變(bian)(bian)壓器繞(rao)組溫控(kong)器是采(cai)(cai)用(yong)(yong)附加溫升的原理(li)而設計的，采(cai)(cai)用(yong)(yong)國(guo)際先進技術，將變(bian)(bian)壓器繞(rao)組溫控(kong)器、BL型變(bian)(bian)流器等(deng)合為一(yi)體，可輸(shu)出多種形式(shi)的輸(shu)出信號供后(hou)臺(tai)測控(kong)系統及(ji)二次儀表使用(yong)(yong)。 該產品(pin)具(ju)有體積小、功能全、安裝(zhuang)方便、操作簡單等(deng)特點。 變(bian)(bian)壓器繞(rao)組溫控(kong)器，主要由彈性元件、傳感導(dao)管(guan)、感溫部件，電熱元件、溫度(du)變(bian)(bian)送器、變(bian)(bian)流器和數顯儀組成。

溫控器的工作原理如下

變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)繞組(zu)溫(wen)(wen)控器(qi)(qi)的(de)(de)溫(wen)(wen)包(bao)插在(zai)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)油(you)箱(xiang)頂層的(de)(de)油(you)孔內，當(dang)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)負荷(he)為(wei)零時，繞組(zu)溫(wen)(wen)控器(qi)(qi)的(de)(de)讀數為(wei)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)油(you)的(de)(de)溫(wen)(wen)度(du)。當(dang)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)帶上負荷(he)后(hou)，通過(guo)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)電(dian)流(liu)互感器(qi)(qi)取出的(de)(de)與(yu)負荷(he)成正比的(de)(de)電(dian)流(liu)。經變(bian)(bian)(bian)流(liu)器(qi)(qi)調(diao)整后(hou)流(liu)經嵌裝在(zai)玻(bo)紋管內的(de)(de)電(dian)熱元(yuan)件(jian)。電(dian)熱元(yuan)件(jian)產生(sheng)的(de)(de)附加溫(wen)(wen)升(sheng)的(de)(de)熱量，推動(dong)儀表(biao)指針(zhen)繼續轉動(dong)。因此(ci)在(zai)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)帶上負荷(he)后(hou)，儀表(biao)指示溫(wen)(wen)度(du)是由變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)頂層油(you)篇和變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)負荷(he)電(dian)流(liu)二(er)者所決(jue)定，即變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)頂層油(you)溫(wen)(wen)與(yu)線酬對油(you)的(de)(de)溫(wen)(wen)升(sheng)之(zhi)和，反映了被(bei)測(ce)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)線圈部(bu)位的(de)(de)溫(wen)(wen)度(du)。
