8月18日，上海世博會(hui)國(guo)家(jia)電(dian)(dian)(dian)網企業館地下(xia)110千伏蒙自變(bian)電(dian)(dian)(dian)站配(pei)電(dian)(dian)(dian)裝置室開(kai)關(guan)柜(ju)按計劃時間節(jie)點全部安裝就位，為(wei)后續(xu)絕緣母線連接和設(she)備調試工作順利啟動奠定了(le)基礎。蒙自站采用的(de)新(xin)型(xing)開(kai)關(guan)柜(ju)具有絕緣性能好(hao)、體(ti)積小(xiao)、環保性能好(hao)的(de)優點，集(ji)中體(ti)現了(le)國(guo)家(jia)電(dian)(dian)(dian)網變(bian)電(dian)(dian)(dian)站設(she)計“兩型(xing)三新(xin)”的(de)發(fa)展方向。
國家電(dian)(dian)網企(qi)業(ye)館110千伏蒙自站電(dian)(dian)氣(qi)設備(bei)主要包(bao)括3臺容量(liang)為(wei)40兆伏安的(de)(de)主變(bian)壓器和(he)(he)(he)59臺開(kai)(kai)(kai)關(guan)(guan)(guan)柜，還(huan)包(bao)括低(di)壓饋(kui)線(xian)柜、直流屏、消(xiao)防綜合控制屏、消(xiao)防應急電(dian)(dian)源、無功補償裝置、地源熱泵系統等安裝工作。18日安裝就位的(de)(de)配電(dian)(dian)裝置采用(yong)C-GIS開(kai)(kai)(kai)關(guan)(guan)(guan)柜，是變(bian)電(dian)(dian)站連(lian)接主變(bian)和(he)(he)(he)出線(xian)的(de)(de)“神(shen)經中樞”。開(kai)(kai)(kai)關(guan)(guan)(guan)柜采用(yong)真空開(kai)(kai)(kai)關(guan)(guan)(guan)和(he)(he)(he)六氟化(hua)硫氣(qi)體絕(jue)緣(yuan)(yuan)，較(jiao)以往開(kai)(kai)(kai)關(guan)(guan)(guan)柜采用(yong)空氣(qi)絕(jue)緣(yuan)(yuan)具有(you)更安全(quan)、絕(jue)緣(yuan)(yuan)性能好、體積(ji)小等優點(dian)。其中主變(bian)開(kai)(kai)(kai)關(guan)(guan)(guan)柜、分段開(kai)(kai)(kai)關(guan)(guan)(guan)柜和(he)(he)(he)隔離(li)開(kai)(kai)(kai)關(guan)(guan)(guan)柜每臺底(di)面(mian)為(wei)0.6×1.35平方米，其他開(kai)(kai)(kai)關(guan)(guan)(guan)柜底(di)面(mian)為(wei)0.8×1.35平方米，較(jiao)普通開(kai)(kai)(kai)關(guan)(guan)(guan)柜節(jie)約占地面(mian)積(ji)1/3。另外，開(kai)(kai)(kai)關(guan)(guan)(guan)柜采用(yong)光(guang)纖代替電(dian)(dian)纜傳(chuan)輸繼保信號(hao)，有(you)效降低(di)了開(kai)(kai)(kai)關(guan)(guan)(guan)柜的(de)(de)二氧化(hua)碳(tan)排放(fang)和(he)(he)(he)功率損耗。
根據施工(gong)(gong)計(ji)劃(hua)(hua)安(an)排(pai)，國家電(dian)(dian)網(wang)企(qi)業館地下變電(dian)(dian)站全(quan)部電(dian)(dian)氣設(she)備安(an)裝(zhuang)工(gong)(gong)程(cheng)將(jiang)于(yu)10月25日結(jie)束，12月25日送電(dian)(dian)。國家電(dian)(dian)網(wang)企(qi)業館工(gong)(gong)程(cheng)總承包單位上海久隆電(dian)(dian)力(li)集團已根據現場各相關專(zhuan)業實(shi)際進(jin)度(du)對電(dian)(dian)氣安(an)裝(zhuang)計(ji)劃(hua)(hua)進(jin)行進(jin)一步補充和更新，力(li)求做到(dao)精(jing)細組織、科學管(guan)理，盡最大努力(li)克服工(gong)(gong)期(qi)緊(jin)、任(ren)務重、交叉作業多(duo)等實(shi)際困難(nan)，確(que)保電(dian)(dian)氣設(she)備安(an)裝(zhuang)工(gong)(gong)程(cheng)如期(qi)完工(gong)(gong)。
