4G base station power supply system

Abstract

The invention provides a 4G base station power supply system. The 4G base station power supply system comprises an AC distribution box, an AC distribution unit, a rectification module, a DC distribution unit, a solar cell array, a wind power generation set, a control module, a storage battery and a lightning protection device. The AC distribution box is connected with the rectification module through the AC distribution unit, and the rectification module carries out rectifying and wave-filtering on alternating current distributed by the AC distribution unit and then conveys the alternating current to the DC distribution unit; the solar cell array and the wind power generation set are connected with the storage battery through the control module, and the storage battery provides working power to the DC distribution unit.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a 4G base station power supply system. Background technique [0002] With the development of 4G communication network, the power supply system of 4G base station plays a vital role in the normal and reliable operation of mobile communication network. The existing base station power supply system needs to meet the 7×24 hours of uninterrupted power supply for base station equipment, and also needs to be easy to maintain and expand. With the development of mobile communication networks, the requirements for the base station power system are getting higher and higher, especially for the effective use of the space in the computer room. Multiple single-rack base station power supplies are used in parallel to supply power, and the capacity can be expanded at will to become a large-capacity base station power system. Main trend of base station power supply development. [0003] And ...

AI Technical Summary

Problems solved by technology

[0003] And because the base station equipment needs 7×24 hours of uninterrupted power supply, due to the complexity of the site selection of the base station, some base station computer rooms have limited conditions for providing mains access, and some new energy power supply systems have emerged as the times require, but the current new energy power supply system The lightning protection device still adopts the traditional SPD + circuit breaker lightning protection device. The SPD front-end circuit breaker of this lightning protection device is easy to trip. Since the general-purpose protection circuit breaker at the front of the SPD cannot withstand the lightning impact > 35kA, the circuit breaker after a lightning strike When tripping, the SPD is disconnected from the system, resulting in the loss of protection of the switching power supply and main equipment, and also increases the damage probability and maintenance cost of the base station during the thunderstorm season
