這類開關(guan)柜(ju)采用鋼板制成封閉外殼，進(jin)出線(xian)回路(lu)的(de)電(dian)(dian)器元(yuan)件都安裝在可(ke)抽(chou)(chou)出的(de)抽(chou)(chou)屜(ti)(ti)中(zhong)，構成能(neng)(neng)完成某一類供(gong)電(dian)(dian)任務的(de)功(gong)能(neng)(neng)單元(yuan)。功(gong)能(neng)(neng)單元(yuan)與母線(xian)或(huo)電(dian)(dian)纜之(zhi)間，用接地的(de)金(jin)屬板或(huo)塑料制成的(de)功(gong)能(neng)(neng)板隔(ge)開，形成母線(xian)、功(gong)能(neng)(neng)單元(yuan)和電(dian)(dian)纜三(san)個(ge)(ge)區域。每(mei)個(ge)(ge)功(gong)能(neng)(neng)單元(yuan)之(zhi)間也有(you)隔(ge)離(li)措施。抽(chou)(chou)屜(ti)(ti)式(shi)(shi)開關(guan)柜(ju)有(you)較(jiao)高(gao)的(de)可(ke)靠(kao)性(xing)、安全(quan)性(xing)和互換性(xing)，是比較(jiao)先(xian)進(jin)的(de)開關(guan)柜(ju)，開關(guan)柜(ju)多數是指抽(chou)(chou)屜(ti)(ti)式(shi)(shi)開關(guan)柜(ju)。它(ta)們適用于(yu)要求供(gong)電(dian)(dian)可(ke)靠(kao)性(xing)較(jiao)高(gao)的(de)工礦企業、高(gao)層建(jian)筑，作為集中(zhong)控(kong)制的(de)配(pei)電(dian)(dian)中(zhong)心。

配電箱中的低壓電器，由熔斷器、交流接觸器、剩余電流動作保護器、電容器及計量表等組成。周圍空氣溫度的上限不超過40℃；周圍空氣溫度24h的平均值不超過35℃；周圍空氣溫度的下限不低于-5℃或-25℃。呈貢電表箱農網改造的配電箱在室外運行，訂做電表箱它不但受到陽光的直接(jie)照射(she)產生(sheng)高溫，同時(shi)運(yun)行(xing)中自(zi)身也會產生(sheng)熱量，所(suo)以(yi)在(zai)盛(sheng)夏(xia)高溫季節，箱(xiang)體內的溫度將會達到60℃以(yi)上，這(zhe)時(shi)的溫度大大超過了(le)這(zhe)些電(dian)器規(gui)定的環境溫度

在農(nong)網改(gai)造中當(dang)時由于需(xu)求的配(pei)電箱(xiang)數量(liang)大、施工期短，配(pei)電箱(xiang)廠需(xu)要有關低壓電器的供貨時間急且數量(liang)多，因而產(chan)生(sheng)了(le)對產(chan)品質量(liang)的要求不嚴格的現象，造成(cheng)了(le)一些(xie)產(chan)品投(tou)入運(yun)(yun)行(xing)后不久就發生(sheng)故障(zhang)。如(ru)有些(xie)型號交流接(jie)觸(chu)器在配(pei)電箱(xiang)投(tou)運(yun)(yun)后不久，就因接(jie)觸(chu)器合(he)閘(zha)線圈燒壞，而無法運(yun)(yun)行(xing)。

配(pei)電(dian)(dian)箱具有(you)體積小、安裝簡便，技術性能特殊、位置固定(ding)，配(pei)置功(gong)能獨(du)特、不(bu)受場(chang)地限制，應用(yong)比較普遍，操(cao)作穩定(ding)可(ke)(ke)靠，空間利用(yong)率(lv)高，占(zhan)地少且(qie)具有(you)環保效應的(de)(de)特點。是(shi)(shi)指(zhi)揮(hui)供電(dian)(dian)線路中各種(zhong)元(yuan)器件合理分配(pei)電(dian)(dian)能的(de)(de)控制中心(xin)，是(shi)(shi)可(ke)(ke)靠接納上端(duan)電(dian)(dian)源，正確饋出荷載電(dian)(dian)能的(de)(de)控制環節，也(ye)是(shi)(shi)獲取用(yong)戶對供電(dian)(dian)質量滿意(yi)與否的(de)(de)關鍵。提(ti)高動力配(pei)電(dian)(dian)箱的(de)(de)操(cao)作可(ke)(ke)靠性，是(shi)(shi)創優(you)質工程的(de)(de)目標。

由于(yu)電(dian)(dian)(dian)(dian)動汽(qi)車每天需(xu)要補充(chong)(chong)(chong)大(da)(da)(da)(da)量電(dian)(dian)(dian)(dian)能，經(jing)(jing)營充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)就可(ke)以獲得(de)巨大(da)(da)(da)(da)的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)服務(wu)收(shou)益。相對于(yu)加油站(zhan)(zhan)(zhan)，電(dian)(dian)(dian)(dian)能比(bi)較安(an)全和方便，可(ke)在各(ge)地大(da)(da)(da)(da)量安(an)裝設置(zhi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)。根據(ju)投(tou)(tou)資(zi)規模，小(xiao)到社區慢(man)速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)樁，大(da)(da)(da)(da)到公路(lu)快速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)，單(dan)站(zhan)(zhan)(zhan)經(jing)(jing)營，組網經(jing)(jing)營均可(ke)。對于(yu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)市(shi)場(chang)的(de)開放，國家電(dian)(dian)(dian)(dian)網以后可(ke)能更多地會偏向服務(wu)和電(dian)(dian)(dian)(dian)力供應(ying)，讓(rang)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)建設更充(chong)(chong)(chong)分地與市(shi)場(chang)融合，大(da)(da)(da)(da)家都將是(shi)同一個市(shi)場(chang)的(de)競爭者。因此提(ti)前準備、提(ti)前規劃，對從事(shi)電(dian)(dian)(dian)(dian)池生(sheng)產的(de)企業來(lai)說很重要。充(chong)(chong)(chong)換電(dian)(dian)(dian)(dian)市(shi)場(chang)，政(zheng)策有傾斜(xie)，市(shi)場(chang)有潛力，投(tou)(tou)資(zi)又少(shao)，將面臨較大(da)(da)(da)(da)的(de)商機(ji)。
