1. Overview

GZDW series high frequency switching DC power supply for all kinds of switch and relay protection device for DC operating power supply and power plant as the control and signal equipment with DC power supply, widely used in various types of small and medium-sized power plant and substation (station), electrified railway, large and medium-sized construction and mining enterprises substation, power distribution room and the place needed for emergency lighting of the DC power supply.

2. The characteristics of the system

2.

It is composed of multiple independent modules, N+1 backup;

By using intelligent management, we can complete all functions of charging, charging and floating charging independently, and automatically compensate the battery temperature to prolong the service life of batteries effectively.

The monitoring function is perfect, high intelligence, and equipped with standard communication interface to realize the four remote function.

The insulation detector can be selected and the single battery voltage inspection function can be selected.

The system can expand the other additional functions: increase the inverter to achieve AC distribution output, increase the DC/DC DC conversion module to achieve DC48V (24V) output.

3. The principle of system work

The power supply system is mainly composed of AC distribution unit, charging module, monitoring module, distribution monitoring, step-down silicon chain (depressurization unit), DC feeding unit (including closing and shunting, control shunting), insulation monitoring, battery inspection and so on.

4. Technical indicators

Input voltage: AC 380V + 20%;

Voltage accuracy: less than 0.5%

Current accuracy: less than 0.5%

Ripple coefficient: < 0.5%

The conversion efficiency is not less than 92%a

Noise: less than 55dB (before and after the closure of the door 1 meters)


Order notes

Please indicate the model, the size of the screen and the color.

The capacity and quantity of the supporting battery;

If special requirements are required, it can be designed and processed as required.
