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ABB公司MNS系列(lie)(lie)低壓開(kai)(kai)(kai)關柜技術的基(ji)礎上(shang),經過得(de)潤(run)電(dian)氣公司的綜合改進而(er)開(kai)(kai)(kai)發(fa)的一(yi)款產品。它(ta)采(cai)用(yong)了標準化的、成(cheng)系列(lie)(lie)的模塊設計,使得(de)產品更加(jia)靈活、易于擴展和維(wei)護(hu)。同時,抽屜具有(you)可靠的機(ji)械(xie)聯鎖裝(zhuang)置,有(you)效防止(zhi)了開(kai)(kai)(kai)關在通(tong)電(dian)狀態下帶負荷拉(la)閘(zha),大大提高了使用(yong)的安全性。
ABB低壓開關柜MNS2.0適用于(yu)交流50(60)HZ、額(e)定絕(jue)緣電(dian)(dian)(dian)(dian)壓(ya)和工(gong)(gong)作電(dian)(dian)(dian)(dian)壓(ya)為380(400)V、660v、額(e)定電(dian)(dian)(dian)(dian)流6300A及(ji)(ji)以(yi)下三相(xiang)五線(xian)(xian)制(zhi)的電(dian)(dian)(dian)(dian)力供電(dian)(dian)(dian)(dian)系統。無論是(shi)發(fa)電(dian)(dian)(dian)(dian)廠、變電(dian)(dian)(dian)(dian)所,還(huan)是(shi)工(gong)(gong)礦(kuang)企業、大樓賓館,甚至是(shi)機場、碼頭以(yi)及(ji)(ji)廣播電(dian)(dian)(dian)(dian)視等通(tong)信中心,MNS2.0都(dou)能(neng)(neng)作為發(fa)電(dian)(dian)(dian)(dian)、輸配電(dian)(dian)(dian)(dian)、電(dian)(dian)(dian)(dian)能(neng)(neng)轉換及(ji)(ji)對電(dian)(dian)(dian)(dian)能(neng)(neng)消耗設備(bei)的控制(zhi)核心,并通(tong)過電(dian)(dian)(dian)(dian)容(rong)補償對其主母線(xian)(xian)進行無功補償,實現了電(dian)(dian)(dian)(dian)能(neng)(neng)的高(gao)效利(li)用。
在(zai)使用條(tiao)件方面(mian),ABB低壓開(kai)關柜MNS2.0要求周(zhou)圍空(kong)氣溫度(du)(du)不(bu)(bu)高于+40℃,不(bu)(bu)低于-5℃,且24小時內的平均(jun)溫度(du)(du)不(bu)(bu)高于+35℃。同時,對于相對濕(shi)度(du)(du)的要求也較(jiao)為嚴格(ge),在(zai)最高溫度(du)(du)為+40℃時相對濕(shi)度(du)(du)不(bu)(bu)超過50%,在(zai)較(jiao)低溫度(du)(du)時允許有較(jiao)大的相對濕(shi)度(du)(du),但應避(bi)免(mian)產(chan)生凝露。此外(wai),該開(kai)關柜還(huan)應安裝在(zai)無劇烈(lie)震動(dong)和沖擊(ji),以(yi)及不(bu)(bu)使電器元(yuan)件受到腐蝕的場所(suo),以(yi)確保(bao)其穩定運行。
