Product Description

Product Description

GZDW series (microcomputer controlled) DC power supply cabinet is a new generation of replacement products developed to meet the requirements of unmanned substations for DC power supply cabinets.

It is suitable for large, medium and small power plants and substations, and is used for DC power supply required for high-voltage switch opening and closing, relay protection, automatic control, emergency lighting, etc. in normal operation and accident conditions.

1.It has the charging state selection of main charging, equalizing charging, and floating charging, and the voltage is convenient and adjustable.

2.It has the function selection of voltage stabilization and current limiting and current stabilization and voltage limiting.

3.The microcomputer monitoring unit adopts a large screen and full English LCD display, and the display content includes battery voltage, charging
   current, mother control voltage, charger output voltage, current, single battery voltage and a series of parameters of the DC system.

4.After the AC power is lost and re-entered, the system can automatically select the best charging method to charge the battery according to the
   battery capacity.

5.After the microcomputer monitoring unit exits the system, it does not affect the DC system.

Product Parameters

1.Battery 0 Danger: Complete intelligent battery management Powerful internal resistance analysis
2.Easy to operate: Large touch screen, graphical interface.

Please note:
1. Main circuit scheme number and purpose.
2. Drawings: single-line system, arrangement, distribution room layout, auxiliary circuit wiring principle, terminal arrangement.
3. Components: model, specification, quantity.
4. Requirements for switchgear control, measurement and protection functions and other requirements for locking and automatic devices.
5. If a busbar bridge is required between switchgear or incoming line cabinets, the rated current carrying capacity of the busbar bridge, the span of the busbar bridge, the height from the ground and other specific requirements should be provided.
6. When accessories and spare parts are required, the type and quantity should be specified.
7. The switchgear is used in special environmental conditions, and other special requirements should be detailed when ordering.
