近日，中國西電為川藏鐵路拉薩至林芝段(duan)供電工程雅中（郎(lang)縣）、沃卡(ka)（拉薩）500千伏(fu)變(bian)電站新建(jian)工程制(zhi)造的500千伏(fu)250兆(zhao)伏(fu)安單相自耦變(bian)壓器一次(ci)性通過全部試驗(yan)，各(ge)項(xiang)性能指標達(da)到或優于國家標準和(he)技(ji)術協議的要(yao)求(qiu)。
藏(zang)中聯(lian)(lian)網(wang)工(gong)(gong)(gong)程(cheng)由西(xi)(xi)藏(zang)藏(zang)中和(he)昌都電(dian)(dian)網(wang)聯(lian)(lian)網(wang)工(gong)(gong)(gong)程(cheng)、川藏(zang)鐵(tie)路拉薩至林芝段(duan)供(gong)電(dian)(dian)工(gong)(gong)(gong)程(cheng)組成(cheng)，起于西(xi)(xi)藏(zang)昌都市芒康縣，止于山南市桑(sang)日(ri)縣，跨(kua)(kua)(kua)越西(xi)(xi)藏(zang)三(san)地市十(shi)區(qu)縣，計(ji)劃新建(jian)(jian)(jian)、擴建(jian)(jian)(jian)110千(qian)伏及以上變(bian)電(dian)(dian)站(zhan)16座，新建(jian)(jian)(jian)110千(qian)伏及以上線(xian)路2738公里。該工(gong)(gong)(gong)程(cheng)是繼(ji)2011年青藏(zang)、2014年川藏(zang)兩大(da)輸電(dian)(dian)聯(lian)(lian)網(wang)工(gong)(gong)(gong)程(cheng)投(tou)運后，第三(san)條建(jian)(jian)(jian)設(she)(she)(she)的(de)超高(gao)壓500千(qian)伏電(dian)(dian)力天路，也是目(mu)前世界上海(hai)拔最(zui)高(gao)、跨(kua)(kua)(kua)度最(zui)大(da)、自(zi)然條件(jian)最(zui)復雜(za)(za)的(de)世界級輸電(dian)(dian)聯(lian)(lian)網(wang)建(jian)(jian)(jian)設(she)(she)(she)工(gong)(gong)(gong)程(cheng)。該工(gong)(gong)(gong)程(cheng)是實現(xian)西(xi)(xi)藏(zang)“十(shi)三(san)五”跨(kua)(kua)(kua)越式發展、關系(xi)富民興(xing)藏(zang)大(da)局的(de)戰略工(gong)(gong)(gong)程(cheng)和(he)民心工(gong)(gong)(gong)程(cheng)，是突破(po)生(sheng)命禁區(qu)、挑戰生(sheng)存極限、超高(gao)海(hai)拔、超大(da)高(gao)差、自(zi)然條件(jian)最(zui)復雜(za)(za)、建(jian)(jian)(jian)設(she)(she)(she)難度空前的(de)“超級”輸變(bian)電(dian)(dian)工(gong)(gong)(gong)程(cheng)。該工(gong)(gong)(gong)程(cheng)建(jian)(jian)(jian)設(she)(she)(she)對(dui)構(gou)建(jian)(jian)(jian)堅強西(xi)(xi)藏(zang)電(dian)(dian)網(wang)網(wang)架，促(cu)進清潔能(neng)源開發外(wai)送，增進民族團結(jie)具有重大(da)意義。
在藏中(zhong)聯網項目中(zhong)，中(zhong)國西電共承擔(dan)了12臺500千(qian)(qian)(qian)伏(fu)單(dan)相自耦(ou)變壓器(qi)的(de)制(zhi)造任務。該項目產品(pin)均用于海拔(ba)高(gao)度3500米以上、極端(duan)氣(qi)溫-45℃，具有(you)容(rong)量大、高(gao)電壓、高(gao)海拔(ba)、晝夜溫差大、耐嚴寒、運輸困難等特點。此次制(zhi)造成(cheng)功的(de)500千(qian)(qian)(qian)伏(fu)變壓器(qi)，既是(shi)這批產品(pin)的(de)首臺產品(pin)，也是(shi)該司為(wei)西藏地區提供的(de)首臺500千(qian)(qian)(qian)伏(fu)高(gao)電壓等級(ji)的(de)變壓器(qi)。
