ZGF-200/2 DC High Voltage Generator

1、 Introduction

ZGF-200/2 DC High Voltage GeneratorThe portable DC high voltage generator is researched and manufactured in accordance with the requirements of the Chinese industry standard ZBF 24003-90 "General Technical Conditions for Portable DC High Voltage Generators". It is suitable for DC high voltage testing of equipment such as zinc oxide lightning arresters, magnetic blow lightning arresters, power cables, generators, transformers, switches, etc. in power departments, power plants, research institutions, railways, chemical industries, power plants, etc.

ZGF-200/2 DC High Voltage GeneratorAdopting intermediate frequency voltage doubling circuit, applying new PWM intermediate frequency pulse width modulation technology, closed-loop adjustment, and adopting voltage feedback, the voltage stability is greatly improved. The high-power IGBT devices and their driving technology are used, and special shielding, isolation, and grounding measures are adopted according to electromagnetic compatibility theory. The DC high-voltage generator has high quality, portability, and can withstand rated voltage discharge without damage.

The main components of the DC high voltage generator instrument are selected from advanced technology components from countries such as the United States, Germany, and Japan, making the instrument more reliable and stable. The pressure doubler cylinder has a small volume, large capacity, strong overload capacity, and is convenient for on-site operation and testing. Our company regards quality and reputation as our life, constantly improving our level and developing high-quality products to meet the needs of our customers.

2、 Product Features

1. Similar products are smaller in size, lighter in weight, more aesthetically pleasing, more reliable, easy to operate, fully functional, and convenient for outdoor use.

2. Adopting advanced technology and manufacturing processes, applying new PWM intermediate frequency pulse width modulation technology, pulse train logic array modulation, using high-power IGBT devices and voltage feedback, thus achieving higher output high voltage stability and smaller ripple coefficient.

3. The main components of the instrument are made of advanced technology imported from countries such as the United States, Germany, and Japan, which are durable and not afraid of continuous short circuit discharge to ground.

4. High precision and accurate measurement. The voltage and current meters are both digital displays with a voltage resolution of 0.1kV and a current resolution of 1uA. The voltage meter on the control box directly displays the voltage value applied to the load test sample without the need for an external voltage divider during use, and the wiring is simple. The instrument has high and low voltage ends for measuring leakage current, and the high voltage end is displayed with a circular shielded digital meter, which is not afraid of discharge shock and has good anti-interference performance, suitable for on-site use.

5. High voltage regulation stability, smooth voltage regulation across the entire range, output voltage regulation using imported single multi turn potentiometers, smooth boosting process, and high regulation accuracy.

6. Negative polarity output, zero start, continuously adjustable, with various protection functions such as overvoltage, overcurrent, return to zero, grounding protection, and disconnection protection. The automatic protection circuit has strong functions, reliable protection, and ensures safe operation. All technical indicators are superior to industry standards.

7. The addition of high-precision 75% VDC-1mA function brings great convenience to the measurement of zinc oxide lightning arresters. A gentle press does not require calculation. There is a 75% voltage function key on the control box of this instrument. During the lightning arrester test, when the current rises to 1000uA, press the 0.75UDC-1mA button. At this time, the values displayed on the voltmeter and ammeter are 75% of the data. After completion, immediately return the voltage regulator potentiometer to zero and press the green button to cut off the high voltage and turn off the power switch. Conduct other experiments.

8. The convenient overvoltage setting function adopts a digital dial switch, which can intuitively display the set voltage value, making your operation more flexible. The displayed value is in kV.

9. The double pressure cylinder is developed and produced using American technology, and the intermediate frequency transformer is specially designed by relevant experts to be small in size, large in capacity, strong in overload capacity, and easy to operate and test on site.

10-1. There are three concealed support feet at the bottom, which increase the stability of the pressure doubling cylinder. (Suitable for 200KV)

10-2. The upper cover of the control box can serve as a windproof base, which can be plugged into the pressure doubling cylinder to enhance its stability.
