在農(nong)網改(gai)造中(zhong)當時由于需求(qiu)的(de)配電(dian)(dian)箱(xiang)數(shu)量大(da)、施工期短，配電(dian)(dian)箱(xiang)廠需要有(you)關低壓電(dian)(dian)器(qi)(qi)的(de)供(gong)貨時間(jian)急且數(shu)量多，因而產(chan)生了對(dui)產(chan)品質量的(de)要求(qiu)不嚴格的(de)現象，造成了一些產(chan)品投入運(yun)行(xing)后不久(jiu)就發生故障(zhang)。如有(you)些型號交(jiao)流接觸(chu)器(qi)(qi)在配電(dian)(dian)箱(xiang)投運(yun)后不久(jiu)，就因接觸(chu)器(qi)(qi)合(he)閘線圈燒壞(huai)，而無法運(yun)行(xing)。

充電(dian)機內(nei)印刷線路板(ban)、 接插件(jian)等(deng)電(dian)路應進(jin)行防(fang)潮濕(shi)、防(fang)霉(mei)變、防(fang)鹽(yan)霧處理，其中防(fang)鹽(yan)霧腐蝕能(neng)力(li)滿足 GB/T 4797.6-1995《電(dian)工電(dian)子產(chan)品自然(ran)環境條(tiao)件(jian) 塵(chen)、沙、鹽(yan)霧》中表9的要(yao)求，使充電(dian)機能(neng)在室外潮濕(shi)、含鹽(yan)霧的環境下正常運(yun)行。

必須選用符(fu)合GB 6829《剩余電(dian)流動作(zuo)保護(hu)(hu)器(qi)的一般(ban)要求》標準、并經中(zhong)國電(dian)工產(chan)品(pin)認證委(wei)員會認證合格(ge)的產(chan)品(pin)。可選用類似(si)LJM（J）系列節(jie)電(dian)型、且是低靈敏度的延時(shi)型保護(hu)(hu)器(qi)。保護(hu)(hu)器(qi)裝(zhuang)置(zhi)的方式要符(fu)合國家GB13955-2005《剩余電(dian)流動作(zuo)保護(hu)(hu)裝(zhuang)置(zhi)的安裝(zhuang)和運行》標準。漏(lou)電(dian)保護(hu)(hu)器(qi)的分斷時(shi)間，當漏(lou)電(dian)電(dian)流為額定漏(lou)電(dian)電(dian)流時(shi)，其動作(zuo)時(shi)間不應大于0.s。

充(chong)(chong)電(dian)(dian)樁一(yi)般提供(gong)常規充(chong)(chong)電(dian)(dian)和快(kuai)速充(chong)(chong)電(dian)(dian)兩種充(chong)(chong)電(dian)(dian)方式，人們(men)可以使用(yong)特定的充(chong)(chong)電(dian)(dian)卡(ka)在充(chong)(chong)電(dian)(dian)樁提供(gong)的人機交互操作界面上刷卡(ka)使用(yong)，進行相應的充(chong)(chong)電(dian)(dian)方式、充(chong)(chong)電(dian)(dian)時間(jian)、費(fei)(fei)用(yong)數(shu)據打(da)印(yin)等操作，充(chong)(chong)電(dian)(dian)樁顯示屏(ping)能顯示充(chong)(chong)電(dian)(dian)量、費(fei)(fei)用(yong)、充(chong)(chong)電(dian)(dian)時間(jian)等數(shu)據。

配電箱的進出線選用低壓電纜，昭通戶外開閉所電纜的選擇應符合技術要求。生產戶外開閉所例如30kVA、50kVA變(bian)壓(ya)器(qi)(qi)的(de)配電(dian)(dian)箱的(de)進線(xian)使用(yong)(yong)(yong)VV22-35×4電(dian)(dian)纜(lan)(lan)，分路(lu)出線(xian)使用(yong)(yong)(yong)同規格的(de)VLV22-35×4電(dian)(dian)纜(lan)(lan)；80kVA、100kVA變(bian)壓(ya)器(qi)(qi)的(de)配電(dian)(dian)箱的(de)進線(xian)分別使用(yong)(yong)(yong)VV22-50×4、VV22-70×4電(dian)(dian)纜(lan)(lan)，分路(lu)出線(xian)分別使用(yong)(yong)(yong)VLV22-50×4、VLV22-70×4電(dian)(dian)纜(lan)(lan),其電(dian)(dian)纜(lan)(lan)與(yu)銅鋁(lv)接(jie)線(xian)鼻(bi)壓(ya)接(jie)后(hou)再用(yong)(yong)(yong)螺栓與(yu)配電(dian)(dian)箱內接(jie)線(xian)樁頭連接(jie)。
