Product details
Product overview
GZDW series Cd-Ni batteries for DC screens, floating charge motors and automatic detection and alarm devices are characterized by long service life, no pollution, convenient maintenance, stable voltage, ultra-low internal resistance output, strong adaptability and high reliability. They are ideal DC operation power supply devices. They can be widely used in power plants below 500kV and power plants below 500 kV, as well as in departments such as metallurgy, mining, petroleum, radio and television, computer room, underground railway, high-rise buildings, etc. They can be used as DC control, signal power supply, power cut-off protection and on/off power supply for breaker operating mechanisms.
This product complies with JB/T5777.4-2000《general technical conditions and safety requirements for DC power supply equipment in power system》.
Design feature
Two-way AC input controlled by microcomputer can be automatically converted.
Automatic detection, display and alarm protection for AC input over/under voltage, over current, phase and zero deficiency;
The charging and floating charging device adopts an intelligent high-frequency switching rectifier module, N+1 redundancy is combined, automatic current sharing is realized, and the charging and floating charging device can be plugged and unplugged with electricity;
The battery charging and floating charging processes are automatically switched and can operate normally according to the computer settings. The intelligent floating charge management of storage battery is realized by the procedures of power grid disconnection, power transmission restoration and the like;
When the microcomputer control device fails or sends out an error control instruction, the charging module enters an autonomous working state, and the output voltage is the factory-set safe voltage to ensure the reliability of the system operation.
The intelligent four-remote system provides detailed communication protocols for AC input, DC output, battery circuit and expanded environmental monitoring, and has an intelligent interface for communication with the substation integrated automation system.
