Description
Technical field
The present invention relates to the power supply technique of facility communication system, relate in particular to a kind of power supply system for communications.
Background technology
At present, the most of communication equipment in communications equipment room all uses direct current 48V Power supply.Direct current 48V power-supply system is the power producer of communication equipment, is the infrastructure device of various communication equipments, is called as the heart of communication equipment.
After in a single day the online direct current 48V power-supply system of using comes into operation, can have influence on the operation of online communication equipment due to power failure, therefore general online direct current 48V power-supply device system all go seldom again to have a power failure maintenance, maintenance and maintenance, more can not go to do experiment online, the communication equipment direct current 48V power-supply system that even has all have inspection and maintenance mistake all sidedly from going into operation to run to scrap again.So virtually must increase the potential safety hazard of communication equipment power supply.In addition, in a single day direct current 48V power-supply device breaks down, can only support at short notice by battery discharge the operation of communication equipment, if but the time slightly grow (for example over 1 to 2 hour), when surpassing the load capacity of battery, will cause the paralysis of communication system, and storage battery is caused greatly damage.In addition when communication DC 48V power-supply device rob fix after, communication equipment part also must restart, in case therefore direct current 48V power-supply system breaks down, the fault that communication equipment is caused is lasted long.
Simultaneously, when in a single day the direct current 48V power-supply system of communication equipment breaks down, even standby direct current 48V power-supply system is arranged, but owing to not being on-line joining process, therefore also can extend the time of repairing, on the larger impact of communication equipment generation of on-line operation.
In addition, due to the development of communication, communication equipment makes direct current 48V power supply also will constantly increase also in continuous increase.This just needs dilatation or the transformation of direct current 48V power-supply system, in dilatation or the transformation with system, certainly will exist high risk uninterrupted cutover or local cutover of breaking temporarily.In the past because communication equipment is more dull, generally only have the equipment such as exchange and transmission, less in time-division in morning telephone traffic, power failure cutover and repairing in can the short time, but now class of business is more, and especially data service constantly enlarges and modern times of increase-volume, and be also that data service is busy the time evening, so substantially there is no few time period of traffic carrying capacity, the guarantee of communication equipment power supply had higher requirement.
Summary of the invention
The technical problem that the present invention will solve is to provide a kind of power supply system for communications, can rise to communication equipment power supply reliability and fail safe.
The invention provides a kind of power supply system for communications, be used to communication equipment that electric power is provided.This power supply system for communications comprises primary DC power supply, standby DC power supply and direct current switching equipment, and primary DC power supply and standby DC power supply have the common electrical pressure side, and the other end of primary DC power supply and standby DC power supply is connected with the direct current switching equipment respectively; An end as the communication equipment of load is connected with the direct current switching equipment, and the other end is connected with above-mentioned common electrical pressure side.Wherein, the direct current switching equipment is used for switching primary DC power supply or standby DC power supply provides electric power for communication equipment.
According to an embodiment of the power supply system for communications of the present invention, be connected across the two ends of primary DC power supply as the communication equipment of load, a tie point of communication equipment and primary DC power supply is connected with the direct current switching equipment; Be provided with switch between primary DC power supply and tie point, be used for disconnect and be connected primary DC power supply and be connected connection with communication equipment.And a plurality of branches that the direct current switching equipment comprises wire, is connected with wire, each branch is connected with primary DC power supply or standby DC power supply via switch.
According to an embodiment of the power supply system for communications of the present invention, above-mentioned primary DC power supply is online primary rectification distribution system; Above-mentioned standby DC power supply is online standby rectification distribution system.Online primary rectification distribution system is connected with alternating current respectively with online standby rectification distribution system.
The power supply system for communications provided by the invention, when primary DC power supply breaks down or need maintenance, maintenance, maintenance, switch to standby DC power supply by the direct current switching equipment and provide electric power for communication equipment, the problem of having avoided the reason due to primary DC power supply to cause communication equipment normally not move has improved power-supply system power supply reliability and fail safe.
