9月(yue)15日23時，向家壩—上海±800千(qian)伏特(te)高壓直流(liu)輸(shu)電示(shi)范工程(cheng)奉賢換流(liu)站(zhan)首(shou)臺800千(qian)伏特(te)高壓換流(liu)變壓器，順利(li)通(tong)過(guo)現場交接局部放電試(shi)驗(yan)。
承(cheng)擔試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)任務的(de)華(hua)東(dong)電(dian)(dian)(dian)力(li)(li)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)研(yan)(yan)究(jiu)(jiu)院(yuan)，先期對局部放電(dian)(dian)(dian)測(ce)(ce)量(liang)診斷、分壓(ya)(ya)器(qi)(qi)校準、功率測(ce)(ce)量(liang)、油化(hua)分析(xi)等過程(cheng)進(jin)行了聯合測(ce)(ce)試(shi)(shi)(shi)(shi)(shi)。在(zai)國家(jia)電(dian)(dian)(dian)網公司直流建(jian)設(she)(she)分公司的(de)統一(yi)協調(diao)下，經(jing)湖南電(dian)(dian)(dian)力(li)(li)建(jian)設(she)(she)監理(li)公司、安徽送(song)變(bian)電(dian)(dian)(dian)公司、中國電(dian)(dian)(dian)力(li)(li)科學研(yan)(yan)究(jiu)(jiu)院(yuan)、山西(xi)省電(dian)(dian)(dian)力(li)(li)科學研(yan)(yan)究(jiu)(jiu)院(yuan)等單位(wei)全力(li)(li)協助，華(hua)東(dong)電(dian)(dian)(dian)力(li)(li)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)研(yan)(yan)究(jiu)(jiu)院(yuan)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)組于7月上旬，對試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)回路進(jin)行了反復調(diao)試(shi)(shi)(shi)(shi)(shi)，確保試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)萬無一(yi)失。世界(jie)首臺800千伏特高壓(ya)(ya)換流變(bian)壓(ya)(ya)器(qi)(qi)運抵(di)奉(feng)賢換流站現(xian)場(chang)后，華(hua)東(dong)電(dian)(dian)(dian)力(li)(li)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)研(yan)(yan)究(jiu)(jiu)院(yuan)于9月14日進(jin)行了常規試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)，9月15日22時(shi)，換流變(bian)壓(ya)(ya)器(qi)(qi)現(xian)場(chang)局部放電(dian)(dian)(dian)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)閥側施壓(ya)(ya)開始，試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)電(dian)(dian)(dian)壓(ya)(ya)下監測(ce)(ce)到換流變(bian)壓(ya)(ya)器(qi)(qi)閥側、網側的(de)局部放電(dian)(dian)(dian)量(liang)均(jun)符合標(biao)準要(yao)求。
首(shou)臺(tai)800千伏特高壓換流變(bian)壓器(qi)局(ju)部放電試(shi)驗成功，標(biao)志著特高壓直流輸電示范工程(cheng)核心主設備安裝(zhuang)、試(shi)驗工作(zuo)首(shou)戰告捷(jie)，為實(shi)現奉賢(xian)換流站年底帶電投(tou)運目標(biao)打下堅實(shi)基礎。
