        維護

        對真空斷路器應(yīng)該每年進行一次停電檢查維護,以保證正常運行。檢查應(yīng)做好如下方面的工作:
        a)對管子進行斷口工頻耐壓試驗,測試真空度并記錄在冊。
        b)對絕緣件進行工頻耐壓試驗。
        c)測試斷路器的開距、接觸行程和機械特性,并記錄在冊。
        d)對各連接件的可調(diào)整處的連接螺栓、螺母等應(yīng)檢查是否有松動,特別是輔助開關(guān)拐臂處的連接小螺釘,真空管動導(dǎo)電桿連接的鎖緊螺母等。
        e)對各轉(zhuǎn)動關(guān)節(jié)處應(yīng)檢查各種卡簧,銷子等是否松脫;并對各轉(zhuǎn)動、滑動部分加潤滑油膏。
        f)對使用在電流大于1 600 A以上的真空斷路器,應(yīng)對每極作直流電阻測試并記錄在冊。
        g)如需更換管子應(yīng)按產(chǎn)品說明書的要求進行,更換后應(yīng)進行機械特性的測試和耐壓試驗。
        h)年檢后和投運前應(yīng)連續(xù)空載操作8~10次,一切正常方可投運。[3]
