Abstract
The invention relates to an uninterruptable power supply system which comprises a voltage stabilizer, a charger, a storage battery and an inverter. Output of a mains supply is connected with the voltage stabilizer and the charger, output of the charger is connected with the storage battery, output of the storage battery is connected with the inverter, and both output of the voltage stabilizer and output of the inverter are connected with a mains supply line to supply power for a load. When the mains supply is inputted to the voltage stabilizer, inputted high or low voltage is adjusted so that stable voltage is outputted, and damage of the load is relieved. The charger functions in charging, and the charger and the voltage stabilizer are connected in parallel, namely, the charger works when the mains supply is inputted. The storage battery stores electric energy of input of the mains supply, the electric energy is used in power failure, and the inverter converts direct current into alternating current supplied for normal operation of the load. The effect of an uninterruptable power supply is achieved, the utilization rate of the power supply is greatly increased, destruction of the load caused by power failure is effectively avoided, and the load can be normally operated in power failure.
Description
Technical field
The present invention relates to a kind of uninterruptible power system, be specifically related to a kind of uninterruptible power system.
Background technology
According to being used at present uninterrupted power supply (UPS) system of computer and computer network system, set out a kind of novel uninterrupted power supply that is applicable to daily life, when civil power is normally inputted, uninterrupted power supply(ups) with the normal voltage stabilizing of civil power after for load, simultaneously it also charges to self-contained battery; When commercial power interruption, uninterrupted power supply(ups) continues supply 220V alternating current with the method that the electric energy of self-contained battery is changed by inversion to load immediately, load is kept worked and protect the load soft and hardware to be without prejudice.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of uninterruptible power system, solved various electron electric power system due to catastrophic failure or outage to the infringement that load causes, make also can work after loading on outage, and reached the recycling of power supply.
To achieve these goals, the technical solution used in the present invention is:
A kind of uninterruptible power system, comprise pressurizer, charger, storage battery and inverter, civil power output connects pressurizer and charger, and the output of charger connects storage battery, the output of storage battery connects inverter, and it is load supplying that the output of pressurizer and the output of inverter all connect the mains-supplied circuit.
The present invention has improved the utilance of electric energy greatly, has realized the recycling of power supply, has reduced the infringement that various electric power systems cause load due to outage.
Description of drawings
Accompanying drawing is electric theory diagram of the present invention, and arrow represents the sense of current.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further details.
In the situation that the normal input of civil power carrying out constant voltage output through pressurizer when, and is charged to storage battery by charger; In the situation that civil power breaks down, the electric energy that storage battery discharges becomes alternating current for the load normal operation through the conversion of inverter.
As shown in drawings, the present invention includes pressurizer, charger, storage battery and inverter, civil power output connects pressurizer and charger, and the output of charger connects storage battery, the output of storage battery connects inverter, and it is load supplying that the output of pressurizer and the output of inverter all connect the mains-supplied circuit.
The course of work of the present invention is: in the situation that civil power breaks down, the electric energy that storage battery discharges becomes alternating current for the load normal operation through the conversion of inverter, realizes the recycling of power supply.
Pressurizer is in the situation that the normal input of civil power is carried out constant pressure adjust to inputting voltage higher or on the low side, exports after voltage stabilization; Charger is under the normal input condition of civil power, converts the alternating current of inputting to low-voltage DC, then storage battery is charged; Storage battery is in the out of order situation of civil power, discharges direct current, and changes it into alternating current for load through inverter.The present invention has realized the recycling of electric energy, thereby has greatly improved the utilance of electric energy, has effectively solved the infringement that various electron electric power system causes load due to catastrophic failure or outage.
Usually in use, when the normal input of civil power, by pressurizer, the voltage of its input is carried out exporting after the adjusting of constant voltage, by charger, storage battery is charged simultaneously; In the situation that break down or suddenly outage, storage battery will be wherein the conversion of electric energy by inverter its direct current is converted to alternating current output, for load normally, reduced the infringement of cutting off the power supply load is caused due to suddenly.
This uninterrupted power supply(ups) causes damage to load due to outage or fault suddenly at present traditional supply unit, and the electric energy that has proposed storage battery is discharged becomes through inverter the device that alternating current output normally moves for load.Due in the situation that civil power is normally inputted, carrying out constant voltage output through pressurizer when, and by charger, storage battery is charged; In the situation that civil power breaks down, the electric energy that storage battery discharges becomes alternating current for the load normal operation through the conversion of inverter, reduces the infringement that load is caused due to fault.
The above; only embodiments of the invention; be not that the present invention is imposed any restrictions, every any simple modification, change and equivalent structure of above embodiment being done according to the technology of the present invention essence changes, and all still belongs in the protection range of technical solution of the present invention.
