Features of ZGF-120kV DC High Voltage Generator
1. Small size, light weight, beautiful and reliable, easy to operate, complete functions, easy to use in the field
2. Adopt advanced technology and process manufacturing, apply PWM high-frequency pulse width modulation technology, pulse train logic array modulation, use high-power IGBT devices, use high-frequency technology to increase the frequency, the frequency is up to 100kHz, so that the output high voltage stability is higher. The Bowen coefficient is smaller.
3. The high-frequency DC high-voltage generator has high precision and accurate measurement. Both voltage and current are digitally displayed. The voltage resolution is 0.1kv, and the current resolution is 0.1uA. The voltmeter on the control box directly displays the voltage value added to the load sample. There is no need to add a voltage divider when using it, and the wiring is simple. The instrument has the high and low voltage ends to measure the leakage current, and the high voltage end adopts a circular digital meter to display. It is not afraid of discharge shock, has good anti-interference performance, and is suitable for on-site use.
4. High voltage regulation stability, smooth voltage regulation across the entire range, imported single multi-turn potentiometer for output voltage regulation, stable boost process, high regulation accuracy, and designed with coarse and fine adjustment functions. The voltage regulation is better than 0.1%, the voltage and current measurement error is less than 1.0%, and the pulsation 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 special disconnection protection. The automatic protection circuit has strong functions, complete and reliable protection, and safe operation. Various technical indicators are superior to industry standards and superior to similar products.
6. The high-frequency DC high-voltage generator is added with a high-precision 75%VDC-1mA function, which brings great convenience to the measurement of zinc oxide arresters. No need to calculate with just one click. There is a 75% voltage function key on the control box of this instrument. When doing the zinc oxide test of the lightning arrester, when the current rises to 1000uA, turn on the 0.75 button. At this time, the value displayed by the voltmeter and ammeter is 75% of the data. , Immediately return the boost knob to the zero position after finishing, and at the same time, return the fine voltage knob to the zero position, and immediately press the green button to cut off the high voltage and turn off the power switch. Do other experiments.
7. Convenient over-voltage setting function, adopting digital dial switch, can display the setting voltage value intuitively, making you operate more freely, and the display value unit is kv.
8. The pressure doubler can be divided into sections, used on site, flexible and convenient, multi-purpose in one machine, economical and affordable
