It is at present a large amount of in information and networking industry that what use is the general online uninterruption power source that exchanges output.This class uninterrupted power supply, its output voltage is single phase alternating current (A.C.) 220VAC or three-phase alternating current 380VAC in China.In this class ac uninterrupted power supply, earlier by the AC/DC rectification, the input AC electric rectification is become high voltage direct current, back level inverter energy is provided on the one hand, to the energy storage battery charging, power inverter is exported after then this direct current energy being reverse into single-phase 220VAC or three-phase 380VAC AC energy on the other hand.
Because the various electronic equipment overwhelming majority of using in information and networking industry have at present adopted the Switching Power Supply power supply, with regard to its essence, these Switching Power Supplies do not need Alternating Current Power Supply, have direct current supply passable fully, only current current way is to obtain this direct current from Alternating Current Power Supply after over commutation.Therefore, existing interchange output uninterrupted power supply is reverse into AC energy with the direct current energy in the battery, and it is also unreasonable to become the powering mode of direct current through over commutation again to load after.
On the other hand, for improving the information system power supply reliability, the important application occasion adopts the power supply of parallel operation redundant fashion mostly now, but because there is the circulation influence that causes because of phase place, voltage amplitude value difference etc. in AC power, exchange UPS parallel operation system and exist reliability relatively low, shortcomings such as troublesome maintenance.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the defective that exchanges ups system that various electronic equipments use in existing information and the networking industry and the DC uninterrupted electric power system of information network equipment of a kind of low cost, high reliability, high efficiency, easy care and high benefit is provided.
The technical scheme that the utility model adopted is: the DC uninterrupted electric power system of information network equipment, it is characterized in that this system comprises: AC/DC rectifier charging circuit, batteries, direct current output distribution circuit and monitoring unit are wherein, the input termination electric main of AC/DC rectifier charging circuit, its output connects batteries and direct current output distribution circuit.
Described AC/DC rectifier charging circuit is by a plurality of composing in parallel " N+X " redundancy electric power supply system.
For exchanging single-phase 220V or 230V; Or load equipment system in the information network machine room of three-phase 380V or 400V input, the batteries series connection joint number of 12V/ joint is between 22～27 joints, the batteries series connection joint number of 6V/ joint is between 44～54 joints, and the batteries series connection joint number of 2V/ joint is between 132～162 joints.
For load equipment system in the information network machine room that exchanges single-phase 110V or 115V input, the batteries series connection joint number of 12V/ joint is between 11～13 joints, the batteries series connection joint number of 6V/ joint is between 22～27 joints, and the batteries series connection joint number of 2V/ joint is between 66～81 joints.
Described direct current output distribution circuit is composed in series by fuse and D.C. contactor, and D.C. contactor links to each other with output with batteries series connection back.
The beneficial effects of the utility model are: after adopting DC uninterrupted electric power system of the present utility model, compare with existing universal ac uninterrupted power supply system and to have cancelled following circuit: high power DC is to inverter circuit that exchanges and supporting with it interlock circuit; The frequency of output voltage, the detection of phase place and control circuit; Be various supervisory circuits, phase lock circuitry and corresponding software and the algorithm of realizing that multi-machine parallel connection adopts; Step-up transformer or isolating transformer; The bypass commutation circuit.Because the cancellation of these circuit makes DC uninterrupted electric power system of the present utility model have low cost, high reliability, high efficiency, the characteristics of easy care and high benefit.
