這類(lei)開(kai)關柜(ju)采用(yong)鋼板制(zhi)成(cheng)(cheng)(cheng)封閉(bi)外(wai)殼，進出線回路(lu)的(de)電(dian)(dian)器(qi)元(yuan)(yuan)件都安裝在(zai)可(ke)抽(chou)出的(de)抽(chou)屜中(zhong)，構成(cheng)(cheng)(cheng)能(neng)完成(cheng)(cheng)(cheng)某一類(lei)供電(dian)(dian)任(ren)務的(de)功(gong)能(neng)單元(yuan)(yuan)。功(gong)能(neng)單元(yuan)(yuan)與母線或電(dian)(dian)纜之間，用(yong)接地的(de)金屬(shu)板或塑料制(zhi)成(cheng)(cheng)(cheng)的(de)功(gong)能(neng)板隔開(kai)，形(xing)成(cheng)(cheng)(cheng)母線、功(gong)能(neng)單元(yuan)(yuan)和電(dian)(dian)纜三個區(qu)域。每(mei)個功(gong)能(neng)單元(yuan)(yuan)之間也(ye)有隔離措施。抽(chou)屜式開(kai)關柜(ju)有較(jiao)高的(de)可(ke)靠性(xing)、安全(quan)性(xing)和互換性(xing)，是(shi)比較(jiao)先進的(de)開(kai)關柜(ju)，開(kai)關柜(ju)多數是(shi)指抽(chou)屜式開(kai)關柜(ju)。它們適用(yong)于要求供電(dian)(dian)可(ke)靠性(xing)較(jiao)高的(de)工礦企業、高層建筑，作(zuo)為集中(zhong)控制(zhi)的(de)配電(dian)(dian)中(zhong)心。

改(gai)進原配電(dian)箱的低壓電(dian)容器(qi)組的接線方式，將其安(an)裝(zhuang)位(wei)置(zhi)由(you)交(jiao)流接觸器(qi)上樁頭，改(gai)成接在配電(dian)箱低壓進線與計量表計之間。防止因運行(xing)中電(dian)容器(qi)電(dian)路發生缺相故(gu)障或電(dian)容器(qi)損壞(huai)時(shi)，造成計量裝(zhuang)置(zhi)計量不準確。此外，電(dian)容器(qi)選擇型號(hao)應為BSMJ系列(lie)產品，以保(bao)證元件質(zhi)量可靠、安(an)全運行(xing)。

充電樁（栓）能實現計時、計電度、計金額充電，專業高壓開關柜可以作為市民購電終端。專業高壓開關柜哪家好同時為提高公共充電(dian)樁(zhuang)（栓）的效率(lv)和實用(yong)性，今后將陸續增(zeng)加一樁(zhuang)（栓）多(duo)充和為電(dian)動(dong)自行車充電(dian)的功能。

快速充(chong)電(dian)(dian)樁（栓(shuan)）設備采用(yong)交(jiao)直流一體的結(jie)構。既(ji)可實現直流充(chong)電(dian)(dian)，也可以交(jiao)流充(chong)電(dian)(dian)。白天(tian)充(chong)電(dian)(dian)業務多的時候，使(shi)用(yong)直流方式進行(xing)(xing)快速充(chong)電(dian)(dian)，當夜間充(chong)電(dian)(dian)站(zhan)用(yong)戶少時可用(yong)交(jiao)流充(chong)電(dian)(dian)進行(xing)(xing)慢充(chong)操(cao)作。
