　　12月28日，在新街(jie)口外(wai)東側沿街(jie)拉(la)開的300米警戒線(xian)內，四輛帶電(dian)(dian)作業(ye)車(che)正在路(lu)旁(pang)作業(ye)，一輛吊車(che)正搖動吊臂準備(bei)更(geng)換(huan)(huan)電(dian)(dian)線(xian)桿，這是(shi)北京(jing)電(dian)(dian)力(li)公司首(shou)次使用旁(pang)路(lu)作業(ye)法對不良電(dian)(dian)桿進(jin)行更(geng)換(huan)(huan)，此次旁(pang)路(lu)作業(ye)的成功操(cao)作標志(zhi)著(zhu)該公司具(ju)備(bei)了10千(qian)伏配電(dian)(dian)線(xian)路(lu)不停電(dian)(dian)、不停負荷(he)作業(ye)的能(neng)力(li)，達到了國內先進(jin)水(shui)平(ping)。

　　此(ci)次(ci)使用(yong)(yong)(yong)旁(pang)路作業(ye)法更(geng)換(huan)因三線(xian)搭掛導(dao)致(zhi)出現裂痕的電(dian)(dian)(dian)(dian)桿(gan)，該10千(qian)伏(fu)配電(dian)(dian)(dian)(dian)線(xian)路共帶有(you)16個高(gao)壓(ya)用(yong)(yong)(yong)戶(hu)(hu)，如采用(yong)(yong)(yong)傳統的停電(dian)(dian)(dian)(dian)作業(ye)方(fang)式，更(geng)換(huan)該電(dian)(dian)(dian)(dian)桿(gan)需要停電(dian)(dian)(dian)(dian)至少6小時。“使用(yong)(yong)(yong)旁(pang)路作業(ye)法，提前將用(yong)(yong)(yong)戶(hu)(hu)的用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)負(fu)荷轉移(yi)到架設好(hao)的旁(pang)路電(dian)(dian)(dian)(dian)纜上，不用(yong)(yong)(yong)給用(yong)(yong)(yong)戶(hu)(hu)停一秒鐘的電(dian)(dian)(dian)(dian)就能進(jin)行(xing)(xing)更(geng)換(huan)。”城區(qu)供(gong)電(dian)(dian)(dian)(dian)公(gong)(gong)司線(xian)路工區(qu)專(zhuan)工袁昕介紹(shao)。今年，北(bei)京電(dian)(dian)(dian)(dian)力(li)公(gong)(gong)司投資700余萬引進(jin)了10千(qian)伏(fu)配電(dian)(dian)(dian)(dian)線(xian)路旁(pang)路作業(ye)設備，并邀請專(zhuan)家對相關技(ji)術(shu)(shu)人(ren)員(yuan)進(jin)行(xing)(xing)培訓。當天，北(bei)京電(dian)(dian)(dian)(dian)力(li)公(gong)(gong)司帶電(dian)(dian)(dian)(dian)作業(ye)技(ji)術(shu)(shu)中心還(huan)邀請了日本(ben)專(zhuan)家和(he)設備供(gong)貨廠家技(ji)術(shu)(shu)人(ren)員(yuan)到現場進(jin)行(xing)(xing)指導(dao)。

　　據(ju)統(tong)計，在(zai)所有停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)中，由于檢修配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)路而計劃(hua)停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)占停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)總時(shi)間(jian)的(de)85%，突(tu)發(fa)(fa)(fa)事故停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)占15%，傳統(tong)的(de)配(pei)網帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)作(zuo)業(ye)(ye)一般是在(zai)不(bu)帶負荷(he)的(de)情況下進(jin)行(xing)(xing)，不(bu)能完全保(bao)證不(bu)停(ting)(ting)任何配(pei)網的(de)負荷(he)，較復雜的(de)作(zuo)業(ye)(ye)還需(xu)要停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)進(jin)行(xing)(xing)。而旁路作(zuo)業(ye)(ye)法則(ze)是在(zai)某段線(xian)(xian)(xian)路出現突(tu)發(fa)(fa)(fa)故障進(jin)行(xing)(xing)搶(qiang)修或(huo)需(xu)要停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)檢修時(shi)，使(shi)(shi)用(yong)旁路開關、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜和(he)旁通線(xian)(xian)(xian)路等設(she)備，將用(yong)戶的(de)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)負荷(he)轉移到這(zhe)些設(she)備上，或(huo)使(shi)(shi)用(yong)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)車(che)進(jin)行(xing)(xing)臨時(shi)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，實(shi)現用(yong)戶不(bu)停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)、不(bu)停(ting)(ting)負荷(he)進(jin)行(xing)(xing)作(zuo)業(ye)(ye)。比如有突(tu)發(fa)(fa)(fa)性斷(duan)桿、斷(duan)線(xian)(xian)(xian)等較大事故發(fa)(fa)(fa)生時(shi)，運用(yong)旁路作(zuo)業(ye)(ye)法可以迅速臨時(shi)恢(hui)復供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，大大減少停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)間(jian)，而且恢(hui)復正常供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)不(bu)用(yong)再次停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

　　配(pei)電(dian)(dian)(dian)(dian)(dian)線路不停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)作(zuo)(zuo)業(ye)(ye)的成功實(shi)現，使北京電(dian)(dian)(dian)(dian)(dian)力(li)公司(si)在(zai)掌握了絕緣手套作(zuo)(zuo)業(ye)(ye)法、絕緣桿作(zuo)(zuo)業(ye)(ye)法等常規帶電(dian)(dian)(dian)(dian)(dian)作(zuo)(zuo)業(ye)(ye)方(fang)法的同時(shi)，具(ju)備了實(shi)施旁(pang)路作(zuo)(zuo)業(ye)(ye)和(he)臨時(shi)發(fa)電(dian)(dian)(dian)(dian)(dian)車送電(dian)(dian)(dian)(dian)(dian)作(zuo)(zuo)業(ye)(ye)等先進的配(pei)電(dian)(dian)(dian)(dian)(dian)線路不停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)作(zuo)(zuo)業(ye)(ye)能(neng)力(li)，達到了國內先進水平。自此(ci)，廣泛推(tui)廣此(ci)項技術后，將大(da)大(da)減少甚至避免(mian)10千(qian)伏(fu)配(pei)電(dian)(dian)(dian)(dian)(dian)線路的計(ji)劃停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)時(shi)間，提高(gao)配(pei)網的供電(dian)(dian)(dian)(dian)(dian)可靠性。

　　根據北京電(dian)力公司帶電(dian)作(zuo)(zuo)業的三(san)年(nian)發展目(mu)標(biao)，目(mu)前，已(yi)經實現了城(cheng)四區配電(dian)網(wang)不停電(dian)作(zuo)(zuo)業，明年(nian)組建帶電(dian)作(zuo)(zuo)業專(zhuan)業公司后，年(nian)底達(da)到城(cheng)近郊(jiao)和遠郊(jiao)區縣(xian)城(cheng)鎮地區10千伏架空線路(lu)不停電(dian)作(zuo)(zuo)業的目(mu)標(biao)。最終在(zai)2009年(nian)底，實現北京平原地區所(suo)有配網(wang)10千伏架空線路(lu)實現不停電(dian)作(zuo)(zuo)業。
