9月15日(ri)23時，向家壩—上海±800千(qian)伏特高壓直流(liu)輸電示范工程(cheng)奉賢(xian)換流(liu)站首臺800千(qian)伏特高壓換流(liu)變壓器(qi)，順(shun)利(li)通(tong)過現場交接(jie)局部放電試驗。
承擔試(shi)(shi)(shi)(shi)驗(yan)任務(wu)的(de)華(hua)東(dong)電(dian)(dian)(dian)力(li)試(shi)(shi)(shi)(shi)驗(yan)研(yan)究院(yuan)(yuan)，先期對局(ju)部放(fang)電(dian)(dian)(dian)測量診斷(duan)、分壓(ya)器校準、功率(lv)測量、油化(hua)分析等(deng)過程進行(xing)了(le)聯合(he)測試(shi)(shi)(shi)(shi)。在國(guo)家(jia)電(dian)(dian)(dian)網公司(si)直(zhi)流(liu)建(jian)設(she)分公司(si)的(de)統一(yi)協調下，經湖南(nan)電(dian)(dian)(dian)力(li)建(jian)設(she)監理公司(si)、安徽送變(bian)電(dian)(dian)(dian)公司(si)、中國(guo)電(dian)(dian)(dian)力(li)科學研(yan)究院(yuan)(yuan)、山西(xi)省電(dian)(dian)(dian)力(li)科學研(yan)究院(yuan)(yuan)等(deng)單位全力(li)協助，華(hua)東(dong)電(dian)(dian)(dian)力(li)試(shi)(shi)(shi)(shi)驗(yan)研(yan)究院(yuan)(yuan)試(shi)(shi)(shi)(shi)驗(yan)組(zu)于7月(yue)上旬，對試(shi)(shi)(shi)(shi)驗(yan)回路進行(xing)了(le)反復調試(shi)(shi)(shi)(shi)，確(que)保試(shi)(shi)(shi)(shi)驗(yan)萬無(wu)一(yi)失。世界首(shou)臺800千伏特(te)高壓(ya)換流(liu)變(bian)壓(ya)器運抵奉(feng)賢換流(liu)站(zhan)現(xian)場后，華(hua)東(dong)電(dian)(dian)(dian)力(li)試(shi)(shi)(shi)(shi)驗(yan)研(yan)究院(yuan)(yuan)于9月(yue)14日(ri)進行(xing)了(le)常規(gui)試(shi)(shi)(shi)(shi)驗(yan)，9月(yue)15日(ri)22時，換流(liu)變(bian)壓(ya)器現(xian)場局(ju)部放(fang)電(dian)(dian)(dian)試(shi)(shi)(shi)(shi)驗(yan)閥側施壓(ya)開始(shi)，試(shi)(shi)(shi)(shi)驗(yan)電(dian)(dian)(dian)壓(ya)下監測到換流(liu)變(bian)壓(ya)器閥側、網側的(de)局(ju)部放(fang)電(dian)(dian)(dian)量均符合(he)標(biao)準要求。
首(shou)臺800千伏特(te)高(gao)壓換流(liu)變壓器局(ju)部(bu)放電(dian)(dian)試驗(yan)成功，標志(zhi)著特(te)高(gao)壓直流(liu)輸(shu)電(dian)(dian)示范工(gong)程核心主設(she)備安(an)裝(zhuang)、試驗(yan)工(gong)作(zuo)首(shou)戰告捷，為實現奉賢換流(liu)站年底帶電(dian)(dian)投運目標打下堅實基礎。
