配電(dian)(dian)箱中的低(di)壓電(dian)(dian)器(qi)，由熔斷(duan)器(qi)、交流接觸器(qi)、剩余電(dian)(dian)流動作(zuo)保護(hu)器(qi)、電(dian)(dian)容(rong)器(qi)及(ji)計(ji)量(liang)表(biao)等組(zu)成。周圍空氣(qi)(qi)溫(wen)度(du)的上限(xian)不(bu)(bu)超(chao)過(guo)40℃；周圍空氣(qi)(qi)溫(wen)度(du)24h的平均(jun)值不(bu)(bu)超(chao)過(guo)35℃；周圍空氣(qi)(qi)溫(wen)度(du)的下限(xian)不(bu)(bu)低(di)于-5℃或-25℃。農網改(gai)造的配電(dian)(dian)箱在室外運行，它不(bu)(bu)但受到陽光的直接照(zhao)射產(chan)生高(gao)溫(wen)，同時(shi)運行中自身(shen)也會產(chan)生熱量(liang)，所以在盛(sheng)夏高(gao)溫(wen)季節，箱體內的溫(wen)度(du)將(jiang)會達(da)到60℃以上，這(zhe)時(shi)的溫(wen)度(du)大大超(chao)過(guo)了這(zhe)些電(dian)(dian)器(qi)規(gui)定的環境(jing)溫(wen)度(du)

改進原配電箱的低壓電容器組的接線方式，充電樁價格將其安裝位置由交流接觸器上樁頭，專業充電樁改成接在配(pei)電(dian)(dian)箱低壓進線與計(ji)量表計(ji)之(zhi)間。防(fang)止因(yin)運(yun)行中電(dian)(dian)容(rong)器電(dian)(dian)路發生缺相故障或電(dian)(dian)容(rong)器損壞時，造成計(ji)量裝置計(ji)量不準(zhun)確。此外，電(dian)(dian)容(rong)器選擇(ze)型(xing)號應為BSMJ系列產品，以保證元件質量可靠、安全運(yun)行。

配電(dian)箱(xiang)是數(shu)據上的海(hai)量(liang)參數(shu)，一般(ban)是構成低壓(ya)林按(an)電(dian)氣接線，要求將開(kai)關設(she)備、測量(liang)儀表(biao)、保(bao)護(hu)電(dian)器和輔助設(she)備組(zu)裝在封閉(bi)或(huo)半(ban)封閉(bi)金屬柜中(zhong)或(huo)屏幅上，構成低壓(ya)配電(dian)箱(xiang)。正常(chang)運行時可借助手(shou)動或(huo)自動開(kai)關接通或(huo)分斷(duan)電(dian)路。
