Abstract
The invention discloses a distributed power supply system. The system comprises a plurality of single boards which need power supply. The system is characterized by comprising power supply modules, a power supply bus and load balancing circuits, wherein the power supply modules are configured on all the single boards; the power supply bus is connected with the single boards and used for supplying power to the single boards; and the load balancing circuits are connected between the power supply bus and each power supply module and used for keeping the power output to the power supply bus by each power supply module equal. At the same time of keeping the advantages of the distributed power supply system, a centralized power supply system can realize hot backup of a power supply board; and the distributed power supply system is suitable for power supply of communication equipment.
Description
Technical field
The invention belongs to the multiplexe electric technology field, be specifically related to a kind of distributed power supply system.
Background technology
Present communication equipment mainly adopts the electric power system of dual mode according to the characteristics of its application requirements: concentration supply power system and distributed power supply system.The concentration supply power system is generally used for the less system of power consumption, and its schematic diagram can be with reference to figure 1.Though the concentration supply power system can realize the function of power panel Hot Spare well, it is bigger for those power consumptions, needs the communication equipment of configuration polylith veneer also inapplicable.Because from the angle of system applies flexibility, the veneer quantity that communication equipment uses is that the demand according to the user disposes, and puts for the simplest configuration and full configuration, and the possible difference of the employed veneer quantity of system is very big.If still adopt the concentration supply power system, in order to satisfy the demand of system upgrade and dilatation, even for the system of simple configuration, power panel also must be configured according to the maximum power dissipation situation, thereby makes system cost too high.In addition, because veneer quantity is many, system power dissipation is very big, so provide enough big power supply on a block power supply plate plate.
Summary of the invention
The object of the present invention is to provide a kind of distributed power supply system, when keeping the distributed power supply system advantage, the concentration supply power system can be able to be realized the power panel Hot Spare.
For reaching goal of the invention, by the following technical solutions:
This equipment of this system comprises the veneer that polylith need be powered, and described system comprises: be configured in every power module on the described veneer; With the power bus that described veneer links to each other, be used for to described veneer power supply; And being connected load balance circuit between described power bus and each the described power module, the power that is used to make each described power module export described power bus to equates.
Further, described load balance circuit comprises protective circuit, is used for staying when detecting power module and this power module and power bus is kept apart when being in overvoltage, under-voltage or over-current state.
Beneficial effect of the present invention:
Distributed power supply system of the present invention still adopts the distributed power supply system structure of an independent current source module of configuration on the every veneer, thereby can be, thereby general distributed power supply system flexible configuration, advantage that cost is low have been kept as required for veneer disposes corresponding power.On the other hand; on system configuration; distributed power supply system of the present invention is the same with the concentration supply power system; all have the power bus that is independent of service bus and pass through this power bus to all veneers power supplies; also need not to switch or the protection of network-level is switched and fixed a breakdown even therefore single power module loses efficacy, thereby improved the reliability of electric power system by other protection of starting device level.
Description of drawings
Accompanying drawing is a supply power mode block diagram of the present invention.
Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is the schematic diagram according to new distribution type power supply system of the present invention.As shown in drawings, communication equipment comprises N piece veneer, and these veneers also are connected into power bus on the backboard to power by power bus except being connected into service bus; All dispose a power module on the every veneer, each power module is connected into power bus through equally loaded circuit separately.In said structure, though the same with the concentration supply power system have a power bus that is independent of service bus, but do not have independently power module, but the same power module that on every veneer, all disposes with distributed power supply system, only these power modules are to link to each other with power bus through load balance circuit.Therefore from supply power mode, power module is directly to its power output in the veneer, but through power bus to the veneer power output.Be connected on power module and the backboard load balancing between the power bus and common concentration supply power system has identical functions, that is, the power that makes power module export power bus to equates.In addition, owing to adopt the power bus structure of concentration supply power system, therefore distributed power supply system of the present invention also can provide the power module warm standby function.
Claims (2)
1. distributed power supply system, this equipment comprises the veneer that polylith need be powered, and it is characterized in that, and described system comprises: be configured in every power module on the described veneer; With the power bus that described veneer links to each other, be used for to described veneer power supply; And being connected load balance circuit between described power bus and each the described power module, the power that is used to make each described power module export described power bus to equates.
2. distributed power supply system as claimed in claim 1 is characterized in that described load balance circuit comprises protective circuit, is used for staying when detecting power module and this power module and power bus is kept apart when being in overvoltage, under-voltage or over-current state.
