NAVLF Ultra-low Frequency High Voltage Generator 南澳電氣NAVLF超低頻高壓發生器試驗裝置產品簡介南澳電氣NAVLF超低頻高壓發生器試驗裝置結合了現代數字變頻先進技術，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。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。設計指標完全符合《電力設備專用測試儀器通用技術條件，第4部分：超低頻高壓發生器通用技術條件》電力行業標準，使用十分方便。現在國內外均采用機械式的辦法進行調制和解調產生超低頻信號，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。均能克服這樣一些不足之處。南澳電氣NAVLF超低頻高壓發生器試驗裝置產品別名超低頻高壓發生器，NAVLF超低頻高壓發生器，程控超低頻高壓發生器，超低頻交流高壓試驗裝置，超低頻耐壓試驗裝置,超低頻發生器南澳電氣NAVLF超低頻高壓發生器試驗裝置產品特性 1.電流、電壓數據均直接通過高壓側采樣獲得，所以數據真實、準確。 2.過壓保護：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。 3.過流保護：設計為高低壓雙重保護，高壓側可按設定值進行精確停機保護；低壓側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計在升壓體內，所以外面不需另接保護電阻。 5.由于采用了高低壓閉環負反饋控制電路，所以輸出無容升效應。南澳電氣NAVLF超低頻高壓發生器試驗裝置產品參數 1、輸出額定電壓：略 2、輸出頻率：0.1Hz、0.05Hz、0.02Hz。 3、帶載能力：參見下表 0.1 Hz 最大1.1μF(理論值，現場電纜長度為1－3公里） 0.05 Hz 最大2.2μF(理論值，現場電纜長度為1－3公里） 0.02 Hz 最大5.5μF(理論值，現場電纜長度為1－3公里） 4、測量精度：滿量程的３% 5、電壓正，負峰值誤差：≤３% 6、電壓波形失真度：≤５％ 7、使用條件：戶內、戶外；溫度：-10℃∽+40℃；濕度：≤85％RH 8、電源：交流50 Hz，220V ±5% 南澳電氣NAVLF超低頻高壓發生器試驗裝置注意事項 1、NAVLF超低頻高壓發生器所配升壓器不得作它用。 2、機內帶電,切勿自行拆機修理，以免發生意外。儀器有故障，應與南澳電氣聯系修理。 3、關機后應用放電棒對試品進行充分放電,再拆線。 4、開機前應用放電棒對試品進行充分放電。 5、每次啟動升壓前應用放電棒對試品進行充分放電。 Product introduction NAVLF Ultra-low Frequency High Voltage Generator combines the modern digital frequency advanced technology, uses computer control, boost, buck and measurement, automatically full protection, and in the process can automatically boost can carry a manual intervention in the process of automatically boosting. Since all with electronic, is small and light, large-screen LCD displayed, clear and intuitive, printer out testing report. The Design indicators is in full compliance "special test equipment electrical equipment General technical conditions, Part 4: ultra-low frequency high voltage generator general technical conditions" power industry standard, easy to use. Nowadays home and abroad adopted mechanical approach to produce NAVLF modulation and demodulation to generate signal, so there is no standard sine waveform, and measurement error is large, high-voltage part with a spark discharge, heavy equipment, and the two and four-quadrants of sine wave, need large power high voltage resistance to discharge and sharp, the total total power consumption is very large. The NAVLF Ultra-low Frequency High Voltage Generator can overcome these shortcomings. Also called name NAVLF high voltage generator, NAVLF high voltage generator, programmable NAVLF frequency high voltage generator, NAVLF frequency AC high voltage testing equipment, NAVLF frequency withstand testing equipment, NAVLF frequency generator. The Characteristics of the products 1, Advanced technology: Using digital frequency conversion technology, microcomputer controlled, boost, buck, measurement, protection and full automated testing process 2, Easy to operate: Wiring is simple, easy to move and operation 3, Comprehensive protection : Multiple protection (overload protection, high and low voltage over current protection), prompt action (action time ≤ 20ms), is a safe and reliable instrument 4, Safe and reliable: the controller and high-voltage generator voltage connection via low voltage, photoelectric control, safety and reliability. 5, Using a high-pressure closed-loop negative feedback control circuit, the output capacity without capacity boost effect 6, Fully equipped: large LCD display, automatic storage, automatic printing 7, Large test range: 0.1Hz, 0.05Hz and 0.02Hz multi-frequency selection, large testing range 8, Small in size, light in weight: is conducive to outdoor work The parameters of the products 1, The output voltage: see table below 2, The output frequency: 0.1Hz, 0.05Hz, 0.01Hz. 3, Load capacity: see table 0.1 Hz Maximum 1.1μF (theoretical value, on-site cable length 1-3 km) 0.05 Hz Maximum 2.2μF (theoretical value, on-site cable length 1-3 km) 0.02 Hz Maximum 5.5μF (theoretical value, on-site cable length 1-3 km) 4, Accuracy: 3% of full scale 5, The voltage positive and negative peak error: ≤ 3% of full scale 6, The voltage waveform distortion: ≤ 5% 7,Usage conditions : indoor, outdoor; Temperature: -10 ℃ ∽ +40 ℃; Humidity: ≤ 85% RH 8,Power Supply: AC 50 Hz, 220V ± 5% Attention should take 1, NAVLF Ultra-low Frequency High Voltage Generator are equipped with a booster, can not use for other ways. 2, If the machine charged, do not try to disassemble and repair, to avoid accidents. If the 3,After shut up the instrument, please use discharging rod to discharge the tested object fully, then dismantle the wire. 4, Before turn on the instrument, please use the discharging rod to discharge the tested object fully. 5, Before turn on and boost, please use the discharging rod to discharge the tested object fully.
