美國三相墊裝式變壓器概述：

三相充液墊裝式(shi)(shi)變(bian)壓器(qi)(qi)（中(zhong)國(guo)(guo)簡稱美(mei)式(shi)(shi)箱變(bian)，由美(mei)國(guo)(guo)COOPER公司率先打入中(zhong)國(guo)(guo)市場）是將變(bian)壓器(qi)(qi)器(qi)(qi)身、高壓負荷開關、熔斷器(qi)(qi)等元器(qi)(qi)件(jian)一同(tong)放在變(bian)壓器(qi)(qi)油(you)箱內，由于美(mei)國(guo)(guo)單位(wei)用電(dian)(dian)量較大，且不采用高壓計量方式(shi)(shi)，低(di)壓間隔內也不設各種儀表和配電(dian)(dian)斷路器(qi)(qi)安裝方便、靈活。全(quan)(quan)絕緣(yuan)、全(quan)(quan)密封(feng)結(jie)構、安全(quan)(quan)可靠、操作方便、免(mian)維護。適用于商業(ye)中(zhong)心，工業(ye)園(yuan)區(qu)、居民小區(qu)、街(jie)道、機場、碼頭、車站、城市市人口密集區(qu)域。

美(mei)國三相墊裝式變壓器主(zhu)要特點：

過載能力強：允許過載2倍(bei)2個(ge)小時，過載1.6倍(bei)7個(ge)小時，但不(bu)影響墊裝式變壓器壽命。

采用(yong)肘式插頭：可(ke)以十分方(fang)便高壓進線電(dian)(dian)纜的(de)連接，可(ke)帶電(dian)(dian)拔插。

采用(yong)(yong)雙熔斷器(qi)保護(hu)：a、插入(ru)式熔斷器(qi)（BAY-o-NET）為雙敏熔絲（溫度、電流(liu)）保護(hu)箱變二次側(ce)發生的(de)短路故(gu)障；b、后(hou)備限流(liu)保護(hu)熔斷器(qi)（ELSP）保護(hu)箱變內部發生的(de)故(gu)障，用(yong)(yong)于保護(hu)高壓側(ce)。

恒豐友電氣生產的墊裝式變(bian)壓(ya)器(qi)一(yi)般采(cai)用高燃點油（FR3），大大增強安(an)全性(xing)和運行可靠性(xing)。

墊裝(zhuang)式變壓(ya)器分為終端型和(he)環網型，轉換十分方便，提(ti)高了供(gong)電的可靠性。

美(mei)國電網(wang)市場目(mu)前(qian)存在(zai)問(wen)題(ti)：

美國能源(yuan)信息署(EIA)發布最新電網可靠性報告稱：

2013年(nian)(nian)至2020年(nian)(nian)期間，美國電力消費者每年(nian)(nian)平均(jun)經歷至少2小時停電。

2017年和(he)2020年這(zhe)兩年，美(mei)國電(dian)網停(ting)電(dian)次數因極(ji)端天氣、電(dian)廠(chang)狀態不佳等多重不利因素影響出現快速上(shang)漲。

2020年是美國(guo)電(dian)網服務系(xi)統表現(xian)最糟糕(gao)的一年，平均每名美國(guo)電(dian)力消費者在2020年經(jing)歷(li)了8小時以上的停電(dian)。

2021年2月一場冬季(ji)風暴襲擊得克薩斯(si)州，近(jin)500萬(wan)人失去電力供應，電費暴漲(zhang)。

受近年來頻(pin)遭極端天氣等自然災害的影響，大(da)規模(mo)停電(dian)事件(jian)時有發生，充分暴露(lu)了美國的國家電(dian)網的脆弱性，急需(xu)大(da)量(liang)投資(zi)改善提升，可想而(er)知(zhi)，美國現有存(cun)量(liang)配網電(dian)力設備的更新，必(bi)將是(shi)巨大(da)市場(chang)。

美國(guo)電網市場(chang)投資(zi)計劃：

美國(guo)現在也在大力(li)推可再生能(neng)源(yuan)，力(li)爭2035年實(shi)現無(wu)碳發電(dian)(dian)。一(yi)直主打“綠色新(xin)政”的(de)(de)拜登(deng)政府對電(dian)(dian)力(li)領域(yu)表達了重點關(guan)切。拜登(deng)強調了建(jian)設新(xin)能(neng)源(yuan)的(de)(de)電(dian)(dian)網(wang)——他還(huan)計劃用1000億(yi)美元建(jian)設一(yi)個更(geng)(geng)有彈(dan)性的(de)(de)電(dian)(dian)網(wang)，倡議對風力(li)、太陽能(neng)和(he)其(qi)他可再生能(neng)源(yuan)項目的(de)(de)稅項優惠政策延長10年，要求更(geng)(geng)多(duo)電(dian)(dian)力(li)來(lai)自低(di)碳能(neng)源(yuan)，還(huan)真有點搞“電(dian)(dian)力(li)新(xin)基(ji)建(jian)”的(de)(de)樣子。根據美國(guo)土(tu)木工程師協會(American Society of Civil Engineers)的(de)(de)數據，到(dao)下一(yi)個十年結束時，美國(guo)電(dian)(dian)網(wang)將(jiang)面臨3380億(yi)美元（約合人民幣22000億(yi)元）的(de)(de)投(tou)資缺口。

進入美國市場三相墊裝式變壓(ya)器的要求(qiu)：

據恒豐友電氣銷售總監JACK講，進入美國(guo)市場的(de)變(bian)壓(ya)(ya)(ya)器(qi)必須符合 IEEE C57.12.00 /IEEE C57.12.90/IEEE C57.12.28標準(zhun)，具備UL 認(ren)證。當地(di)電業局對墊裝(zhuang)式變(bian)壓(ya)(ya)(ya)器(qi)的(de)要(yao)求(qiu)還有一定差(cha)別，比(bi)如美國(guo)俄(e)亥俄(e)州當地(di)電業局就要(yao)求(qiu)，2500KVA的(de)墊裝(zhuang)式變(bian)壓(ya)(ya)(ya)器(qi)必須單(dan)獨配有接(jie)線(xian)箱，用(yong)于變(bian)壓(ya)(ya)(ya)器(qi)溫度(du)檢測及變(bian)壓(ya)(ya)(ya)器(qi)運行(xing)控制(zhi)。在這里要(yao)提醒大家的(de)是，一定要(yao)落實客戶當地(di)電業局的(de)要(yao)求(qiu)，要(yao)是不合規(gui)定，產品將不允許(xu)投入使(shi)用(yong)。

美(mei)國三相墊裝式變壓器(qi)市場前景：

今天(tian)就讓恒豐(feng)友電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)銷售總監JACK與大家一起分享(xiang)一下(xia)美(mei)國(guo)(guo)(guo)(guo)(guo)三相墊(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)式(shi)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)市場信息(xi)。雖(sui)然美(mei)國(guo)(guo)(guo)(guo)(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)發展較(jiao)早，但電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)不統(tong)一，造成全國(guo)(guo)(guo)(guo)(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)不能(neng)互聯，所以(yi)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)組合應該是世界(jie)上(shang)最多的(de)國(guo)(guo)(guo)(guo)(guo)家。目前市場主流工業(ye)(ye)(ye)、商業(ye)(ye)(ye)配電(dian)(dian)(dian)(dian)(dian)(dian)(dian)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)容(rong)量為2500kva：墊(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)式(shi)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi) 2500kva-13.2/0.416kv（比特幣(bi)挖礦配電(dian)(dian)(dian)(dian)(dian)(dian)(dian)用的(de)比較(jiao)多）墊(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)式(shi)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi) 2500kva-13.8/0.416kv,墊(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)式(shi)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi) 2500kva-24.9/0.416kv,雙(shuang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)墊(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)式(shi)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)2500 KVA-14.4kv/24.9kv-240/415v等主要型號等。隨著美(mei)國(guo)(guo)(guo)(guo)(guo)今年(nian)加強對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)的(de)投資建設，未來十年(nian)美(mei)國(guo)(guo)(guo)(guo)(guo)配電(dian)(dian)(dian)(dian)(dian)(dian)(dian)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)市場規(gui)模(mo)(mo)預(yu)估在(zai)330億美(mei)元的(de)市場規(gui)模(mo)(mo)。由于美(mei)國(guo)(guo)(guo)(guo)(guo)當地變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)企業(ye)(ye)(ye)生(sheng)產(chan)周期(qi)普遍在(zai)4個月，所以(yi)肯定滿足不了未來的(de)增長需(xu)求(qiu)，這必然給(gei)我們電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)行業(ye)(ye)(ye)企業(ye)(ye)(ye)帶(dai)來無限商機(ji)。青(qing)島(dao)恒豐(feng)友電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)工程(cheng)有限公司(si)，自2019年(nian)獲得美(mei)國(guo)(guo)(guo)(guo)(guo)墊(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)式(shi)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)UL認證，并打入(ru)美(mei)國(guo)(guo)(guo)(guo)(guo)墊(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)式(shi)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)市場以(yi)來，已積累大量生(sheng)產(chan)制造經驗，熟知美(mei)國(guo)(guo)(guo)(guo)(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力標(biao)準(ANSI electric standards) 和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子工程(cheng)師協會（Institute of Electrical and Electronics Engineers）及美(mei)國(guo)(guo)(guo)(guo)(guo)當地電(dian)(dian)(dian)(dian)(dian)(dian)(dian)業(ye)(ye)(ye)局要求(qiu)質(zhi)量標(biao)準，生(sheng)產(chan)的(de)三相充油式(shi)墊(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)完全符合美(mei)國(guo)(guo)(guo)(guo)(guo)當地質(zhi)量標(biao)準。

縱觀(guan)全球，美國是世界上除中國之(zhi)后的(de)第(di)二大變壓器(qi)市場(chang)，隨著美國的(de)電力(li)(li)基建投資(zi)計(ji)劃(hua)的(de)實施，未來十年必將是全球電力(li)(li)變壓器(qi)增長(chang)潛力(li)(li)最大的(de)市場(chang)。
