四川新能源汽車充電站供電(dian)電(dian)源接入要(yao)求：

四川(chuan)新能源汽車充電(dian)站

在選擇(ze)充電(dian)站(zhan)電(dian)源時(shi)，要(yao)結合本地(di)配電(dian)網(wang)建(jian)設和本地(di)大(da)負(fu)荷猜(cai)測。如大(da)電(dian)力負(fu)荷、大(da)高峰負(fu)荷猜(cai)測、用戶上(shang)報(bao)裝機容量(liang)、供(gong)電(dian)半徑等。，并綜合選擇(ze)供(gong)電(dian)點。

1.充電站電源接入要求

(1)屬于二級電(dian)(dian)(dian)(dian)力(li)用(yong)戶(hu)(hu)的(de)充(chong)電(dian)(dian)(dian)(dian)站應(ying)由兩路中(zhong)(zhong)壓(ya)(ya)電(dian)(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)(dian)，應(ying)來自(zi)不(bu)同的(de)變電(dian)(dian)(dian)(dian)站或(huo)統一變電(dian)(dian)(dian)(dian)站的(de)不(bu)同母線段。每個電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路應(ying)能知足....電(dian)(dian)(dian)(dian)力(li)負荷的(de)供(gong)電(dian)(dian)(dian)(dian)要(yao)求。(2)屬于三級電(dian)(dian)(dian)(dian)力(li)用(yong)戶(hu)(hu)的(de)kloc-0/由單回(hui)路中(zhong)(zhong)壓(ya)(ya)電(dian)(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)(dian)。(3)充(chong)電(dian)(dian)(dian)(dian)站應(ying)采用(yong)10kV電(dian)(dian)(dian)(dian)壓(ya)(ya)等級供(gong)電(dian)(dian)(dian)(dian)。(4)交(jiao)流充(chong)電(dian)(dian)(dian)(dian)樁應(ying)提供(gong)380伏或(huo)220伏電(dian)(dian)(dian)(dian)壓(ya)(ya)。

2.充電站配電變壓器的配置(zhi)原理(li)

(1)變(bian)(bian)壓器(qi)應為節能環保的箱式(shi)變(bian)(bian)壓器(qi)。(2)當知(zhi)足消防前(qian)提時(shi)，應優先選用油浸式(shi)變(bian)(bian)壓器(qi)。(3)單臺變(bian)(bian)壓器(qi)的額(e)定容量不應大于(yu)160千伏安。(4)變(bian)(bian)壓器(qi)的負載率(lv)為80%，此(ci)時(shi)變(bian)(bian)壓器(qi)的運行效率(lv)較(jiao)高。

3.充電站和充電樁電源導線的選擇

因為不同(tong)充(chong)電站的(de)負載能力不同(tong)，電源導(dao)線(xian)(xian)的(de)選(xuan)擇應基(ji)于充(chong)電站的(de)負載。選(xuan)錯會(hui)導(dao)致供(gong)電導(dao)線(xian)(xian)截面(mian)小，充(chong)電電流強(qiang)度大，導(dao)線(xian)(xian)無法承(cheng)受(shou)其沖擊，導(dao)致導(dao)線(xian)(xian)過載引發火災(zai)等事故。
