變(bian)(bian)壓器(qi)(qi)繞組溫控器(qi)(qi)是采(cai)用(yong)附加溫升的(de)原理而設計的(de)，采(cai)用(yong)國(guo)際先(xian)進技(ji)術，將(jiang)變(bian)(bian)壓器(qi)(qi)繞組溫控器(qi)(qi)、BL型變(bian)(bian)流器(qi)(qi)等合為一體，可輸(shu)出多(duo)種(zhong)形式的(de)輸(shu)出信號供后臺測控系(xi)統及二次儀(yi)表(biao)使用(yong)。 該產品(pin)具有(you)體積小、功能全、安裝方(fang)便、操(cao)作簡單等特點(dian)。 變(bian)(bian)壓器(qi)(qi)繞組溫控器(qi)(qi)，主要由彈性元(yuan)件、傳(chuan)感導管(guan)、感溫部件，電(dian)熱元(yuan)件、溫度(du)變(bian)(bian)送器(qi)(qi)、變(bian)(bian)流器(qi)(qi)和數顯儀(yi)組成。

溫控器(qi)的工作原理如下

變壓(ya)(ya)(ya)(ya)器(qi)繞組(zu)溫(wen)(wen)控(kong)器(qi)的(de)(de)(de)(de)(de)(de)溫(wen)(wen)包插在(zai)變壓(ya)(ya)(ya)(ya)器(qi)油(you)箱頂層的(de)(de)(de)(de)(de)(de)油(you)孔內，當(dang)變壓(ya)(ya)(ya)(ya)器(qi)負(fu)荷(he)為零時，繞組(zu)溫(wen)(wen)控(kong)器(qi)的(de)(de)(de)(de)(de)(de)讀(du)數為變壓(ya)(ya)(ya)(ya)器(qi)油(you)的(de)(de)(de)(de)(de)(de)溫(wen)(wen)度。當(dang)變壓(ya)(ya)(ya)(ya)器(qi)帶上負(fu)荷(he)后(hou)，通過(guo)變壓(ya)(ya)(ya)(ya)器(qi)電(dian)(dian)流互(hu)感器(qi)取出的(de)(de)(de)(de)(de)(de)與(yu)負(fu)荷(he)成(cheng)正(zheng)比的(de)(de)(de)(de)(de)(de)電(dian)(dian)流。經變流器(qi)調(diao)整后(hou)流經嵌裝在(zai)玻(bo)紋管內的(de)(de)(de)(de)(de)(de)電(dian)(dian)熱(re)元(yuan)件。電(dian)(dian)熱(re)元(yuan)件產生的(de)(de)(de)(de)(de)(de)附加溫(wen)(wen)升的(de)(de)(de)(de)(de)(de)熱(re)量，推動(dong)儀表指(zhi)針繼續轉動(dong)。因(yin)此(ci)在(zai)變壓(ya)(ya)(ya)(ya)器(qi)帶上負(fu)荷(he)后(hou)，儀表指(zhi)示溫(wen)(wen)度是(shi)由(you)變壓(ya)(ya)(ya)(ya)器(qi)頂層油(you)篇和變壓(ya)(ya)(ya)(ya)器(qi)負(fu)荷(he)電(dian)(dian)流二者所決定，即變壓(ya)(ya)(ya)(ya)器(qi)頂層油(you)溫(wen)(wen)與(yu)線酬對油(you)的(de)(de)(de)(de)(de)(de)溫(wen)(wen)升之和，反映了被測變壓(ya)(ya)(ya)(ya)器(qi)線圈部(bu)位(wei)的(de)(de)(de)(de)(de)(de)溫(wen)(wen)度。
