2023年12月29日，青(qing)海750千伏(fu)昆(kun)侖山輸變(bian)電工程正式投入運行，進一步增強了青(qing)海海西(xi)地(di)區電網(wang)主網(wang)架結(jie)構(gou)、推(tui)動新能(neng)源(yuan)大規模開(kai)發(fa)利用，為青(qing)海省電力安(an)全保供和(he)打造國家清(qing)潔能(neng)源(yuan)產業高地(di)提供重要支撐。

　　750千(qian)(qian)伏(fu)昆(kun)侖山輸變(bian)電(dian)(dian)(dian)工(gong)程是青(qing)海省首批“沙戈荒(huang)”大(da)型風電(dian)(dian)(dian)光伏(fu)基地(di)的重點配(pei)套工(gong)程之一，新(xin)(xin)建750千(qian)(qian)伏(fu)昆(kun)侖山變(bian)電(dian)(dian)(dian)站(zhan)1座，新(xin)(xin)建750千(qian)(qian)伏(fu)線路2條(tiao)，與750千(qian)(qian)伏(fu)柴達木(mu)換流(liu)站(zhan)相(xiang)連;新(xin)(xin)建330千(qian)(qian)伏(fu)線路5條(tiao)，與周邊新(xin)(xin)能源匯集站(zhan)相(xiang)連，滿(man)足新(xin)(xin)能源電(dian)(dian)(dian)力的匯集和(he)送出需求。

　　工程(cheng)建設(she)期間，國網青海省(sheng)電力公(gong)司充分發揮技(ji)術、人(ren)才、管(guan)理(li)等方面(mian)優勢，組(zu)織(zhi)數千名電網建設(she)者(zhe)克服沙漠和(he)戈(ge)壁艱苦的施工條件，精(jing)益(yi)施工、高效(xiao)推動工程(cheng)建設(she)，僅用1年時間，在(zai)確(que)保(bao)安全和(he)質(zhi)量的前提(ti)下提(ti)前完(wan)成了建設(she)任務。

　　攻堅克難　戈壁上建起變電站

　　2022年11月底，750千伏(fu)昆(kun)侖山輸變(bian)電(dian)工(gong)(gong)(gong)程開工(gong)(gong)(gong)建設。12月6日(ri)，青海送變(bian)電(dian)工(gong)(gong)(gong)程有限(xian)公司土建分公司項目經(jing)理(li)、750千伏(fu)昆(kun)侖山變(bian)電(dian)站工(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)項目副經(jing)理(li)陳守璽帶領7名技(ji)術(shu)人員，趕赴格爾木(mu)市烏圖美仁光伏(fu)光熱園區內的(de)施(shi)工(gong)(gong)(gong)現(xian)場開展現(xian)場勘查工(gong)(gong)(gong)作。

　　陳守璽有著18年工程建設經(jing)驗，但烏圖美(mei)仁(ren)鄉(xiang)施(shi)工現場的艱苦條(tiao)件大(da)大(da)超出了他(ta)的預期(qi)：滿(man)目戈壁黃(huang)沙，四(si)野荒無(wu)人煙，白天(tian)狂風驟(zou)起，夜間(jian)氣溫(wen)驟(zou)降，最近的鎮子也在20千米外(wai)。

　　12月8日，兩天(tian)的勘查(cha)結束后(hou)，青海送變(bian)電公司(si)土建(jian)(jian)分公司(si)組織人(ren)員、機(ji)(ji)械、材料(liao)進場(chang)。“施工現場(chang)1.3千米直(zhi)徑范圍內的地(di)(di)面全部被沙覆(fu)蓋，兩驅車根本進不去(qu)。”回(hui)想當時(shi)的情景，陳守璽記憶猶新，“我(wo)們用(yong)裝載機(ji)(ji)前(qian)拉(la)后(hou)推，硬是把載有(you)物資的貨車拉(la)到工地(di)(di)，然(ran)后(hou)搭(da)起帳篷生火爐取(qu)暖，一邊(bian)搭(da)建(jian)(jian)項目部，一邊(bian)平整場(chang)坪(ping)。”

　　針對惡劣的冬季(ji)施(shi)工(gong)環境，陳守璽和(he)同事們下(xia)了一(yi)番功夫(fu)。為確(que)(que)保(bao)混(hun)凝土(tu)攪拌(ban)質量(liang)，施(shi)工(gong)人(ren)員把水溫加熱到60攝(she)氏度后再投入使用;基礎(chu)混(hun)凝土(tu)澆筑完成后，施(shi)工(gong)人(ren)員在基礎(chu)表(biao)面覆蓋兩層塑料薄膜、兩層棉(mian)毯(tan)保(bao)溫養護，并在現場(chang)搭設(she)暖棚，加設(she)火爐、暖風機(ji)保(bao)暖養護，確(que)(que)保(bao)混(hun)凝土(tu)成型質量(liang)。

　　2023年5月(yue)(yue)25日(ri)，昆侖(lun)山(shan)變電(dian)(dian)(dian)站第一批(pi)主(zhu)變壓器、高抗(kang)基(ji)(ji)礎(chu)具備(bei)就位(wei)條(tiao)件;6月(yue)(yue)底(di)，土建(jian)施工完成，準備(bei)進入電(dian)(dian)(dian)氣(qi)安裝(zhuang)階段(duan)，工程進度(du)遠(yuan)(yuan)遠(yuan)(yuan)超出(chu)預期。該(gai)工程基(ji)(ji)礎(chu)模板拆(chai)除后，混凝(ning)土表(biao)面幾乎能夠(gou)達到鏡(jing)面效果。昆侖(lun)山(shan)變電(dian)(dian)(dian)站全站66組構架基(ji)(ji)礎(chu)、642個(ge)復(fu)合(he)(he)式氣(qi)體絕緣(yuan)組合(he)(he)電(dian)(dian)(dian)器基(ji)(ji)礎(chu)和8956根地(di)腳螺栓，沒有一項因為(wei)質量問題影響構架吊裝(zhuang)和設(she)備(bei)安裝(zhuang)。

　　精益施工　提升設備安裝質量

　　2023年6月份，750千(qian)伏昆侖山變(bian)電(dian)站工(gong)程進入(ru)電(dian)氣(qi)安裝環(huan)節。電(dian)氣(qi)安裝技術總負責人王章海(hai)帶領數十名技術人員率先(xian)入(ru)駐，著手(shou)開展相關準備工(gong)作。

　　750千(qian)伏(fu)(fu)、330千(qian)伏(fu)(fu)氣體絕緣全封閉組合電器(GIS)安(an)裝(zhuang)工藝對環境(jing)要求極高，需要在無(wu)塵(chen)條件下開展(zhan)。烏圖美仁地(di)處荒漠戈壁，入(ru)夏后天氣炎(yan)熱，現場塵(chen)土飛揚，給(gei)GIS安(an)裝(zhuang)帶來(lai)極大挑戰。

　　為(wei)此，施工人員(yuan)在做好7級(ji)防塵(chen)的基礎上增加了(le)防塵(chen)措施：引進智能化噴淋系統，為(wei)設備安(an)裝(zhuang)(zhuang)創造(zao)條(tiao)件。在施工人員(yuan)精(jing)心作業下(xia)，GIS安(an)裝(zhuang)(zhuang)工作實現安(an)裝(zhuang)(zhuang)一次完成、耐壓(ya)試驗一次通過(guo)。

　　750千伏主變壓(ya)器箱體長約(yue)6米(mi)、寬約(yue)2米(mi)、高約(yue)4米(mi)，像一(yi)間密閉的房(fang)間。項目管理人(ren)員(yuan)(yuan)在變壓(ya)器箱體外部設置牢固的安(an)全(quan)帶掛點，并(bing)在周圍加裝(zhuang)了特殊材質(zhi)的網圍欄，保障箱體外部高空(kong)作(zuo)業(ye)安(an)全(quan)。在箱體內部，施(shi)工人(ren)員(yuan)(yuan)加裝(zhuang)大功率(lv)通風裝(zhuang)置，全(quan)程輸送干燥新鮮的空(kong)氣，并(bing)由專人(ren)監測含氧量，從而(er)保證人(ren)員(yuan)(yuan)安(an)全(quan)和安(an)裝(zhuang)質(zhi)量。

　　國(guo)網青海電力以(yi)建(jian)設(she)環(huan)境友好(hao)型工(gong)(gong)(gong)(gong)(gong)程(cheng)為目標(biao)，全面強(qiang)化工(gong)(gong)(gong)(gong)(gong)程(cheng)環(huan)保(bao)(bao)、水保(bao)(bao)工(gong)(gong)(gong)(gong)(gong)作，加強(qiang)綠色施工(gong)(gong)(gong)(gong)(gong)管(guan)理，將工(gong)(gong)(gong)(gong)(gong)程(cheng)現場打造(zao)為綠色工(gong)(gong)(gong)(gong)(gong)地。該(gai)公司限定施工(gong)(gong)(gong)(gong)(gong)機械(xie)在基礎周邊的作業范圍，并廣泛使(shi)用草(cao)墊、彩(cai)條布將機械(xie)、砂石等(deng)與地表(biao)隔(ge)離(li)，加大環(huan)保(bao)(bao)、水保(bao)(bao)現場監督力度(du)。

　　強化管控　確保工程提前完成

　　750千伏昆侖山輸變電工(gong)(gong)程工(gong)(gong)期緊、任務重(zhong)，參建隊伍眾多、人員復雜，存在多專業深度(du)交叉作業的(de)情況，工(gong)(gong)程管(guan)控(kong)難度(du)大。國網青海電力(li)結合工(gong)(gong)程實際(ji)，強(qiang)化項目部(bu)組(zu)織分(fen)工(gong)(gong)，建立以業主項目部(bu)為代表(biao)，施(shi)工(gong)(gong)、監理(li)等參建單位協同配合的(de)建設(she)管(guan)理(li)、安(an)全(quan)質量、物資供(gong)應及運輸等保(bao)障體(ti)系。該(gai)公(gong)司精(jing)心(xin)組(zu)織，周密安(an)排，層(ceng)層(ceng)分(fen)解(jie)落實責任，形成全(quan)面覆(fu)蓋(gai)、不留(liu)死角的(de)工(gong)(gong)作體(ti)系，確保(bao)了(le)工(gong)(gong)程建設(she)高效推進。

　　工(gong)程輸電線路走廊穿越沙漠、戈壁、河網，地質條件復雜，其(qi)中有(you)6基(ji)鐵塔基(ji)礎是挖(wa)孔樁基(ji)礎，需要在沙漠里先挖(wa)出直(zhi)徑1.2米(mi)(mi)、深10米(mi)(mi)多的(de)坑。受(shou)流(liu)沙影響，傳統施(shi)工(gong)方(fang)法(fa)難(nan)以實施(shi)。經驗豐富(fu)的(de)項目(mu)總工(gong)程師李松借鑒沼(zhao)澤地區施(shi)工(gong)方(fang)法(fa)，組織施(shi)工(gong)人員特制了直(zhi)徑1.2米(mi)(mi)、高1.5米(mi)(mi)的(de)鋼護(hu)筒來防止(zhi)流(liu)沙，在半(ban)個月時間內高效完(wan)成了6基(ji)挖(wa)孔樁基(ji)礎施(shi)工(gong)。

　　2023年6月(yue)(yue)(yue)8日，在750千伏(fu)昆(kun)侖山輸電(dian)(dian)(dian)線路工(gong)(gong)(gong)(gong)(gong)(gong)程鐵塔組立(li)現場，李松根(gen)據圖紙指導施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)人員開(kai)展(zhan)塔材組裝(zhuang)工(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)。施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)人員在地(di)面(mian)把一塊(kuai)塊(kuai)塔材組裝(zhuang)成片，然后(hou)通(tong)過(guo)小(xiao)型(xing)吊(diao)車(che)吊(diao)裝(zhuang)組立(li)塔腿、塔身部分，最(zui)后(hou)由大型(xing)吊(diao)車(che)吊(diao)裝(zhuang)組立(li)塔頭、橫擔部分。10月(yue)(yue)(yue)底，750千伏(fu)輸電(dian)(dian)(dian)線路全(quan)面(mian)建(jian)成。11月(yue)(yue)(yue)初，昆(kun)侖山變電(dian)(dian)(dian)站工(gong)(gong)(gong)(gong)(gong)(gong)程全(quan)面(mian)建(jian)成。11月(yue)(yue)(yue)10日，昆(kun)侖山輸變電(dian)(dian)(dian)工(gong)(gong)(gong)(gong)(gong)(gong)程驗收(shou)及缺(que)陷(xian)消除工(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)啟動，國網(wang)青海電(dian)(dian)(dian)力(li)統籌協(xie)調運維、施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)、設計及物資供應(ying)等(deng)單位聯合開(kai)展(zhan)工(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)，為工(gong)(gong)(gong)(gong)(gong)(gong)程順(shun)利投(tou)運打好基礎(chu)。（來源：國家(jia)電(dian)(dian)(dian)網(wang)報(bao)）
