　　溫度對于變壓器運行的影響是比較大的，對于變壓器的溫度應該要適時進行測量，發現變壓器的溫度出現問題要立即停止工作進行檢修。變壓器的溫度隨著變壓器的運行也是不斷地升高的，對于變壓器的溫度升高也是有著一定的極限和標準的，并不是說無限制的進行升高。常見的對變壓器在極限溫度下是怎么樣進行工作的呢?以下是詳細地過程供大家進行參考：

　　變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)如(ru)長時(shi)間(jian)在(zai)(zai)極(ji)(ji)限(xian)(xian)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)下(xia)(xia)運(yun)行會(hui)產生(sheng)什么(me)危害。先先我們(men)(men)來了解(jie)一(yi)下(xia)(xia)什么(me)是極(ji)(ji)限(xian)(xian)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)，極(ji)(ji)限(xian)(xian)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)是指材料或(huo)者產品(pin)在(zai)(zai)出現失效之間(jian)能(neng)免達到(dao)的更高(gao)(gao)(gao)或(huo)更低溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)。又稱(cheng)“理論冷(leng)卻極(ji)(ji)限(xian)(xian)”。循環水(shui)在(zai)(zai)水(shui)氣接觸的冷(leng)卻過(guo)程中(zhong),當冷(leng)卻設備中(zhong)水(shui)的蒸發散熱(re)量與(yu)空(kong)氣向水(shui)的接觸傳熱(re)量相等時(shi),冷(leng)卻水(shui)所達到(dao)的平(ping)衡狀態極(ji)(ji)限(xian)(xian)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)。在(zai)(zai)這里我們(men)(men)所說的變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)長時(shi)間(jian)在(zai)(zai)極(ji)(ji)限(xian)(xian)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)下(xia)(xia)運(yun)行指是是油(you)(you)浸變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)一(yi)般變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)的主(zhu)要(yao)絕(jue)(jue)(jue)緣(yuan)(yuan)是A級絕(jue)(jue)(jue)緣(yuan)(yuan)，規定(ding)更高(gao)(gao)(gao)使用溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)為105度(du)(du)(du)(du)(du)，變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)在(zai)(zai)運(yun)行中(zhong)繞(rao)組(zu)(zu)的溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)要(yao)比(bi)上(shang)(shang)層油(you)(you)溫(wen)(wen)(wen)高(gao)(gao)(gao)10—15度(du)(du)(du)(du)(du)。如(ru)果運(yun)行中(zhong)的變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)上(shang)(shang)層油(you)(you)溫(wen)(wen)(wen)總在(zai)(zai)80-90度(du)(du)(du)(du)(du)左右，也就(jiu)是繞(rao)組(zu)(zu)經常在(zai)(zai)95-105度(du)(du)(du)(du)(du)左右，就(jiu)會(hui)因(yin)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)過(guo)高(gao)(gao)(gao)使絕(jue)(jue)(jue)緣(yuan)(yuan)老化(hua)嚴重，加(jia)快絕(jue)(jue)(jue)緣(yuan)(yuan)油(you)(you)的劣化(hua)，影響使用壽命。油(you)(you)浸變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)多為A級絕(jue)(jue)(jue)緣(yuan)(yuan)，其耐(nai)熱(re)更高(gao)(gao)(gao)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)允(yun)許105℃，變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)運(yun)行中(zhong)繞(rao)組(zu)(zu)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)要(yao)比(bi)上(shang)(shang)層油(you)(you)的平(ping)均溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)高(gao)(gao)(gao)出10-15℃，就(jiu)是當運(yun)行中(zhong)上(shang)(shang)層油(you)(you)溫(wen)(wen)(wen)達85-95℃時(shi)實際(ji)上(shang)(shang)繞(rao)組(zu)(zu)已(yi)達105℃左右.

　　以上(shang)是變(bian)(bian)壓器(qi)在極限地(di)(di)溫度和(he)狀態(tai)下進行(xing)(xing)工作的過(guo)程，對于變(bian)(bian)壓器(qi)要不斷(duan)(duan)地(di)(di)進行(xing)(xing)增強溫度地(di)(di)影響和(he)防范的性能，實現變(bian)(bian)壓器(qi)的溫度的檢測(ce)，讓變(bian)(bian)壓器(qi)的安全的效率發揮出來，實現變(bian)(bian)壓器(qi)的各(ge)種的功能的不斷(duan)(duan)地(di)(di)提升，實現變(bian)(bian)壓器(qi)良好(hao)地(di)(di)效果。
