6月2日上午，500千(qian)伏(fu)靜安（世博）變電站進線青年工程(cheng)在上海浦東成山(shan)路(lu)開工。該工程(cheng)是目(mu)前世界上線路(lu)長度最(zui)長、接頭(tou)數量最(zui)多(duo)的500千(qian)伏(fu)電纜工程(cheng)，工程(cheng)計(ji)劃于(yu)2010年3月竣工。
由上(shang)(shang)海電(dian)(dian)力電(dian)(dian)纜(lan)(lan)(lan)工(gong)(gong)程(cheng)(cheng)有限公(gong)司施工(gong)(gong)的500千伏(fu)世(shi)博(bo)變(bian)(bian)進(jin)線工(gong)(gong)程(cheng)(cheng)，是為(wei)緩解上(shang)(shang)海市中心城(cheng)區(qu)供電(dian)(dian)壓力，確保2010年世(shi)博(bo)會電(dian)(dian)力供應的一項重大工(gong)(gong)程(cheng)(cheng)。工(gong)(gong)程(cheng)(cheng)自浦(pu)東(dong)三(san)林(lin)變(bian)(bian)電(dian)(dian)站至浦(pu)西靜(jing)安(an)(世(shi)博(bo))地下變(bian)(bian)電(dian)(dian)站，全線雙回500千伏(fu)電(dian)(dian)纜(lan)(lan)(lan)全部敷設(she)于(yu)新(xin)建電(dian)(dian)力隧道內，隧道經北京西路(lu)至華(hua)夏(xia)西路(lu)全長(chang)近(jin)16千米，隧道最大直徑達(da)(da)(da)5.5米，全線設(she)電(dian)(dian)纜(lan)(lan)(lan)工(gong)(gong)作(zuo)井15座，最深處(chu)位于(yu)地下29米，共有500千伏(fu)電(dian)(dian)纜(lan)(lan)(lan)中間接頭(tou)147相，GIS終端(duan)12相。工(gong)(gong)程(cheng)(cheng)電(dian)(dian)纜(lan)(lan)(lan)在(zai)隧道中采(cai)用(yong)“品”字形排列，設(she)計(ji)容(rong)量(liang)達(da)(da)(da)100萬千瓦，電(dian)(dian)纜(lan)(lan)(lan)截面(mian)達(da)(da)(da)到2500平方毫米，單盤(pan)電(dian)(dian)纜(lan)(lan)(lan)分別為(wei)640米和720米，單盤(pan)重量(liang)都超(chao)過(guo)30噸(dun)。
作為(wei)世界領(ling)先的(de)(de)大型工(gong)(gong)程(cheng)，工(gong)(gong)程(cheng)面臨敷(fu)設施工(gong)(gong)路徑(jing)長、工(gong)(gong)井深、電(dian)纜(lan)(lan)重、隧道通信困難等諸多難點(dian)。為(wei)確(que)保工(gong)(gong)程(cheng)按質(zhi)按期完成，電(dian)纜(lan)(lan)公司在敷(fu)設施工(gong)(gong)中(zhong)，采用500千伏(fu)電(dian)纜(lan)(lan)專(zhuan)用放線架，結合電(dian)動(dong)導輪和履帶(dai)式輸(shu)送(song)機變頻聯動(dong)敷(fu)設，確(que)保電(dian)纜(lan)(lan)敷(fu)設安全(quan)、可靠、高效(xiao)(xiao)。在隧道通信方(fang)面，采用隧道專(zhuan)用通信系(xi)統(tong)，大大提高了工(gong)(gong)作效(xiao)(xiao)率。在接頭(tou)施工(gong)(gong)中(zhong)，采用自主開發的(de)(de)電(dian)纜(lan)(lan)隧道接頭(tou)環境監控系(xi)統(tong)，對潔凈度、濕度、溫度進行全(quan)面監控，確(que)保超(chao)凈的(de)(de)接頭(tou)環境。
