Embodiment Construction

[0025] figure 1 Shown is the DC remote power supply system diagram of the present invention, the core of which lies in the central office control module. The central office equipment directly supplies power to the communication equipment at the remote or access end through the composite optical cable or power line in the most efficient way by processing the stable -48V power supply in the central office equipment room through the remote power supply. It is not affected by any power failure in the local area of ​​the communication equipment (the access end area). Compared with the indoor unit of the electric equipment, it can be called a permanent power supply, which increases the working utilization rate of the communication equipment and has an intelligent monitoring function. The remote equipment has a wide range of DC high voltage input, secondary isolation boost conversion function to output stable DC power (200V ~ 400V) or -48V, AC220V, power supply for communication equi...

Abstract

The invention discloses a direct-current remote feeding power system, which comprises a local module, a remote module, communication equipment and a local control module, wherein the local control module consists of an input over-voltage / under-voltage protection functional circuit and an output over-voltage and strong-current invasion protection functional circuit; the input over-voltage / under-voltage protection functional circuit detects an input voltage and drives the whole circuit for input over-voltage / under-voltage protection; the output over-voltage and strong-current invasion protection functional circuit limits an output voltage of a local power supply to be equal to or less than direct current (DC) 400 V; and when the output voltage is more than 400 V, a voltage-stabilizing tube is switched on reversely to drive the circuit to operate for over-voltage protection. The direct-current remote feeding power system has the advantages that: the power-off time of the communication equipment is shortened; construction cost, operation cost and maintenance cost are reduced; installation and construction are facilitated; safety for power utilization is improved; and the service life of the communication equipment is prolonged. The direct-current remote feeding power system is widely applicable to construction of mobile base stations, Ethernet passive optical networks (EPCN), indoor or outdoor computer rooms and the like.

Description

Technical field: [0001] The invention relates to the field of communications, in particular to the field of DC remote power supply systems. technical background: [0002] In recent years, my country's communication industry has developed rapidly. The communication power supply is the key infrastructure of the entire communication network and the guarantee for the reliable and stable operation of the entire communication and telecommunication network. The traditional communication power supply has been unable to meet the requirements of modern communication network development due to its low efficiency, high operation and maintenance cost, low reliability and stability. The development of modern communication network has higher requirements for the communication power system. With the popularization and development of 3G network, the problem of power supply and power connection difficulties in the construction of mobile base stations, EPON and indoor and outdoor computer roo...
