2009年(nian)11月17日，向家壩-上海(hai)±800千伏特高(gao)壓(ya)直流(liu)(liu)示范工(gong)(gong)程(cheng)復龍站(zhan)(zhan)800千伏高(gao)端(duan)換流(liu)(liu)變壓(ya)器(qi)在西門子紐倫堡變壓(ya)器(qi)廠成功通過全(quan)(quan)部型式試驗項目考核，各項技(ji)術指標完全(quan)(quan)滿足技(ji)術規范要求，至此，特高(gao)壓(ya)直流(liu)(liu)示范工(gong)(gong)程(cheng)兩端(duan)換流(liu)(liu)站(zhan)(zhan)所有800千伏直流(liu)(liu)設(she)備全(quan)(quan)部通過型式試驗考核，標志著復龍站(zhan)(zhan)換流(liu)(liu)變壓(ya)器(qi)即將(jiang)進入批(pi)量(liang)制造和交付，為加快工(gong)(gong)程(cheng)建設(she)進度，實現工(gong)(gong)程(cheng)建設(she)目標奠定(ding)了堅實基礎。
國家電網(wang)公司高(gao)度重(zhong)視西門子(zi)特(te)高(gao)壓(ya)(ya)(ya)(ya)直流(liu)換(huan)流(liu)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器的研(yan)制(zhi)(zhi)，公司領導密切關(guan)注研(yan)制(zhi)(zhi)進展(zhan)，多(duo)次作出(chu)重(zhong)要批示。特(te)高(gao)壓(ya)(ya)(ya)(ya)部全(quan)力以赴，精心(xin)組織國內外資(zi)深(shen)換(huan)流(liu)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器專(zhuan)家，深(shen)入剖(pou)析、研(yan)討西門子(zi)其他特(te)高(gao)壓(ya)(ya)(ya)(ya)直流(liu)工(gong)(gong)程換(huan)流(liu)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器局放偏大、產(chan)氣(qi)等問題的根源，全(quan)面(mian)、詳細、嚴(yan)格地(di)審(shen)核閥側(ce)出(chu)線裝(zhuang)置(zhi)、主，縱絕緣，調壓(ya)(ya)(ya)(ya)出(chu)線，分接開(kai)關(guan)等方(fang)面(mian)的設計(ji)方(fang)案以及干燥、真(zhen)空(kong)抽取(qu)、注油(you)及熱油(you)循環(huan)、靜置(zhi)等后期工(gong)(gong)藝方(fang)案和指標，集中國內外變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器行業(ye)的智慧，充分借(jie)鑒各(ge)類變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器研(yan)制(zhi)(zhi)的經驗(yan)，提出(chu)多(duo)項技術改進建議(yi)和工(gong)(gong)藝改進措施(shi)，并(bing)與西門子(zi)專(zhuan)家達成共識。同(tong)時，特(te)高(gao)壓(ya)(ya)(ya)(ya)部赴西門子(zi)紐(niu)倫(lun)堡廠全(quan)方(fang)位管控換(huan)流(liu)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器研(yan)制(zhi)(zhi)，狠抓改進措施(shi)落實，敦促廠家采用(yong)性能更(geng)(geng)為先進的真(zhen)空(kong)泵等工(gong)(gong)藝處理設備，延(yan)長工(gong)(gong)藝處理時間(jian)，實現了更(geng)(geng)嚴(yan)格的工(gong)(gong)藝控制(zhi)(zhi)指標，全(quan)面(mian)提升了換(huan)流(liu)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器質量(liang)，完全(quan)消除產(chan)氣(qi)、局放偏大等問題。型式(shi)試(shi)驗(yan)考(kao)核結果顯示，該臺換(huan)流(liu)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器是(shi)西門子(zi)各(ge)項技術指標最(zui)優(you)良、最(zui)穩定的特(te)高(gao)壓(ya)(ya)(ya)(ya)直流(liu)換(huan)流(liu)變(bian)(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器。
通過特(te)高(gao)壓(ya)直流示范工(gong)程(cheng)建(jian)設，國家電(dian)(dian)(dian)網公司組織國內外(wai)廠家研制(zhi)成(cheng)功了(le)兩種技術路(lu)線的(de)800千伏特(te)高(gao)壓(ya)直流換流變壓(ya)器，進一步(bu)深(shen)入驗證了(le)特(te)高(gao)壓(ya)直流輸電(dian)(dian)(dian)技術的(de)可行性，加快(kuai)了(le)特(te)高(gao)壓(ya)直流輸電(dian)(dian)(dian)技術的(de)推廣應(ying)用的(de)步(bu)伐，為(wei)今后(hou)更高(gao)電(dian)(dian)(dian)壓(ya)等級的(de)特(te)高(gao)壓(ya)直流輸電(dian)(dian)(dian)技術研究和設備研制(zhi)奠定了(le)堅實基礎。
