Description

Product Introduction

DBZG-II DC High Voltage Generator is a new product designed according to the new China electric power industry standard DL / T848.1-2004 "DC high voltage generator general technical conditions". This product is mainly used for DC endure experiment to high voltage device such as Electric Power Cooperation, Metallurgy, Iron and Steel enterprises.

 

Product Features

l   The control box is used of aluminum alloy structure.

l   It uses the new technology such as PWM pulse-wide modulation, middle frequency high voltage and high power IGBT device.

l   It uses voltage feedback; output stability is less than 3%.

l   Full range of voltage output, voltage regulating accuracy is less than 1%, the stability of voltage error is less than 1.5%, the voltage error ± (1.5% ±2 words), the current error ± (1.5% ± 2 words).

l   Raise voltage from zero voltage potentiometer.

l   The 0.75UDC/1mA function button is convenient for zinc oxide arrester test, and the accuracy is ±(2%±2words.

l   Over voltage protection uses dialing number set, and the error is ±2%.

l   High voltage cylinder is used of new materials, lightweight and sturdy. It's coated with special insulating materials, electrical performance and moisture-proof ability is good.

l   The product conforms to DL / T848.1-2004 technology requirements, and passed the center test of electrical equipment quality inspection, strictly according to the enterprise standard.
