近(jin)日，由中(zhong)國西電集(ji)團(tuan)公(gong)司設(she)計生產(chan)(chan)的“ZZLW2-100”特高壓直(zhi)流轉(zhuan)(zhuan)換開關(guan)在晉北——南(nan)京(jing)工(gong)程一次(ci)(ci)轉(zhuan)(zhuan)換成功，實現了特高壓直(zhi)流輸電工(gong)程直(zhi)流轉(zhuan)(zhuan)換開關(guan)的首次(ci)(ci)國產(chan)(chan)化應用。
作為“西電(dian)(dian)東(dong)送、北電(dian)(dian)南供”的重(zhong)要工(gong)程以及國家大氣(qi)污染防(fang)治(zhi)行動計劃的重(zhong)點輸電(dian)(dian)通(tong)道，晉北——江蘇(su)工(gong)程全(quan)面采用(yong)我國自(zi)主研發(fa)的特高壓直(zhi)流輸電(dian)(dian)技術和裝備(bei)。工(gong)程的建成(cheng)對于改善大氣(qi)環境(jing)質量(liang)，帶(dai)動裝備(bei)制造業(ye)轉型升級，滿(man)足華東(dong)地區用(yong)電(dian)(dian)需求(qiu)，支撐(cheng)國家能源消耗(hao)強度(du)降低目標(biao)實(shi)現等(deng)均具有十分重(zhong)要的意義。
2015年11月(yue)，中(zhong)國(guo)西(xi)(xi)(xi)電(dian)與國(guo)家電(dian)網公司簽(qian)訂了晉北站直(zhi)流(liu)(liu)(liu)轉(zhuan)(zhuan)換(huan)開(kai)關(guan)和直(zhi)流(liu)(liu)(liu)旁路開(kai)關(guan)供貨合同。自2009年中(zhong)國(guo)西(xi)(xi)(xi)電(dian)成功研制直(zhi)流(liu)(liu)(liu)轉(zhuan)(zhuan)換(huan)開(kai)關(guan)以(yi)來，從葛南改造工(gong)程(cheng)(cheng)首次采用(yong)西(xi)(xi)(xi)電(dian)制造的(de)國(guo)產(chan)直(zhi)流(liu)(liu)(liu)轉(zhuan)(zhuan)換(huan)開(kai)關(guan)開(kai)始，中(zhong)國(guo)西(xi)(xi)(xi)電(dian)研制的(de)直(zhi)流(liu)(liu)(liu)轉(zhuan)(zhuan)換(huan)開(kai)關(guan)相繼在(zai)青海格爾(er)木——西(xi)(xi)(xi)藏(zang)拉薩±400千(qian)伏(fu)直(zhi)流(liu)(liu)(liu)工(gong)程(cheng)(cheng)、溪(xi)洛(luo)渡——廣東±500千(qian)伏(fu)同塔雙回直(zhi)流(liu)(liu)(liu)工(gong)程(cheng)(cheng)、廈門(men)柔性直(zhi)流(liu)(liu)(liu)輸電(dian)工(gong)程(cheng)(cheng)、云南金(jin)沙江中(zhong)游電(dian)站送電(dian)廣西(xi)(xi)(xi)直(zhi)流(liu)(liu)(liu)工(gong)程(cheng)(cheng)以(yi)及云南永仁——富寧±500千(qian)伏(fu)等(deng)一系(xi)列國(guo)家重(zhong)大(da)直(zhi)流(liu)(liu)(liu)工(gong)程(cheng)(cheng)中(zhong)得(de)到全面應用(yong)，為國(guo)產(chan)特高壓直(zhi)流(liu)(liu)(liu)工(gong)程(cheng)(cheng)用(yong)直(zhi)流(liu)(liu)(liu)轉(zhuan)(zhuan)換(huan)開(kai)關(guan)的(de)國(guo)產(chan)化(hua)作出了積極貢獻。
