9月15日23時，向家壩—上海±800千(qian)伏特(te)高壓直(zhi)流(liu)(liu)輸電示范工程(cheng)奉賢(xian)換(huan)流(liu)(liu)站首(shou)臺800千(qian)伏特(te)高壓換(huan)流(liu)(liu)變壓器，順利通過現場交接局部放電試(shi)驗。
承擔試(shi)(shi)驗(yan)任務的華(hua)東電(dian)(dian)(dian)(dian)力(li)(li)(li)試(shi)(shi)驗(yan)研(yan)(yan)究(jiu)(jiu)院(yuan)(yuan)，先(xian)期對局(ju)部放(fang)電(dian)(dian)(dian)(dian)測量診斷、分壓器(qi)校(xiao)準、功率測量、油化分析等(deng)過(guo)程進行了聯合(he)(he)測試(shi)(shi)。在國(guo)家電(dian)(dian)(dian)(dian)網公(gong)司(si)直流(liu)建設分公(gong)司(si)的統一協(xie)調下，經湖南電(dian)(dian)(dian)(dian)力(li)(li)(li)建設監(jian)理公(gong)司(si)、安徽送變(bian)(bian)電(dian)(dian)(dian)(dian)公(gong)司(si)、中國(guo)電(dian)(dian)(dian)(dian)力(li)(li)(li)科(ke)(ke)學研(yan)(yan)究(jiu)(jiu)院(yuan)(yuan)、山西省電(dian)(dian)(dian)(dian)力(li)(li)(li)科(ke)(ke)學研(yan)(yan)究(jiu)(jiu)院(yuan)(yuan)等(deng)單位全(quan)力(li)(li)(li)協(xie)助，華(hua)東電(dian)(dian)(dian)(dian)力(li)(li)(li)試(shi)(shi)驗(yan)研(yan)(yan)究(jiu)(jiu)院(yuan)(yuan)試(shi)(shi)驗(yan)組(zu)于(yu)7月(yue)上旬，對試(shi)(shi)驗(yan)回路進行了反復調試(shi)(shi)，確保(bao)試(shi)(shi)驗(yan)萬無一失。世界首(shou)臺800千伏(fu)特高壓換(huan)流(liu)變(bian)(bian)壓器(qi)運(yun)抵奉賢換(huan)流(liu)站現(xian)場后，華(hua)東電(dian)(dian)(dian)(dian)力(li)(li)(li)試(shi)(shi)驗(yan)研(yan)(yan)究(jiu)(jiu)院(yuan)(yuan)于(yu)9月(yue)14日進行了常規(gui)試(shi)(shi)驗(yan)，9月(yue)15日22時，換(huan)流(liu)變(bian)(bian)壓器(qi)現(xian)場局(ju)部放(fang)電(dian)(dian)(dian)(dian)試(shi)(shi)驗(yan)閥側(ce)施(shi)壓開(kai)始，試(shi)(shi)驗(yan)電(dian)(dian)(dian)(dian)壓下監(jian)測到換(huan)流(liu)變(bian)(bian)壓器(qi)閥側(ce)、網側(ce)的局(ju)部放(fang)電(dian)(dian)(dian)(dian)量均符(fu)合(he)(he)標準要(yao)求。
首(shou)(shou)臺800千伏(fu)特高(gao)壓換流(liu)變壓器局部放電試(shi)驗(yan)(yan)成功，標(biao)(biao)志著特高(gao)壓直流(liu)輸電示范工(gong)(gong)程(cheng)核心主設備(bei)安裝、試(shi)驗(yan)(yan)工(gong)(gong)作首(shou)(shou)戰告捷，為實現奉(feng)賢換流(liu)站年(nian)底帶電投(tou)運(yun)目標(biao)(biao)打下堅實基礎(chu)。
