8月(yue)28日，云南(nan)電網公(gong)司昆明供電局110千伏雨龍(long)變(bian)電站全站改(gai)造(zao)項(xiang)目順利完成。這個承擔了(le)30條(tiao)10千伏線路供電任務(wu)、區域負荷密集并且服務(wu)多家高(gao)校、醫療(liao)機構及軍工企業(ye)的(de)變(bian)電站，采用(yong)了(le)與以往不同的(de)全站改(gai)造(zao)方式(shi)——“移(yi)動(dong)GIS+移(yi)動(dong)變(bian)壓器(qi)+移(yi)動(dong)開(kai)關柜(ju)”成套車載(zai)式(shi)移(yi)動(dong)變(bian)轉供電技術。

　　“110千(qian)伏雨(yu)龍變(bian)(bian)(bian)電(dian)(dian)站已持續運行(xing)27年，一二次設備普遍(bian)老(lao)化，存在(zai)不少隱患缺陷，更(geng)新改造迫在(zai)眉睫。”云南電(dian)(dian)網(wang)公司昆明供電(dian)(dian)局(ju)生(sheng)產(chan)技術部變(bian)(bian)(bian)電(dian)(dian)管理科(ke)變(bian)(bian)(bian)電(dian)(dian)檢修(xiu)專責王立告(gao)訴記者，1999年昆明世界園藝博覽會前，昆明市投運了多個變(bian)(bian)(bian)電(dian)(dian)站，目前都面臨老(lao)化問題(ti)，雨(yu)龍變(bian)(bian)(bian)電(dian)(dian)站就是其中(zhong)之一。“經過排(pai)查(cha)，像雨(yu)龍變(bian)(bian)(bian)電(dian)(dian)站這種需要全站改造的變(bian)(bian)(bian)電(dian)(dian)站有十幾個。”

　　針對變(bian)(bian)電站(zhan)集中老化問題，昆明(ming)供電局(ju)成(cheng)立專項(xiang)攻堅(jian)組(zu)，組(zu)織專家到(dao)東部超(chao)大城(cheng)市(shi)進(jin)行調研(yan)，初步(bu)決定采(cai)用“移(yi)動式(shi)變(bian)(bian)電站(zhan)”轉供電的改造(zao)方(fang)式(shi)。但是，昆明(ming)的變(bian)(bian)電站(zhan)有(you)自己獨(du)特性，別的超(chao)大城(cheng)市(shi)的改造(zao)模式(shi)不能直(zhi)接照搬。到(dao)每一個待改造(zao)變(bian)(bian)電站(zhan)進(jin)行實地(di)考察，綜合考慮轉供方(fang)式(shi)，設計車載式(shi)移(yi)動變(bian)(bian)電站(zhan)的尺寸，還(huan)要考慮2000米海拔地(di)區絕緣(yuan)間距問題……專項(xiang)攻堅(jian)組(zu)為此做了大量的前期工(gong)作。

　　“經過和廠家(jia)的反復溝通(tong)與(yu)多(duo)次協(xie)商(shang)，最終我們設計出了這款‘110千伏移(yi)(yi)動(dong)GIS+移(yi)(yi)動(dong)變壓(ya)器+移(yi)(yi)動(dong)開(kai)關柜’成套(tao)車載式(shi)移(yi)(yi)動(dong)變轉(zhuan)供電(dian)設備。”王立(li)說。

　　該(gai)(gai)設(she)備(bei)(bei)是將電(dian)(dian)(dian)(dian)(dian)氣(qi)一(yi)二次(ci)設(she)備(bei)(bei)有機整合，安裝于(yu)一(yi)至多輛半掛車(che)上的(de)(de)新型變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站，主要由高(gao)壓(ya)(ya)組合電(dian)(dian)(dian)(dian)(dian)器(qi)，主變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)，10千伏開關(guan)柜(ju)，綜合自動(dong)(dong)化系統及運輸車(che)體(ti)五大模塊組成。“我們將車(che)載(zai)(zai)式(shi)移(yi)動(dong)(dong)變(bian)(bian)(bian)(bian)轉(zhuan)供(gong)電(dian)(dian)(dian)(dian)(dian)設(she)備(bei)(bei)開到變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站內，通過轉(zhuan)供(gong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)方式(shi)，可(ke)(ke)(ke)以(yi)將待改造變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站的(de)(de)所有功能移(yi)植到這(zhe)個車(che)載(zai)(zai)式(shi)移(yi)動(dong)(dong)變(bian)(bian)(bian)(bian)轉(zhuan)供(gong)電(dian)(dian)(dian)(dian)(dian)設(she)備(bei)(bei)，就相當于(yu)它是一(yi)個備(bei)(bei)用(yong)變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站，而原本的(de)(de)變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站就可(ke)(ke)(ke)以(yi)停電(dian)(dian)(dian)(dian)(dian)改造，實現了‘零電(dian)(dian)(dian)(dian)(dian)網(wang)風險、零停電(dian)(dian)(dian)(dian)(dian)時戶’。”云南電(dian)(dian)(dian)(dian)(dian)網(wang)公司昆(kun)明供(gong)電(dian)(dian)(dian)(dian)(dian)局變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)修(xiu)試所變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)修(xiu)試四班(ban)副班(ban)長陶(tao)任介紹(shao)，該(gai)(gai)設(she)備(bei)(bei)不(bu)僅可(ke)(ke)(ke)以(yi)移(yi)動(dong)(dong)，110千伏移(yi)動(dong)(dong)GIS、移(yi)動(dong)(dong)變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)、移(yi)動(dong)(dong)開關(guan)柜(ju)都(dou)可(ke)(ke)(ke)以(yi)像積木一(yi)樣拆分，可(ke)(ke)(ke)根(gen)據不(bu)同(tong)變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站的(de)(de)特點進行組裝，適用(yong)于(yu)所有110千伏變(bian)(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站改造。

　　王立介紹(shao)，昆明供電(dian)局通過設備租賃(lin)與服務的方式(shi)，大(da)幅(fu)降(jiang)低老舊變電(dian)站改造(zao)(zao)的投(tou)資，轉(zhuan)供電(dian)成本較常規(gui)發(fa)電(dian)車模式(shi)顯著減(jian)少，為老舊變電(dian)站改造(zao)(zao)提供輕量化解決方案。“該設備具(ju)備的整體運輸(shu)、機動性(xing)強(qiang)、快(kuai)速(su)供電(dian)、組(zu)裝靈活、安裝快(kuai)捷、集成化程度(du)高的優勢，以及占地小、適(shi)應性(xing)強(qiang)，極(ji)大(da)壓縮變電(dian)站改造(zao)(zao)窗口期。”

　　目(mu)前，昆(kun)明供(gong)電(dian)(dian)局已經高效(xiao)(xiao)完成(cheng)110千伏(fu)雨龍(long)變電(dian)(dian)站的(de)(de)整(zheng)站改造，這是該設備(bei)首次(ci)使用，效(xiao)(xiao)率(lv)較傳統模式(shi)提(ti)升(sheng)50%，且實(shi)現了變電(dian)(dian)站改造期間(jian)用戶“零感知”、供(gong)電(dian)(dian)可靠性100%保(bao)障。“如果沒有這個(ge)車載(zai)式(shi)移動變轉供(gong)電(dian)(dian)設備(bei)，我(wo)(wo)們對(dui)110千伏(fu)雨龍(long)變電(dian)(dian)站的(de)(de)改造起(qi)碼得多30天。”云(yun)南電(dian)(dian)網(wang)公(gong)司昆(kun)明供(gong)電(dian)(dian)局變電(dian)(dian)運(yun)行二所胡純笑(xiao)著說，“對(dui)于我(wo)(wo)們基層班組的(de)(de)員工來說，這個(ge)創新模式(shi)減少了我(wo)(wo)們工作的(de)(de)不確定性，活好干了，效(xiao)(xiao)率(lv)還大幅提(ti)升(sheng)，電(dian)(dian)網(wang)也更安全(quan)。”

　　接下來，該(gai)(gai)設(she)(she)備(bei)將應用在位于昆(kun)明(ming)市一環邊的(de)110千伏張官營變電(dian)(dian)站(zhan)，支撐(cheng)全(quan)站(zhan)改造的(de)轉供(gong)(gong)電(dian)(dian)任務。除了(le)變電(dian)(dian)站(zhan)改造轉供(gong)(gong)電(dian)(dian)，該(gai)(gai)設(she)(she)備(bei)還可(ke)作為事故搶修的(de)備(bei)用設(she)(she)備(bei)，“我們也(ye)在探索該(gai)(gai)設(she)(she)備(bei)在臺風、地震、強降雨、雨雪(xue)冰凍等自然災害時的(de)應急搶險作用，后(hou)續還可(ke)能用于用電(dian)(dian)高峰負(fu)荷轉移、超預期規劃臨時供(gong)(gong)電(dian)(dian)，重大活(huo)動保(bao)供(gong)(gong)電(dian)(dian)等多種(zhong)作業場景。”王立提到。
