9月15日(ri)23時，向家壩—上海±800千伏特(te)(te)高(gao)壓直流(liu)輸電示范工程奉(feng)賢換流(liu)站(zhan)首臺800千伏特(te)(te)高(gao)壓換流(liu)變壓器(qi)，順利通過現場交接局(ju)部放(fang)電試(shi)驗。
承擔(dan)試(shi)(shi)驗(yan)任務的華東(dong)電(dian)(dian)力(li)試(shi)(shi)驗(yan)研(yan)究(jiu)(jiu)(jiu)院(yuan)(yuan)，先期(qi)對局部(bu)放電(dian)(dian)測量診斷、分壓(ya)(ya)器(qi)(qi)校準(zhun)、功率測量、油化分析等過程進(jin)(jin)行了(le)聯合測試(shi)(shi)。在國(guo)家電(dian)(dian)網(wang)公(gong)司直(zhi)流(liu)建(jian)設(she)(she)分公(gong)司的統一(yi)協調下(xia)，經(jing)湖南電(dian)(dian)力(li)建(jian)設(she)(she)監(jian)理(li)公(gong)司、安徽送(song)變電(dian)(dian)公(gong)司、中國(guo)電(dian)(dian)力(li)科學研(yan)究(jiu)(jiu)(jiu)院(yuan)(yuan)、山西省(sheng)電(dian)(dian)力(li)科學研(yan)究(jiu)(jiu)(jiu)院(yuan)(yuan)等單位(wei)全力(li)協助(zhu)，華東(dong)電(dian)(dian)力(li)試(shi)(shi)驗(yan)研(yan)究(jiu)(jiu)(jiu)院(yuan)(yuan)試(shi)(shi)驗(yan)組于7月上旬，對試(shi)(shi)驗(yan)回(hui)路進(jin)(jin)行了(le)反復(fu)調試(shi)(shi)，確保試(shi)(shi)驗(yan)萬無一(yi)失(shi)。世界(jie)首臺800千伏特(te)高壓(ya)(ya)換流(liu)變壓(ya)(ya)器(qi)(qi)運抵(di)奉賢換流(liu)站現場(chang)后，華東(dong)電(dian)(dian)力(li)試(shi)(shi)驗(yan)研(yan)究(jiu)(jiu)(jiu)院(yuan)(yuan)于9月14日進(jin)(jin)行了(le)常規(gui)試(shi)(shi)驗(yan)，9月15日22時(shi)，換流(liu)變壓(ya)(ya)器(qi)(qi)現場(chang)局部(bu)放電(dian)(dian)試(shi)(shi)驗(yan)閥側施壓(ya)(ya)開始，試(shi)(shi)驗(yan)電(dian)(dian)壓(ya)(ya)下(xia)監(jian)測到換流(liu)變壓(ya)(ya)器(qi)(qi)閥側、網(wang)側的局部(bu)放電(dian)(dian)量均符合標(biao)準(zhun)要求。
首臺800千伏特(te)高(gao)壓(ya)換流(liu)變(bian)壓(ya)器局部放電試(shi)驗成功，標(biao)志著特(te)高(gao)壓(ya)直流(liu)輸電示范工程核心主設備(bei)安裝(zhuang)、試(shi)驗工作首戰告捷，為實(shi)現奉賢換流(liu)站(zhan)年底帶電投運(yun)目標(biao)打(da)下堅實(shi)基礎。
