指(zhi)除安(an)(an)裝面(mian)外(wai)(wai)，其(qi)它(ta)所有側面(mian)都被封(feng)(feng)閉起(qi)來(lai)的一(yi)種低壓開關柜(ju)。這種柜(ju)子的開關、保護和(he)監測控(kong)制(zhi)(zhi)(zhi)等電(dian)氣(qi)元件(jian)，均安(an)(an)裝在(zai)一(yi)個用(yong)鋼或絕(jue)緣材料制(zhi)(zhi)(zhi)成的封(feng)(feng)閉外(wai)(wai)殼內(nei)，可(ke)靠墻或離(li)(li)墻安(an)(an)裝。柜(ju)內(nei)每條回路(lu)之間可(ke)以不加隔(ge)離(li)(li)措(cuo)施，也可(ke)以采用(yong)接地的金屬板或絕(jue)緣板進(jin)行隔(ge)離(li)(li)。通(tong)常(chang)門(men)與主開關操(cao)作(zuo)(zuo)有機(ji)械聯鎖。另外(wai)(wai)還有防(fang)護式臺型開關柜(ju)（即(ji)控(kong)制(zhi)(zhi)(zhi)臺）】面(mian)板上裝有控(kong)制(zhi)(zhi)(zhi)、測量、信號等電(dian)器。防(fang)護式開關柜(ju)主要用(yong)作(zuo)(zuo)工藝(yi)現場的配電(dian)裝置(zhi)。

配電箱是數據上的海量參數，生產配電箱一般是構成低壓林按電氣接線，要求將開關設備、測量儀表、配電箱價格保護電器和(he)輔助設備組裝(zhuang)在封閉(bi)或(huo)(huo)半封閉(bi)金(jin)屬柜中或(huo)(huo)屏幅上，構成(cheng)低(di)壓(ya)配電箱(xiang)。正常(chang)運行(xing)時可借助手動或(huo)(huo)自動開關(guan)接(jie)通或(huo)(huo)分斷(duan)電路(lu)。

1.了解用(yong)(yong)戶(hu)所(suo)需,根據實際(ji)情況選擇(ze)最(zui)適(shi)合用(yong)(yong)戶(hu)的(de)柜型(xing)。2.盡(jin)量采(cai)用(yong)(yong)國內知(zhi)名廠(chang)家的(de)國產柜型(xing),不能盲目選擇(ze)技(ji)術參數(shu)比較高的(de)進(jin)(jin)口配(pei)電(dian)柜,這樣易造成資源(yuan)浪(lang)費。3.由于進(jin)(jin)口配(pei)電(dian)柜中所(suo)采(cai)用(yong)(yong)的(de)主(zhu)要(yao)元器(qi)件的(de)品牌與柜體(ti)是(shi)一致的(de)。所(suo)以選擇(ze)進(jin)(jin)口配(pei)電(dian)柜時,應注意(yi)主(zhu)要(yao)元器(qi)件的(de)參數(shu),它必須能滿足(zu)用(yong)(yong)戶(hu)需要(yao)。

配電(dian)(dian)(dian)箱(xiang)的(de)進出線(xian)(xian)(xian)(xian)選用(yong)(yong)低壓(ya)電(dian)(dian)(dian)纜(lan)，電(dian)(dian)(dian)纜(lan)的(de)選擇(ze)應符合技(ji)術要求。例(li)如(ru)30kVA、50kVA變(bian)壓(ya)器的(de)配電(dian)(dian)(dian)箱(xiang)的(de)進線(xian)(xian)(xian)(xian)使(shi)用(yong)(yong)VV22-35×4電(dian)(dian)(dian)纜(lan)，分(fen)路出線(xian)(xian)(xian)(xian)使(shi)用(yong)(yong)同規格的(de)VLV22-35×4電(dian)(dian)(dian)纜(lan)；80kVA、100kVA變(bian)壓(ya)器的(de)配電(dian)(dian)(dian)箱(xiang)的(de)進線(xian)(xian)(xian)(xian)分(fen)別使(shi)用(yong)(yong)VV22-50×4、VV22-70×4電(dian)(dian)(dian)纜(lan)，分(fen)路出線(xian)(xian)(xian)(xian)分(fen)別使(shi)用(yong)(yong)VLV22-50×4、VLV22-70×4電(dian)(dian)(dian)纜(lan),其電(dian)(dian)(dian)纜(lan)與銅鋁接(jie)線(xian)(xian)(xian)(xian)鼻壓(ya)接(jie)后再用(yong)(yong)螺栓與配電(dian)(dian)(dian)箱(xiang)內接(jie)線(xian)(xian)(xian)(xian)樁頭連(lian)接(jie)。

電(dian)(dian)動汽車充(chong)(chong)(chong)電(dian)(dian)樁作為電(dian)(dian)動汽車的(de)能量補給(gei)裝置(zhi)，其充(chong)(chong)(chong)電(dian)(dian)性能關系到(dao)電(dian)(dian)池組的(de)使用(yong)壽命(ming)、充(chong)(chong)(chong)電(dian)(dian)時間。這(zhe)也是(shi)消費(fei)者在購買電(dian)(dian)動汽車之前最(zui)為關心(xin)的(de)一(yi)個方面之一(yi)。實現對動力(li)(li)電(dian)(dian)池快速、高效、安全(quan)、合理的(de)電(dian)(dian)量補給(gei)是(shi)電(dian)(dian)動汽車充(chong)(chong)(chong)電(dian)(dian)器設計的(de)基(ji)本原則，另外，還要(yao)考(kao)慮(lv)充(chong)(chong)(chong)電(dian)(dian)器對各種動力(li)(li)電(dian)(dian)池的(de)適(shi)用(yong)性。
