The lead-acid battery of the communication base station adopts the grounding method
Mobile network base stations are generally protected against power loss by batteries. My understanding is that they used to use negative 48V DC power, i. 24 2-volt lead acid cells in series, with positive grounded., set as a 0V reference point), then the entire casing, cabinet, and wiring of the communication equipment will transmit a negative voltage (-48V). Today, it's possible to find these telecom batteries, like those made by Victron. . The communication base station is like the "lighthouse" of the information age, which needs to operate stably all day long, and any instantaneous power interruption may lead to the interruption of communication services, affecting the range from local areas to large user groups, and the. . The method employed in (b) of the diagram may appear to have the best protection since there is a direct path to ground from each appliance. The fact is, that it is not only inadequate, it is not compliant with any accepted electrical code, and does not follow accepted guidelines for electrical. . Telecommunication battery (telecom battery), also known as telecom backup battery or telecom battery bank, primarily refer to the backup power systems used in base stations and are a core component of these systems.
