箱式變電站廠家解析(xi)大型變壓器(qi)怎么進行(xing)測溫(wen)

一(yi)(yi) 、變(bian)壓(ya)器油(you)(you)溫(wen)監測(ce)變(bian)壓(ya)器油(you)(you)溫(wen)應(ying)(ying)選(xuan)用鉑熱電阻(zu)(Pt100)三線制丈量方式(shi)丈量，變(bian)壓(ya)器油(you)(you)溫(wen)維(wei)護及(ji)監測(ce)由鉑熱電阻(zu)和數(shu)(shu)字式(shi)溫(wen)度(du)(du)(du)顯現調理(li)儀聯(lian)合構成。數(shu)(shu)字式(shi)溫(wen)度(du)(du)(du)顯現調理(li)儀應(ying)(ying)輸(shu)出一(yi)(yi)路4~20mA模擬 量至(zhi)全(quan)廠計(ji)算機監控體系(xi);別的(de)，應(ying)(ying)分別輸(shu)出一(yi)(yi)對溫(wen)度(du)(du)(du)過(guo)高信號接(jie)點和一(yi)(yi)對油(you)(you)溫(wen)增加(jia)信號接(jie)點至(zhi)變(bian)壓(ya)器維(wei)護體系(xi)。數(shu)(shu)字式(shi)溫(wen)度(du)(du)(du)顯現調理(li)儀的(de)安(an)裝方位應(ying)(ying)便于(yu)調查。

二 、變(bian)壓(ya)器(qi)線(xian)(xian)(xian)圈溫度(du)(du)監測變(bian)壓(ya)器(qi)線(xian)(xian)(xian)圈溫度(du)(du)維護儀應輸(shu)出一路4~20mA模擬量至全廠計算機監控體(ti)系(xi);別(bie)的，應分別(bie)輸(shu)出一對(dui)線(xian)(xian)(xian)圈溫度(du)(du)過高(gao)(gao)信號(hao)接(jie)(jie)點(dian)和一對(dui)線(xian)(xian)(xian)圈溫度(du)(du)增加信號(hao)接(jie)(jie)點(dian)至變(bian)壓(ya)器(qi)維護體(ti)系(xi)。變(bian) 壓(ya)器(qi)線(xian)(xian)(xian)圈溫度(du)(du)丈(zhang)(zhang)量設(she)備(包含信號(hao)源、丈(zhang)(zhang)量及變(bian)換設(she)備等)均應由賣方成套(tao)供(gong)貨(huo)，如(ru)選(xuan)用電流(liu)(liu)丈(zhang)(zhang)量法(fa)，請求高(gao)(gao)壓(ya)套(tao)管內所配電流(liu)(liu)互感器(qi)精度(du)(du)為0.2級(ji)。
