RZGF series DC high-voltage generators are developed and manufactured in accordance with the requirements of the Chinese industry standard ZBF 24003-90 "General Technical Requirements for Portable DC High-voltage Generators". They are portable DC high-voltage generators suitable for electric power departments, power departments of factories and mining enterprises, and scientific research units. , Railways, chemicals, power plants, etc. to conduct DC high voltage tests on zinc oxide arresters, magnetic blown arresters, power cables, generators, transformers, switches and other equipment.
RZGF series DC high voltage generator adopts high frequency voltage doubler circuit, the first application of PWM high frequency pulse width modulation technology, closed loop adjustment, and large voltage feedback, which greatly improves the voltage stability. Use high-performance high-power IGBT devices and their drive technology, and adopt special shielding, isolation and grounding measures according to the electromagnetic compatibility theory. The DC high-voltage generator realizes high-quality, portable, and can withstand the rated voltage discharge without damage.
The main components of the RZGF series DC high-voltage generator instrument are selected from the United States, Germany, Japan and other countries to make the instrument more reliable and stable. The pressure doubler barrel is developed and produced by German technology. The high-frequency transformer is specially designed by relevant experts. Small, large capacity, strong overload capacity, convenient for field operation test.
Features
1. Similar products are small in size, light in weight, beautiful and reliable, easy to operate, complete in functions, and easy to use in the field.
2. Adopt advanced technology and process manufacturing, apply PWM intermediate frequency pulse width modulation technology, pulse train logic array modulation, use high-power IGBT devices and large voltage feedback, so that the output high voltage stability is higher and the ripple coefficient is smaller.
3. The main components of the instrument are imported from the United States, Germany, Japan and other countries, which are durable and are not afraid of continuous direct short-circuit discharge to the ground.
4. High precision and accurate measurement. Both the voltage and current meters are digitally displayed, with a voltage resolution of 0.1kV and a current resolution of 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 during use, and the wiring is simple. The instrument has high and low voltage ends to measure the leakage current, and the high voltage end adopts a circular shielded digital meter to display, which is not afraid of discharge shock, has good anti-interference performance, and is suitable for on-site use.
5. High voltage regulation stability, smooth voltage regulation across the entire range, imported single multi-turn potentiometer for output voltage regulation, stable boosting process and high regulation accuracy.
6. Negative polarity output, zero start, continuously adjustable, with various protection functions such as over voltage, over current, zero return, grounding protection, and special disconnection protection. The automatic protection circuit has strong functions, complete and reliable protection, safe operation, and various technical indicators are better than industry standards.
7. The function of high-precision 75%VDC-1mA is added, 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 a lightning arrester test, when the current rises to 1000uA, press the 0.75UDC--1mA button. At this time, the value displayed by the voltmeter and ammeter is 75%. After finishing the data, the potentiometer should be returned to the zero position immediately, and the green button should be pressed immediately to cut off the high voltage and turn off the power switch. Do other experiments.
8. Convenient over-voltage setting function, adopting digital dial switch, can display the setting voltage value intuitively, making your operation more casual, and the unit of display value is kV.
9. The pressure doubler is developed and produced using American technology. The intermediate frequency transformer is specially designed by relevant experts, with small size, large capacity and strong overload capacity, which is convenient for field operation and test.
10-1. There are three built-in support feet at the bottom to increase the stability of the pressure doubler.
10-2. The upper cover of the control box can be used as a windproof base, which can be connected with the pressure doubler to enhance the stability of the pressure doubler.
