　　2009年11月17日，向家(jia)壩-上(shang)海±800千(qian)伏(fu)特(te)高(gao)壓(ya)直(zhi)流(liu)(liu)(liu)示范工(gong)程(cheng)復龍(long)站(zhan)800千(qian)伏(fu)高(gao)端換流(liu)(liu)(liu)變(bian)(bian)壓(ya)器(qi)(qi)在西(xi)門子紐倫(lun)堡變(bian)(bian)壓(ya)器(qi)(qi)廠成(cheng)功通過全部型(xing)式試驗項目考(kao)核，各項技術指標完全滿足技術規范要求，至此，特(te)高(gao)壓(ya)直(zhi)流(liu)(liu)(liu)示范工(gong)程(cheng)兩端換流(liu)(liu)(liu)站(zhan)所有800千(qian)伏(fu)直(zhi)流(liu)(liu)(liu)設(she)備全部通過型(xing)式試驗考(kao)核，標志著(zhu)復龍(long)站(zhan)換流(liu)(liu)(liu)變(bian)(bian)壓(ya)器(qi)(qi)即將(jiang)進入批量制造和交付，為加快工(gong)程(cheng)建設(she)進度，實(shi)現工(gong)程(cheng)建設(she)目標奠定了堅實(shi)基礎。

　　國家(jia)(jia)電(dian)網公司高(gao)(gao)度重視西門(men)子(zi)特(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)直(zhi)流(liu)換(huan)流(liu)變(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)的(de)(de)研制(zhi)，公司領(ling)導密(mi)切(qie)關注研制(zhi)進(jin)展，多(duo)次作出(chu)重要批示。特(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)部(bu)全力以(yi)赴，精心組織國內外資深換(huan)流(liu)變(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)專家(jia)(jia)，深入剖析、研討西門(men)子(zi)其他(ta)特(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)直(zhi)流(liu)工(gong)(gong)程換(huan)流(liu)變(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)局放偏大、產(chan)氣等(deng)(deng)問題的(de)(de)根源，全面(mian)(mian)、詳(xiang)細、嚴格(ge)地審核閥側出(chu)線裝置、主，縱絕緣，調壓(ya)(ya)(ya)(ya)(ya)(ya)出(chu)線，分接開關等(deng)(deng)方(fang)面(mian)(mian)的(de)(de)設計方(fang)案以(yi)及干燥、真(zhen)空抽取(qu)、注油及熱油循環(huan)、靜置等(deng)(deng)后(hou)期工(gong)(gong)藝方(fang)案和(he)指(zhi)標，集中(zhong)國內外變(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)行業的(de)(de)智慧，充分借(jie)鑒(jian)各(ge)類變(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)研制(zhi)的(de)(de)經(jing)驗(yan)(yan)，提出(chu)多(duo)項(xiang)技術改(gai)進(jin)建議(yi)和(he)工(gong)(gong)藝改(gai)進(jin)措施，并(bing)與西門(men)子(zi)專家(jia)(jia)達成共識。同(tong)時，特(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)部(bu)赴西門(men)子(zi)紐倫堡廠全方(fang)位管控換(huan)流(liu)變(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)研制(zhi)，狠抓改(gai)進(jin)措施落實，敦促(cu)廠家(jia)(jia)采(cai)用性能(neng)更為先進(jin)的(de)(de)真(zhen)空泵等(deng)(deng)工(gong)(gong)藝處理設備，延長工(gong)(gong)藝處理時間，實現(xian)了(le)更嚴格(ge)的(de)(de)工(gong)(gong)藝控制(zhi)指(zhi)標，全面(mian)(mian)提升了(le)換(huan)流(liu)變(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)質(zhi)量(liang)，完全消(xiao)除(chu)產(chan)氣、局放偏大等(deng)(deng)問題。型式試驗(yan)(yan)考核結(jie)果顯示，該臺換(huan)流(liu)變(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)是西門(men)子(zi)各(ge)項(xiang)技術指(zhi)標最優良、最穩定的(de)(de)特(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)直(zhi)流(liu)換(huan)流(liu)變(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)。

　　通過特(te)高(gao)(gao)壓(ya)(ya)(ya)直流示(shi)范工程建設(she)(she)，國家(jia)電網(wang)公司組織國內外廠家(jia)研(yan)(yan)(yan)制成功了(le)(le)兩種技(ji)術路線(xian)的(de)800千伏(fu)特(te)高(gao)(gao)壓(ya)(ya)(ya)直流換流變壓(ya)(ya)(ya)器，進(jin)一步深入驗(yan)證了(le)(le)特(te)高(gao)(gao)壓(ya)(ya)(ya)直流輸(shu)電技(ji)術的(de)可(ke)行性，加快了(le)(le)特(te)高(gao)(gao)壓(ya)(ya)(ya)直流輸(shu)電技(ji)術的(de)推(tui)廣應用的(de)步伐，為今后更高(gao)(gao)電壓(ya)(ya)(ya)等(deng)級的(de)特(te)高(gao)(gao)壓(ya)(ya)(ya)直流輸(shu)電技(ji)術研(yan)(yan)(yan)究和設(she)(she)備研(yan)(yan)(yan)制奠定了(le)(le)堅實(shi)基礎。
