4月(yue)10日(ri)，國網交流(liu)工(gong)程建設(she)有限公司在特(te)高(gao)壓工(gong)程07標段N502號張力場成功進(jin)行架線施工(gong)首(shou)牽試(shi)點。這標志著我國首(shou)個特(te)高(gao)壓工(gong)程——1000千伏(fu)晉東南—南陽—荊(jing)門特(te)高(gao)壓交流(liu)試(shi)驗(yan)示范工(gong)程導線架設(she)施工(gong)正式拉(la)開帷幕(mu)。
“各就各位，開牽(qian)(qian)(qian)！”11時(shi)58分，隨(sui)著江蘇省送變電(dian)公司1000千伏晉南(nan)荊線(xian)(xian)07標(biao)段(duan)項目(mu)經理一(yi)(yi)聲令(ling)下(xia)(xia)，兩(liang)名分別操作(zuo)18噸和24噸張力機的(de)操作(zuo)人(ren)員同(tong)時(shi)轉動張力機啟動鑰匙(chi)。“轟——”機器轟鳴。在28噸牽(qian)(qian)(qian)引機的(de)強(qiang)大牽(qian)(qian)(qian)引力下(xia)(xia)，直徑(jing)為(wei)28毫米的(de)鋼絲牽(qian)(qian)(qian)引繩牽(qian)(qian)(qian)著八根LGJ-500/35鋼芯鋁絞線(xian)(xian)猛地(di)沖向藍天，向356米遠處的(de)N502號塔塔頭部位的(de)中相(xiang)九輪放(fang)(fang)線(xian)(xian)滑(hua)車疾馳(chi)而去。瞬間，鮮(xian)紅色的(de)導線(xian)(xian)一(yi)(yi)牽(qian)(qian)(qian)八走(zou)板(ban)到達(da)九輪滑(hua)車后，“嘩(hua)”的(de)一(yi)(yi)聲穿過放(fang)(fang)線(xian)(xian)滑(hua)車，繼續(xu)向前……
江蘇省送變電(dian)公司負(fu)責施工(gong)的1000千伏晉(jin)南荊線(xian)(xian)07標段(duan)，首牽架線(xian)(xian)段(duan)放線(xian)(xian)長(chang)度6.822千米(mi)，采用一牽八架線(xian)(xian)施工(gong)工(gong)藝(yi)。
目(mu)前國(guo)網交(jiao)流(liu)公(gong)司(si)(si)共在(zai)全線(xian)(xian)(xian)確定三種典型架(jia)線(xian)(xian)(xian)施工(gong)(gong)方(fang)(fang)案，即：兩(liang)組一(yi)牽(qian)四方(fang)(fang)案、一(yi)牽(qian)八(ba)方(fang)(fang)案和八(ba)牽(qian)八(ba)方(fang)(fang)案。為(wei)了統一(yi)施工(gong)(gong)操作流(liu)程(cheng)、質(zhi)量標準和施工(gong)(gong)工(gong)(gong)藝，國(guo)網交(jiao)流(liu)公(gong)司(si)(si)堅(jian)持“試點先行(xing)、樣(yang)板引(yin)路”的(de)做法，旨在(zai)驗證架(jia)線(xian)(xian)(xian)施工(gong)(gong)方(fang)(fang)案的(de)可行(xing)性和有效性，保證架(jia)線(xian)(xian)(xian)施工(gong)(gong)的(de)安(an)全和質(zhi)量。4月9日(ri)，國(guo)網交(jiao)流(liu)公(gong)司(si)(si)在(zai)承擔11標段建(jian)設的(de)河南(nan)送變電公(gong)司(si)(si)組織(zhi)召開了兩(liang)組一(yi)牽(qian)四方(fang)(fang)案架(jia)線(xian)(xian)(xian)施工(gong)(gong)首牽(qian)試點準備工(gong)(gong)作會議(yi)。
由于承擔07標段施工(gong)任務的江蘇(su)省(sheng)送變(bian)電公(gong)司的組(zu)塔工(gong)程(cheng)在全線首(shou)家通過了國(guo)家電網(wang)公(gong)司電力(li)建設工(gong)程(cheng)質量監督(du)總站檢查，具備(bei)架(jia)線試點條件，4月10日(ri)，國(guo)網(wang)交流公(gong)司確(que)定由江蘇(su)省(sheng)送變(bian)電公(gong)司在全線率先進行一(yi)牽八架(jia)線施工(gong)試點。
一牽八架線施(shi)(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝在世(shi)界特高(gao)壓工(gong)(gong)(gong)程施(shi)(shi)工(gong)(gong)(gong)中為(wei)第一次采(cai)用，施(shi)(shi)工(gong)(gong)(gong)堪(kan)稱“世(shi)界第一牽”。由(you)于一牽八架線施(shi)(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝的許多(duo)工(gong)(gong)(gong)器具(ju)及施(shi)(shi)工(gong)(gong)(gong)方法均為(wei)首次采(cai)用，此(ci)次試點施(shi)(shi)工(gong)(gong)(gong)對(dui)于驗證、完(wan)善和進一步(bu)推廣該(gai)工(gong)(gong)(gong)藝具(ju)有十分(fen)重要(yao)的意義。
