四川新能源汽車充電站供電電源接入(ru)要求：

在(zai)選擇充電(dian)站電(dian)源(yuan)時，要結合本地配電(dian)網建設和本地大負荷預(yu)測。如大電(dian)力(li)負荷、大高峰負荷預(yu)測、用戶上報裝機(ji)容量、供電(dian)半(ban)徑等。，并綜合選擇供電(dian)點。

1.充電站電源(yuan)接入要求

(1)屬(shu)于二級(ji)(ji)電(dian)(dian)(dian)(dian)力(li)用(yong)(yong)戶的(de)(de)充(chong)電(dian)(dian)(dian)(dian)站(zhan)應(ying)由(you)兩(liang)路中(zhong)(zhong)壓(ya)電(dian)(dian)(dian)(dian)源供電(dian)(dian)(dian)(dian)，應(ying)來自不同的(de)(de)變電(dian)(dian)(dian)(dian)站(zhan)或(huo)同一變電(dian)(dian)(dian)(dian)站(zhan)的(de)(de)不同母線段。每個電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路應(ying)能滿(man)足....電(dian)(dian)(dian)(dian)力(li)負荷的(de)(de)供電(dian)(dian)(dian)(dian)要(yao)求(qiu)。(2)屬(shu)于三級(ji)(ji)電(dian)(dian)(dian)(dian)力(li)用(yong)(yong)戶的(de)(de)kloc-0/由(you)單回路中(zhong)(zhong)壓(ya)電(dian)(dian)(dian)(dian)源供電(dian)(dian)(dian)(dian)。(3)充(chong)電(dian)(dian)(dian)(dian)站(zhan)應(ying)采用(yong)(yong)10kV電(dian)(dian)(dian)(dian)壓(ya)等級(ji)(ji)供電(dian)(dian)(dian)(dian)。(4)交流(liu)充(chong)電(dian)(dian)(dian)(dian)樁應(ying)提(ti)供380伏(fu)或(huo)220伏(fu)電(dian)(dian)(dian)(dian)壓(ya)。

2.充(chong)電(dian)站配電(dian)變(bian)壓器的配置原理

(1)變(bian)壓器(qi)應為節能環保的(de)箱式變(bian)壓器(qi)。(2)當(dang)滿足消防條件時，應優先選用油浸式變(bian)壓器(qi)。(3)單臺變(bian)壓器(qi)的(de)額(e)定容量不應大于160千伏安。(4)變(bian)壓器(qi)的(de)負載率(lv)為80%，此時變(bian)壓器(qi)的(de)運行(xing)效率(lv)較高。 

 3.充電(dian)(dian)站和充電(dian)(dian)樁電(dian)(dian)源導線(xian)的選擇

由于(yu)不同充電(dian)站(zhan)的(de)負載能力不同，電(dian)源導(dao)(dao)線的(de)選擇應基于(yu)充電(dian)站(zhan)的(de)負載。選錯會(hui)導(dao)(dao)致供(gong)電(dian)導(dao)(dao)線截面小，充電(dian)電(dian)流(liu)強度大，導(dao)(dao)線無(wu)法承受其(qi)沖擊，導(dao)(dao)致導(dao)(dao)線過載引發(fa)火災等(deng)事故。
