和(he)自(zi)動(dong)控制(zhi)器(qi)(qi)是(shi)自(zi)動(dong)調(diao)(diao)壓(ya)(ya)器(qi)(qi)的(de)(de)(de)主要組成。
