近日(ri)，由中(zhong)國(guo)西電(dian)設計制(zhi)造的蒙西-天津南特高壓(ya)交流工程(cheng)(cheng)首(shou)臺(tai)1000kV 1000MVA電(dian)力變壓(ya)器順利通過試(shi)驗，各項(xiang)性能指標(biao)達到或(huo)優于(yu)國(guo)家標(biao)準和技術協議要求，標(biao)志(zhi)著(zhu)該工程(cheng)(cheng)首(shou)臺(tai)雙百萬變壓(ya)器在(zai)中(zhong)國(guo)西電(dian)研制(zhi)成功。
蒙(meng)西(xi)(xi)-天(tian)津南1000千伏特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)交(jiao)流(liu)輸變(bian)電(dian)(dian)(dian)工(gong)(gong)程(cheng)(cheng)是(shi)國(guo)家電(dian)(dian)(dian)網華北特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)交(jiao)直流(liu)主網架(jia)的(de)(de)重要組成部分。2015年，中(zhong)國(guo)西(xi)(xi)電(dian)(dian)(dian)成功(gong)中(zhong)標(biao)蒙(meng)西(xi)(xi)-天(tian)津南特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)交(jiao)流(liu)工(gong)(gong)程(cheng)(cheng)蒙(meng)西(xi)(xi)變(bian)電(dian)(dian)(dian)站7臺(tai)雙(shuang)百萬(wan)變(bian)壓(ya)(ya)(ya)(ya)器(qi)和晉北變(bian)電(dian)(dian)(dian)站11臺(tai)特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)抗器(qi)，是(shi)該(gai)(gai)批次特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)招(zhao)標(biao)項目中(zhong)中(zhong)標(biao)份(fen)額最大的(de)(de)變(bian)壓(ya)(ya)(ya)(ya)器(qi)廠家。該(gai)(gai)工(gong)(gong)程(cheng)(cheng)是(shi)中(zhong)國(guo)西(xi)(xi)電(dian)(dian)(dian)繼晉東(dong)南-南陽-荊門特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)示范工(gong)(gong)程(cheng)(cheng)、皖電(dian)(dian)(dian)東(dong)送(song)特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)交(jiao)流(liu)示范工(gong)(gong)程(cheng)(cheng)、浙北-福州特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)工(gong)(gong)程(cheng)(cheng)、淮南-上海(hai)特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)工(gong)(gong)程(cheng)(cheng)、錫盟-山東(dong)特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)工(gong)(gong)程(cheng)(cheng)之后，成功(gong)中(zhong)標(biao)的(de)(de)又一(yi)特(te)(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)重點工(gong)(gong)程(cheng)(cheng)。
“蒙西-天津(jin)南(nan)1000kV特(te)(te)高(gao)壓交流工(gong)程”與(yu)先期建設的(de)(de)(de)特(te)(te)高(gao)壓交流工(gong)程相比較(jiao)，蒙西1000kV變(bian)電站處于大風(feng)沙地區，揚沙現象(xiang)較(jiao)多，且有出現沙塵暴的(de)(de)(de)可(ke)能(neng),同時(shi)現場最低(di)環境溫度達-30.9℃，運行條件惡劣，對特(te)(te)高(gao)壓自耦變(bian)壓器的(de)(de)(de)安全可(ke)靠運行是(shi)極(ji)大的(de)(de)(de)考驗(yan)，因此防風(feng)沙及低(di)溫啟動的(de)(de)(de)研(yan)究是(shi)本次設計的(de)(de)(de)關(guan)鍵(jian)。
設計人員在沿(yan)用前期特(te)高壓產(chan)品(pin)成(cheng)熟(shu)結(jie)構(gou)，進一步推動國產(chan)化的同時(shi)，進行科研(yan)攻關、自主創新。完成(cheng)了(le)高寒(han)及(ji)大(da)風沙地區(qu)變(bian)壓器(qi)材料的結(jie)構(gou)及(ji)工(gong)(gong)藝研(yan)究、高寒(han)及(ji)大(da)風沙地區(qu)變(bian)壓器(qi)主要組件的選用及(ji)防護措施研(yan)究、高寒(han)地區(qu)變(bian)壓器(qi)低溫啟(qi)動方(fang)案的研(yan)究，這(zhe)一系(xi)列技術成(cheng)果進一步提(ti)升了(le)我(wo)國特(te)高壓變(bian)壓器(qi)設計、工(gong)(gong)藝及(ji)制造水平。
蒙西(xi)-天津南1000kV特(te)高壓交(jiao)流工(gong)程首臺雙百萬(wan)變壓器順利通過試驗(yan)，為該工(gong)程后續6臺雙百萬(wan)變壓器產品和11臺特(te)高壓電抗器產品完成制造及通過試驗(yan)奠定了堅實基礎。
