Abstract
The utility model discloses a UPS battery capable of enabling redundancy under different working conditions, which is characterized in that an auxiliary power supply comprises a first auxiliary power supply and a second auxiliary power supply; the output ends of the first auxiliary power supply and the second auxiliary power supply are connected; an input end of the first auxiliary power supply is directly connected with a UPS main circuit, a UPS bypass, a UPS busbar or a UPS output. The utility model has the advantages of reducing the design requirements and cost of the auxiliary power supplies since the auxiliary power supplies are respectively connected with the UPS main circuit, the UPS bypass, the busbar or the UPS output to avoid the isolation problem, simplifying the circuits with low cost since the main circuit is not needed for power supply, improving the system reliability since the input ends of the auxiliary power supplies are independent and not influenced by the input source of the auxiliary power supplies, and effectively enabling redundancy under different working conditions of the UPS.
Description
Technical field
The utility model relates to power technology, relates in particular to a kind of redundant ups power of realizing under each operating mode.
Background technology
Accessory power supply provides power supply for the control circuit in the UPS and system, is " heart " of UPS, and its stable and reliability directly influences the normal operation of whole UPS.Under the certain situation of single accessory power supply reliability, realize that Redundancy Design is to improve the important method of reliability.
UPS work has operating modes such as main road power supply, bypass power supply, battery discharge, and Redundancy Design should be able to satisfy various operating modes.Common Redundancy Design is to be the power takings such as main road, bypass, bus of UPS from high-voltage power supply earlier as shown in Figure 1, carries out rectification comprehensively to obtain direct current, articulates two or more accessory power supplys then in the above to realize redundancy; Accessory power supply is transformed to low tension to the control circuit veneer in the UPS with high voltage direct current.This method problem is mainly reflected in following several aspect:
1, range of application limitation: the one, electric pressures such as the main road of voltage range: UPS, bypass, bus differ greatly sometimes, it is comprehensive to want to carry out rectification, must guarantee that voltage ratio is more approaching, otherwise the voltage range after will causing comprehensively is wide, increases the design difficulty and the cost of accessory power supply; Be isolating problem on the other hand, when main road and bypass are not from same electrical network insulation request to be arranged, directly power taking comprehensively can't realize.
2, the redundancy that though accessory power supply has been realized in this scheme, it imports from same power taking synthetic circuit, and the reliability of this synthetic circuit can influence and increase a stability of power supply.
Summary of the invention
The technical problems to be solved in the utility model is to remedy above-mentioned the deficiencies in the prior art, provide a kind of more reliable and stable, can be applicable under each operating mode and to realize redundant ups power.
Technical problem of the present utility model is solved by the following technical programs: realize under a kind of each operating mode comprising first accessory power supply, second accessory power supply by redundant ups power, the output of the two connects altogether; The described first accessory power supply input directly connects at least one road in UPS main road, UPS bypass, UPS bus and the UPS output; The described second accessory power supply input directly connects at least one road in UPS main road, UPS bypass, UPS bus and the UPS output.
Realize redundant ups power under each above-mentioned operating mode, also comprise the 3rd accessory power supply, its input directly connects at least one road in UPS main road, UPS bypass, UPS bus and the UPS output, and output and described first accessory power supply, second auxiliary power output end connect altogether.Also comprise the 4th accessory power supply, its input directly connects at least one road in UPS main road, UPS bypass, UPS bus and the UPS output, and output and described first accessory power supply, second auxiliary power output end connect altogether.
Realize redundant ups power under each above-mentioned operating mode, the input of described first accessory power supply is connected to UPS main road, UPS bypass altogether; The input of described second accessory power supply is connected in the UPS bus, and described the 3rd accessory power supply input is connected in the UPS output.Or the output of described first accessory power supply, second accessory power supply, the 3rd accessory power supply, the 4th accessory power supply is corresponding respectively successively connects UPS main road, UPS bypass, UPS bus and UPS output.
The utility model beneficial effect compared with prior art is: separate because accessory power supply articulates UPS main road, UPS bypass, bus and UPS output respectively, there is not the isolating problem of different input sources, and reduced the designing requirement and the cost of accessory power supply; Owing to no longer need the power taking synthetic circuit, circuit is more succinct, and cost is low; Because the input of each accessory power supply is separate, makes each road auxiliary circuit can not be subjected to the common influence of input source, has improved system reliability, more effectively guaranteed under each work condition state, to realize redundant at UPS.

Embodiment
Embodiment one:
Please refer to Fig. 2, shown in Figure 3, realize redundant ups power under each operating mode of this example, this ups power is the online interaction formula, its secondary power system comprises four accessory power supplys: first accessory power supply, second accessory power supply, the 3rd accessory power supply, the 4th accessory power supply, the input of four accessory power supplys is corresponding respectively successively to be connected with UPS main road, UPS bypass, UPS bus, UPS output, and the output of four accessory power supplys connects altogether.The output of each accessory power supply is separate, can not influence each other, and does not have isolating problem; And saved the power taking synthetic circuit, and circuit is more succinct, and cost is low; Because relatively independent, reliability improves greatly.
Embodiment two:
As shown in Figure 4, realize redundant ups power under each operating mode of this example, its secondary power system comprises three accessory power supplys: first accessory power supply, second accessory power supply, the 3rd accessory power supply, when UPS main road bypass homology, bypass, main road can connect first accessory power supply altogether, the input of all the other two accessory power supplys is connected with UPS bus, UPS output respectively, and the output of three accessory power supplys connects altogether.With last example in like manner, this example still can guarantee four tunnel Redundancy Design of ups power.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.Can be two the tunnel, the three tunnel, the four tunnel etc. such as, Redundancy Design of the present invention; Secondary power system of the present invention also is not limited to and is applied in the on line type UPS power supply, in like manner also can be applied to off-line UPS power supply, online interaction formula ups power.
