四川新能源汽車充電站供電(dian)電(dian)源接(jie)入要(yao)求(qiu)：

在選擇充(chong)電站(zhan)電源(yuan)時(shi)，要結合本地(di)配電網建設和(he)本地(di)大負(fu)荷預測。如(ru)大電力負(fu)荷、大高(gao)峰負(fu)荷預測、用戶上(shang)報裝機容量(liang)、供(gong)電半(ban)徑等。，并(bing)綜合選擇供(gong)電點(dian)。

1.充電站電源接入要求(qiu)

(1)屬(shu)于二級電(dian)(dian)力(li)用(yong)(yong)戶的充(chong)(chong)電(dian)(dian)站(zhan)應(ying)(ying)由(you)兩路中(zhong)壓電(dian)(dian)源供(gong)電(dian)(dian)，應(ying)(ying)來自(zi)不同的變電(dian)(dian)站(zhan)或(huo)同一變電(dian)(dian)站(zhan)的不同母線段。每(mei)個(ge)電(dian)(dian)源電(dian)(dian)路應(ying)(ying)能滿足(zu)....電(dian)(dian)力(li)負(fu)荷的供(gong)電(dian)(dian)要(yao)求。(2)屬(shu)于三級電(dian)(dian)力(li)用(yong)(yong)戶的kloc-0/由(you)單回路中(zhong)壓電(dian)(dian)源供(gong)電(dian)(dian)。(3)充(chong)(chong)電(dian)(dian)站(zhan)應(ying)(ying)采用(yong)(yong)10kV電(dian)(dian)壓等級供(gong)電(dian)(dian)。(4)交(jiao)流充(chong)(chong)電(dian)(dian)樁應(ying)(ying)提供(gong)380伏或(huo)220伏電(dian)(dian)壓。

2.充電站(zhan)配電變壓器的(de)配置原理

(1)變(bian)(bian)壓器(qi)應(ying)為節能環保的(de)(de)(de)箱式變(bian)(bian)壓器(qi)。(2)當滿(man)足消防條件時，應(ying)優先選用油浸式變(bian)(bian)壓器(qi)。(3)單臺變(bian)(bian)壓器(qi)的(de)(de)(de)額定容(rong)量不應(ying)大于160千(qian)伏安(an)。(4)變(bian)(bian)壓器(qi)的(de)(de)(de)負載(zai)率為80%，此時變(bian)(bian)壓器(qi)的(de)(de)(de)運行效率較高(gao)。

3.充(chong)電(dian)站和充(chong)電(dian)樁(zhuang)電(dian)源導線(xian)的(de)選擇

由于不(bu)同充(chong)(chong)電(dian)站(zhan)(zhan)的負載能(neng)力不(bu)同，電(dian)源導(dao)線(xian)(xian)的選擇應基(ji)于充(chong)(chong)電(dian)站(zhan)(zhan)的負載。選錯會導(dao)致供(gong)電(dian)導(dao)線(xian)(xian)截(jie)面(mian)小(xiao)，充(chong)(chong)電(dian)電(dian)流(liu)強度大，導(dao)線(xian)(xian)無法承受(shou)其(qi)沖擊(ji)，導(dao)致導(dao)線(xian)(xian)過載引(yin)發火災等事故。
