Abstract

The invention provides a wireless distributed base station power supply system, relating to the wireless communication field. The wireless distributed base station power supply system comprises a battery, an AC-DC transformer, a bus bar, a power distribution unit used for distributing electricity energy, a remote cable and a load. The power distribution unit comprises a boosted circuit and a first switch, the battery and the transformer are in parallel connections via the input end of the bus bar, and the output end of the bus bar is connected with the input end of the boosted circuit; the output end of the boosted circuit is connected with the input end of the first switch, the output end of the first switch is connected with the input end of the remote cable, and the output end of the remote cable is connected with the load. The boosted circuit comprises a boost set point, when the voltage of the bus bar is greater than or equal to the boost set point, the boosted circuit does not work; and when the voltage of the bus bar is less than the boost set point, the boosted circuit starts working. By the above scheme of the invention, and under the situation that the battery supplies power, the cross-section of the cable and the height of the power distribution unit are reduced, the cable material cost is reduced, the distance of the remote cable is improved, and the RRU service life is prolonged.

Description
