Abstract
The utility model relates to an uninterrupted power supply, comprising an inversion instrument and a storage battery which is connected with the direct current input terminal of the inversion instrument. The uninterrupted power supply is also provided with a current converting device which can convert alternating current to direct current, and the output of the converting device which can convert alternating current to direct current is respectively connected with the direct current input terminal of the inversion instrument and the storage battery. After the input of the current converting device which can convert alternating current to direct current is connected with the output of a generator, the power supply of the utility model can realize the alternate switching between two power supply forms which are generator power supply and storage battery power supply. Moreover, the higher requirements for the generator can be avoided, and the cost can be reduced.
Description
The utility model belongs to the equipment to the load continued power, is specifically related to utilize the contravariant equipment equipment of powering load for a long time.
Along with the progress of society, more and more equipments or department need continual power supply at present, and civil power is often because the situation that the failure and other reasons appearance has a power failure; So can not meet the demands.So these equipment or department adopt generator or uninterrupted power supply to deal with emergencies such as municipal power failure.But the power of generator generally adopts equipment such as diesel engine, these equipment need maintenances such as oiling, maintenance after work a period of time, so can not long-time continual use, and the voltage that produces of generator and frequency instability requirement of also being not suitable for modern comfort; And electric power of equipment such as uninterrupted power supply need be provided by storage battery etc., but the capacity of storage battery is limited, so by the capacity decision of storage battery, can not guarantee uninterrupted for a long time the use service time.
The purpose of this utility model is, provides a kind of and alternately provides electric power by generator and storage battery for addressing the above problem, and realizes long-time uninterrupted power supply, and the power supply of the stable sustainable power supply of voltage.
For addressing the above problem, the utility model is the power supply of so a kind of sustainable power supply that realizes, comprise contravariant equipment and the storage battery that is connected with this contravariant equipment direct-flow input end, the power supply of described sustainable power supply is provided with and exchanges the current converter convert direct current to, and the output that this interchange converts the current converter of direct current to connects the direct-flow input end and the storage battery of described contravariant equipment respectively.
Above-mentioned contravariant equipment is uninterrupted power supply or frequency converter.
Advantage of the present utility model and good effect be, after the input that interchange is converted to the current converter of direct current connected the output of generator, power supply of the present utility model can realize that generator powered and alternately switching of two kinds of power supplies of storage battery power supply forms use.The long uninterrupted power supply of realization that can be practical.The utility model is transformed into the dc terminal that direct current is input to contravariant equipment with the alternating current that generator produces, and can avoid the high requirement to generator, has reduced cost; When being input to the interchange end of contravariant equipment, because the fluctuation of alternating current that generator produced is bigger, checkout equipment can cut off the input of generator automatically, so common generator is during as the power supply input of high requirement, usually cut off automatically by contravariant equipment, can not be as power supply.If adopt the generator cost of high requirement very high, be not suitable for using.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the circuit diagram of the current converter of an embodiment of the utility model.
As shown in Figure 1, a kind of power supply of sustainable power supply, comprise contravariant equipment 1 and the storage battery 2 that is connected with this contravariant equipment 1 direct-flow input end, the power supply of this sustainable power supply is provided with and exchanges the current converter 3 convert direct current to is the AC/DC conversion equipment, and the output that this interchange converts the current converter 3 of direct current to connects the direct-flow input end and the storage battery 2 of described contravariant equipment 1 respectively.
Contravariant equipment 1 can be that uninterrupted power supply is UPS or frequency converter.
As shown in Figure 2, exchanging the electric power conversion apparatus 3 that converts direct current to is common AC/DC conversion equipments, the power match of requirement and generator G, and wherein a kind of physical circuit is the three-phase bridge translation circuit.
Contravariant equipment 1 can be that uninterrupted power supply is UPS or frequency converter.
When the utility model uses, generator G is connected interchange convert dc converter 3 to, when if power outage occurring, can be by storage battery 2 power supplies, when if the electric energy in the storage battery 2 is reduced to a certain degree, can starter-generator G, be transformed into behind the direct current accumulators 2 power supplies powering load simultaneously by the alternating current of generator G.
