3月21日，隨(sui)著3臺20千(qian)伏(fu)/400伏(fu)配變投(tou)入(ru)運行(xing)，江蘇(su)南京雨花(hua)經濟開發區第一條10千(qian)伏(fu)升壓20千(qian)伏(fu)線(xian)路——龍飛線(xian)成功投(tou)運，為附(fu)近200戶居民和十(shi)九冶金廠提供了更加穩定的電(dian)力供應。
龍飛線首次采用(yong)10千(qian)(qian)伏(fu)(fu)/20千(qian)(qian)伏(fu)(fu)升(sheng)(sheng)壓變，將110千(qian)(qian)伏(fu)(fu)古雄變送出線的(de)電壓升(sheng)(sheng)壓至20千(qian)(qian)伏(fu)(fu)，借用(yong)原有10千(qian)(qian)伏(fu)(fu)線路(lu)輸送。升(sheng)(sheng)壓線路(lu)電纜長度800米，架空線長686米。
2007年(nian)，江(jiang)蘇省電(dian)(dian)(dian)(dian)力公司已(yi)全面(mian)推廣(guang)20千(qian)伏電(dian)(dian)(dian)(dian)壓等級供(gong)電(dian)(dian)(dian)(dian)。由于城市配電(dian)(dian)(dian)(dian)網(wang)絡中電(dian)(dian)(dian)(dian)纜架空線(xian)混合型電(dian)(dian)(dian)(dian)壓線(xian)路(lu)使用較廣(guang)，此次線(xian)路(lu)升壓的成(cheng)功(gong)送(song)電(dian)(dian)(dian)(dian)，為江(jiang)蘇電(dian)(dian)(dian)(dian)壓混合型線(xian)路(lu)升壓20千(qian)伏運行科技項目研(yan)究(jiu)積累了寶(bao)貴經(jing)驗(yan)。升壓送(song)電(dian)(dian)(dian)(dian)成(cheng)功(gong)后，南京供(gong)電(dian)(dian)(dian)(dian)公司運行人員全面(mian)加強夜巡、特巡和紅外測溫，密切關注線(xian)路(lu)長期運行效果。
據(ju)了解，南京雨花經濟(ji)開(kai)發區內的110千伏(fu)/20千伏(fu)龍(long)鳳變，將于2008年迎峰(feng)度夏前投(tou)運。屆時，該地區將全面(mian)推廣20千伏(fu)電(dian)(dian)壓等(deng)級供(gong)電(dian)(dian)。
