ZGF-2 series portable DC high voltage generator

ZGF-2 series portable DC high voltage generator

Overview

ZGF-2 microcomputer DC high voltage generator is the renewed portable DC HV generator that our company re-designed and manufactured according to Chinese industry standard of ZBF24003-90 "General technical specifications of portable DC high voltage generator". It is suitable for the power department and power companies apply DC high voltage test on MOA, magnetic blowout arresters, power cables, generators, transformers, breakers and other equipments.

Main properties

This instrument uses a medium frequency double circuit, and firstly put the latest technology of PWM and high power IGBT devices in use. According to the theory of electromagnetic compatibility, it takes special shielding, isolating and grounding measures to achieve non-damaging when under rated voltage discharge and portable at the same time. It also uses modern SCM technology, LCD display to replace the traditional instrumentation and dial switch regulator. It not only retains the original functions of voltage feedback and the 0.75UDC-1mA function specially designed for zinc oxide arrester test, but also ensures that the equipment is small, light weight and portable, and the working frequency are all 30kHz above.
