電氣安全主要測試指標包括交/直流耐壓、絕緣電阻、泄漏電流、接地電阻等。交/直流耐壓試驗用于檢驗產(chǎn)品在實際工作狀態(tài)下的電氣安全性能，是檢驗設備電氣安全性能的重要指標之一。 </p> <p> 目前市場上所見的耐壓測試儀采用GB4706（等同IEC1010）標準，使用較多的是臺式結構的單項測試指標測試儀器，不能滿足用戶需要多指標綜合測試的需求；而且目前市場上的耐壓測試儀多采用的是傳統(tǒng)的測試方法，測試精度不高，采用的技術和主要性能指標與國外先進水平有一定的差距，不能完全滿足目前發(fā)展的電氣安全性能測試工作的需要。因此研究符合新國際標準的采用先進技術和具有更好性能指標的耐壓測試系統(tǒng)具有重要意義。 </p><p style="text-indent:25px">耐壓測試的基本原理：把一個高于正常工作的電壓加在被測設備的絕緣體上，并持續(xù)一段規(guī)定的時間，如果其間的絕緣性足夠好，加在上面的電壓就只會產(chǎn)生很小的漏電流。如果一個被測設備絕緣體在規(guī)定的時間內(nèi)，其漏電電流保持在規(guī)定的范圍內(nèi)，就可以確定這個被測設備可以在正常的運行條件下安全運行。進行耐壓測試時，技術規(guī)格不同被測試品，測量標準也就不同。對一般被測設備，耐壓測試是測量火線與機殼之間的漏電流值，基本規(guī)定是：以兩倍于被測物的工作電壓再加1000V作為測試的標準電壓。儀器空載調整高壓時，漏電流指示表頭有起始電流，均屬正常，不影響測試精度。</p><div

全自動電容電橋測試儀是在無功補償裝置**工作組的指導下，針對變電站現(xiàn)場測量電容器的電容值時存在的問題而專門研制的，它著重解決了以下問題： </p> <p> (1) 現(xiàn)場測量電容器需拆除連接線，不僅工作量大而且易損壞電容器； </p> <p> (2) 電容表輸出電壓低而導致故障檢出率低。 </p> <p> 全自動電容電橋測試儀具有測量工作量小、快捷簡便、性能穩(wěn)定、測量準確、故障檢出率高等特點。此外，它的電流測量單元還可兼作CVT、避雷器等電器設備的測量之用，具有一機多能的功效。深圳市展榮新電子有限公司為客戶多方面提供各種電子變壓器生產(chǎn)測試儀器，歡迎您來電咨詢！安微電子變壓器短路阻抗測試儀</p><p
