集裝箱式變電站是(shi)(shi)一種可以(yi)自由組合(he)的(de)(de)配(pei)電設備，具有結構堅(jian)固、功能齊全、整體美觀、安(an)裝方(fang)便(bian)、操作方(fang)便(bian)、占地面積小、耐久性強、耐腐蝕(shi)、防(fang)雷(lei)等特點。近(jin)幾(ji)年，電氣行業內有很多不同(tong)的(de)(de)型號變(bian)電站，那么如何選擇合(he)適(shi)的(de)(de)集(ji)裝箱(xiang)(xiang)式變(bian)電站是(shi)(shi)大家(jia)關注的(de)(de)，今天就(jiu)給(gei)大家(jia)深入了解集(ji)裝箱(xiang)(xiang)式變(bian)電站的(de)(de)組成。

一、高壓室內(nei)部設備選擇(ze)

高壓室的配電設備一般采用10KV高壓開關柜，其(qi)高(gao)(gao)壓(ya)負荷開(kai)(kai)關經常(chang)(chang)(chang)用(yong)(yong)于開(kai)(kai)斷(duan)(duan)正(zheng)(zheng)常(chang)(chang)(chang)負荷電(dian)(dian)(dian)流(liu)，用(yong)(yong)戶(hu)開(kai)(kai)斷(duan)(duan)短(duan)路(lu)電(dian)(dian)(dian)流(liu)的情況非常(chang)(chang)(chang)少，通常(chang)(chang)(chang)采用(yong)(yong)高(gao)(gao)壓(ya)負荷開(kai)(kai)關加(jia)熔(rong)斷(duan)(duan)器組合電(dian)(dian)(dian)器來代替高(gao)(gao)壓(ya)斷(duan)(duan)路(lu)器，這樣可以(yi)(yi)大(da)大(da)提高(gao)(gao)設備綜合投資經濟效益。10kV箱式(shi)變(bian)電(dian)(dian)(dian)站中(zhong)，由(you)高(gao)(gao)壓(ya)負荷開(kai)(kai)關實(shi)現開(kai)(kai)斷(duan)(duan)變(bian)電(dian)(dian)(dian)站系統正(zheng)(zheng)常(chang)(chang)(chang)負荷電(dian)(dian)(dian)流(liu)，由(you)熔(rong)斷(duan)(duan)器實(shi)現開(kai)(kai)斷(duan)(duan)變(bian)電(dian)(dian)(dian)站系統的故(gu)障短(duan)路(lu)電(dian)(dian)(dian)流(liu)，確保(bao)變(bian)電(dian)(dian)(dian)站安全(quan)穩定的運行。當然除了10KV高(gao)(gao)壓(ya)柜，也可以(yi)(yi)配(pei)用(yong)(yong)10KV高(gao)(gao)壓(ya)環網(wang)柜，因負載(zai)容(rong)不大(da)，其(qi)高(gao)(gao)壓(ya)回路(lu)通常(chang)(chang)(chang)采用(yong)(yong)負荷開(kai)(kai)關或(huo)真空接觸器控(kong)制，并配(pei)有高(gao)(gao)壓(ya)熔(rong)斷(duan)(duan)器保(bao)護。可以(yi)(yi)提高(gao)(gao)供(gong)電(dian)(dian)(dian)可靠性，使用(yong)(yong)戶(hu)可以(yi)(yi)從兩(liang)個(ge)方向獲得電(dian)(dian)(dian)源。

二、變壓室(shi)內部設備(bei)選(xuan)擇

箱式(shi)(shi)(shi)變(bian)電(dian)站(zhan)變(bian)壓(ya)(ya)(ya)器(qi)(qi)通常選用(yong)干式(shi)(shi)(shi)配(pei)(pei)電(dian)變(bian)壓(ya)(ya)(ya)器(qi)(qi)。配(pei)(pei)電(dian)變(bian)壓(ya)(ya)(ya)器(qi)(qi)的(de)容(rong)(rong)量(liang)應根據(ju)電(dian)力負(fu)荷特(te)點(dian)和運行(xing)方式(shi)(shi)(shi)進行(xing)選擇，單(dan)臺配(pei)(pei)電(dian)變(bian)壓(ya)(ya)(ya)器(qi)(qi)設計容(rong)(rong)量(liang)不宜超過1250kVA，如果統(tong)計負(fu)荷容(rong)(rong)量(liang)較大時，建議選用(yong)兩臺變(bian)壓(ya)(ya)(ya)器(qi)(qi)自動切(qie)換運行(xing)方案。干式(shi)(shi)(shi)變(bian)壓(ya)(ya)(ya)器(qi)(qi)不需(xu)要檢查油位(wei)、油溫、油質、以及油壓(ya)(ya)(ya)等(deng)(deng)特(te)性參數，也稱為免維(wei)護式(shi)(shi)(shi)配(pei)(pei)電(dian)變(bian)壓(ya)(ya)(ya)器(qi)(qi)，加上其具(ju)有阻燃(ran)、防爆等(deng)(deng)優點(dian)，在箱式(shi)(shi)(shi)變(bian)電(dian)站(zhan)設計中(zhong)成為優選的(de)變(bian)壓(ya)(ya)(ya)器(qi)(qi)類型。SCB11-1600型干式(shi)(shi)(shi)電(dian)力變(bian)壓(ya)(ya)(ya)器(qi)(qi)是目前主要被廣大用(yong)戶使(shi)用(yong)的(de)一款(kuan)干式(shi)(shi)(shi)變(bian)壓(ya)(ya)(ya)器(qi)(qi)，具(ju)有低損耗、低噪聲、高耐熱等(deng)(deng)特(te)點(dian)。

三、低壓室內部設備選(xuan)擇(ze)

低(di)壓(ya)室一(yi)般(ban)選用(yong)進線(xian)(xian)(xian)(xian)柜(ju)(ju)(ju)、出線(xian)(xian)(xian)(xian)柜(ju)(ju)(ju)、電(dian)(dian)容柜(ju)(ju)(ju)、抽(chou)屜(ti)柜(ju)(ju)(ju)等(deng)低(di)壓(ya)開關(guan)柜(ju)(ju)(ju)。常(chang)(chang)用(yong)的(de)開關(guan)柜(ju)(ju)(ju)型(xing)有MNS2.0、Blokset等(deng)開關(guan)柜(ju)(ju)(ju)，而箱式變電(dian)(dian)站其(qi)(qi)內(nei)部(bu)集成程度(du)較高，一(yi)次電(dian)(dian)路(lu)(lu)較為簡單，通常(chang)(chang)只包括進線(xian)(xian)(xian)(xian)、出線(xian)(xian)(xian)(xian)補償功能，因為，為了(le)減少低(di)壓(ya)柜(ju)(ju)(ju)在(zai)箱變內(nei)部(bu)的(de)占地面積，應優化低(di)壓(ya)電(dian)(dian)器(qi)(qi)(qi)(qi)的(de)布(bu)置結構(gou)。主回(hui)(hui)路(lu)(lu)中應選用(yong)多功能萬能式斷(duan)路(lu)(lu)器(qi)(qi)(qi)(qi)，即(ji)可以(yi)手動(dong)(dong)又可電(dian)(dian)動(dong)(dong)操作的(de)自動(dong)(dong)低(di)壓(ya)饋電(dian)(dian)開關(guan)，并配有過載長延時(shi)、短路(lu)(lu)短延時(shi)、以(yi)及(ji)短路(lu)(lu)瞬間保(bao)護，以(yi)及(ji)失壓(ya)和(he)分勵(li)等(deng)多種自動(dong)(dong)脫(tuo)扣(kou)器(qi)(qi)(qi)(qi)和(he)輔助結構(gou)，構(gou)成比較完(wan)善系統的(de)綜合(he)保(bao)護系統。對于(yu)分支饋電(dian)(dian)線(xian)(xian)(xian)(xian)路(lu)(lu)而言，應選用(yong)塑(su)料外殼式斷(duan)路(lu)(lu)器(qi)(qi)(qi)(qi)，利用(yong)其(qi)(qi)自身(shen)所帶的(de)短路(lu)(lu)保(bao)護熱脫(tuo)扣(kou)裝置，有效(xiao)提高饋線(xian)(xian)(xian)(xian)回(hui)(hui)路(lu)(lu)運行安全可靠性。
