9月15日23時，向家壩—上海±800千伏(fu)特高壓直(zhi)流(liu)輸電(dian)示范工程(cheng)奉賢換流(liu)站首臺800千伏(fu)特高壓換流(liu)變壓器，順利通過現場(chang)交接局部放電(dian)試驗。
承擔試(shi)(shi)(shi)(shi)驗(yan)(yan)任務的(de)華(hua)(hua)東電(dian)(dian)力(li)(li)試(shi)(shi)(shi)(shi)驗(yan)(yan)研(yan)究院(yuan)，先(xian)期對(dui)局(ju)部(bu)放電(dian)(dian)測量(liang)診斷、分壓(ya)(ya)器校準、功率測量(liang)、油化分析等過程進行了(le)(le)聯合(he)測試(shi)(shi)(shi)(shi)。在國家電(dian)(dian)網公(gong)司(si)(si)直流(liu)(liu)建設分公(gong)司(si)(si)的(de)統一協調下，經湖南電(dian)(dian)力(li)(li)建設監(jian)理公(gong)司(si)(si)、安徽送(song)變(bian)電(dian)(dian)公(gong)司(si)(si)、中(zhong)國電(dian)(dian)力(li)(li)科(ke)學研(yan)究院(yuan)、山西省電(dian)(dian)力(li)(li)科(ke)學研(yan)究院(yuan)等單位(wei)全力(li)(li)協助，華(hua)(hua)東電(dian)(dian)力(li)(li)試(shi)(shi)(shi)(shi)驗(yan)(yan)研(yan)究院(yuan)試(shi)(shi)(shi)(shi)驗(yan)(yan)組于7月(yue)上旬，對(dui)試(shi)(shi)(shi)(shi)驗(yan)(yan)回路進行了(le)(le)反復調試(shi)(shi)(shi)(shi)，確保(bao)試(shi)(shi)(shi)(shi)驗(yan)(yan)萬無一失。世界首臺(tai)800千(qian)伏特高(gao)壓(ya)(ya)換流(liu)(liu)變(bian)壓(ya)(ya)器運(yun)抵奉(feng)賢(xian)換流(liu)(liu)站現場(chang)(chang)后，華(hua)(hua)東電(dian)(dian)力(li)(li)試(shi)(shi)(shi)(shi)驗(yan)(yan)研(yan)究院(yuan)于9月(yue)14日進行了(le)(le)常規試(shi)(shi)(shi)(shi)驗(yan)(yan)，9月(yue)15日22時，換流(liu)(liu)變(bian)壓(ya)(ya)器現場(chang)(chang)局(ju)部(bu)放電(dian)(dian)試(shi)(shi)(shi)(shi)驗(yan)(yan)閥(fa)側施(shi)壓(ya)(ya)開始，試(shi)(shi)(shi)(shi)驗(yan)(yan)電(dian)(dian)壓(ya)(ya)下監(jian)測到換流(liu)(liu)變(bian)壓(ya)(ya)器閥(fa)側、網側的(de)局(ju)部(bu)放電(dian)(dian)量(liang)均符合(he)標準要求。
首(shou)臺800千伏特(te)高壓(ya)(ya)換(huan)流變壓(ya)(ya)器局部放(fang)電(dian)(dian)(dian)試驗成功(gong)，標志著特(te)高壓(ya)(ya)直流輸電(dian)(dian)(dian)示范(fan)工(gong)(gong)程核心(xin)主設備(bei)安裝(zhuang)、試驗工(gong)(gong)作首(shou)戰告捷，為實(shi)現(xian)奉賢換(huan)流站年底帶電(dian)(dian)(dian)投運目標打下堅實(shi)基(ji)礎。
