產(chǎn)品簡(jiǎn)介

NAVLF超低頻高壓發(fā)生器試驗(yàn)裝置結(jié)合了現(xiàn)代數(shù)字變頻先進(jìn)技術(shù)，采用微機(jī)控制，升壓、降壓、測(cè)量、保護(hù)完全自動(dòng)化，并且在自動(dòng)升壓過(guò)程中能進(jìn)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(jī)輸出試驗(yàn)報(bào)告。設(shè)計(jì)指標(biāo)完全符合《電力設(shè)備專用測(cè)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(biāo)準(zhǔn)，使用十分方便?，F(xiàn)在國(guó)內(nèi)外均采用機(jī)械式的辦法進(jìn)行調(diào)制和解調(diào)產(chǎn)生超低頻信號(hào)，所以存在正弦波波形不標(biāo)準(zhǔn)，測(cè)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(jìn)行放電整形，所以設(shè)備的整體功耗較大。NAVLF超低頻高壓發(fā)生器均能克服這樣一些不足之處。

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(yàn)裝置、超低頻耐壓試驗(yàn)裝置,超低頻發(fā)生器

產(chǎn)品特性

1.電流、電壓數(shù)據(jù)均直接通過(guò)高壓側(cè)采樣獲得，所以數(shù)據(jù)真實(shí)、準(zhǔn)確。

2.過(guò)壓保護(hù)：當(dāng)輸出超過(guò)所設(shè)定的限壓值時(shí)，儀器將停機(jī)保護(hù)，動(dòng)作時(shí)間小于20ms。

3.過(guò)流保護(hù)：設(shè)計(jì)為高低壓雙重保護(hù)，高壓側(cè)可按設(shè)定值進(jìn)行停機(jī)保護(hù)；低壓側(cè)的電流超過(guò)額定電流時(shí)將進(jìn)行停機(jī)保護(hù)，動(dòng)作時(shí)間都小于20ms。

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

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