　　8月18日，上(shang)海世博會國家電(dian)(dian)(dian)網(wang)企業館地下110千伏(fu)蒙自(zi)變(bian)電(dian)(dian)(dian)站(zhan)配電(dian)(dian)(dian)裝(zhuang)置(zhi)室開關柜按計劃時間節點全部安裝(zhuang)就位，為后續絕緣(yuan)母線連接和設(she)(she)備調試工作順利(li)啟動奠定了基礎。蒙自(zi)站(zhan)采用(yong)的新型開關柜具有(you)絕緣(yuan)性能好(hao)、體積小、環保性能好(hao)的優(you)點，集中體現了國家電(dian)(dian)(dian)網(wang)變(bian)電(dian)(dian)(dian)站(zhan)設(she)(she)計“兩型三(san)新”的發展方向。

　　國家電(dian)網企業館110千伏(fu)蒙自站(zhan)電(dian)氣(qi)設備主(zhu)要包括(kuo)3臺(tai)(tai)容(rong)量為40兆伏(fu)安(an)的(de)主(zhu)變(bian)(bian)壓(ya)器和(he)59臺(tai)(tai)開關(guan)(guan)(guan)柜(ju)，還包括(kuo)低(di)壓(ya)饋線(xian)柜(ju)、直流(liu)屏(ping)、消防綜(zong)合控(kong)制屏(ping)、消防應急電(dian)源、無功補償裝(zhuang)置、地(di)源熱(re)泵(beng)系統(tong)等(deng)安(an)裝(zhuang)工作。18日安(an)裝(zhuang)就(jiu)位(wei)的(de)配電(dian)裝(zhuang)置采用(yong)C-GIS開關(guan)(guan)(guan)柜(ju)，是變(bian)(bian)電(dian)站(zhan)連接主(zhu)變(bian)(bian)和(he)出線(xian)的(de)“神經(jing)中樞(shu)”。開關(guan)(guan)(guan)柜(ju)采用(yong)真空開關(guan)(guan)(guan)和(he)六氟化硫氣(qi)體絕(jue)(jue)緣，較以往開關(guan)(guan)(guan)柜(ju)采用(yong)空氣(qi)絕(jue)(jue)緣具有更安(an)全、絕(jue)(jue)緣性能好(hao)、體積小等(deng)優點。其中主(zhu)變(bian)(bian)開關(guan)(guan)(guan)柜(ju)、分段開關(guan)(guan)(guan)柜(ju)和(he)隔離(li)開關(guan)(guan)(guan)柜(ju)每臺(tai)(tai)底面為0.6×1.35平(ping)方米，其他開關(guan)(guan)(guan)柜(ju)底面為0.8×1.35平(ping)方米，較普通開關(guan)(guan)(guan)柜(ju)節約占地(di)面積1/3。另外，開關(guan)(guan)(guan)柜(ju)采用(yong)光纖代替(ti)電(dian)纜傳輸繼保信號，有效(xiao)降(jiang)低(di)了開關(guan)(guan)(guan)柜(ju)的(de)二氧化碳排放和(he)功率損耗。

　　根據(ju)施(shi)工計劃安排(pai)，國家(jia)(jia)電(dian)(dian)(dian)(dian)網企業(ye)館(guan)地下變電(dian)(dian)(dian)(dian)站全部電(dian)(dian)(dian)(dian)氣(qi)(qi)設(she)備安裝(zhuang)工程將于10月(yue)25日結(jie)束，12月(yue)25日送電(dian)(dian)(dian)(dian)。國家(jia)(jia)電(dian)(dian)(dian)(dian)網企業(ye)館(guan)工程總承(cheng)包單位上海久隆(long)電(dian)(dian)(dian)(dian)力(li)集團已根據(ju)現場各(ge)相關專業(ye)實(shi)際進(jin)度對電(dian)(dian)(dian)(dian)氣(qi)(qi)安裝(zhuang)計劃進(jin)行進(jin)一步補充和更(geng)新，力(li)求(qiu)做到(dao)精(jing)細組織、科學管理，盡最大努力(li)克(ke)服工期緊(jin)、任務重(zhong)、交叉作業(ye)多(duo)等實(shi)際困難，確保電(dian)(dian)(dian)(dian)氣(qi)(qi)設(she)備安裝(zhuang)工程如期完工。
