ABB低壓開關柜MNS2.0 采用標準化的、成系列的模塊設計
MNS2.0是在(zai)ABB公(gong)司(si)MNS系(xi)列(lie)低壓(ya)開關柜技術的(de)(de)基礎上,經過得潤電氣公(gong)司(si)的(de)(de)綜合改進而開發的(de)(de)一款(kuan)產品。它采用了(le)標準化的(de)(de)、成(cheng)系(xi)列(lie)的(de)(de)模(mo)塊(kuai)設計,使得產品更加(jia)靈(ling)活、易于擴展和維護(hu)。同時,抽屜具(ju)有(you)可靠的(de)(de)機械(xie)聯(lian)鎖裝置,有(you)效防止了(le)開關在(zai)通電狀(zhuang)態下帶負荷拉閘(zha),大大提高了(le)使用的(de)(de)安全性(xing)。
ABB低壓開(kai)關柜MNS2.0適用于(yu)交流(liu)50(60)HZ、額定絕緣電(dian)(dian)(dian)(dian)(dian)壓和工作電(dian)(dian)(dian)(dian)(dian)壓為380(400)V、660v、額定電(dian)(dian)(dian)(dian)(dian)流(liu)6300A及(ji)(ji)以下(xia)三相五線制的電(dian)(dian)(dian)(dian)(dian)力供電(dian)(dian)(dian)(dian)(dian)系統。無論是(shi)發(fa)電(dian)(dian)(dian)(dian)(dian)廠、變電(dian)(dian)(dian)(dian)(dian)所(suo),還是(shi)工礦企業(ye)、大樓賓(bin)館(guan),甚(shen)至是(shi)機(ji)場、碼頭(tou)以及(ji)(ji)廣(guang)播電(dian)(dian)(dian)(dian)(dian)視(shi)等(deng)通信中心(xin),MNS2.0都能(neng)(neng)作為發(fa)電(dian)(dian)(dian)(dian)(dian)、輸配(pei)電(dian)(dian)(dian)(dian)(dian)、電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)轉換及(ji)(ji)對電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)消耗設備的控制核心(xin),并通過電(dian)(dian)(dian)(dian)(dian)容補償(chang)(chang)對其主母線進行(xing)無功補償(chang)(chang),實現了(le)電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)的高效利用。
在(zai)使(shi)用條件(jian)方面(mian),ABB低壓開關柜MNS2.0要求周圍空氣溫度(du)(du)不(bu)(bu)高(gao)于(yu)(yu)+40℃,不(bu)(bu)低于(yu)(yu)-5℃,且24小時內的(de)平均溫度(du)(du)不(bu)(bu)高(gao)于(yu)(yu)+35℃。同時,對(dui)(dui)于(yu)(yu)相對(dui)(dui)濕度(du)(du)的(de)要求也較為嚴格(ge),在(zai)最高(gao)溫度(du)(du)為+40℃時相對(dui)(dui)濕度(du)(du)不(bu)(bu)超過(guo)50%,在(zai)較低溫度(du)(du)時允(yun)許有較大的(de)相對(dui)(dui)濕度(du)(du),但應避免產生凝露(lu)。此外,該開關柜還應安裝(zhuang)在(zai)無劇烈震動和沖擊(ji),以(yi)及不(bu)(bu)使(shi)電器元(yuan)件(jian)受(shou)到腐蝕的(de)場所,以(yi)確保其穩定(ding)運行。
