隨著電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)子技術(shu)和(he)(he)變流(liu)控(kong)制技術(shu)的(de)(de)飛(fei)速(su)發展，高精(jing)度可控(kong)變流(liu)技術(shu)的(de)(de)成熟和(he)(he)普及，分階(jie)段恒(heng)(heng)流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)模式(shi)已經基本被充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)和(he)(he)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓連續變化(hua)的(de)(de)恒(heng)(heng)壓限流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)模式(shi)取代。主(zhu)導充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)工藝的(de)(de)還是恒(heng)(heng)壓限流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)模式(shi)。接(jie)觸式(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)最大問題(ti)在(zai)于(yu)它的(de)(de)安全性(xing)(xing)和(he)(he)通用性(xing)(xing)。為了使(shi)它滿足嚴格的(de)(de)安全充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)標準，必須在(zai)電(dian)(dian)(dian)(dian)(dian)路上采用許多措施使(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)設(she)備能夠在(zai)各種環境下安全充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，恒(heng)(heng)壓限流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)和(he)(he)分階(jie)段恒(heng)(heng)流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)均屬(shu)于(yu)接(jie)觸式(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)技術(shu)。新型的(de)(de)電(dian)(dian)(dian)(dian)(dian)動汽車感(gan)應充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)技術(shu)發展很快(kuai)。

常稱(cheng)開關板或配電(dian)屏。它是一種有(you)面板遮攔(lan)的(de)開啟(qi)式(shi)開關柜，正面有(you)防護(hu)作(zuo)用，背面和(he)側(ce)面仍能觸及帶電(dian)部分，防護(hu)等(deng)級低，只能用于(yu)對供電(dian)連續性(xing)(xing)和(he)可靠性(xing)(xing)要(yao)求(qiu)較低的(de)工(gong)礦企業(ye)，作(zuo)變電(dian)室集中供電(dian)用。

施工(gong)用(yong)(yong)電(dian)(dian)(dian)配電(dian)(dian)(dian)系統(tong)應設置總(zong)配電(dian)(dian)(dian)箱(xiang)(xiang)(xiang)、分(fen)(fen)配電(dian)(dian)(dian)箱(xiang)(xiang)(xiang)、開關箱(xiang)(xiang)(xiang)，并按照“總(zong)-分(fen)(fen)-開”順序(xu)作分(fen)(fen)級設置，并形成“三(san)級配電(dian)(dian)(dian)”模式(shi)。施工(gong)用(yong)(yong)配電(dian)(dian)(dian)系統(tong)各配電(dian)(dian)(dian)箱(xiang)(xiang)(xiang)、開關箱(xiang)(xiang)(xiang)的安裝位置要合理(li)。總(zong)配電(dian)(dian)(dian)箱(xiang)(xiang)(xiang)要盡(jin)量靠近變(bian)壓(ya)器或外電(dian)(dian)(dian)源處，以便(bian)電(dian)(dian)(dian)源的引入(ru)。分(fen)(fen)配電(dian)(dian)(dian)箱(xiang)(xiang)(xiang)應盡(jin)量安裝在用(yong)(yong)電(dian)(dian)(dian)設備或負荷(he)相(xiang)對集中的中心地(di)帶，確(que)保(bao)三(san)相(xiang)負荷(he)保(bao)持平衡(heng)。開關箱(xiang)(xiang)(xiang)安裝的位置應視現場情況和工(gong)況盡(jin)量靠近其(qi)控制(zhi)的用(yong)(yong)電(dian)(dian)(dian)設備。

如今(jin)，除了(le)北京、天(tian)津(jin)、上海(hai)、杭州等(deng)地相繼出(chu)臺充(chong)(chong)電(dian)(dian)(dian)設施(shi)建(jian)設規劃(hua)之外，不少地方(fang)政府(fu)還提出(chu)新(xin)建(jian)小區(qu)配套(tao)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)的(de)(de)新(xin)思路，這(zhe)不僅(jin)可緩解電(dian)(dian)(dian)動汽(qi)車(che)使用者的(de)(de)“里程焦慮”問題，更將(jiang)大幅、直接(jie)拉動充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)生產企(qi)業的(de)(de)銷量。充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)作為新(xin)能(neng)源汽(qi)車(che)產業鏈的(de)(de)重要(yao)下游(you)支(zhi)柱行(xing)業，其市場(chang)化前(qian)景(jing)似乎相當樂觀(guan)。盡(jin)管行(xing)業前(qian)景(jing)被(bei)一致看好，但(dan)目前(qian)電(dian)(dian)(dian)動汽(qi)車(che)市場(chang)的(de)(de)發展并未完全成熟。標準、規劃(hua)和土地三大問題攔在充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)建(jian)設的(de)(de)路前(qian)，成體系(xi)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)建(jian)設并不一帆風順。

指除安裝面外，其它所有側面都被封閉起來的一種低壓開關柜。這種柜子的開關、保護和監測控制等電氣元件，文山變壓器均安裝在一個用鋼或絕緣材料制成的封閉外殼內，可靠墻或離墻安裝。變壓器哪家好柜內(nei)每條回路之間(jian)可以(yi)不加隔離(li)措施，也可以(yi)采用接(jie)地的(de)金屬板(ban)(ban)或絕(jue)緣板(ban)(ban)進行隔離(li)。通常門與主(zhu)開(kai)(kai)關(guan)操作(zuo)有(you)機械(xie)聯鎖。另外還有(you)防護式臺(tai)型開(kai)(kai)關(guan)柜（即控(kong)制臺(tai)）】面板(ban)(ban)上裝有(you)控(kong)制、測量、信(xin)號等電器。防護式開(kai)(kai)關(guan)柜主(zhu)要用作(zuo)工藝現場的(de)配電裝置。

充(chong)(chong)(chong)電(dian)服(fu)務管理(li)(li)(li)平臺主要有三個功能：充(chong)(chong)(chong)電(dian)管理(li)(li)(li)、充(chong)(chong)(chong)電(dian)運營、綜(zong)合(he)查詢。充(chong)(chong)(chong)電(dian)管理(li)(li)(li)對系統(tong)涉及到的基礎數據進行集中式管理(li)(li)(li)，如電(dian)動汽車(che)信(xin)息(xi)、電(dian)池信(xin)息(xi)、用戶卡信(xin)息(xi)、充(chong)(chong)(chong)電(dian)樁（栓(shuan)）信(xin)息(xi)；充(chong)(chong)(chong)電(dian)運營主要對用戶充(chong)(chong)(chong)電(dian)進行計費管理(li)(li)(li)；綜(zong)合(he)查詢指對管理(li)(li)(li)及運營的數據進行綜(zong)合(he)分析(xi)查詢。
