在農網改造中當時由于需求的配電箱數量大、施工期短，配電箱廠需要有關低壓電器的供貨時間急且數量多，充電樁哪家好因而產生了對產品質量的要求不嚴格的現象，訂做充電樁造成了一些產品投入運(yun)(yun)行后不久(jiu)就發生故障。如有(you)些型號交流接(jie)觸(chu)(chu)器(qi)在配(pei)電箱投運(yun)(yun)后不久(jiu)，就因接(jie)觸(chu)(chu)器(qi)合閘(zha)線圈(quan)燒壞，而(er)無法運(yun)(yun)行。

1.主母(mu)線(xian)最大(da)額(e)定電(dian)(dian)(dian)(dian)(dian)流(liu):主母(mu)線(xian)最大(da)能(neng)夠(gou)承(cheng)載的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)(de)額(e)定值。2.額(e)定短時耐(nai)受(shou)(shou)(shou)電(dian)(dian)(dian)(dian)(dian)流(liu):由(you)生產(chan)廠家(jia)(jia)給(gei)出的(de)(de)(de)(de)(de),成套(tao)設備中某條電(dian)(dian)(dian)(dian)(dian)路在國(guo)家(jia)(jia)標(biao)準GB7251.1-2005中8.2.3規定的(de)(de)(de)(de)(de)試(shi)驗條件(jian)下能(neng)安全承(cheng)載的(de)(de)(de)(de)(de)短時耐(nai)受(shou)(shou)(shou)電(dian)(dian)(dian)(dian)(dian)流(liu)方(fang)(fang)均根值。3.峰值短時耐(nai)受(shou)(shou)(shou)電(dian)(dian)(dian)(dian)(dian)流(liu):在規定試(shi)驗條件(jian)下,生產(chan)廠家(jia)(jia)規定此電(dian)(dian)(dian)(dian)(dian)路能(neng)夠(gou)圓滿地承(cheng)受(shou)(shou)(shou)的(de)(de)(de)(de)(de)峰值電(dian)(dian)(dian)(dian)(dian)流(liu)。4.外殼防護(hu)等級(ji):IEC60529-1989標(biao)準由(you)成套(tao)設備提供的(de)(de)(de)(de)(de)防止(zhi)觸及帶電(dian)(dian)(dian)(dian)(dian)部件(jian),以及外來固體的(de)(de)(de)(de)(de)侵(qin)入和液體的(de)(de)(de)(de)(de)進(jin)入的(de)(de)(de)(de)(de)等級(ji)。具(ju)體等級(ji)劃分詳見IEC60529標(biao)準。5.內部分隔方(fang)(fang)式:根據IEC60529-1989標(biao)準,為(wei)保護(hu)人身安全,將開關柜(ju)獨立(li)劃分成幾個隔室的(de)(de)(de)(de)(de)不(bu)同方(fang)(fang)式。不(bu)同型號的(de)(de)(de)(de)(de)配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju)之間的(de)(de)(de)(de)(de)技(ji)術(shu)參(can)數都(dou)(dou)有很大(da)不(bu)同,而進(jin)口配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju)的(de)(de)(de)(de)(de)技(ji)術(shu)參(can)數基本都(dou)(dou)優(you)于國(guo)產(chan)配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju),但并不(bu)能(neng)認為(wei)進(jin)口配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju)就(jiu)一定比(bi)國(guo)產(chan)配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju)好。

由于(yu)(yu)電(dian)(dian)動汽(qi)車每天(tian)需要(yao)補充(chong)(chong)(chong)(chong)(chong)大(da)量(liang)(liang)電(dian)(dian)能(neng)，經營充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)站就可(ke)以(yi)獲(huo)得巨(ju)大(da)的(de)(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)服(fu)務(wu)收益。相對(dui)于(yu)(yu)加(jia)油站，電(dian)(dian)能(neng)比(bi)較(jiao)安全和(he)方(fang)便，可(ke)在(zai)各地(di)大(da)量(liang)(liang)安裝設(she)置充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)站。根(gen)據(ju)投(tou)資(zi)規模，小到(dao)社(she)區慢速(su)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)樁(zhuang)，大(da)到(dao)公路快速(su)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)站，單(dan)站經營，組網經營均可(ke)。對(dui)于(yu)(yu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)站市(shi)(shi)場(chang)的(de)(de)開放，國家(jia)電(dian)(dian)網以(yi)后可(ke)能(neng)更多地(di)會偏向服(fu)務(wu)和(he)電(dian)(dian)力供應，讓充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)站建設(she)更充(chong)(chong)(chong)(chong)(chong)分地(di)與市(shi)(shi)場(chang)融合，大(da)家(jia)都將是同一個市(shi)(shi)場(chang)的(de)(de)競爭者。因(yin)此提前準(zhun)備、提前規劃，對(dui)從(cong)事電(dian)(dian)池生產(chan)的(de)(de)企業來(lai)說很重要(yao)。充(chong)(chong)(chong)(chong)(chong)換電(dian)(dian)市(shi)(shi)場(chang)，政策有傾(qing)斜，市(shi)(shi)場(chang)有潛力，投(tou)資(zi)又少，將面臨(lin)較(jiao)大(da)的(de)(de)商(shang)機。

控制柜是按電(dian)(dian)(dian)氣接線要求將開關(guan)設(she)備(bei)(bei)、測量(liang)儀表、保(bao)護(hu)電(dian)(dian)(dian)器(qi)和輔(fu)助(zhu)(zhu)設(she)備(bei)(bei)組裝(zhuang)在封閉(bi)或半封閉(bi)金(jin)屬柜中或屏幅(fu)上，其布(bu)置應滿(man)足電(dian)(dian)(dian)力系統正(zheng)常(chang)運(yun)行(xing)的要求，便于檢修，不危及人(ren)身及周圍設(she)備(bei)(bei)的安全。正(zheng)常(chang)運(yun)行(xing)時可借助(zhu)(zhu)手動(dong)(dong)或自(zi)動(dong)(dong)開關(guan)接通或分斷電(dian)(dian)(dian)路。故障或不正(zheng)常(chang)運(yun)行(xing)時借助(zhu)(zhu)保(bao)護(hu)電(dian)(dian)(dian)器(qi)切斷電(dian)(dian)(dian)路或報警。借測量(liang)儀表可顯示運(yun)行(xing)中的各種(zhong)參數，還可對(dui)(dui)某(mou)些電(dian)(dian)(dian)氣參數進(jin)行(xing)調整(zheng)，對(dui)(dui)偏離(li)正(zheng)常(chang)工作狀態進(jin)行(xing)提示或發出信號。常(chang)用于各發、配(pei)、變電(dian)(dian)(dian)所中。
