施(shi)工用(yong)電(dian)(dian)(dian)(dian)配(pei)電(dian)(dian)(dian)(dian)系統(tong)應設置總(zong)配(pei)電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)、分(fen)配(pei)電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)、開關箱(xiang)(xiang)(xiang)，并按照“總(zong)-分(fen)-開”順序作分(fen)級設置，并形成“三(san)級配(pei)電(dian)(dian)(dian)(dian)”模(mo)式。施(shi)工用(yong)配(pei)電(dian)(dian)(dian)(dian)系統(tong)各配(pei)電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)、開關箱(xiang)(xiang)(xiang)的(de)安裝(zhuang)位(wei)置要(yao)合(he)理(li)。總(zong)配(pei)電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)要(yao)盡量靠(kao)近變壓器或(huo)外電(dian)(dian)(dian)(dian)源(yuan)處，以(yi)便電(dian)(dian)(dian)(dian)源(yuan)的(de)引入(ru)。分(fen)配(pei)電(dian)(dian)(dian)(dian)箱(xiang)(xiang)(xiang)應盡量安裝(zhuang)在(zai)用(yong)電(dian)(dian)(dian)(dian)設備或(huo)負荷相對集中(zhong)的(de)中(zhong)心地(di)帶，確(que)保三(san)相負荷保持平衡。開關箱(xiang)(xiang)(xiang)安裝(zhuang)的(de)位(wei)置應視現場情況和工況盡量靠(kao)近其控制的(de)用(yong)電(dian)(dian)(dian)(dian)設備。

暗裝(zhuang)配(pei)電(dian)(dian)箱，配(pei)電(dian)(dian)箱嵌(qian)入(ru)墻(qiang)(qiang)內(nei)安裝(zhuang)，在砌(qi)墻(qiang)(qiang)時預(yu)留孔洞應比配(pei)電(dian)(dian)箱的(de)長和寬(kuan)各大20mm左(zuo)右，預(yu)留的(de)深度(du)為(wei)配(pei)電(dian)(dian)箱厚度(du)加上洞內(nei)壁抹灰的(de)厚度(du)。在圬埋配(pei)電(dian)(dian)箱時，箱體(ti)(ti)與墻(qiang)(qiang)之間填以混凝土(tu)即可把箱體(ti)(ti)固定住。

快速(su)充(chong)(chong)(chong)電(dian)(dian)樁(zhuang)（栓）設備采用(yong)交直流一體的(de)結構。既可實現直流充(chong)(chong)(chong)電(dian)(dian)，也可以交流充(chong)(chong)(chong)電(dian)(dian)。白(bai)天(tian)充(chong)(chong)(chong)電(dian)(dian)業(ye)務(wu)多的(de)時(shi)候，使用(yong)直流方式進(jin)行快速(su)充(chong)(chong)(chong)電(dian)(dian)，當(dang)夜間充(chong)(chong)(chong)電(dian)(dian)站用(yong)戶少時(shi)可用(yong)交流充(chong)(chong)(chong)電(dian)(dian)進(jin)行慢充(chong)(chong)(chong)操作。

對于配電變壓器容量在100kV·A及以上的配電箱體，在箱內散熱窗靠側壁處，玉溪直流充電樁應考慮到安裝溫控繼電器（JU-3型或JU-4超小型溫度繼電器）和軸流風機，直流充電樁廠家安裝在(zai)控制電器板上(shang)方左側面的(de)箱(xiang)體(ti)上(shang)，以(yi)便使箱(xiang)內溫度達到一定值時(shi)（如40℃）能自(zi)動啟動排氣扇，強(qiang)行排出熱(re)量以(yi)使箱(xiang)體(ti)散熱(re)。

電(dian)(dian)(dian)(dian)(dian)(dian)動汽(qi)(qi)車(che)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)樁作為電(dian)(dian)(dian)(dian)(dian)(dian)動汽(qi)(qi)車(che)的(de)(de)能量補(bu)給(gei)裝置，其充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)性能關系(xi)到電(dian)(dian)(dian)(dian)(dian)(dian)池組的(de)(de)使用(yong)壽命、充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時間。這也是消費者在購買電(dian)(dian)(dian)(dian)(dian)(dian)動汽(qi)(qi)車(che)之前最為關心的(de)(de)一個(ge)方(fang)面(mian)之一。實現對(dui)動力電(dian)(dian)(dian)(dian)(dian)(dian)池快速、高效、安全(quan)、合理(li)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)量補(bu)給(gei)是電(dian)(dian)(dian)(dian)(dian)(dian)動汽(qi)(qi)車(che)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器設計的(de)(de)基本原則，另外，還要考慮(lv)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器對(dui)各(ge)種(zhong)動力電(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)適(shi)用(yong)性。
