配電箱是數據上的海量參數，訂做戶外開閉所一般是構成低壓林按電氣接線，要求將開關設備、測量儀表、戶外開閉所哪家好保(bao)護電(dian)器和輔(fu)助(zhu)設備(bei)組裝在封(feng)閉或半封(feng)閉金屬柜(ju)中或屏幅上，構(gou)成低壓配(pei)電(dian)箱。正常(chang)運行時可借助(zhu)手動(dong)或自動(dong)開關接通或分(fen)斷電(dian)路。

隨著電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)子技術和(he)(he)變(bian)流(liu)(liu)控制技術的(de)(de)(de)飛速發展(zhan)，高精度(du)可控變(bian)流(liu)(liu)技術的(de)(de)(de)成(cheng)熟(shu)和(he)(he)普(pu)及，分(fen)階段恒(heng)流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)模式(shi)已(yi)經基本被充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)和(he)(he)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)連續變(bian)化的(de)(de)(de)恒(heng)壓(ya)限(xian)流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)模式(shi)取代(dai)。主導充(chong)(chong)電(dian)(dian)(dian)(dian)工(gong)藝的(de)(de)(de)還是恒(heng)壓(ya)限(xian)流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)模式(shi)。接觸式(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)最大問題在于它的(de)(de)(de)安全性和(he)(he)通(tong)用(yong)性。為了使(shi)它滿(man)足(zu)嚴(yan)格的(de)(de)(de)安全充(chong)(chong)電(dian)(dian)(dian)(dian)標準，必須在電(dian)(dian)(dian)(dian)路上采用(yong)許多措施使(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)設(she)備能夠在各種環境下安全充(chong)(chong)電(dian)(dian)(dian)(dian)，恒(heng)壓(ya)限(xian)流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)和(he)(he)分(fen)階段恒(heng)流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)均屬于接觸式(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)技術。新型的(de)(de)(de)電(dian)(dian)(dian)(dian)動汽車感應充(chong)(chong)電(dian)(dian)(dian)(dian)技術發展(zhan)很快。

快速充(chong)(chong)電樁（栓）設備采用(yong)(yong)交(jiao)(jiao)直(zhi)流(liu)一體的(de)結(jie)構。既(ji)可(ke)實現直(zhi)流(liu)充(chong)(chong)電，也可(ke)以交(jiao)(jiao)流(liu)充(chong)(chong)電。白天充(chong)(chong)電業務(wu)多的(de)時候(hou)，使用(yong)(yong)直(zhi)流(liu)方式進行快速充(chong)(chong)電，當夜間充(chong)(chong)電站用(yong)(yong)戶少(shao)時可(ke)用(yong)(yong)交(jiao)(jiao)流(liu)充(chong)(chong)電進行慢充(chong)(chong)操作。

在農網改造中當時(shi)由于需求的配(pei)電(dian)箱(xiang)(xiang)數量(liang)大、施工期(qi)短，配(pei)電(dian)箱(xiang)(xiang)廠(chang)需要有(you)關低壓電(dian)器(qi)的供(gong)貨時(shi)間急且數量(liang)多(duo)，因(yin)而(er)產生(sheng)(sheng)了(le)對產品(pin)質量(liang)的要求不(bu)嚴格的現象，造成了(le)一些產品(pin)投入運行(xing)后不(bu)久就(jiu)發生(sheng)(sheng)故(gu)障。如有(you)些型(xing)號交流接觸器(qi)在配(pei)電(dian)箱(xiang)(xiang)投運后不(bu)久，就(jiu)因(yin)接觸器(qi)合閘線圈燒(shao)壞，而(er)無(wu)法運行(xing)。

充(chong)(chong)電(dian)樁其(qi)功(gong)能類似于加(jia)油(you)站里面的加(jia)油(you)機，可以(yi)固(gu)定在地面或墻壁，安裝于公(gong)共建筑(zhu)（公(gong)共樓宇(yu)、商場(chang)、公(gong)共停車(che)(che)場(chang)等）和(he)居民小區停車(che)(che)場(chang)或充(chong)(chong)電(dian)站內，可以(yi)根據不同(tong)的電(dian)壓(ya)等級為各種型號的電(dian)動汽車(che)(che)充(chong)(chong)電(dian)。充(chong)(chong)電(dian)樁的輸入端(duan)與(yu)交流(liu)電(dian)網直接連接，輸出端(duan)都裝有充(chong)(chong)電(dian)插(cha)頭(tou)用于為電(dian)動汽車(che)(che)充(chong)(chong)電(dian)
