Application Background:
With the continuous development of communication technology and the continuous improvement of network demand, the technology of communication power system is also constantly innovating. In order to ensure the continuity and efficiency of communication services, the power system of telecommunications base stations needs to have high reliability, stability and high efficiency to meet various stringent environmental requirements.
Basic requirements of communication network equipment for power system:
1.High reliability: Multiple backup design to ensure the continuous and stable operation of the system.
2.High stability: Voltage fluctuations, noise and transient voltage must meet the standards to ensure the normal operation of the equipment.
3. High efficiency: Long life, low electricity cost, and optimized power consumption.
4. Good maintainability: Supports automation, intelligence and modular management, which is convenient for fault diagnosis and system maintenance.
The EverExceed base station system is equipped with an AC and DC system, which consists of an AC distribution box/panel, a -48V high-frequency switch combined power supply (including AC distribution unit, high-frequency switch rectifier module, monitoring module, DC distribution unit) and one (or several) batteries.
Base station power system configuration:
1. AC input:
Diesel engine: Provides backup power when the city power is outage.
AC distribution panel: Distributes power to each AC load to ensure the continuous operation of the equipment.
2. Rectifier:
Provides power to communication equipment and charges the battery pack by converting AC power into DC power.
Battery pack:
When the mains power is interrupted, the battery pack provides DC power to the base station equipment to ensure uninterrupted power supply.
3. DC power distribution:
Distributes power according to different capacity loads, and provides protection and alarm functions to avoid equipment failure expansion.
4.Air conditioning system:
Provides a suitable working environment for communication equipment to ensure that the equipment operates under the best temperature and humidity conditions.
1.System monitoring and protection:
2.Intelligent monitoring and protection through protocols such as RS485/SNMP to ensure the safety and stability of the power supply system:
3.Output overload protection: When the load current exceeds the set value, the output is automatically cut off and an alarm is issued.
4.Input undervoltage protection: When the input voltage is lower than the set value, the output is automatically cut off to avoid equipment damage.
5.Overheat protection: When the temperature exceeds the set value, the protection mechanism is automatically triggered to ensure the safe operation of the equipment.
