font-size:14px">接合了現(xiàn)代數(shù)字變頻*技術(shù)，采用微機控制，升壓、降壓、測量、保護*自動化。由于全電子化，所以體積小重量輕、大屏幕液晶顯示，清晰直觀、且能顯示輸出波形、打印試驗報告。設計指標*符合《電力設備測試儀器通用技術(shù)條件，第4部分：超低頻高壓發(fā)生器通用技術(shù)條件》電力行業(yè)標準，使用十分方便。現(xiàn)在國內(nèi)外均采用機械式的辦法進行調(diào)制和解調(diào)產(chǎn)生超低頻信號，所以存在正弦波波形不標準，測量誤差大，高壓部分有火花放電，設備笨重，而且正弦波的二，四象限還需要大功率高壓電阻進行放電整形，所以設備的整體功耗較大。</span></p><p><strong>50KV程控超低頻高壓發(fā)生器</strong>產(chǎn)品別稱</p><p><span style="color:rgb(0, 0, 0)">超低頻高壓發(fā)生器、0.1Hz超低頻高壓發(fā)生器、程控超低頻高壓發(fā)生器、超低頻交流高壓試驗裝置、超低頻耐壓試驗裝置、0.1Hz超低頻耐壓測試儀、0.1Hz超低頻電纜耐壓測試儀、0.1Hz超低頻發(fā)電機耐壓測試儀、0.1Hz超低頻電動機耐壓測試儀、0.1Hz絕緣耐壓測試儀、超低頻交流耐壓試驗儀</span></p><p>產(chǎn)品特征</p><p><span style="font-size:14px">1、額定電壓小于或等于50kV的超低頻采用單聯(lián)結(jié)構(gòu)（一臺升壓器）；大于50kV的超低頻采用串聯(lián)結(jié)構(gòu)（兩臺升壓器串聯(lián)），使整體重量大大減輕，帶載能力增強，而且兩臺升壓器可單獨作低電壓等級的超低頻使用。</span></p><p><span style="font-size:14px">2、電流、電壓、波形數(shù)據(jù)均直接從高壓側(cè)采樣獲得，所以數(shù)據(jù)準確。</span></p><p><span style="font-size:14px">3、具有過壓保護功能，當輸出超過所設定的限壓值時，儀器將停機保護，動作時間小于20ms。</span></p><p><span
