　　12月28日，在新街口(kou)外東側沿街拉開的300米(mi)警戒線內，四輛帶電(dian)作業(ye)車正在路(lu)旁作業(ye)，一輛吊車正搖(yao)動(dong)吊臂準備更換(huan)電(dian)線桿，這是北(bei)京電(dian)力(li)公(gong)(gong)司首次(ci)使用(yong)旁路(lu)作業(ye)法(fa)對(dui)不良電(dian)桿進行更換(huan)，此次(ci)旁路(lu)作業(ye)的成功操作標志著該公(gong)(gong)司具備了(le)10千伏配(pei)電(dian)線路(lu)不停電(dian)、不停負荷作業(ye)的能力(li)，達到了(le)國內先進水平。

　　此次使用(yong)(yong)旁路作(zuo)業(ye)法更(geng)(geng)換(huan)(huan)因三(san)線搭掛導致出現裂(lie)痕的(de)電(dian)(dian)(dian)(dian)桿(gan)，該10千(qian)(qian)伏配電(dian)(dian)(dian)(dian)線路共帶有(you)16個高壓用(yong)(yong)戶(hu)(hu)，如(ru)采用(yong)(yong)傳統的(de)停電(dian)(dian)(dian)(dian)作(zuo)業(ye)方(fang)式，更(geng)(geng)換(huan)(huan)該電(dian)(dian)(dian)(dian)桿(gan)需要停電(dian)(dian)(dian)(dian)至(zhi)少6小時。“使用(yong)(yong)旁路作(zuo)業(ye)法，提前將用(yong)(yong)戶(hu)(hu)的(de)用(yong)(yong)電(dian)(dian)(dian)(dian)負荷轉移到(dao)架(jia)設(she)好的(de)旁路電(dian)(dian)(dian)(dian)纜上，不(bu)用(yong)(yong)給用(yong)(yong)戶(hu)(hu)停一(yi)秒鐘(zhong)的(de)電(dian)(dian)(dian)(dian)就能進(jin)(jin)行更(geng)(geng)換(huan)(huan)。”城區供(gong)電(dian)(dian)(dian)(dian)公司(si)線路工(gong)區專(zhuan)工(gong)袁昕介(jie)紹。今年，北京電(dian)(dian)(dian)(dian)力(li)公司(si)投資700余萬引進(jin)(jin)了10千(qian)(qian)伏配電(dian)(dian)(dian)(dian)線路旁路作(zuo)業(ye)設(she)備，并邀(yao)請(qing)專(zhuan)家對(dui)相(xiang)關技(ji)術(shu)(shu)人員進(jin)(jin)行培訓。當天，北京電(dian)(dian)(dian)(dian)力(li)公司(si)帶電(dian)(dian)(dian)(dian)作(zuo)業(ye)技(ji)術(shu)(shu)中心還邀(yao)請(qing)了日本專(zhuan)家和(he)設(she)備供(gong)貨廠家技(ji)術(shu)(shu)人員到(dao)現場(chang)進(jin)(jin)行指導。

　　據統(tong)計，在(zai)所有停(ting)電(dian)(dian)中，由于檢(jian)修(xiu)配電(dian)(dian)線路(lu)而計劃停(ting)電(dian)(dian)占(zhan)停(ting)電(dian)(dian)總時(shi)間的85%，突(tu)發(fa)(fa)(fa)事(shi)故(gu)停(ting)電(dian)(dian)占(zhan)15%，傳統(tong)的配網(wang)帶(dai)電(dian)(dian)作業一般是在(zai)不帶(dai)負荷的情(qing)況(kuang)下進(jin)行(xing)(xing)(xing)，不能完(wan)全保證不停(ting)任(ren)何配網(wang)的負荷，較復(fu)雜(za)的作業還需(xu)(xu)要停(ting)電(dian)(dian)進(jin)行(xing)(xing)(xing)。而旁路(lu)作業法(fa)(fa)則(ze)是在(zai)某段(duan)線路(lu)出(chu)現(xian)突(tu)發(fa)(fa)(fa)故(gu)障進(jin)行(xing)(xing)(xing)搶修(xiu)或(huo)需(xu)(xu)要停(ting)電(dian)(dian)檢(jian)修(xiu)時(shi)，使用(yong)旁路(lu)開關、電(dian)(dian)纜和旁通線路(lu)等(deng)(deng)設(she)備，將用(yong)戶(hu)的用(yong)電(dian)(dian)負荷轉移到這些設(she)備上(shang)，或(huo)使用(yong)發(fa)(fa)(fa)電(dian)(dian)車(che)進(jin)行(xing)(xing)(xing)臨時(shi)供(gong)電(dian)(dian)，實現(xian)用(yong)戶(hu)不停(ting)電(dian)(dian)、不停(ting)負荷進(jin)行(xing)(xing)(xing)作業。比(bi)如有突(tu)發(fa)(fa)(fa)性斷(duan)桿、斷(duan)線等(deng)(deng)較大(da)事(shi)故(gu)發(fa)(fa)(fa)生時(shi)，運用(yong)旁路(lu)作業法(fa)(fa)可以迅速(su)臨時(shi)恢(hui)復(fu)供(gong)電(dian)(dian)，大(da)大(da)減少停(ting)電(dian)(dian)時(shi)間，而且恢(hui)復(fu)正常供(gong)電(dian)(dian)時(shi)不用(yong)再次(ci)停(ting)電(dian)(dian)。

　　配(pei)電(dian)(dian)(dian)(dian)線(xian)路(lu)不停(ting)電(dian)(dian)(dian)(dian)作(zuo)(zuo)(zuo)業(ye)(ye)的(de)(de)成功實(shi)現，使北(bei)京(jing)電(dian)(dian)(dian)(dian)力公司在(zai)掌握(wo)了絕(jue)緣(yuan)手套作(zuo)(zuo)(zuo)業(ye)(ye)法、絕(jue)緣(yuan)桿(gan)作(zuo)(zuo)(zuo)業(ye)(ye)法等(deng)常規帶電(dian)(dian)(dian)(dian)作(zuo)(zuo)(zuo)業(ye)(ye)方(fang)法的(de)(de)同時(shi)，具備了實(shi)施旁路(lu)作(zuo)(zuo)(zuo)業(ye)(ye)和臨(lin)時(shi)發電(dian)(dian)(dian)(dian)車送電(dian)(dian)(dian)(dian)作(zuo)(zuo)(zuo)業(ye)(ye)等(deng)先進的(de)(de)配(pei)電(dian)(dian)(dian)(dian)線(xian)路(lu)不停(ting)電(dian)(dian)(dian)(dian)作(zuo)(zuo)(zuo)業(ye)(ye)能力，達到了國內先進水平。自此(ci)，廣泛推廣此(ci)項技(ji)術后，將大(da)大(da)減少甚至避免10千伏配(pei)電(dian)(dian)(dian)(dian)線(xian)路(lu)的(de)(de)計劃停(ting)電(dian)(dian)(dian)(dian)時(shi)間，提高配(pei)網的(de)(de)供電(dian)(dian)(dian)(dian)可靠性。

　　根據北京電力公(gong)司帶(dai)(dai)電作(zuo)業(ye)的三年(nian)(nian)發展目標，目前(qian)，已經實(shi)現了城四區(qu)(qu)(qu)配(pei)電網不(bu)停電作(zuo)業(ye)，明(ming)年(nian)(nian)組(zu)建帶(dai)(dai)電作(zuo)業(ye)專業(ye)公(gong)司后，年(nian)(nian)底達到城近郊和(he)遠郊區(qu)(qu)(qu)縣城鎮(zhen)地(di)區(qu)(qu)(qu)10千(qian)伏(fu)架(jia)空線路不(bu)停電作(zuo)業(ye)的目標。最(zui)終在2009年(nian)(nian)底，實(shi)現北京平原(yuan)地(di)區(qu)(qu)(qu)所有(you)配(pei)網10千(qian)伏(fu)架(jia)空線路實(shi)現不(bu)停電作(zuo)業(ye)。
