電纜線路的電壓、負荷監(jiān)測注意事項

發(fā)布日期:2022-04-18 點擊率:69

日常對電纜線路的電壓、負荷進行監(jiān)測通常應(yīng)注意以下問題:

    (1)線路電壓。電纜線路的正常工作電壓通常不要超過其額定電壓的15%。對于需要電纜線路作升壓運行的情況,則必須經(jīng)主管領(lǐng)導(dǎo)批準且試驗鑒定后才可進行。

    (2)線路負荷電流。電纜線路負荷電流不要超過長期允許載流量。日常運行中應(yīng)經(jīng)常對負荷的電流進行監(jiān)測,一旦發(fā)現(xiàn)過負荷應(yīng)及時進行處理,以確保電纜不過荷運行。

    (3)線路過載量及允許時間。電纜線路出現(xiàn)故障時允許的過載量及時間如表所示。
