　　12月(yue)28日，在(zai)新(xin)街口外東側沿街拉(la)開的300米警戒線內(nei)(nei)，四輛帶電(dian)作業車(che)正在(zai)路旁(pang)(pang)作業，一輛吊(diao)車(che)正搖(yao)動吊(diao)臂準備更(geng)換電(dian)線桿，這是北(bei)京(jing)電(dian)力(li)公司(si)首(shou)次(ci)使用旁(pang)(pang)路作業法(fa)對不(bu)(bu)(bu)良電(dian)桿進行更(geng)換，此次(ci)旁(pang)(pang)路作業的成功操(cao)作標志(zhi)著該公司(si)具備了(le)10千伏配電(dian)線路不(bu)(bu)(bu)停電(dian)、不(bu)(bu)(bu)停負荷(he)作業的能(neng)力(li)，達到了(le)國內(nei)(nei)先(xian)進水平。

　　此次使用(yong)旁路(lu)(lu)作業(ye)法更換因三線搭掛導致出現裂痕(hen)的(de)(de)電(dian)(dian)(dian)桿，該(gai)10千(qian)伏配電(dian)(dian)(dian)線路(lu)(lu)共帶有16個高壓用(yong)戶，如采(cai)用(yong)傳統的(de)(de)停(ting)電(dian)(dian)(dian)作業(ye)方式，更換該(gai)電(dian)(dian)(dian)桿需要停(ting)電(dian)(dian)(dian)至(zhi)少(shao)6小(xiao)時。“使用(yong)旁路(lu)(lu)作業(ye)法，提前將(jiang)用(yong)戶的(de)(de)用(yong)電(dian)(dian)(dian)負荷轉移(yi)到架設好的(de)(de)旁路(lu)(lu)電(dian)(dian)(dian)纜上，不用(yong)給用(yong)戶停(ting)一(yi)秒鐘的(de)(de)電(dian)(dian)(dian)就能進行更換。”城區供電(dian)(dian)(dian)公(gong)司(si)(si)線路(lu)(lu)工區專(zhuan)(zhuan)工袁昕介紹。今年，北京電(dian)(dian)(dian)力(li)公(gong)司(si)(si)投資700余萬(wan)引進了10千(qian)伏配電(dian)(dian)(dian)線路(lu)(lu)旁路(lu)(lu)作業(ye)設備，并(bing)邀(yao)請專(zhuan)(zhuan)家對相關技(ji)術(shu)人(ren)員(yuan)進行培訓(xun)。當天，北京電(dian)(dian)(dian)力(li)公(gong)司(si)(si)帶電(dian)(dian)(dian)作業(ye)技(ji)術(shu)中心還邀(yao)請了日本專(zhuan)(zhuan)家和(he)設備供貨(huo)廠家技(ji)術(shu)人(ren)員(yuan)到現場(chang)進行指導。

　　據(ju)統(tong)計，在所有停(ting)(ting)(ting)電(dian)(dian)(dian)(dian)中，由于檢修(xiu)配(pei)電(dian)(dian)(dian)(dian)線(xian)路(lu)(lu)(lu)而(er)計劃停(ting)(ting)(ting)電(dian)(dian)(dian)(dian)占(zhan)(zhan)停(ting)(ting)(ting)電(dian)(dian)(dian)(dian)總(zong)時(shi)間的(de)85%，突發事(shi)故停(ting)(ting)(ting)電(dian)(dian)(dian)(dian)占(zhan)(zhan)15%，傳統(tong)的(de)配(pei)網帶電(dian)(dian)(dian)(dian)作(zuo)(zuo)業一般是(shi)在不(bu)帶負(fu)荷(he)(he)(he)的(de)情況下進行(xing)(xing)，不(bu)能完全保證不(bu)停(ting)(ting)(ting)任何配(pei)網的(de)負(fu)荷(he)(he)(he)，較復雜的(de)作(zuo)(zuo)業還需(xu)要停(ting)(ting)(ting)電(dian)(dian)(dian)(dian)進行(xing)(xing)。而(er)旁(pang)路(lu)(lu)(lu)作(zuo)(zuo)業法則是(shi)在某段線(xian)路(lu)(lu)(lu)出現突發故障進行(xing)(xing)搶修(xiu)或(huo)需(xu)要停(ting)(ting)(ting)電(dian)(dian)(dian)(dian)檢修(xiu)時(shi)，使用(yong)(yong)(yong)(yong)旁(pang)路(lu)(lu)(lu)開(kai)關、電(dian)(dian)(dian)(dian)纜和(he)旁(pang)通(tong)線(xian)路(lu)(lu)(lu)等設備，將用(yong)(yong)(yong)(yong)戶(hu)的(de)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)負(fu)荷(he)(he)(he)轉移到這些(xie)設備上，或(huo)使用(yong)(yong)(yong)(yong)發電(dian)(dian)(dian)(dian)車進行(xing)(xing)臨(lin)時(shi)供電(dian)(dian)(dian)(dian)，實(shi)現用(yong)(yong)(yong)(yong)戶(hu)不(bu)停(ting)(ting)(ting)電(dian)(dian)(dian)(dian)、不(bu)停(ting)(ting)(ting)負(fu)荷(he)(he)(he)進行(xing)(xing)作(zuo)(zuo)業。比如有突發性斷桿、斷線(xian)等較大(da)事(shi)故發生時(shi)，運用(yong)(yong)(yong)(yong)旁(pang)路(lu)(lu)(lu)作(zuo)(zuo)業法可以(yi)迅速臨(lin)時(shi)恢復供電(dian)(dian)(dian)(dian)，大(da)大(da)減少(shao)停(ting)(ting)(ting)電(dian)(dian)(dian)(dian)時(shi)間，而(er)且(qie)恢復正常供電(dian)(dian)(dian)(dian)時(shi)不(bu)用(yong)(yong)(yong)(yong)再次停(ting)(ting)(ting)電(dian)(dian)(dian)(dian)。

　　配電(dian)線路不(bu)停(ting)電(dian)作業的成(cheng)功實(shi)現(xian)，使(shi)北京電(dian)力(li)公司(si)在掌握了(le)絕緣(yuan)手套作業法、絕緣(yuan)桿作業法等常規(gui)帶電(dian)作業方法的同時，具備了(le)實(shi)施旁路作業和(he)臨(lin)時發電(dian)車送電(dian)作業等先進的配電(dian)線路不(bu)停(ting)電(dian)作業能(neng)力(li)，達(da)到了(le)國內先進水平(ping)。自此(ci)，廣泛推廣此(ci)項技術后，將大大減少甚(shen)至(zhi)避免10千伏配電(dian)線路的計(ji)劃停(ting)電(dian)時間，提高(gao)配網的供電(dian)可靠性。

　　根(gen)據北(bei)京電(dian)(dian)力公司(si)帶(dai)電(dian)(dian)作(zuo)業的三年(nian)(nian)發展目(mu)(mu)標(biao)(biao)，目(mu)(mu)前，已經實(shi)現(xian)了城四區配電(dian)(dian)網不停電(dian)(dian)作(zuo)業，明年(nian)(nian)組建帶(dai)電(dian)(dian)作(zuo)業專業公司(si)后，年(nian)(nian)底達到城近郊和遠郊區縣(xian)城鎮(zhen)地(di)區10千(qian)(qian)伏(fu)架(jia)空線路(lu)不停電(dian)(dian)作(zuo)業的目(mu)(mu)標(biao)(biao)。最終在2009年(nian)(nian)底，實(shi)現(xian)北(bei)京平原地(di)區所有(you)配網10千(qian)(qian)伏(fu)架(jia)空線路(lu)實(shi)現(xian)不停電(dian)(dian)作(zuo)業。
