Detailed Description
General Information
GDZG-500 DC High Voltage Test Sets is the latest research, design, manufacture, and a new era of technology products ,which is applied to the power sector, industrial enterprises, research institutes, railway, chemical industry , is the ideal equipment for testing DC high voltage of power plants, arrester, power cables, generators, transformers, switches and other equipments .http://www.hvhipot.com/product-57
Features:
Smaller, lighter, more reliable, easy to operate, fully functional ;
This series adopt the latest technique PUM intelligent pulse-width modulation, pulse modulation logic array string, and equipped with high-power IGBT devices, up the frequency to 40kHz, so that the output voltage stability and high ripple factor is smaller ;
3. The large screen LCD display output DC high voltage, current, overvoltage setting, timing, grounding and a variety of protected information ;
The fully functions including : the intelligent poor grounding protection and alarm functions (poor grounding can not step), circuit break protection manometry (pressure measurement instruments can not boost circuit break),
And emergency stop button, greatly improving operator safety in the job process .
5.Grounding protection alarm functions can be lifted in exceptional circumstances(such as the use of generators as a power supply or on-site ground but still test negative in the case). High precision, accurate measurement.
6.Voltage, current meter are digital display, voltage resolution of 0.1kV , the current resolution of 0.1uA, the voltage which is added to the load tested object directly shown on the voltmeter of control box , no external voltage divider in measurement , simple wiring;
7.The instrument has high and low pressure side measuring leakage current, high-pressure side table with circular shield figures show, advanced anti-jamming performance, suitable for field use;
8. voltage regulation and high stability, smooth full-scale voltage regulator, output voltage regulation of imported single multi-turn potentiometer, smooth step-up process , adjustable high precision, and the design of the coarse and fine features. Accuracy of voltage regulationbetter than 0.1%, voltage and current measurement error is less than 1.0%, ripple factor better than 0.5%;
9. New create a high-precision 75% VDC-1mA function , bring great convenience to do MOA measurement . No need to calculate unless one touch;
10. The pressure tube can be divided into sections, use flexibility, multifunctional, cost-effective ;
11. The pressure tube is developed by german technology ,containing △-Y shoring, that is used to develop into Y-shaped, support stable convenience, when packing shrunk △-shaped, hidden in the base period. IF transformer specially designed by the experts, small size, large capacity ;
