【KDZG-IV Introduction to Intelligent DC High Voltage Generator】
KDZG-IV Intelligent DC High Voltage Generator adopts a large-screen LCD display, intelligent printing, and is the first to have intelligent poor grounding protection and alarm functions, ensuring high safety and fast response. It is suitable for DC high voltage testing of zinc oxide arresters, magnetic blow arresters, power cables, generators, transformers, switches, and other equipment in power departments, factory and mining enterprise power departments, scientific research units, railways, chemical industry, power plants, etc.
【KDZG-IV Features of Intelligent DC High Voltage Generator】
1. Smaller size, lighter weight, more beautiful, more reliable, easy to operate, complete functions, suitable for field use, it is an ideal reliable product in the new century.
2. Adopting advanced technology and manufacturing processes, it is the first to apply PUM intelligent pulse width modulation technology and pulse train logic array modulation, using high-power IGBT devices, and utilizing intelligent technology to improve efficiency with a frequency up to 40kHz, resulting in higher output high voltage stability and smaller ripple coefficient.
3. Using computer control technology, the large-screen LCD display shows output DC high voltage, current, overvoltage setting, timing, grounding, and various protection information.
4. It is the first to have intelligent poor grounding protection and alarm function (cannot boost voltage when grounding is poor), voltage measurement circuit disconnection protection (instrument cannot boost voltage when high voltage measurement circuit is disconnected), and emergency stop button, greatly improving operator safety during operation. In special cases, the poor grounding protection alarm function can be disabled (such as when using a generator as power source or when poor grounding on site but testing can still be performed). High precision and accurate measurement. Both voltage and current meters are digital displays, with voltage resolution of 0.1kV and current resolution of 0.1uA. The voltage meter on the control box directly displays the voltage applied to the load test object, no external voltage divider is needed, and wiring is simple. The instrument has high and low voltage end leakage current measurement, and the high voltage end uses a circular shielded digital meter display, which is not afraid of discharge impact, has good anti-interference performance, and is suitable for field use.
5. High voltage adjustment stability, smooth voltage regulation across the full range, output voltage adjustment uses an imported single multi-turn potentiometer, the boosting process is stable, high adjustment precision, and has coarse and fine adjustment functions. Voltage adjustment precision is better than 0.1%, voltage and current measurement error is less than 1.0%, and ripple factor is better than 0.5%.
6. Added high-precision 75% VDC-1mA function, bringing great convenience to zinc oxide arrester measurement. Just a light press, no calculation needed. The control box of this instrument has a 75% voltage function key. When doing arrester tests, when the current rises to 1000uA, press the 0.75 button, then the values displayed on the voltage and current meters are the 75% data. After completion, immediately return the boosting knob to zero, and also return the fine voltage adjustment knob to zero, then immediately press the green button to cut off high voltage and turn off the power switch. Then proceed with other tests.
7. The voltage doubling cylinder has a segmented structure, convenient for field use, flexible, one machine with multiple uses, economical and practical.
8. The voltage doubling cylinder body is developed with German technology; the intermediate frequency transformer is specially designed to be small in size and large in capacity. The base of the voltage doubling cylinder hides △—Y support legs, which unfold into a Y shape when in use for stable and convenient support, and fold into a △ shape when packed, hidden in the base.
