Description

Uninterruptible power system

Technical field

This utility model is related to power supply technique field, more particularly, to a kind of uninterruptible power system.

Background technology

Uninterrupted power source technology is widely used in electric power, communication, medical treatment, the emergent field such as place, military affairs, such as operating room The electrical equipment such as illumination, if power failure at crucial moment can cause measureless consequence, and traditional uninterruptible power system is adopted Mode is by access system main road after the series connection of more piece accumulator, supplies electricity to load, when wherein one saves electric power storage after conversion Pond goes wrong or translation circuit goes wrong cannot realize uninterrupted power supply, so the reliability of uninterrupted power source and practicality Property is particularly important.

At present, a kind of uninterrupted power source of achievable fan many gears speed governing, Patent No. cn201520936863.x Utility model patent, solves the problems, such as power-off under the power supply state of emergency, but also has that system reliability is not high and efficiency Low defect.

Content of the invention

This utility model is directed to that in prior art, system reliability is not high and the low shortcoming of efficiency, there is provided a kind of uninterrupted Power-supply system.

In order to solve above-mentioned technical problem, this utility model is addressed by following technical proposals:

Uninterruptible power system, including power factor correction module, conversion module, battery charging module, battery discharge mould Block, accumulator, bypass changeover module and bypass input module, are parallel with battery between power factor correction module and conversion module Charging module, is parallel with battery discharge module and bypass input module between conversion module and load.

Preferably, battery charging module and battery discharge module are in parallel with accumulator, bypass input module and load Between be provided with bypass changeover module.

Preferably, power factor correction module is used for solving electromagnetic interference and electromagnetic compatibility, conversion module is used for city Electric alternating voltage is changed into alternating voltage or the DC voltage that load needs, and battery charging module is used for accumulator is charged, electricity Tank discharge module is used for for the electricity of accumulator exporting load after boosting or conversion.

Preferably, bypass input module and bypass changeover module are used for when civil power not power-off internal system module failure When be switched to bypass circuit to load supplying.

This utility model due to employing above technical scheme, has a significant technique effect:

System adopts modularized design, directly changes module during fault, is easy to safeguard, system reliability is high, battery discharge Efficiency high, the load for direct current supply is particularly suitable for, and reduces single mode block cost and forms cost with system.

Brief description

Fig. 1 is system structure diagram of the present utility model.

Fig. 2 is overall structure diagram of the present utility model.

The toponym that in accompanying drawing, each number designation is referred to is as follows: 1 power factor correction module, 2 conversion modules, 3 battery charging module, 4 battery discharge modules, 5 accumulator, 6 bypass changeover modules, 7 bypass input modules, 8 Load.

Specific embodiment

With embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.

Embodiment 1

Uninterruptible power system, as shown in figure 1, include power factor correction module 1, conversion module 2 and load 8, power It is parallel with battery charging module 3 between factor correction module 1 and conversion module 2, between conversion module 2 and load 8, be parallel with electricity Tank discharge module 4 and bypass input module 7, also include accumulator 5, battery charging module 3 and battery discharge module 4 and accumulator 5 is in parallel, is provided with bypass changeover module 6, power factor correction module 1 is used for solving electromagnetism between bypass input module 7 and load 8 Disturb and realize electromagnetic compatibility, conversion module 2 is used for mains voltage is changed into alternating voltages or the direct current of load 8 needs Voltage, battery charging module 3 is used for accumulator 5 is charged, and battery discharge module 4 is used for the electricity of accumulator 5 through boosting Or after conversion, exporting load 8, bypass input module (7) and bypass changeover module (6) are used for when civil power not power-off system It is switched to bypass circuit to load (8) power supply, while realizing keeping in repair, system also can normal work during internal module fault.

As shown in Fig. 2 being followed by into main circuit with respect to traditional by set of cells series connection, system adopts multiple cell parallels whole The flow module mode in parallel with main circuit greatly reduces and leads to the probability of system cut-off because of battery problems, even if civil power breaks Electricity, accumulator has a section not work still to enable uninterrupted power supply.

In a word, the foregoing is only preferred embodiment of the present utility model, all according to this utility model claim institute The impartial change made and modification, all should belong to the covering scope of this utility model patent.
