class="title">詳細說明</p><div id="fiopgwm" class="box"><p><p style="text-indent:25px">過去在進行電纜耐壓試驗時都采用直流耐壓試驗。在1980年左右，國外電力部門發(fā)現(xiàn)直流耐壓試驗對橡塑絕緣是無效的且具有危害性。我國在九十年代開始研究和實踐交流耐壓試驗技術(shù)。經(jīng)過20多年的研究和實踐，世界各國紛紛采用交流耐壓試驗代替直流耐壓試驗。國內(nèi)外有關(guān)標準機構(gòu)也對于高壓電纜的試驗方法作出了更改和修訂。1997年CIGRI國際大電網(wǎng)工作會議對目前采用的直流耐壓試驗方法提出疑議，廣州變壓器試驗，廣州變壓器試驗，并推薦使用工頻及近似工頻（30-300HZ）的交流試驗方法，在全世界范圍內(nèi)推廣應(yīng)用，廣州變壓器試驗。我國很多省份電網(wǎng)已先后頒發(fā)《試驗規(guī)程》，強制規(guī)定用交流耐壓試驗代替直流耐壓試驗。在我國電網(wǎng)相對發(fā)達的省份，交流耐壓試驗已經(jīng)成為強制性標準。其它地區(qū)的試驗規(guī)程也在起草和醞釀中。交流耐壓試驗取代傳統(tǒng)直流耐壓試驗已是大勢所趨。變壓器空載負載測試儀是專門用于在低電壓、小電流情況下測試標準配電電力變壓器容量的儀器。廣州變壓器試驗</p><div

style="text-indent:25px">激磁阻抗參數(shù)與鐵心飽和程度有關(guān)，即與電源電壓大小有關(guān)，試驗電壓必須取額定電壓。空載電流數(shù)值較小，為減小測量誤差，須將電流表靠近變壓器接，然后依次接功率表和電壓表。根據(jù)測量數(shù)據(jù):U2N(低壓側(cè)額定電壓)、U10(高壓側(cè)開路電壓)、I0(低壓側(cè)空載電流)和P0(空載損耗)，按空載運行時的等效電路圖忽略低壓繞組漏阻抗(zm>>z2)，變比k和激磁阻抗參數(shù)?？蛰d試驗在低壓側(cè)加電源，所測數(shù)據(jù)為低壓側(cè)值，求得磁阻抗參數(shù)也為低壓側(cè)值，如需高壓側(cè)的激磁阻抗數(shù)值，還須進行折算，即乘(k*k)。特別注意：對三相變壓器進行參數(shù)計算，應(yīng)首先將測量數(shù)據(jù)換算為相值(相電壓、相電流和一相的損耗)，然后才能代入公式，即公式中所有數(shù)據(jù)必須是相值。</p><p style="text-indent:25px">我國電力系統(tǒng)實行兩部制電價：除了收取計量裝置所計量的費用外，還要根據(jù)變壓器容量收取基本電費；對于較大用戶在投運變壓器時還要一次**納增容費。隨著電力行業(yè)的發(fā)展，用電量的增大，自有變壓器和私人承包變壓器已漸漸占據(jù)了配變中相當?shù)姆蓊~，隨之而來的就是個人為了達到少交費、多用電的目的而采取的各種弄虛作假的手段（主要是改、換變壓器銘牌）；電力部門苦于沒有有效的監(jiān)管手段，有些用戶年偷電費額達數(shù)十萬之多。所以針對這樣的問題也就推動了設(shè)計新型的變壓器測試儀器。如何能夠確保自己購買的變壓器直流電阻測試儀發(fā)揮出它原有的檢測性能，才能夠凸顯出它的高價值。</p><div
