9月15日23時(shi)，向家(jia)壩—上海±800千(qian)伏特高壓直流輸電示范工程奉(feng)賢換(huan)(huan)流站首臺800千(qian)伏特高壓換(huan)(huan)流變壓器，順利通過現場交接局部放電試驗。
承擔試(shi)驗(yan)任務(wu)的華(hua)東(dong)電(dian)(dian)(dian)力(li)試(shi)驗(yan)研(yan)究(jiu)院，先期對局(ju)部放電(dian)(dian)(dian)測量(liang)診(zhen)斷、分壓(ya)(ya)器校準(zhun)、功率(lv)測量(liang)、油化分析等過(guo)程進(jin)行(xing)了聯合測試(shi)。在國家電(dian)(dian)(dian)網公司直流建設(she)分公司的統(tong)一協(xie)調下，經湖南電(dian)(dian)(dian)力(li)建設(she)監(jian)理公司、安(an)徽送(song)變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)公司、中國電(dian)(dian)(dian)力(li)科(ke)學研(yan)究(jiu)院、山西省電(dian)(dian)(dian)力(li)科(ke)學研(yan)究(jiu)院等單位全力(li)協(xie)助，華(hua)東(dong)電(dian)(dian)(dian)力(li)試(shi)驗(yan)研(yan)究(jiu)院試(shi)驗(yan)組(zu)于7月(yue)上旬，對試(shi)驗(yan)回路進(jin)行(xing)了反復調試(shi)，確保(bao)試(shi)驗(yan)萬無一失。世界首(shou)臺(tai)800千伏(fu)特(te)高壓(ya)(ya)換流變(bian)(bian)(bian)(bian)壓(ya)(ya)器運(yun)抵奉賢換流站現(xian)場(chang)后，華(hua)東(dong)電(dian)(dian)(dian)力(li)試(shi)驗(yan)研(yan)究(jiu)院于9月(yue)14日(ri)進(jin)行(xing)了常規試(shi)驗(yan)，9月(yue)15日(ri)22時(shi)，換流變(bian)(bian)(bian)(bian)壓(ya)(ya)器現(xian)場(chang)局(ju)部放電(dian)(dian)(dian)試(shi)驗(yan)閥側(ce)施壓(ya)(ya)開始，試(shi)驗(yan)電(dian)(dian)(dian)壓(ya)(ya)下監(jian)測到換流變(bian)(bian)(bian)(bian)壓(ya)(ya)器閥側(ce)、網側(ce)的局(ju)部放電(dian)(dian)(dian)量(liang)均(jun)符(fu)合標準(zhun)要求。
首臺800千(qian)伏特(te)高壓換(huan)流(liu)(liu)變壓器局部放電(dian)試驗成功，標(biao)志著特(te)高壓直流(liu)(liu)輸(shu)電(dian)示范(fan)工程核心主設備(bei)安裝、試驗工作首戰告捷，為實現奉賢換(huan)流(liu)(liu)站年(nian)底帶電(dian)投運目標(biao)打下堅實基礎。
