This article discusses how to improve the power supply safety of the power supply system of communication base stations, reduce the failure rate of the power supply system of communication base stations, and improve the network operation efficiency, for. In order to ensure the normal operation of the communication base station, a stable and reliable power supply is necessary. The power demand of communication base station has the following characteristics: Continuous and uninterrupted: communication services require 24-hour uninterrupted operation. Fifth-generation (5G) wireless communications extend the advances of today's 4G networks by addressing the need for increased capacity and throughput, with improved coverage at a lower system cost. High reliability: Multiple backup design to ensure. This acts as the “blood supply” of the base station, ensuring uninterrupted power. It includes: AC distribution box: Distributes mains power and offers surge protection. Battery banks: Serve as backup power to keep. Finding the law of base station power system failure, seeking fast and effective fault solutions, improving the maintenance efficiency of communication base stations, and improving the quality of communication networks have become urgent problems to be solved by the operation and maintenance.
