11月上旬，多分裂大(da)截面導(dao)線(xian)分次展放施工技術(shu)研(yan)究(jiu)項目正式啟動(dong)。
多分(fen)(fen)裂大截面導線分(fen)(fen)次展放施工技術(shu)研究課題為(wei)國(guo)家電(dian)網公(gong)司科(ke)技項目(mu)(mu)。該項目(mu)(mu)由(you)國(guo)網交流工程建(jian)設有限(xian)公(gong)司負責，北京送變(bian)電(dian)公(gong)司、上海電(dian)纜(lan)研究所分(fen)(fen)別參(can)與(yu)課題施工組織(zhi)與(yu)試驗(yan)分(fen)(fen)析研究。
隨著輸(shu)(shu)電(dian)技(ji)術的(de)(de)(de)(de)發展(zhan)，多(duo)分(fen)裂大(da)(da)(da)截(jie)面導線(xian)(xian)(xian)在架空輸(shu)(shu)電(dian)線(xian)(xian)(xian)路中得到廣(guang)泛應用。大(da)(da)(da)截(jie)面導線(xian)(xian)(xian)分(fen)次(ci)展(zhan)放(fang)作為一種可有(you)效解決(jue)裝備制(zhi)約、維持現(xian)階段施工(gong)(gong)成本不變(bian)的(de)(de)(de)(de)放(fang)線(xian)(xian)(xian)施工(gong)(gong)方法，逐(zhu)漸為業內普遍接受，具有(you)良好(hao)的(de)(de)(de)(de)推廣(guang)價值。當(dang)前，我國特(te)高(gao)壓輸(shu)(shu)電(dian)技(ji)術發展(zhan)迅(xun)猛，在不同領域均取得突破(po)，設(she)計、施工(gong)(gong)及材料(liao)加工(gong)(gong)制(zhi)造等能力大(da)(da)(da)幅提升(sheng)，很多(duo)特(te)高(gao)壓線(xian)(xian)(xian)路設(she)備、材料(liao)已國產化。研究(jiu)適用的(de)(de)(de)(de)大(da)(da)(da)截(jie)面導線(xian)(xian)(xian)制(zhi)造技(ji)術，以及恰當(dang)可行的(de)(de)(de)(de)分(fen)次(ci)展(zhan)放(fang)架線(xian)(xian)(xian)施工(gong)(gong)方法，實現(xian)大(da)(da)(da)截(jie)面導線(xian)(xian)(xian)分(fen)次(ci)展(zhan)放(fang)，將對特(te)高(gao)壓輸(shu)(shu)電(dian)線(xian)(xian)(xian)路等相關(guan)施工(gong)(gong)起(qi)到積極推動作用。
據悉，該(gai)項目將研(yan)究在分次展放(fang)情(qing)況(kuang)下(xia)，消除(chu)導(dao)線(xian)(xian)蠕變對架線(xian)(xian)弧垂的(de)影響的(de)技(ji)術(shu)(shu)(shu)措施，提出適合分次展放(fang)的(de)導(dao)線(xian)(xian)制(zhi)造技(ji)術(shu)(shu)(shu)條(tiao)件和多(duo)分裂大截面導(dao)線(xian)(xian)分次展放(fang)施工(gong)工(gong)藝導(dao)則，為大截面導(dao)線(xian)(xian)應用(yong)提供技(ji)術(shu)(shu)(shu)可靠、先進適用(yong)的(de)制(zhi)造和施工(gong)工(gong)藝標準，為分次展放(fang)應用(yong)奠定技(ji)術(shu)(shu)(shu)基(ji)礎。
