Dc Voltage Test System - China

Application

DC voltage test system is widely applied in the DC withstanding voltage test and polarity change- over test of high voltage apparatus, such as high voltage transformers, surge arresters and cables and capacitors.

The DC Voltage test system is designed for indoor use.

Standard

IEC60060- 1, IEC60060- 2, GB/ T16927.1, GB/ T16927.2

Advantages and Features

( 1) Free partial discharge, less than 200pC at DC 1000kV output; less than 300pC at DC1300kV output;

( 2) Fast polarity reversal within 1 minute, polarity change- over time of SCR is less than 5 seconds;

( 3) Earthing system at the output terminal for safety;

( 4) With air cushion at the base for easy and smooth movement.

( 5) Automatic control & measurement system

System Configuration

The test system includes the following main components:

 Charging transformer and HV rectifier

 Post insulator

 AC/ DC cylinder capacitor

 Doubling capacitor

 Corona ring

 Voltage divider

 Damping resistor

 Automatic control and measurement system
