電壓互感器自身出現故障的處理

發布日期：2022-04-18 點擊率：62

     1、異常處理

    （1）立即將有關情況匯報所屬調度和有關領導，并申請停電處理。

    （2）220kV電壓互感器出現一般性故障，可用刀閘隔離，故障嚴重時，嚴禁用刀閘隔離，只能通過母聯開關來切斷電源。

    （3）500kV電壓互感器故障要停用時，相應的母線或線路必須停用。

    2、異常現象

    （1）本體有過熱現象。

    （2）內部有放電聲和不正常的噪聲。

    （3）油面上升并出現碳質，裝備金屬膨脹器的220kV電壓互感器，監視窗內的紅線位置過高。

    （4）有滲漏油現象。
