產(chǎn)品簡介

南澳電氣NAVLF超低頻高壓發(fā)生器試驗裝置結(jié)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、保護完全自動化，并且在自動升壓過程中能進行人工干預(yù)。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、打印機輸出試驗報告。設(shè)計指標完全符合《電力設(shè)備專用測試儀器通用技術(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?，F(xiàn)在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(shè)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(shè)備的整體功耗較大。均能克服這樣一些不足之處。

南澳電氣NAVLF超低頻高壓發(fā)生器試驗裝置產(chǎn)品別名

超低頻高壓發(fā)生器，NAVLF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,超低頻發(fā)生器

南澳電氣NAVLF超低頻高壓發(fā)生器試驗裝置產(chǎn)品特性

1.電流、電壓數(shù)據(jù)均直接通過高壓側(cè)采樣獲得，所以數(shù)據(jù)真實、準確。

2.過壓保護：當輸出超過所設(shè)定的限壓值時，儀器將停機保護，動作時間小于２０ms。

3.過流保護：設(shè)計為高低壓雙重保護，高壓側(cè)可按設(shè)定值進行停機保護；低壓側(cè)的電流超過額定電流時將進行停機保護，動作時間都小于２０ms。

4.高壓輸出保護電阻設(shè)計在升壓體內(nèi)，所以外面不需另接保護電阻。

5.由于采用了高低壓閉環(huán)負反饋控制電路，所以輸出無容升效應(yīng)。
