Overview

GZDW series microcomputer-controlled DC screen is suitable for substations, power plants, industrial and mining enterprises, electrified railways and high-rise buildings of different voltage levels. It can be used as the operating power supply and control power supply of high-voltage switches, relay protection and automatic devices. The system adopts the integrated design idea, which is composed of monitoring module, rectifier module, insulation monitoring module, battery inspection module, switch monitoring module, step-down module, etc. It has the characteristics of advanced technology, reasonable configuration, intelligent measurement and control, and easy operation. It can communicate with the host computer and conveniently realize the four remote functions of "telemetry, remote control, remote communication and remote adjustment". It is an ideal unattended DC power supply equipment.
