style="text-indent:25px">對于變壓器絕緣在線檢測zui有效的方法之一是監(jiān)測局部放電電脈沖參量。變壓器正常運行中局部放電量較小,近年生產的110kV以上變壓器局部放電量都控制在500pC以下;但在實際運行中,即使出現有5000pC左右的放電也照常運行,其絕緣缺陷發(fā)展過程可能延續(xù)幾周甚至幾年。在線測量時,由于受現場干擾信號的影響,直接測量局部放電高頻參量較為困難,且對運行設備在進行在線監(jiān)測采集所需信號時應盡量不改變原設備的運行接線狀態(tài)。因此,將信號取樣點選擇在變壓器鐵芯接地引出線和中性點引出線以及高壓套管末屏引出線處,是非常有效及合理的。在任何情況下它不會影響變壓器的正常運行。但傳感器選在鐵芯接地點時,對傳感器和放大器的靈敏度要求比選在套管末屏取樣要求更高。安微變壓器故障檢測儀</p><p
