9月15日23時，向(xiang)家(jia)壩—上(shang)海±800千伏特高(gao)(gao)壓(ya)(ya)直(zhi)流輸電示范工程奉(feng)賢(xian)換(huan)流站首臺800千伏特高(gao)(gao)壓(ya)(ya)換(huan)流變壓(ya)(ya)器，順利通過現場交接(jie)局部放電試驗。
承擔試(shi)驗(yan)(yan)(yan)任務的華東(dong)電(dian)(dian)(dian)力試(shi)驗(yan)(yan)(yan)研(yan)究(jiu)院，先期對局部放(fang)電(dian)(dian)(dian)測(ce)量(liang)診斷、分(fen)壓器(qi)(qi)校準、功(gong)率(lv)測(ce)量(liang)、油化分(fen)析等(deng)過程(cheng)進行了聯合(he)測(ce)試(shi)。在國(guo)家電(dian)(dian)(dian)網公(gong)司直流(liu)建設分(fen)公(gong)司的統一協調下，經湖南電(dian)(dian)(dian)力建設監理公(gong)司、安徽送(song)變電(dian)(dian)(dian)公(gong)司、中國(guo)電(dian)(dian)(dian)力科(ke)學(xue)研(yan)究(jiu)院、山西省電(dian)(dian)(dian)力科(ke)學(xue)研(yan)究(jiu)院等(deng)單位全力協助，華東(dong)電(dian)(dian)(dian)力試(shi)驗(yan)(yan)(yan)研(yan)究(jiu)院試(shi)驗(yan)(yan)(yan)組于(yu)7月上(shang)旬(xun)，對試(shi)驗(yan)(yan)(yan)回路進行了反復調試(shi)，確(que)保試(shi)驗(yan)(yan)(yan)萬(wan)無一失(shi)。世界(jie)首臺800千(qian)伏特高壓換流(liu)變壓器(qi)(qi)運(yun)抵奉賢換流(liu)站現場(chang)(chang)后，華東(dong)電(dian)(dian)(dian)力試(shi)驗(yan)(yan)(yan)研(yan)究(jiu)院于(yu)9月14日進行了常規試(shi)驗(yan)(yan)(yan)，9月15日22時，換流(liu)變壓器(qi)(qi)現場(chang)(chang)局部放(fang)電(dian)(dian)(dian)試(shi)驗(yan)(yan)(yan)閥側(ce)施壓開始，試(shi)驗(yan)(yan)(yan)電(dian)(dian)(dian)壓下監測(ce)到(dao)換流(liu)變壓器(qi)(qi)閥側(ce)、網側(ce)的局部放(fang)電(dian)(dian)(dian)量(liang)均符(fu)合(he)標(biao)準要(yao)求。
首臺800千伏特(te)高(gao)壓(ya)換流變(bian)壓(ya)器(qi)局部(bu)放電試(shi)(shi)驗(yan)成功，標(biao)(biao)志著特(te)高(gao)壓(ya)直流輸電示范工(gong)程核心主設(she)備安裝、試(shi)(shi)驗(yan)工(gong)作首戰(zhan)告(gao)捷，為實(shi)現奉賢換流站年底(di)帶電投運目標(biao)(biao)打下(xia)堅實(shi)基礎。
