近(jin)日，中(zhong)國西電為川藏鐵路(lu)拉薩至林(lin)芝段(duan)供電工(gong)程雅中(zhong)（郎縣）、沃卡（拉薩）500千伏(fu)變電站新建工(gong)程制造的(de)500千伏(fu)250兆伏(fu)安單(dan)相(xiang)自耦變壓器一次(ci)性通(tong)過(guo)全部試驗，各項性能指標達到或優于國家(jia)標準和技(ji)術協議的(de)要求。
藏(zang)中聯網(wang)(wang)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)由西(xi)藏(zang)藏(zang)中和昌都電(dian)(dian)(dian)網(wang)(wang)聯網(wang)(wang)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)、川(chuan)藏(zang)鐵路拉薩至(zhi)林(lin)芝(zhi)段供電(dian)(dian)(dian)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)組成，起于西(xi)藏(zang)昌都市(shi)(shi)芒康縣，止(zhi)于山南市(shi)(shi)桑日縣，跨(kua)越西(xi)藏(zang)三(san)(san)地市(shi)(shi)十區縣，計劃新建(jian)、擴建(jian)110千伏(fu)及以(yi)上(shang)(shang)變電(dian)(dian)(dian)站16座，新建(jian)110千伏(fu)及以(yi)上(shang)(shang)線路2738公里(li)。該工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)是繼2011年青(qing)藏(zang)、2014年川(chuan)藏(zang)兩大輸電(dian)(dian)(dian)聯網(wang)(wang)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)投運后，第三(san)(san)條建(jian)設的超(chao)高壓500千伏(fu)電(dian)(dian)(dian)力天路，也(ye)是目(mu)前世(shi)界上(shang)(shang)海拔(ba)最(zui)高、跨(kua)度最(zui)大、自然條件最(zui)復雜的世(shi)界級輸電(dian)(dian)(dian)聯網(wang)(wang)建(jian)設工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)。該工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)是實現西(xi)藏(zang)“十三(san)(san)五”跨(kua)越式發展(zhan)、關系富民(min)興(xing)藏(zang)大局的戰略工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)和民(min)心工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)，是突破生命禁區、挑戰生存(cun)極限、超(chao)高海拔(ba)、超(chao)大高差、自然條件最(zui)復雜、建(jian)設難度空前的“超(chao)級”輸變電(dian)(dian)(dian)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)。該工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)建(jian)設對(dui)構建(jian)堅強西(xi)藏(zang)電(dian)(dian)(dian)網(wang)(wang)網(wang)(wang)架，促進清(qing)潔(jie)能源開發外送(song)，增(zeng)進民(min)族團(tuan)結具有重(zhong)大意義。
在藏中聯網(wang)項(xiang)目(mu)(mu)中，中國西(xi)電(dian)共承(cheng)擔了12臺500千伏(fu)(fu)單相自耦變(bian)壓(ya)器的制(zhi)造任務(wu)。該項(xiang)目(mu)(mu)產品均用于海(hai)(hai)拔高度3500米以上、極(ji)端氣(qi)溫-45℃，具有(you)容量大、高電(dian)壓(ya)、高海(hai)(hai)拔、晝夜溫差大、耐嚴寒、運輸困難(nan)等特點(dian)。此(ci)次制(zhi)造成功的500千伏(fu)(fu)變(bian)壓(ya)器，既是這批產品的首(shou)臺產品，也是該司為西(xi)藏地(di)區提供的首(shou)臺500千伏(fu)(fu)高電(dian)壓(ya)等級的變(bian)壓(ya)器。
