1.主(zhu)母(mu)線最(zui)(zui)大(da)額定(ding)(ding)電(dian)(dian)(dian)流:主(zhu)母(mu)線最(zui)(zui)大(da)能(neng)(neng)(neng)夠承載(zai)的(de)(de)(de)電(dian)(dian)(dian)流的(de)(de)(de)額定(ding)(ding)值(zhi)(zhi)。2.額定(ding)(ding)短時耐受(shou)電(dian)(dian)(dian)流:由生(sheng)產(chan)廠家(jia)給出的(de)(de)(de),成套設備(bei)中(zhong)某條(tiao)電(dian)(dian)(dian)路(lu)在(zai)國(guo)家(jia)標(biao)準(zhun)GB7251.1-2005中(zhong)8.2.3規定(ding)(ding)的(de)(de)(de)試驗(yan)條(tiao)件(jian)下(xia)能(neng)(neng)(neng)安(an)全承載(zai)的(de)(de)(de)短時耐受(shou)電(dian)(dian)(dian)流方均根值(zhi)(zhi)。3.峰(feng)值(zhi)(zhi)短時耐受(shou)電(dian)(dian)(dian)流:在(zai)規定(ding)(ding)試驗(yan)條(tiao)件(jian)下(xia),生(sheng)產(chan)廠家(jia)規定(ding)(ding)此電(dian)(dian)(dian)路(lu)能(neng)(neng)(neng)夠圓滿地承受(shou)的(de)(de)(de)峰(feng)值(zhi)(zhi)電(dian)(dian)(dian)流。4.外(wai)殼(ke)防護等(deng)(deng)級:IEC60529-1989標(biao)準(zhun)由成套設備(bei)提供的(de)(de)(de)防止觸及帶電(dian)(dian)(dian)部件(jian),以及外(wai)來固體(ti)的(de)(de)(de)侵(qin)入和液體(ti)的(de)(de)(de)進入的(de)(de)(de)等(deng)(deng)級。具體(ti)等(deng)(deng)級劃分(fen)詳見IEC60529標(biao)準(zhun)。5.內部分(fen)隔(ge)方式:根據(ju)IEC60529-1989標(biao)準(zhun),為保護人(ren)身安(an)全,將開關柜(ju)獨立劃分(fen)成幾個(ge)隔(ge)室的(de)(de)(de)不同(tong)(tong)方式。不同(tong)(tong)型號的(de)(de)(de)配(pei)電(dian)(dian)(dian)柜(ju)之間的(de)(de)(de)技術(shu)參數都有很大(da)不同(tong)(tong),而進口配(pei)電(dian)(dian)(dian)柜(ju)的(de)(de)(de)技術(shu)參數基(ji)本都優于國(guo)產(chan)配(pei)電(dian)(dian)(dian)柜(ju),但并不能(neng)(neng)(neng)認為進口配(pei)電(dian)(dian)(dian)柜(ju)就(jiu)一定(ding)(ding)比國(guo)產(chan)配(pei)電(dian)(dian)(dian)柜(ju)好。

配電(dian)箱(xiang)(xiang)中(zhong)(zhong)的低壓(ya)電(dian)器，由熔斷器、交(jiao)流接(jie)觸器、剩(sheng)余(yu)電(dian)流動作保護器、電(dian)容器及計(ji)量(liang)表等組成。周圍空(kong)氣(qi)溫(wen)(wen)度的上限不(bu)超(chao)過(guo)(guo)40℃；周圍空(kong)氣(qi)溫(wen)(wen)度24h的平均(jun)值不(bu)超(chao)過(guo)(guo)35℃；周圍空(kong)氣(qi)溫(wen)(wen)度的下限不(bu)低于-5℃或-25℃。農網(wang)改造(zao)的配電(dian)箱(xiang)(xiang)在室外運行，它不(bu)但受到(dao)陽光的直接(jie)照射產生(sheng)高(gao)溫(wen)(wen)，同時運行中(zhong)(zhong)自(zi)身也會產生(sheng)熱(re)量(liang)，所以(yi)在盛夏高(gao)溫(wen)(wen)季節，箱(xiang)(xiang)體內的溫(wen)(wen)度將會達(da)到(dao)60℃以(yi)上，這時的溫(wen)(wen)度大大超(chao)過(guo)(guo)了(le)這些電(dian)器規定的環境溫(wen)(wen)度

配電箱(xiang)是(shi)數(shu)據(ju)上的海量(liang)參數(shu)，一般是(shi)構成低壓林按電氣接線，要求將開關(guan)設備、測量(liang)儀表、保護電器和輔(fu)助設備組裝在封閉(bi)或半封閉(bi)金屬柜(ju)中(zhong)或屏幅(fu)上，構成低壓配電箱(xiang)。正常(chang)運行(xing)時可借助手動或自(zi)動開關(guan)接通或分(fen)斷電路。

電動汽車充電樁（栓）的控制電路主要由嵌入式ARM處理器完成，臨滄開關柜用戶可自助刷卡進行用戶鑒權、余額查詢、計費查詢等功能，也可提供語音輸出接口，實現語音交互。開關柜價格用戶可根(gen)據液(ye)晶顯示屏指(zhi)示選擇4種充(chong)電模式：包括(kuo)按(an)時計費充(chong)電、按(an)電量充(chong)電、自動充(chong)滿(man)、按(an)里程充(chong)電等
