日前，國產電壓等級最高的24萬千伏安、750千伏單相無勵磁調壓發電機變壓器一次性通過全部試驗，這標志著又一臺具有完全自主知識產權的750千伏單相無勵磁調壓發電機變壓器，在西安電力機械制造公司成功誕生。試驗結果顯示這臺新產品不僅具有局放和噪音小、溫升和損耗低等優點，其技術性能達到國際先進水平，而且更令人關注的是：這臺設備和同等類型的進口設備相比，造價可降低20%-25%，成為名副其實的“物美價廉”產品，在大大滿足國內外輸變電設備配套需要的同時，也給受金融危機沖擊略顯低迷的國內外同行業市場帶來了一股清新空氣。
為(wei)了減少線路損耗、延長送電(dian)(dian)(dian)(dian)(dian)距(ju)離、降低建(jian)設(she)和(he)運行(xing)成本，電(dian)(dian)(dian)(dian)(dian)網的輸電(dian)(dian)(dian)(dian)(dian)容量(liang)在不(bu)斷增(zeng)加(jia)。目前，750千(qian)伏(fu)輸電(dian)(dian)(dian)(dian)(dian)已經成為(wei)西(xi)北地區的主流，與之相配的發(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)變(bian)壓(ya)(ya)器(qi)(qi)也(ye)成為(wei)變(bian)壓(ya)(ya)器(qi)(qi)市場(chang)的重要(yao)產(chan)(chan)品(pin)。致(zhi)力于“高、經、尖”技(ji)術(shu)(shu)(shu)的西(xi)電(dian)(dian)(dian)(dian)(dian)集團從二(er)十世紀八十年代(dai)起就開(kai)(kai)始有計劃地開(kai)(kai)展消化吸收引進(jin)(jin)技(ji)術(shu)(shu)(shu)，通過(guo)對國外關(guan)鍵技(ji)術(shu)(shu)(shu)科研(yan)(yan)攻關(guan)的技(ji)術(shu)(shu)(shu)創新(xin)，掌(zhang)握(wo)(wo)了500千(qian)伏(fu)變(bian)壓(ya)(ya)器(qi)(qi)降低損耗、噪音振動和(he)局放的關(guan)鍵技(ji)術(shu)(shu)(shu)，實(shi)現了產(chan)(chan)品(pin)結(jie)構標準(zhun)化，研(yan)(yan)制出(chu)可靠(kao)性高的第二(er)代(dai)、第三(san)代(dai)產(chan)(chan)品(pin)。2005年，西(xi)電(dian)(dian)(dian)(dian)(dian)集團為(wei)我(wo)國首條750千(qian)伏(fu)輸變(bian)電(dian)(dian)(dian)(dian)(dian)工(gong)程(cheng)研(yan)(yan)制成功首批超高壓(ya)(ya)變(bian)壓(ya)(ya)器(qi)(qi)和(he)并聯電(dian)(dian)(dian)(dian)(dian)抗器(qi)(qi)。2008年，西(xi)電(dian)(dian)(dian)(dian)(dian)集團再度(du)為(wei)750千(qian)伏(fu)輸變(bian)電(dian)(dian)(dian)(dian)(dian)二(er)期(qi)工(gong)程(cheng)成功提供了同類(lei)產(chan)(chan)品(pin)。在此(ci)基礎上，西(xi)電(dian)(dian)(dian)(dian)(dian)集團通過(guo)對超高壓(ya)(ya)關(guan)鍵技(ji)術(shu)(shu)(shu)進(jin)(jin)一(yi)步研(yan)(yan)究，在750千(qian)伏(fu)發(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)變(bian)壓(ya)(ya)器(qi)(qi)絕(jue)緣(yuan)結(jie)構、高壓(ya)(ya)出(chu)線結(jie)構設(she)計、油(you)箱(xiang)強(qiang)度(du)和(he)屏(ping)蔽技(ji)術(shu)(shu)(shu)等方面進(jin)(jin)行(xing)大膽創新(xin)，研(yan)(yan)制成功這(zhe)臺技(ji)術(shu)(shu)(shu)含量(liang)更(geng)高而制造成本卻更(geng)低的新(xin)產(chan)(chan)品(pin)。這(zhe)充分(fen)體現了西(xi)電(dian)(dian)(dian)(dian)(dian)集團依靠(kao)自(zi)主創新(xin)，已經完(wan)全掌(zhang)握(wo)(wo)了750千(qian)伏(fu)輸變(bian)電(dian)(dian)(dian)(dian)(dian)設(she)備的設(she)計、制造、安裝、調試(shi)等技(ji)術(shu)(shu)(shu)，完(wan)全具備了駕馭(yu)750千(qian)伏(fu)電(dian)(dian)(dian)(dian)(dian)網建(jian)設(she)的能力。
