箱式變壓器廠家分析大型變壓器怎么進行測溫

一(yi) 、變(bian)壓器(qi)油溫(wen)(wen)監(jian)(jian)測變(bian)壓器(qi)油溫(wen)(wen)應(ying)選用鉑熱(re)電阻(Pt100)三線(xian)制丈量(liang)方式(shi)丈量(liang)，變(bian)壓器(qi)油溫(wen)(wen)維(wei)護及監(jian)(jian)測由鉑熱(re)電阻和數字式(shi)溫(wen)(wen)度顯(xian)(xian)現調理(li)儀(yi)聯合構(gou)成。數字式(shi)溫(wen)(wen)度顯(xian)(xian)現調理(li)儀(yi)應(ying)輸(shu)(shu)出一(yi)路(lu)4~20mA模擬 量(liang)至全廠(chang)計算機監(jian)(jian)控(kong)體(ti)系(xi)(xi);別(bie)的，應(ying)分(fen)別(bie)輸(shu)(shu)出一(yi)對溫(wen)(wen)度過高信號接點(dian)和一(yi)對油溫(wen)(wen)增加(jia)信號接點(dian)至變(bian)壓器(qi)維(wei)護體(ti)系(xi)(xi)。數字式(shi)溫(wen)(wen)度顯(xian)(xian)現調理(li)儀(yi)的安裝方位應(ying)便于調查。

二 、變(bian)(bian)壓器(qi)線(xian)(xian)圈溫度(du)(du)監測變(bian)(bian)壓器(qi)線(xian)(xian)圈溫度(du)(du)維護儀應(ying)輸出一路4~20mA模擬量(liang)至(zhi)全(quan)廠計算機監控(kong)體(ti)系(xi);別(bie)的(de)，應(ying)分別(bie)輸出一對(dui)線(xian)(xian)圈溫度(du)(du)過高信號(hao)接點和一對(dui)線(xian)(xian)圈溫度(du)(du)增加信號(hao)接點至(zhi)變(bian)(bian)壓器(qi)維護體(ti)系(xi)。變(bian)(bian) 壓器(qi)線(xian)(xian)圈溫度(du)(du)丈量(liang)設備(包含信號(hao)源、丈量(liang)及(ji)變(bian)(bian)換設備等)均(jun)應(ying)由賣方成套(tao)供貨，如(ru)選用(yong)電流丈量(liang)法，請(qing)求(qiu)高壓套(tao)管內所配(pei)電流互感器(qi)精度(du)(du)為0.2級(ji)。
