9月(yue)15日23時，向家(jia)壩—上海(hai)±800千伏(fu)特(te)(te)高壓(ya)(ya)直流輸電示范工(gong)程奉賢換流站首臺800千伏(fu)特(te)(te)高壓(ya)(ya)換流變(bian)壓(ya)(ya)器，順利通過現(xian)場交接(jie)局(ju)部放(fang)電試驗(yan)。
承(cheng)擔(dan)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)任務(wu)的(de)華東(dong)電力(li)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)研(yan)究(jiu)院(yuan)，先期對局部放(fang)電測(ce)量診斷、分壓(ya)(ya)器(qi)校準、功率測(ce)量、油(you)化分析等過程進(jin)(jin)行(xing)(xing)了聯合測(ce)試(shi)(shi)(shi)(shi)(shi)。在國家電網公司直(zhi)流建設分公司的(de)統(tong)一(yi)(yi)協(xie)調下，經湖(hu)南電力(li)建設監理公司、安徽送變(bian)(bian)電公司、中國電力(li)科(ke)學研(yan)究(jiu)院(yuan)、山(shan)西省電力(li)科(ke)學研(yan)究(jiu)院(yuan)等單位全力(li)協(xie)助，華東(dong)電力(li)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)研(yan)究(jiu)院(yuan)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)組于7月(yue)(yue)上旬，對試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)回路進(jin)(jin)行(xing)(xing)了反復調試(shi)(shi)(shi)(shi)(shi)，確保試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)萬無一(yi)(yi)失。世界首臺800千伏(fu)特高壓(ya)(ya)換流變(bian)(bian)壓(ya)(ya)器(qi)運抵奉賢換流站(zhan)現(xian)(xian)場后，華東(dong)電力(li)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)研(yan)究(jiu)院(yuan)于9月(yue)(yue)14日(ri)進(jin)(jin)行(xing)(xing)了常規(gui)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)，9月(yue)(yue)15日(ri)22時(shi)，換流變(bian)(bian)壓(ya)(ya)器(qi)現(xian)(xian)場局部放(fang)電試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)閥側施壓(ya)(ya)開始，試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)電壓(ya)(ya)下監測(ce)到換流變(bian)(bian)壓(ya)(ya)器(qi)閥側、網側的(de)局部放(fang)電量均符合標準要求(qiu)。
首臺800千(qian)伏特(te)高壓換流(liu)變壓器(qi)局部(bu)放(fang)電(dian)試(shi)驗成功，標(biao)志著特(te)高壓直流(liu)輸(shu)電(dian)示范工(gong)程核(he)心主設備(bei)安(an)裝、試(shi)驗工(gong)作(zuo)首戰告捷(jie)，為實(shi)現奉賢(xian)換流(liu)站年(nian)底帶電(dian)投(tou)運目標(biao)打下堅實(shi)基礎(chu)。
