近日，南方電網公司“換流變壓器絕(jue)緣(yuan)質量提升的關(guan)鍵技術研究(jiu)與(yu)工(gong)程應用”通過科技成(cheng)果鑒(jian)定，成(cheng)果總(zong)體技術及工(gong)程應用規模處(chu)于國際先進水平。

換(huan)(huan)(huan)(huan)流(liu)(liu)變(bian)壓(ya)(ya)器(qi)(qi)是(shi)直(zhi)流(liu)(liu)輸電(dian)(dian)系統的(de)(de)核(he)心設備，其絕緣(yuan)(yuan)(yuan)(yuan)(yuan)質(zhi)(zhi)(zhi)量的(de)(de)提升(sheng)是(shi)換(huan)(huan)(huan)(huan)流(liu)(liu)變(bian)壓(ya)(ya)器(qi)(qi)國(guo)產(chan)化的(de)(de)關(guan)鍵。該項目由南方(fang)電(dian)(dian)網(wang)公司(si)牽頭華北(bei)電(dian)(dian)力大學、天(tian)威(wei)保變(bian)共7家單位，歷時9年攻克多個核(he)心技(ji)術難題(ti)，并形成(cheng)4方(fang)面的(de)(de)創新成(cheng)果：一是(shi)研發了(le)(le)(le)(le)(le)基于克爾(er)效(xiao)應的(de)(de)全(quan)電(dian)(dian)壓(ya)(ya)工況(kuang)的(de)(de)油紙絕緣(yuan)(yuan)(yuan)(yuan)(yuan)空間(jian)電(dian)(dian)場非介(jie)入式測(ce)(ce)量技(ji)術和裝置，建(jian)(jian)(jian)成(cheng)了(le)(le)(le)(le)(le)南方(fang)電(dian)(dian)網(wang)絕緣(yuan)(yuan)(yuan)(yuan)(yuan)審核(he)試驗室，突破了(le)(le)(le)(le)(le)換(huan)(huan)(huan)(huan)流(liu)(liu)變(bian)壓(ya)(ya)器(qi)(qi)絕緣(yuan)(yuan)(yuan)(yuan)(yuan)設計缺乏(fa)有效(xiao)實(shi)測(ce)(ce)驗證(zheng)的(de)(de)技(ji)術。二(er)是(shi)開展了(le)(le)(le)(le)(le)6.8萬(wan)組有效(xiao)測(ce)(ce)試，構建(jian)(jian)(jian)了(le)(le)(le)(le)(le)國(guo)產(chan)絕緣(yuan)(yuan)(yuan)(yuan)(yuan)材料(liao)性能(neng)參數大樣本(ben)數據(ju)庫，提出(chu)了(le)(le)(le)(le)(le)換(huan)(huan)(huan)(huan)流(liu)(liu)變(bian)壓(ya)(ya)器(qi)(qi)絕緣(yuan)(yuan)(yuan)(yuan)(yuan)材料(liao)綜合遴選評(ping)價技(ji)術，完成(cheng)了(le)(le)(le)(le)(le)糯扎渡、溪洛渡送電(dian)(dian)廣東特高壓(ya)(ya)直(zhi)流(liu)(liu)工程等181臺換(huan)(huan)(huan)(huan)流(liu)(liu)變(bian)壓(ya)(ya)器(qi)(qi)國(guo)產(chan)絕緣(yuan)(yuan)(yuan)(yuan)(yuan)材料(liao)替(ti)代進(jin)口(kou)的(de)(de)技(ji)術評(ping)估，解決了(le)(le)(le)(le)(le)國(guo)產(chan)材料(liao)“能(neng)否用(yong)、如何用(yong)”的(de)(de)技(ji)術問題(ti)。三是(shi)提出(chu)了(le)(le)(le)(le)(le)換(huan)(huan)(huan)(huan)流(liu)(liu)變(bian)壓(ya)(ya)器(qi)(qi)的(de)(de)選型優化系列(lie)原則。四是(shi)建(jian)(jian)(jian)立了(le)(le)(le)(le)(le)基于絕緣(yuan)(yuan)(yuan)(yuan)(yuan)審核(he)的(de)(de)南方(fang)電(dian)(dian)網(wang)換(huan)(huan)(huan)(huan)流(liu)(liu)變(bian)壓(ya)(ya)器(qi)(qi)品(pin)質(zhi)(zhi)(zhi)控制方(fang)法和標準體系，構建(jian)(jian)(jian)了(le)(le)(le)(le)(le)典型絕緣(yuan)(yuan)(yuan)(yuan)(yuan)故(gu)障案例數據(ju)庫，完成(cheng)了(le)(le)(le)(le)(le)云廣特高壓(ya)(ya)直(zhi)流(liu)(liu)工程以來199臺換(huan)(huan)(huan)(huan)流(liu)(liu)變(bian)壓(ya)(ya)器(qi)(qi)的(de)(de)自(zi)主品(pin)質(zhi)(zhi)(zhi)控制和精細質(zhi)(zhi)(zhi)量判定工作，對世(shi)界首次(ci)特高壓(ya)(ya)換(huan)(huan)(huan)(huan)流(liu)(liu)變(bian)壓(ya)(ya)器(qi)(qi)現場成(cheng)功修復(fu)提供了(le)(le)(le)(le)(le)有力的(de)(de)技(ji)術支持。

目(mu)前，該項目(mu)成果已獲授權發(fa)明專利(li)(li)4項、實用(yong)(yong)新型專利(li)(li)7項，參編國(guo)際/國(guo)家(jia)/行業/企業標準12項，發(fa)表論文(wen)20篇(pian)；成果已應用(yong)(yong)于(yu)云廣、兩渡、金中等8項直(zhi)流工(gong)程的主設備選型、國(guo)產化(hua)研制及自主化(hua)品控，經濟和社會(hui)效(xiao)益良好。
