9月15日(ri)23時，向(xiang)家(jia)壩—上(shang)海±800千伏(fu)特(te)高壓直流(liu)輸電(dian)示范工程奉賢(xian)換(huan)(huan)流(liu)站首臺800千伏(fu)特(te)高壓換(huan)(huan)流(liu)變壓器，順(shun)利(li)通過現場(chang)交接局部放(fang)電(dian)試(shi)驗。
承擔試(shi)驗(yan)(yan)(yan)任(ren)務的華(hua)東(dong)(dong)電(dian)(dian)(dian)(dian)力(li)(li)試(shi)驗(yan)(yan)(yan)研(yan)究院(yuan)，先期對(dui)局(ju)部(bu)放電(dian)(dian)(dian)(dian)測量診斷、分(fen)壓器(qi)(qi)校準、功率測量、油化分(fen)析等(deng)過程(cheng)進(jin)行(xing)(xing)了聯合(he)測試(shi)。在(zai)國家電(dian)(dian)(dian)(dian)網公(gong)司(si)(si)直流(liu)建(jian)設(she)(she)分(fen)公(gong)司(si)(si)的統一協(xie)調下(xia)，經湖南電(dian)(dian)(dian)(dian)力(li)(li)建(jian)設(she)(she)監(jian)(jian)理公(gong)司(si)(si)、安徽送變電(dian)(dian)(dian)(dian)公(gong)司(si)(si)、中國電(dian)(dian)(dian)(dian)力(li)(li)科學研(yan)究院(yuan)、山西省(sheng)電(dian)(dian)(dian)(dian)力(li)(li)科學研(yan)究院(yuan)等(deng)單(dan)位(wei)全力(li)(li)協(xie)助，華(hua)東(dong)(dong)電(dian)(dian)(dian)(dian)力(li)(li)試(shi)驗(yan)(yan)(yan)研(yan)究院(yuan)試(shi)驗(yan)(yan)(yan)組于(yu)7月(yue)上旬，對(dui)試(shi)驗(yan)(yan)(yan)回路進(jin)行(xing)(xing)了反復(fu)調試(shi)，確保試(shi)驗(yan)(yan)(yan)萬無(wu)一失。世界(jie)首(shou)臺800千伏特高(gao)壓換流(liu)變壓器(qi)(qi)運抵奉賢換流(liu)站現場(chang)后，華(hua)東(dong)(dong)電(dian)(dian)(dian)(dian)力(li)(li)試(shi)驗(yan)(yan)(yan)研(yan)究院(yuan)于(yu)9月(yue)14日進(jin)行(xing)(xing)了常規試(shi)驗(yan)(yan)(yan)，9月(yue)15日22時，換流(liu)變壓器(qi)(qi)現場(chang)局(ju)部(bu)放電(dian)(dian)(dian)(dian)試(shi)驗(yan)(yan)(yan)閥側(ce)(ce)施壓開始，試(shi)驗(yan)(yan)(yan)電(dian)(dian)(dian)(dian)壓下(xia)監(jian)(jian)測到(dao)換流(liu)變壓器(qi)(qi)閥側(ce)(ce)、網側(ce)(ce)的局(ju)部(bu)放電(dian)(dian)(dian)(dian)量均符合(he)標準要(yao)求。
首(shou)臺(tai)800千伏特高壓(ya)換(huan)流(liu)變壓(ya)器(qi)局部(bu)放電(dian)試驗(yan)(yan)成(cheng)功，標志著特高壓(ya)直流(liu)輸(shu)電(dian)示范工(gong)程核心主(zhu)設(she)備安裝、試驗(yan)(yan)工(gong)作首(shou)戰告捷(jie)，為實現奉賢換(huan)流(liu)站年底(di)帶電(dian)投運目標打下(xia)堅實基(ji)礎。
