配電箱是數據上的海量參數,一般是構成低壓林按電氣接線,要求將開關設備、測量儀表、保護電器和輔助設備組裝在封閉或半封閉金屬柜中或屏幅上,構成低壓配電箱。正常運行時可借助手動或自動開關接通或分斷電路。配(pei)電(dian)(dian)(dian)箱是(shi)按電(dian)(dian)(dian)氣(qi)接(jie)線要求(qiu)將開關(guan)設備、測(ce)(ce)量儀表、保(bao)護電(dian)(dian)(dian)器(qi)和輔助(zhu)(zhu)設備組裝在封閉(bi)(bi)或(huo)(huo)(huo)半封閉(bi)(bi)金屬(shu)柜(ju)中(zhong)或(huo)(huo)(huo)屏幅(fu)上,構成低壓(ya)配(pei)電(dian)(dian)(dian)箱。正常(chang)運行(xing)(xing)(xing)時(shi)(shi)可借助(zhu)(zhu)手動或(huo)(huo)(huo)自動開關(guan)接(jie)通或(huo)(huo)(huo)分(fen)斷電(dian)(dian)(dian)路。故障或(huo)(huo)(huo)不正常(chang)運行(xing)(xing)(xing)時(shi)(shi)借助(zhu)(zhu)保(bao)護電(dian)(dian)(dian)器(qi)切斷電(dian)(dian)(dian)路或(huo)(huo)(huo)報警。借測(ce)(ce)量儀表可顯(xian)示運行(xing)(xing)(xing)中(zhong)的(de)各種參數,還可對某些電(dian)(dian)(dian)氣(qi)參數進(jin)行(xing)(xing)(xing)調整,對偏離正常(chang)工作狀態進(jin)行(xing)(xing)(xing)提示或(huo)(huo)(huo)發出信號。
首先(xian)目(mu)前市場(chang)上的(de)(de)配(pei)電(dian)(dian)(dian)箱(xiang)(xiang)主要有(you)金屬(shu)外殼(ke)和塑料外殼(ke)兩種,結構上有(you)暗裝(zhuang)(zhuang)式(shi)和明裝(zhuang)(zhuang)式(shi)兩類(lei),因此在選(xuan)(xuan)擇(ze)時,根據(ju)實(shi)際需要選(xuan)(xuan)擇(ze),不(bu)管是選(xuan)(xuan)擇(ze)哪種類(lei)型的(de)(de)配(pei)電(dian)(dian)(dian)箱(xiang)(xiang),其箱(xiang)(xiang)體必須完好(hao)無損,配(pei)電(dian)(dian)(dian)箱(xiang)(xiang)門板(ban)應(ying)有檢查透(tou)明窗。在國內供(gong)配(pei)電(dian)(dian)系統中(zhong),配(pei)電(dian)(dian)箱的型號有(you)很多種,它們的箱體(ti)結構﹑技術參數尺寸都有(you)所不同,并(bing)且根據使(shi)用場合的不同,配(pei)電(dian)(dian)箱尺寸有(you)很多,因此配(pei)電(dian)(dian)箱價格也相差(cha)較大。
