按照安裝地點，可分為(wei)(wei)公(gong)共(gong)充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)和專(zhuan)用充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)。 公(gong)共(gong)充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)是建(jian)(jian)(jian)設在(zai)公(gong)共(gong)停(ting)(ting)車場（庫(ku)）結合停(ting)(ting)車泊位，為(wei)(wei)社會(hui)車輛提供公(gong)共(gong)充(chong)(chong)電(dian)(dian)(dian)(dian)服(fu)務的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)。 專(zhuan)用充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)是建(jian)(jian)(jian)設單(dan)位（企業）自有(you)(you)停(ting)(ting)車場（庫(ku)），為(wei)(wei)單(dan)位（企業）內部(bu)人(ren)(ren)員使用的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)。 自用充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)是建(jian)(jian)(jian)設在(zai)個人(ren)(ren)自有(you)(you)車位（庫(ku)），為(wei)(wei)私人(ren)(ren)用戶提供充(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)。 充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)一(yi)般結合停(ting)(ting)車場（庫(ku)）的(de)(de)停(ting)(ting)車位建(jian)(jian)(jian)設。安裝在(zai)戶外的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)防(fang)(fang)護(hu)等級不應低(di)于IP54。安裝在(zai)戶內的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)防(fang)(fang)護(hu)等級不應低(di)于IP32。

昨日一大早(zao)，焦作(zuo)供(gong)電(dian)公(gong)司的維修人員便(bian)來到塔北(bei)路農(nong)貿市場，在架(jia)設(she)過低的配電(dian)箱周圍拉起警戒線，動用叉車等機械，對存在安(an)全隱患的配電(dian)箱重新架(jia)設(she)。

常稱開(kai)關板或(huo)配電屏(ping)。它是一種有(you)面(mian)(mian)板遮攔的開(kai)啟式開(kai)關柜，正(zheng)面(mian)(mian)有(you)防護作用(yong)(yong)，背面(mian)(mian)和側面(mian)(mian)仍能觸及(ji)帶電部分，防護等級低，只能用(yong)(yong)于對供電連續性和可靠(kao)性要求較(jiao)低的工礦(kuang)企業，作變電室集中供電用(yong)(yong)。

施工用電配電系統應設置總配電箱、分配電箱、開關箱，并按照“總-分-開”順序作分級設置，并形成“三級配電”模式。訂做便攜式充電樁施工用配電系統各配電箱、開關箱的安裝位置要合理。便攜式充電樁價格總配電(dian)箱要盡量靠(kao)近(jin)變壓器或外電(dian)源處，以便電(dian)源的(de)引入(ru)。分配電(dian)箱應盡量安裝在用電(dian)設備或負(fu)荷(he)相對集中(zhong)的(de)中(zhong)心地帶，確(que)保三相負(fu)荷(he)保持平衡。開關箱安裝的(de)位置應視現場情況(kuang)和工(gong)況(kuang)盡量靠(kao)近(jin)其控(kong)制的(de)用電(dian)設備。

搬運材料、傳遞工(gong)具、拆(chai)換部件(jian)、今天(tian)你(ni)去搶修到我來安裝、你(ni)累(lei)了換我來。就這樣，一個(ge)接著(zhu)一個(ge)的(de)配(pei)電(dian)箱(xiang)在師(shi)傅們輪換著(zhu)的(de)手掌下(xia)組裝了起來。經(jing)過3天(tian)的(de)努力，所(suo)需更換的(de)配(pei)電(dian)箱(xiang)已經(jing)全部組裝完畢(bi)，為本次更換配(pei)電(dian)箱(xiang)工(gong)作做好了前期準(zhun)備(bei)，大家(jia)的(de)臉(lian)上(shang)露出了開心的(de)笑容(rong)。
