近日，由(you)中(zhong)國西(xi)電設計制(zhi)造的蒙(meng)西(xi)-天(tian)津南特高壓(ya)交流工程首(shou)臺1000kV 1000MVA電力變(bian)壓(ya)器順利通過試驗，各項性能指(zhi)標達到(dao)或(huo)優于國家標準和技術協議要(yao)求，標志著該工程首(shou)臺雙百萬變(bian)壓(ya)器在中(zhong)國西(xi)電研制(zhi)成功。

蒙西-天津南1000千伏特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)交流(liu)(liu)輸變(bian)電工(gong)(gong)程(cheng)(cheng)是國(guo)家(jia)電網華北(bei)特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)交直流(liu)(liu)主網架的(de)重要組成部(bu)分(fen)。2015年，中(zhong)(zhong)(zhong)國(guo)西電成功(gong)中(zhong)(zhong)(zhong)標蒙西-天津南特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)交流(liu)(liu)工(gong)(gong)程(cheng)(cheng)蒙西變(bian)電站7臺雙百(bai)萬變(bian)壓(ya)(ya)(ya)(ya)(ya)器(qi)和晉北(bei)變(bian)電站11臺特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)電抗(kang)器(qi)，是該(gai)批次特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)招標項(xiang)目(mu)中(zhong)(zhong)(zhong)中(zhong)(zhong)(zhong)標份額(e)最大的(de)變(bian)壓(ya)(ya)(ya)(ya)(ya)器(qi)廠家(jia)。該(gai)工(gong)(gong)程(cheng)(cheng)是中(zhong)(zhong)(zhong)國(guo)西電繼晉東南-南陽-荊門特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)示范(fan)工(gong)(gong)程(cheng)(cheng)、皖電東送特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)交流(liu)(liu)示范(fan)工(gong)(gong)程(cheng)(cheng)、浙北(bei)-福(fu)州特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)工(gong)(gong)程(cheng)(cheng)、淮(huai)南-上海特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)工(gong)(gong)程(cheng)(cheng)、錫盟-山東特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)工(gong)(gong)程(cheng)(cheng)之后，成功(gong)中(zhong)(zhong)(zhong)標的(de)又一(yi)特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)重點工(gong)(gong)程(cheng)(cheng)。

“蒙(meng)西-天津(jin)南1000kV特高壓(ya)交(jiao)(jiao)流工程”與先期建設的(de)特高壓(ya)交(jiao)(jiao)流工程相(xiang)比較，蒙(meng)西1000kV變電站處于大風(feng)沙(sha)地區，揚沙(sha)現象(xiang)較多，且(qie)有出現沙(sha)塵暴(bao)的(de)可能,同時(shi)現場最低環境溫度(du)達(da)-30.9℃，運行條件(jian)惡劣，對特高壓(ya)自耦(ou)變壓(ya)器(qi)的(de)安全(quan)可靠運行是極(ji)大的(de)考驗，因此防風(feng)沙(sha)及低溫啟動的(de)研究是本(ben)次設計的(de)關(guan)鍵。

設(she)計人(ren)員(yuan)在沿(yan)用(yong)前期特(te)高(gao)壓(ya)(ya)(ya)產品成(cheng)(cheng)熟結(jie)構(gou)，進一(yi)步推動國(guo)產化的同時，進行科研(yan)(yan)攻關、自主創(chuang)新。完成(cheng)(cheng)了高(gao)寒及(ji)(ji)大風沙(sha)地區變壓(ya)(ya)(ya)器(qi)材料的結(jie)構(gou)及(ji)(ji)工藝研(yan)(yan)究、高(gao)寒及(ji)(ji)大風沙(sha)地區變壓(ya)(ya)(ya)器(qi)主要組件的選用(yong)及(ji)(ji)防護措施研(yan)(yan)究、高(gao)寒地區變壓(ya)(ya)(ya)器(qi)低溫啟動方案的研(yan)(yan)究，這一(yi)系列(lie)技術成(cheng)(cheng)果進一(yi)步提升了我國(guo)特(te)高(gao)壓(ya)(ya)(ya)變壓(ya)(ya)(ya)器(qi)設(she)計、工藝及(ji)(ji)制(zhi)造(zao)水平。

蒙西-天津南1000kV特高(gao)壓交流工程首臺雙(shuang)百萬變壓器(qi)(qi)順利通過(guo)試(shi)驗，為(wei)該工程后(hou)續6臺雙(shuang)百萬變壓器(qi)(qi)產品(pin)(pin)和11臺特高(gao)壓電(dian)抗(kang)器(qi)(qi)產品(pin)(pin)完成制造及通過(guo)試(shi)驗奠定了堅實基礎。
