product description:

ZGF series of DC high voltage generator is in accordance with the Chinese industry standard ZBF 24003-90 "portable DC high voltage generator general technical conditions" requirements, research and manufacture of portable DC high voltage generator for the power sector, power plant and mining enterprises, scientific research units Railway, chemical, power plants and other zinc oxide arrester, magnetic blowout arrester, power cables, generators, transformers, switches and other equipment, DC high voltage test.

ZGF series of high-voltage high-voltage generator using intermediate frequency voltage doubling circuit, the first application of the latest PWM pulse width modulation technology, closed-loop adjustment, the use of large voltage feedback, the voltage stability greatly improved the use of high performance IGBT devices and Drive technology, and according to the electromagnetic compatibility theory, the use of special shielding, isolation and grounding and other measures. The DC high voltage generator with a high quality, portable, and can withstand the rated voltage discharge without damage.

ZGF series of DC high-voltage generator instrument main components of the United States, Germany, Japan and other countries of advanced technology components, the instrument more reliable and more stable, small pressure cylinder small size, large capacity, overload capacity, easy field test. Companies depending on the quality and credibility of life, and continuously improve the level of science and technology, developed a quality products to meet the needs of users.

Features

1, similar products smaller, lighter weight, more beautiful, more reliable, easy to operate, full-featured, easy to use the field.

2, the use of advanced technology, process manufacturing, the first application of the latest PWM pulse width modulation technology, pulse array array modulation, the use of high-power IGBT devices and voltage feedback, so that the output high voltage stability higher ripple coefficient smaller.

3, the main components of the instrument are selected US, Germany, Japan and other countries imported advanced technology components, durable, not afraid of continuous direct short-circuit discharge.

4, high precision, accurate measurement. Voltage, ammeter are digital display, the voltage resolution of 0.1kV, the current resolution of 1uA, the control box on the voltmeter directly on the load test sample on the voltage value, the use of no need to add Voltage regulator, wiring is simple. Instrument with high and low pressure side of the leakage current measurement, high voltage side of the circular shield with digital display, not afraid of discharge shock, anti-jamming performance, suitable for field use.

5, the voltage regulation of high stability, full range of smooth voltage regulator, the output voltage regulation using a single multi-turn potentiometer, boost process smooth, high precision adjustment.

6, negative polarity output, zero start, continuously adjustable, over voltage, over current, return to zero, ground protection, special disconnection protection and other protection functions. Automatic protection circuit function is strong, reliable and reliable, A variety of technical indicators are better than industry standards.

7, the addition of high-precision 75% VDC-1mA function, do zinc oxide arrester measurement to bring great convenience. Gently press one does not need to calculate the instrument control box with 75% voltage function keys, doing lightning arrester test , When the current rose to 1000uA, press the 0.75UDC - 1mA button, then the voltmeter, ammeter is displayed by the value of 75% of the data, should be done immediately after the regulator potentiometer back to zero And immediately press the green button, turn off the high voltage and turn off the power switch. Do another test.

8, convenient over-voltage setting function, the use of a digital dial switch, the value of the set voltage can be displayed intuitively, so that you operate more casual, the value shown in kV units.

9, times the pressure cylinder with the US technology development and production, the frequency transformer by the experts special design, small size, large capacity, overload capacity, easy to field operation test.

10-1, the bottom with three built-in support feet, an increase of the stability of the times the pressure cylinder.

10-2, the control box cover can be used as a windproof base, can be inserted with the times the pressure cylinder, to enhance the stability of the pressure cylinder.
