Battery rectifier groups in the electrical distribution network are typically powered by 220Vac and provide low-voltage DC outputs such as 24Vdc or 110Vdc. The primary purpose of these groups is to supply power to protection and monitoring equipment (such as protection relays, RTUs, energy analyzers, etc.) that operate on DC voltage in places like electrical distribution centers or substations. They ensure that this equipment remains operational even when the grid power is unavailable. Additionally, they isolate the equipment from the grid when grid power is present, ensuring safety.

Functions:

1.Providing Uninterrupted Power Supply: Battery rectifier groups are designed to keep protection and monitoring equipment running uninterruptedly during any power outage or when the energy source is unavailable.
2.Protection Against Power Fluctuations: In the event of abnormal fluctuations or sudden voltage changes in the grid power, battery rectifier groups filter these fluctuations to protect the connected equipment.
3.Battery Charge and Discharge Management: Battery rectifier groups charge the batteries when grid power is available and discharge them to provide energy when needed. This extends the battery life and enhances the capacity to provide a reliable power supply.
4.Grid and Battery Isolation: When grid power is available, battery rectifier groups isolate the connected equipment from the grid. This prevents damage to the protection and monitoring equipment in case of any issues or faults in the electrical grid.

Features:

1.High Efficiency and Reliability: Battery rectifier groups provide a continuous power supply with high efficiency and reliability, ensuring the safety and continuous operation of critical equipment.
2.Modular Design and Expansion Flexibility: Some battery rectifier groups have a modular structure, making it easy to expand the systems or increase capacity.
3.Automatic Alarm and Monitoring Systems: Battery rectifier groups are equipped with automatic alarm and monitoring systems. These systems alert users in case of any issues or faults, enabling quick intervention.

Points to Consider:

1.Battery Maintenance and Replacement: Regular maintenance of battery rectifier groups and timely replacement of batteries are crucial. This increases system reliability and prevents unexpected failures.
2.Load Profile and Capacity Planning: Proper load profile and capacity planning are essential. In case of overloading, system performance may decrease, or critical equipment may remain unprotected due to insufficient capacity.
3.Considering Environmental Conditions: The temperature, humidity, and other environmental factors of the installation environment for battery rectifier groups should be considered. These factors can affect system performance and lifespan.
4.Manufacturer Selection and Service Support: Choosing battery rectifier groups from a reliable manufacturer or supplier and ensuring technical service support is important. This ensures the systems operate long-term and reliably.
