11月(yue)29日，冀(ji)北電(dian)科院(yuan)聯合南瑞繼保(bao)電(dian)氣有限公司(si)完成了張北換流(liu)站四臺高(gao)壓直流(liu)斷(duan)路器(qi)小電(dian)流(liu)及額定電(dian)流(liu)分斷(duan)試驗。至此(ci)，500千伏高(gao)壓直流(liu)斷(duan)路器(qi)特(te)殊試驗完成。

500千伏高(gao)壓(ya)直流(liu)斷(duan)路器(qi)(qi)分斷(duan)試(shi)(shi)(shi)驗(yan)是考核(he)斷(duan)路器(qi)(qi)是否滿(man)足投(tou)運要求的重要一環，試(shi)(shi)(shi)驗(yan)過程(cheng)(cheng)涉(she)及斷(duan)路器(qi)(qi)本體各組部件(jian)及二次控保等多個(ge)方面。作為試(shi)(shi)(shi)驗(yan)負責單位，冀北電(dian)科院成(cheng)(cheng)立相關團隊(dui)，聯合南(nan)瑞繼保提前部署，深度參與(yu)斷(duan)路器(qi)(qi)現場調試(shi)(shi)(shi)。完(wan)成(cheng)(cheng)所有聯調項目后，試(shi)(shi)(shi)驗(yan)人員結合前期(qi)出廠(chang)試(shi)(shi)(shi)驗(yan)結果(guo)及現場實際(ji)情況，設(she)計了(le)(le)額(e)(e)定(ding)(ding)電(dian)流(liu)分斷(duan)的試(shi)(shi)(shi)驗(yan)方案，于11月26日(ri)開展了(le)(le)張北柔直工(gong)程(cheng)(cheng)第一臺500千伏高(gao)壓(ya)直流(liu)斷(duan)路器(qi)(qi)額(e)(e)定(ding)(ding)電(dian)流(liu)分斷(duan)試(shi)(shi)(shi)驗(yan)。通(tong)(tong)過試(shi)(shi)(shi)驗(yan)總結和波形分析(xi)，試(shi)(shi)(shi)驗(yan)人員完(wan)成(cheng)(cheng)了(le)(le)進一步的完(wan)善(shan)調試(shi)(shi)(shi)，隨后完(wan)成(cheng)(cheng)了(le)(le)三次小(xiao)電(dian)流(liu)分斷(duan)及三次額(e)(e)定(ding)(ding)電(dian)流(liu)分斷(duan)，試(shi)(shi)(shi)驗(yan)均順利(li)通(tong)(tong)過。

500千伏高壓直(zhi)流(liu)(liu)斷路器(qi)在張北(bei)柔直(zhi)工程中應用，對保(bao)障直(zhi)流(liu)(liu)系統安(an)全(quan)穩定(ding)運行具有重(zhong)要(yao)意義。冀北(bei)電(dian)科院全(quan)程密切跟進高壓直(zhi)流(liu)(liu)斷路器(qi)的(de)設計研(yan)發、制造安(an)裝及現場調試，完成了從無到有的(de)技術(shu)儲(chu)備，保(bao)障了此項試驗成功實施。
