晶閘(zha)管調壓器(qi)又稱(cheng)“晶閘(zha)管電(dian)力調整(zheng)器(qi)”“可控硅電(dian)力調整(zheng)器(qi)”或簡(jian)稱(cheng)“電(dian)力調整(zheng)器(qi)”。“晶閘(zha)管”又稱(cheng)“可控硅”（SCR）是(shi)一種四層(ceng)三端半導體(ti)器(qi)件，把它接在(zai)電(dian)源和負載中間，配上相(xiang) 應的觸發控制電(dian)路板(ban)，就可以(yi)調整(zheng)加到負載上的電(dian)壓、電(dian)流和功(gong)率。
調(diao)(diao)壓器(qi)分為：自耦調(diao)(diao)壓器(qi),隔(ge)離調(diao)(diao)壓器(qi)，油(you)浸式(shi)感(gan)應(ying)調(diao)(diao)壓器(qi)，柱式(shi)電動(dong)調(diao)(diao)壓器(qi)和晶閘(zha)管調(diao)(diao)壓器(qi)五種。
調壓(ya)器的工(gong)作方式分(fen)手動調壓(ya)和(he)電動調壓(ya).

晶(jing)閘(zha)管(guan)調(diao)(diao)壓器又(you)稱(cheng)“晶(jing)閘(zha)管(guan)電力(li)調(diao)(diao)整器”“可控硅電力(li)調(diao)(diao)整器”或簡稱(cheng)“電力(li)調(diao)(diao)整器” 。“晶(jing)閘(zha)管(guan)”
又稱“可控(kong)硅”（SCR）是一種四層(ceng)三端半(ban)導體器件，把它接在電(dian)(dian)源和負載中間，配上(shang)相(xiang)應(ying)的觸發控(kong)制(zhi)電(dian)(dian)路板，就可以調整加(jia)到負載上(shang)的電(dian)(dian)壓(ya)、電(dian)(dian)流(liu)和功率(lv)。
“晶(jing)閘(zha)管調整器”主(zhu)要用于(yu)各(ge)種電(dian)(dian)加熱裝(zhuang)置(zhi)（如電(dian)(dian)熱工(gong)業窯爐、電(dian)(dian)熱干燥機、電(dian)(dian)熱油(you)爐、各(ge)種反(fan)應罐、反(fan)應釜的電(dian)(dian)加熱裝(zhuang)置(zhi)）的加熱功(gong)率調整，既可以“手動(dong)”調整，又(you)可以和電(dian)(dian)動(dong)調節儀表、智能
調節儀(yi)表、PLC以及計算機(ji)控(kong)制(zhi)系統配合(he)，實(shi)現對加熱溫度(du)的(de)恒值或程序(xu)控(kong)制(zhi)。
