GZDW intelligent high-frequency DC control panel
The GZDW DC power-supply panel uses nickel-cadmium batteries, a float charger and automatic monitoring and alarm equipment. It offers long service life, pollution-free operation, convenient maintenance, stable voltage, very low internal resistance, high surge-current capability, adaptability and reliability. It supplies DC operating power for substations and power plants at 500kV and below, and for metallurgy, mining, petroleum, broadcasting, computer rooms, subways and high-rise buildings. Applications include DC control, signaling, power-failure protection and circuit-breaker closing and tripping mechanisms.

Model designation
Normal service conditions
Ambient temperature: -50°C to +40°C, with a 24-hour average not exceeding +36°C.
Altitude: no more than 2500m.
Relative humidity: not more than 50% at surrounding air temperature +40°C.
Higher relative humidity at lower temperatures (e.g. 90% at +20°C), taking into account that temperature changes allow for moderate condensation
The gradient with the vertical side at the time the device is installed shall not exceed 5°.
The equipment should be installed at sites free from severe vibration, shock and corrosion.

Product characteristics
Microphone-controlled dual-way exchange input can be converted automatically.
Exchange input is under pressure, overflow, missing zero automatic detection, displaying and alerting protection.
Charging and floating chargers use the smart high frequency switch currenter module, which combines N+1 redundancy with automatic flow and can be electro-plugged.
Batteries are filled and floated automatically and are functional according to computer settings. Processes such as grid delaying, restoration of transmissions, etc. achieve the management of battery retention intelligence.
In the event of a failure of the micromachine control unit or an error control instruction, the charging module enters an autonomous working state, and the output voltage is the security voltage established for the exit plant to ensure the reliability of the system ' s operation.
The smart four-way system provides detailed communication protocols for communication input, direct-flow output, battery circuits and expanded environmental monitoring, with intelligent interfaces for communication with the integrated automated system of the transformer station.
