配電箱原理(li)：

配(pei)電(dian)(dian)(dian)箱是按(an)電(dian)(dian)(dian)氣接線要求將開關設備、測(ce)量儀表、保護(hu)電(dian)(dian)(dian)器和輔助設備組裝在封閉或(huo)半封閉金屬柜中或(huo)屏幅上，構成低壓配(pei)電(dian)(dian)(dian)箱。正常運(yun)(yun)(yun)行(xing)時可借(jie)助手動或(huo)自動開關接通或(huo)分(fen)斷(duan)電(dian)(dian)(dian)路(lu)。故障或(huo)不(bu)正常運(yun)(yun)(yun)行(xing)時借(jie)助保護(hu)電(dian)(dian)(dian)器切斷(duan)電(dian)(dian)(dian)路(lu)或(huo)報警。借(jie)測(ce)量儀表可顯示(shi)運(yun)(yun)(yun)行(xing)中的(de)各種參數(shu)，還(huan)可對某些電(dian)(dian)(dian)氣參數(shu)進行(xing)調整，對偏離正常工作狀態進行(xing)提示(shi)或(huo)發出信號。

配電箱用途：

配電(dian)(dian)(dian)箱(xiang)具有體積(ji)小、安裝簡便，技術(shu)性能(neng)(neng)特(te)殊、位置固定(ding)，配置功能(neng)(neng)獨(du)特(te)、不受場(chang)地限制，應(ying)用(yong)比較普(pu)遍，操(cao)作穩定(ding)可靠，空間利用(yong)率高(gao)，占地少且(qie)具有環(huan)保效應(ying)的(de)(de)(de)(de)特(te)點。是(shi)指揮(hui)供電(dian)(dian)(dian)線(xian)路中各種元器件合(he)理分配電(dian)(dian)(dian)能(neng)(neng)的(de)(de)(de)(de)控制中心，是(shi)可靠接納上(shang)端電(dian)(dian)(dian)源，正確饋出荷載(zai)電(dian)(dian)(dian)能(neng)(neng)的(de)(de)(de)(de)控制環(huan)節，也是(shi)獲取用(yong)戶對(dui)供電(dian)(dian)(dian)質量滿意(yi)與否的(de)(de)(de)(de)關鍵。提高(gao)動(dong)力配電(dian)(dian)(dian)箱(xiang)的(de)(de)(de)(de)操(cao)作可靠性，是(shi)創(chuang)優質工程的(de)(de)(de)(de)目標。 配電(dian)(dian)(dian)箱(xiang)的(de)(de)(de)(de)用(yong)途(tu)：合(he)理的(de)(de)(de)(de)分配電(dian)(dian)(dian)能(neng)(neng)，方便對(dui)電(dian)(dian)(dian)路的(de)(de)(de)(de)開合(he)操(cao)作。有較高(gao)的(de)(de)(de)(de)安全防護等級，能(neng)(neng)直觀的(de)(de)(de)(de)顯(xian)示電(dian)(dian)(dian)路的(de)(de)(de)(de)導通狀態。
