Abstract

The invention discloses a communication power direct current supply system. The system comprises a direct current voltage module which is connected with a DC / DC direct current conversion module and is used for supplying a 220V direct current voltage to the DC / DC direct current conversion module; the DC / DC direct current conversion module which is connected with a load in parallel and is used for converting the 220V direct current voltage into a 50V direct current voltage and outputting the 50V direct current voltage to the load; the load; a storage battery module which is connected with the load in parallel; and a communication power supply module which is connected with the storage battery module in parallel. According to the system, the technical problem of consuming funds and space due to addition of a set of backup communication power and storage battery when faults occur in the communication power and the storage battery of the communication power direct current supply system at the same time in the prior art is solved.

Description

technical field [0001] The invention relates to the field of DC power supply for communication power supplies, in particular to a DC power supply system for communication power supplies. Background technique [0002] At present, the -48V communication power supply is used in the information communication, dispatching and monitoring centers in the buildings of the power bureaus and in the substations to provide DC power supply equipment for various communication equipment such as switches and transmissions without power failure, which effectively guarantees the safe transmission of equipment operating data in each substation. The monitoring center of the bureau building enables the personnel of the monitoring center to monitor and control the operation of each substation at any time, and achieve the purpose of safe operation in the substation without being on duty. In the usual communication power DC power supply system, the parallel floating charge power supply mode is adopt...
