【Detailed Description】
Features of ZGF-120kV/2mA high-frequency DC high voltage generator
1. Small size, light weight, more beautiful, more reliable, easy operation, complete functions, suitable for field use, it is an ideal reliable product in the new century.
2. Adopting advanced technology and manufacturing processes, it takes the lead in applying new PWM high-frequency pulse width modulation technology and pulse train logic array modulation, using high-power IGBT devices, and utilizing high-frequency technology to increase frequency up to 100kHz, thereby making the output high voltage more stable and the ripple coefficient smaller.
3. High-frequency DC high voltage generator has high precision and accurate measurement. Both voltage and current are digitally displayed, with voltage resolution of 0.1kV and current resolution of 0.1uA. The voltmeter on the control box directly displays the voltage value applied to the load test object, so no external voltage divider is needed, and wiring is simple. The instrument has leakage current measurement at both high and low voltage ends. The high voltage end uses a circular digital meter display, which is not afraid of discharge impact, has good anti-interference performance, and is suitable for on-site use.
4. High voltage regulation stability, smooth voltage regulation across the full range. The output voltage adjustment adopts an imported single multi-turn potentiometer, with a smooth boosting process and high adjustment precision, and is designed with coarse and fine adjustment functions. Voltage regulation is better than 0.1%, voltage and current measurement error is less than 1.0%, and ripple factor is better than 0.5%.
5. Negative polarity output, zero start, continuously adjustable, with various protection functions such as overvoltage, overcurrent, zero return, grounding protection, and unique disconnection protection. The automatic protection circuit has strong functions, complete and reliable protection, making operation safe, and all technical indicators are superior to industry standards and similar products.
6. High-frequency DC high voltage generator adds a high-precision 75% VDC-1mA function, bringing great convenience to zinc oxide arrester measurement. A simple press is all it takes, no calculation needed. The control box of this instrument has a 75% voltage function key. When doing zinc oxide arrester tests, when the current rises to 1000uA, press the 0.75 button. At this time, the values displayed on the voltmeter and ammeter are the 75% data. After completion, immediately return the boosting knob to zero, and also return the fine voltage adjustment knob to zero, and immediately press the green button to cut off the high voltage and turn off the power switch. Then proceed with other tests.
7. Convenient overvoltage setting function, using digital dial switches, which can visually display the set voltage value, making operation more flexible, with the display unit in kV.
8. The voltage doubling cylinder has a sectional structure, flexible and convenient for field use, one machine for multiple uses, economical and practical
