常(chang)稱開關板(ban)或配電(dian)屏。它是一種有面(mian)(mian)(mian)(mian)板(ban)遮(zhe)攔的開啟式開關柜(ju)，正面(mian)(mian)(mian)(mian)有防(fang)護作用，背面(mian)(mian)(mian)(mian)和側面(mian)(mian)(mian)(mian)仍能(neng)觸及帶電(dian)部分(fen)，防(fang)護等級低，只能(neng)用于對供(gong)電(dian)連續性(xing)(xing)和可靠性(xing)(xing)要求(qiu)較低的工礦企業，作變電(dian)室集(ji)中供(gong)電(dian)用。

1.主母(mu)線(xian)最(zui)大(da)額(e)定(ding)(ding)(ding)(ding)(ding)電(dian)(dian)(dian)流(liu):主母(mu)線(xian)最(zui)大(da)能夠承載的(de)(de)(de)(de)電(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)額(e)定(ding)(ding)(ding)(ding)(ding)值。2.額(e)定(ding)(ding)(ding)(ding)(ding)短(duan)時(shi)(shi)耐(nai)受(shou)(shou)(shou)電(dian)(dian)(dian)流(liu):由生產(chan)廠(chang)家(jia)給出的(de)(de)(de)(de),成(cheng)套設(she)備(bei)中某(mou)條(tiao)電(dian)(dian)(dian)路在(zai)國家(jia)標(biao)準(zhun)GB7251.1-2005中8.2.3規(gui)定(ding)(ding)(ding)(ding)(ding)的(de)(de)(de)(de)試驗條(tiao)件下能安全(quan)承載的(de)(de)(de)(de)短(duan)時(shi)(shi)耐(nai)受(shou)(shou)(shou)電(dian)(dian)(dian)流(liu)方均(jun)根(gen)值。3.峰值短(duan)時(shi)(shi)耐(nai)受(shou)(shou)(shou)電(dian)(dian)(dian)流(liu):在(zai)規(gui)定(ding)(ding)(ding)(ding)(ding)試驗條(tiao)件下,生產(chan)廠(chang)家(jia)規(gui)定(ding)(ding)(ding)(ding)(ding)此電(dian)(dian)(dian)路能夠圓滿地(di)承受(shou)(shou)(shou)的(de)(de)(de)(de)峰值電(dian)(dian)(dian)流(liu)。4.外(wai)殼防護等級:IEC60529-1989標(biao)準(zhun)由成(cheng)套設(she)備(bei)提供的(de)(de)(de)(de)防止觸及(ji)帶電(dian)(dian)(dian)部(bu)件,以及(ji)外(wai)來固體(ti)(ti)的(de)(de)(de)(de)侵入(ru)和液體(ti)(ti)的(de)(de)(de)(de)進入(ru)的(de)(de)(de)(de)等級。具(ju)體(ti)(ti)等級劃分詳見IEC60529標(biao)準(zhun)。5.內部(bu)分隔方式:根(gen)據IEC60529-1989標(biao)準(zhun),為(wei)保護人身(shen)安全(quan),將開關柜(ju)獨立劃分成(cheng)幾個隔室的(de)(de)(de)(de)不同(tong)(tong)方式。不同(tong)(tong)型(xing)號(hao)的(de)(de)(de)(de)配(pei)(pei)電(dian)(dian)(dian)柜(ju)之間(jian)的(de)(de)(de)(de)技術參(can)數(shu)都有很大(da)不同(tong)(tong),而進口(kou)配(pei)(pei)電(dian)(dian)(dian)柜(ju)的(de)(de)(de)(de)技術參(can)數(shu)基本都優于(yu)國產(chan)配(pei)(pei)電(dian)(dian)(dian)柜(ju),但(dan)并不能認為(wei)進口(kou)配(pei)(pei)電(dian)(dian)(dian)柜(ju)就一定(ding)(ding)(ding)(ding)(ding)比國產(chan)配(pei)(pei)電(dian)(dian)(dian)柜(ju)好。

配電箱的進出線選用低壓電纜，成都交流充電樁電纜的選擇應符合技術要求。專業交流充電樁例如30kVA、50kVA變(bian)壓(ya)器(qi)的配(pei)電(dian)(dian)箱的進(jin)線(xian)使用VV22-35×4電(dian)(dian)纜(lan)(lan)，分(fen)(fen)路出線(xian)使用同規格(ge)的VLV22-35×4電(dian)(dian)纜(lan)(lan)；80kVA、100kVA變(bian)壓(ya)器(qi)的配(pei)電(dian)(dian)箱的進(jin)線(xian)分(fen)(fen)別(bie)使用VV22-50×4、VV22-70×4電(dian)(dian)纜(lan)(lan)，分(fen)(fen)路出線(xian)分(fen)(fen)別(bie)使用VLV22-50×4、VLV22-70×4電(dian)(dian)纜(lan)(lan),其電(dian)(dian)纜(lan)(lan)與銅鋁(lv)接(jie)線(xian)鼻壓(ya)接(jie)后再用螺栓(shuan)與配(pei)電(dian)(dian)箱內接(jie)線(xian)樁頭連接(jie)。

充(chong)電(dian)樁(zhuang)建(jian)設的(de)(de)(de)(de)全面開(kai)展，無疑會(hui)提供巨(ju)大(da)的(de)(de)(de)(de)市場。北上(shang)廣(guang)這(zhe)三(san)大(da)城市，由于(yu)(yu)交通擁(yong)堵，紛紛通過車(che)(che)(che)牌(pai)進行購車(che)(che)(che)限(xian)制。不過由于(yu)(yu)電(dian)動(dong)(dong)車(che)(che)(che)的(de)(de)(de)(de)環保作(zuo)用，政(zheng)府(fu)從上(shang)層(ceng)支持電(dian)動(dong)(dong)車(che)(che)(che)，因此北上(shang)廣(guang)等大(da)城市都有(you)相(xiang)關(guan)政(zheng)策，進入其相(xiang)關(guan)名錄的(de)(de)(de)(de)電(dian)動(dong)(dong)車(che)(che)(che)可以(yi)直(zhi)接(jie)獲(huo)得車(che)(che)(che)牌(pai)，這(zhe)一點從政(zheng)策方面刺激了電(dian)動(dong)(dong)車(che)(che)(che)的(de)(de)(de)(de)需求。同(tong)時，國內成品油價(jia)格(ge)上(shang)漲速度(du)(du)高于(yu)(yu)下降速度(du)(du)，最終(zhong)車(che)(che)(che)主(zhu)承受的(de)(de)(de)(de)是(shi)越(yue)來越(yue)高的(de)(de)(de)(de)油價(jia)，電(dian)動(dong)(dong)車(che)(che)(che)可以(yi)代替部分(fen)汽油柴油的(de)(de)(de)(de)消耗(hao)，降低了這(zhe)部分(fen)成本(ben)。毋(wu)庸置疑充(chong)電(dian)樁(zhuang)是(shi)新能源(yuan)戰略推進的(de)(de)(de)(de)終(zhong)端(duan)市場，如能在現在搶占先機，對資本(ben)的(de)(de)(de)(de)盈利有(you)極大(da)好處(chu)。
