近(jin)日，由中國西電(dian)集團公司設計(ji)生產(chan)的“ZZLW2-100”特高(gao)壓直流轉(zhuan)換(huan)開(kai)關在晉北——南京工程(cheng)一次(ci)轉(zhuan)換(huan)成(cheng)功，實現(xian)了特高(gao)壓直流輸電(dian)工程(cheng)直流轉(zhuan)換(huan)開(kai)關的首次(ci)國產(chan)化應用(yong)。
作為“西(xi)電(dian)(dian)東(dong)送、北(bei)電(dian)(dian)南供”的重要(yao)工程以及國(guo)家大氣污染(ran)防治(zhi)行(xing)動計劃的重點(dian)輸電(dian)(dian)通道，晉北(bei)——江蘇工程全面采(cai)用我(wo)國(guo)自(zi)主研(yan)發(fa)的特(te)高壓直流輸電(dian)(dian)技術和裝(zhuang)備。工程的建成對于改(gai)善大氣環境質量，帶(dai)動裝(zhuang)備制造(zao)業(ye)轉型升(sheng)級，滿(man)足(zu)華(hua)東(dong)地(di)區用電(dian)(dian)需求(qiu)，支撐國(guo)家能源消(xiao)耗強度降低目標實現等均具(ju)有十分重要(yao)的意義(yi)。
2015年11月，中(zhong)國(guo)(guo)西(xi)電(dian)(dian)(dian)(dian)與國(guo)(guo)家(jia)電(dian)(dian)(dian)(dian)網(wang)公(gong)司簽(qian)訂(ding)了(le)(le)晉北站直(zhi)(zhi)流(liu)轉換開(kai)(kai)關和直(zhi)(zhi)流(liu)旁路(lu)開(kai)(kai)關供(gong)貨合同。自2009年中(zhong)國(guo)(guo)西(xi)電(dian)(dian)(dian)(dian)成功研制直(zhi)(zhi)流(liu)轉換開(kai)(kai)關以(yi)來，從葛南(nan)改造工(gong)(gong)(gong)程(cheng)首(shou)次采用西(xi)電(dian)(dian)(dian)(dian)制造的國(guo)(guo)產(chan)直(zhi)(zhi)流(liu)轉換開(kai)(kai)關開(kai)(kai)始，中(zhong)國(guo)(guo)西(xi)電(dian)(dian)(dian)(dian)研制的直(zhi)(zhi)流(liu)轉換開(kai)(kai)關相繼(ji)在青海(hai)格(ge)爾木(mu)——西(xi)藏(zang)拉薩(sa)±400千伏直(zhi)(zhi)流(liu)工(gong)(gong)(gong)程(cheng)、溪(xi)洛渡(du)——廣東±500千伏同塔雙回直(zhi)(zhi)流(liu)工(gong)(gong)(gong)程(cheng)、廈門柔性直(zhi)(zhi)流(liu)輸電(dian)(dian)(dian)(dian)工(gong)(gong)(gong)程(cheng)、云南(nan)金(jin)沙江中(zhong)游電(dian)(dian)(dian)(dian)站送電(dian)(dian)(dian)(dian)廣西(xi)直(zhi)(zhi)流(liu)工(gong)(gong)(gong)程(cheng)以(yi)及云南(nan)永仁——富寧±500千伏等一系列國(guo)(guo)家(jia)重大(da)直(zhi)(zhi)流(liu)工(gong)(gong)(gong)程(cheng)中(zhong)得到全面應用，為國(guo)(guo)產(chan)特高(gao)壓直(zhi)(zhi)流(liu)工(gong)(gong)(gong)程(cheng)用直(zhi)(zhi)流(liu)轉換開(kai)(kai)關的國(guo)(guo)產(chan)化作出(chu)了(le)(le)積極(ji)貢獻(xian)。
