施(shi)工用(yong)電(dian)(dian)(dian)配電(dian)(dian)(dian)系統應(ying)設置總配電(dian)(dian)(dian)箱(xiang)(xiang)(xiang)、分配電(dian)(dian)(dian)箱(xiang)(xiang)(xiang)、開關(guan)(guan)箱(xiang)(xiang)(xiang)，并按照“總-分-開”順序(xu)作分級設置，并形成“三級配電(dian)(dian)(dian)”模式。施(shi)工用(yong)配電(dian)(dian)(dian)系統各配電(dian)(dian)(dian)箱(xiang)(xiang)(xiang)、開關(guan)(guan)箱(xiang)(xiang)(xiang)的(de)安(an)裝位置要(yao)合理(li)。總配電(dian)(dian)(dian)箱(xiang)(xiang)(xiang)要(yao)盡(jin)量(liang)靠近變壓器或外電(dian)(dian)(dian)源處，以便電(dian)(dian)(dian)源的(de)引(yin)入(ru)。分配電(dian)(dian)(dian)箱(xiang)(xiang)(xiang)應(ying)盡(jin)量(liang)安(an)裝在用(yong)電(dian)(dian)(dian)設備(bei)或負(fu)(fu)荷(he)相對集中的(de)中心(xin)地帶，確保(bao)三相負(fu)(fu)荷(he)保(bao)持平衡。開關(guan)(guan)箱(xiang)(xiang)(xiang)安(an)裝的(de)位置應(ying)視現(xian)場情(qing)況和(he)工況盡(jin)量(liang)靠近其控制的(de)用(yong)電(dian)(dian)(dian)設備(bei)。

即(ji)地(di)面充(chong)(chong)(chong)電(dian)(dian)(dian)裝置，主要包括專用(yong)(yong)充(chong)(chong)(chong)電(dian)(dian)(dian)機、專用(yong)(yong)充(chong)(chong)(chong)電(dian)(dian)(dian)站、通(tong)用(yong)(yong)充(chong)(chong)(chong)電(dian)(dian)(dian)機、公共場(chang)所用(yong)(yong)充(chong)(chong)(chong)電(dian)(dian)(dian)站等。它可以(yi)滿足各(ge)種電(dian)(dian)(dian)池的(de)各(ge)種充(chong)(chong)(chong)電(dian)(dian)(dian)方(fang)式。通(tong)常(chang)非車載充(chong)(chong)(chong)電(dian)(dian)(dian)器的(de)功率、體積和重(zhong)量均(jun)比較大，以(yi)便能夠適應各(ge)種充(chong)(chong)(chong)電(dian)(dian)(dian)方(fang)式。

充電(dian)樁(zhuang)建設的全面開展，無(wu)疑(yi)會提供巨大的市(shi)場(chang)。北上廣這三大城市(shi)，由(you)于交通(tong)擁(yong)堵，紛紛通(tong)過車(che)(che)牌(pai)(pai)進行購(gou)車(che)(che)限制。不過由(you)于電(dian)動(dong)(dong)(dong)(dong)車(che)(che)的環(huan)保作用(yong)，政府從(cong)上層(ceng)支持電(dian)動(dong)(dong)(dong)(dong)車(che)(che)，因(yin)此北上廣等大城市(shi)都(dou)有相關政策，進入其(qi)相關名錄的電(dian)動(dong)(dong)(dong)(dong)車(che)(che)可以直(zhi)接獲(huo)得車(che)(che)牌(pai)(pai)，這一點從(cong)政策方面刺激了(le)電(dian)動(dong)(dong)(dong)(dong)車(che)(che)的需求。同時，國(guo)內成品油(you)(you)價格上漲(zhang)速度(du)高于下降速度(du)，最終車(che)(che)主承受的是越來越高的油(you)(you)價，電(dian)動(dong)(dong)(dong)(dong)車(che)(che)可以代替(ti)部分(fen)汽油(you)(you)柴油(you)(you)的消耗，降低了(le)這部分(fen)成本。毋庸置疑(yi)充電(dian)樁(zhuang)是新能源戰(zhan)略推進的終端(duan)市(shi)場(chang)，如(ru)能在現在搶占(zhan)先(xian)機(ji)，對資(zi)本的盈利有極(ji)大好處。

1、柜(ju)門(men)(men)(men)離地25mm、2.5mm厚的安(an)裝板，兩邊有(you)20mm寬的U形彎邊，使(shi)得(de)安(an)裝板強度更大，也(ye)便于搬運。2、箱底三(san)塊(kuai)電纜導(dao)入(ru)蓋板，可以(yi)相互替換，移動方便，易(yi)(yi)(yi)于導(dao)入(ru)電纜，易(yi)(yi)(yi)于開孔進線。3、箱門(men)(men)(men)上有(you)接地螺(luo)栓5、承重(zhong)鉸(jiao)鏈(lian)安(an)裝容(rong)易(yi)(yi)(yi)，換柜(ju)門(men)(men)(men)也(ye)容(rong)易(yi)(yi)(yi)。柜(ju)門(men)(men)(men)可開啟(qi)130°。4、塑料滑引(yin)器可利用塑料滑引(yin)器通過導(dao)軌，可從柜(ju)體正面將安(an)裝板推入(ru)柜(ju)內7、堅固的長方形框架不但可以(yi)加強前(qian)門(men)(men)(men)的強度，還(huan)可以(yi)用來固定安(an)裝電器元件（配合門(men)(men)(men)安(an)裝橫條使(shi)用）。5、背板能很(hen)容(rong)易(yi)(yi)(yi)地安(an)裝，用螺(luo)絲固定；還(huan)可換裝柜(ju)門(men)(men)(men)。6、標配MS821鎖(suo)，上、中、下三(san)點鎖(suo)緊柜(ju)門(men)(men)(men)。7、密封(feng)圈：聚氨(an)脂發泡密封(feng)膠(jiao)條，確保(bao)防護等級。

配電箱的進出線選用低壓電纜，尋甸控制柜電纜的選擇應符合技術要求。生產控制柜例如(ru)30kVA、50kVA變壓(ya)器(qi)的(de)配電(dian)(dian)箱的(de)進線(xian)使用(yong)VV22-35×4電(dian)(dian)纜，分(fen)(fen)路(lu)出線(xian)使用(yong)同規格(ge)的(de)VLV22-35×4電(dian)(dian)纜；80kVA、100kVA變壓(ya)器(qi)的(de)配電(dian)(dian)箱的(de)進線(xian)分(fen)(fen)別使用(yong)VV22-50×4、VV22-70×4電(dian)(dian)纜，分(fen)(fen)路(lu)出線(xian)分(fen)(fen)別使用(yong)VLV22-50×4、VLV22-70×4電(dian)(dian)纜,其電(dian)(dian)纜與(yu)銅鋁(lv)接(jie)線(xian)鼻(bi)壓(ya)接(jie)后(hou)再用(yong)螺栓與(yu)配電(dian)(dian)箱內(nei)接(jie)線(xian)樁頭連(lian)接(jie)。

1.了解用(yong)戶(hu)(hu)所(suo)需(xu),根據實際情況選(xuan)擇(ze)最(zui)適合用(yong)戶(hu)(hu)的柜型(xing)。2.盡量采用(yong)國內知名廠家的國產柜型(xing),不能(neng)(neng)盲目選(xuan)擇(ze)技術參(can)數比較高的進口配(pei)電柜,這(zhe)樣易造成資(zi)源浪(lang)費。3.由于進口配(pei)電柜中所(suo)采用(yong)的主(zhu)要元(yuan)器(qi)件的品(pin)牌與柜體(ti)是(shi)一(yi)致的。所(suo)以選(xuan)擇(ze)進口配(pei)電柜時,應注(zhu)意主(zhu)要元(yuan)器(qi)件的參(can)數,它(ta)必須能(neng)(neng)滿足(zu)用(yong)戶(hu)(hu)需(xu)要。
