Abstract
The utility model discloses a high-voltage direct current uninterrupted power supply. The utility model uses the output of high-voltage direct current. The high level end of the output end is connected with the high level end of an energy-storage battery unit, and the low level end of the output end is connected with the low level end of the energy-storage battery unit. The utility model has simple circuit structure, and has no need of secondary conversion of the power supply. Compared with the uninterrupted power supply outputted by the existing common high-voltage alternation current, the utility model has the advantages of low cost, low operation cost and high reliability, and is widely suitable for fields of various electronic devices of information and network industries with, etc.
Description
The utility model relates to a kind of uninterruption power source, particularly a kind of uninterruption power source of high voltage direct current output.
Along with the fast development of information technology and network economy, show data safety problem day important.Therefore, the uninterrupted power supply as one of system patron has also obtained greatly developing and applying.At present, the fixed uninterrupted power supply that uses in worldwide is divided into two big classes: the first kind is the uninterruption power source that is exclusively used in the low-voltage direct current output of telecommunication system.In this class uninterrupted power supply, the energy-storage battery group adopts the battery pack series-fed (annotating: also can adopt 8 joint 6V or 24 to save the battery pack series-fed of 2V) of 4 joint 12V, and the nominal value of its output voltage is direct current 48V.Second class is the uninterruption power source that general high-voltage alternating is exported.What use in a large number in information and networking industry at present is exactly this class uninterrupted power supply, and its output voltage is single phase alternating current (A.C.) 220VAC or three-phase alternating current 380VAC in China.In this class high-voltage alternating uninterrupted power supply, energy-storage battery 1 joint 12V battery or a few joint 12V battery series-feds that adopt in the uninterrupted power supply of small-power and middle power more, the process power inverter is reverse into direct current energy after the AC energy, by step-up transformer output voltage is adjusted to 220VAC output again, and in the powerful uninterrupted power supply, energy-storage battery 16 joints that adopt to 20 joint 12V battery pack series-feds more, the process power inverter is reverse into direct current energy after the AC energy, directly export or export, produce the alternating voltage output of single-phase 220VAC or three-phase 380VAC by isolating transformer.
Because the various electronic equipments that use in information and networking industry have at present all 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, the direct voltage that is exclusively used in the DC uninterrupted power supply output of the 48V low-voltage of telecommunication system is too low again, can not guarantee the Switching Power Supply operate as normal on the various universal electronic devices.
The purpose of this utility model provides a kind of uninterruption power source that can effectively overcome the high voltage direct current output of above-mentioned two class uninterrupted power supply defectives.
The purpose of this utility model is achieved in that its employing high voltage direct current output, the high level end (V of the high level end (+) of output and energy-storage battery group (B)
B+) join the low level end (V of the low level end (-) of output and energy-storage battery group (B)
B-) join.In the system of single-phase 220VAC or three-phase 380VAC Alternating Current Power Supply, energy-storage battery group (B) can adopt 16 joints to 20 joint 12V battery pack series-feds, also can adopt 32 joints to 40 joint 6V battery pack or 96 to save to 120 joint 2V battery pack series-feds, the nominal value of its supply power voltage is direct current 192V to 240V.In the system of single-phase 110VAC and 115VAC Alternating Current Power Supply, energy-storage battery group (B) can adopt 8 joints to 10 joint 12V battery pack series-feds, also can adopt 16 joints to 20 joint 6V battery pack or 48 to save to 60 joint 2V battery pack series-feds, the nominal value of its supply power voltage is direct current 96V to 120V.
After adopting high voltage direct current uninterrupted power supply of the present utility model, compare the secondary conversion of having saved power supply with existing universal ac uninterrupted power supply and 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.Because the cancellation of these circuit makes high voltage direct current uninterrupted power supply of the present utility model have more performance: low production cost, low operating cost, high reliability, high efficiency and high benefit.Thereby has a tangible technological progress.
