蘭州變壓器油(you)(you)(you)(you)(you)量看儲(chu)(chu)(chu)罐柜(ju)，別稱油(you)(you)(you)(you)(you)枕。儲(chu)(chu)(chu)罐柜(ju)，別稱油(you)(you)(you)(you)(you)枕，為一圓桶行容器(qi)(qi)(qi)，橫著于機(ji)油(you)(you)(you)(you)(you)箱(xiang)上(shang)面(mian)，用管(guan)路與油(you)(you)(you)(you)(you)浸(jin)(jin)式(shi)變(bian)壓器(qi)(qi)(qi)的(de)機(ji)油(you)(you)(you)(you)(you)箱(xiang)連接。當油(you)(you)(you)(you)(you)浸(jin)(jin)式(shi)變(bian)壓器(qi)(qi)(qi)油(you)(you)(you)(you)(you)熱變(bian)形(xing)時(shi)，油(you)(you)(you)(you)(you)由(you)油(you)(you)(you)(you)(you)槽流(liu)入(ru)儲(chu)(chu)(chu)罐柜(ju)，當油(you)(you)(you)(you)(you)浸(jin)(jin)式(shi)變(bian)壓器(qi)(qi)(qi)油(you)(you)(you)(you)(you)熱縮時(shi)，油(you)(you)(you)(you)(you)由(you)儲(chu)(chu)(chu)罐柜(ju)流(liu)入(ru)機(ji)油(you)(you)(you)(you)(you)箱(xiang)。45KV及左(zuo)右額(e)定電壓或是容積非(fei)常大的(de)12KV油(you)(you)(you)(you)(you)變(bian)油(you)(you)(you)(you)(you)浸(jin)(jin)式(shi)變(bian)壓器(qi)(qi)(qi)都拼裝儲(chu)(chu)(chu)罐柜(ju)，儲(chu)(chu)(chu)油(you)(you)(you)(you)(you)柜(ju)的(de)剩余油(you)(you)(you)(you)(you)標志大約有(you)(you)那(nei)般幾種方法，連通(tong)管(guan)、羅盤油(you)(you)(you)(you)(you)量計、波紋軟管(guan)。《三相電力油(you)(you)(you)(you)(you)浸(jin)(jin)變(bian)壓器(qi)(qi)(qi)性能參數及規(gui)定》第4.1條“油(you)(you)(you)(you)(you)保護設(she)備(bei)”明確規(gui)定，配有(you)(you)儲(chu)(chu)(chu)罐柜(ju)的(de)油(you)(you)(you)(you)(you)變(bian)變(bian)壓器(qi)(qi)(qi)應有(you)(you)利(li)于內部(bu)構(gou)(gou)造(zao)清(qing)洗(xi)的(de)油(you)(you)(you)(you)(you)罐柜(ju)結(jie)構(gou)(gou)。

儲罐的容量應保證在(zai)自然環境(jing)平均溫度(du)為50°℃時油(you)不(bu)外流，在(zai)-40°℃無財產適用時油(you)位計應說明油(you)。

在油(you)浸式變(bian)壓器(qi)運(yun)行中，一般規定85℃為(wei)高(gao)(gao)層(ceng)溫(wen)度(du)界限(xian)，在東營市地區，當高(gao)(gao)層(ceng)溫(wen)度(du)做到80℃左右時，會傳出"XX主變(bian)本身(shen)氣溫(wen)高(gao)(gao)警報"。

油(you)浸式變(bian)(bian)壓器(qi)(qi)(qi)(qi)工作上溫(wen)度(du)，包含變(bian)(bian)壓器(qi)(qi)(qi)(qi)油(you)溫(wen)和變(bian)(bian)壓器(qi)(qi)(qi)(qi)繞(rao)阻溫(wen)度(du)。一(yi)(yi)般(ban)(ban)(ban)在外殼頂部安裝有一(yi)(yi)溫(wen)度(du)精(jing)確(que)(que)測量(liang)槽，插(cha)到變(bian)(bian)壓器(qi)(qi)(qi)(qi)油(you)內，根據這(zhe)其中(zhong)設(she)定值測量(liang)元器(qi)(qi)(qi)(qi)件，精(jing)確(que)(que)測量(liang)變(bian)(bian)壓器(qi)(qi)(qi)(qi)溫(wen)度(du)。由于精(jing)確(que)(que)測定的目標是對變(bian)(bian)壓器(qi)(qi)(qi)(qi)高層建(jian)筑的油(you)，因此大(da)家一(yi)(yi)般(ban)(ban)(ban)稱作變(bian)(bian)壓器(qi)(qi)(qi)(qi)高層建(jian)筑溫(wen)度(du)。由于變(bian)(bian)壓器(qi)(qi)(qi)(qi)在繞(rao)阻依據負(fu)荷的時(shi)(shi)候會導致發熱，故在運行中(zhong)變(bian)(bian)壓器(qi)(qi)(qi)(qi)運行中(zhong)變(bian)(bian)壓器(qi)(qi)(qi)(qi)的磁鐵線圈溫(wen)度(du)一(yi)(yi)定高于變(bian)(bian)壓器(qi)(qi)(qi)(qi)油(you)的溫(wen)度(du)。但在其中(zhong)對變(bian)(bian)壓器(qi)(qi)(qi)(qi)絕緣老化損(sun)害大(da)的，就是變(bian)(bian)壓器(qi)(qi)(qi)(qi)內部實(shi)時(shi)(shi)熱點(dian)溫(wen)度(du)，一(yi)(yi)般(ban)(ban)(ban)稱之(zhi)為實(shi)時(shi)(shi)熱點(dian)溫(wen)度(du)。

一般蘭州變壓器實時熱(re)點(dian)要在變壓器(qi)(qi)繞阻靠(kao)近頂端的(de)(de)一(yi)些(xie)位(wei)置。由(you)于無法(fa)精(jing)(jing)準定位(wei)，精(jing)(jing)準定位(wei)，所以(yi)我們(men)一(yi)般用(yong)變壓器(qi)(qi)繞阻溫(wen)(wen)度(du)(du)取代變壓器(qi)(qi)實時熱(re)點(dian)溫(wen)(wen)度(du)(du)，作為檢驗變壓器(qi)(qi)內部實時熱(re)點(dian)濕(shi)度(du)(du)的(de)(de)方法(fa)。因此油變變壓器(qi)(qi)一(yi)般都是(shi)會(hui)配置變壓器(qi)(qi)的(de)(de)高層建筑溫(wen)(wen)度(du)(du)儀和變壓器(qi)(qi)的(de)(de)繞阻溫(wen)(wen)度(du)(du)表。
