Abstract
The utility model discloses a domestic solar power supply which converts solar energy into 220V /50Hz alternating current power supply, comprising a solar panel, storage cells, a control circuit, a voltage indicating circuit, and an inversion boosted circuit. The utility model is characterized in that a control relay is connected with a switch in series and then connected with the storage cells and a trimmer potentiometer in parallel; the solar panel is connected with the storage cells in parallel through anti-inversion diodes; the two normally open contacts of the relay are respectively connected with the two input terminals of the inversion boosted circuit. According to the principle of photoelectric conversion, the storage cells are charged by the output voltage of the solar panel, and 220V /50Hz alternating current power supply is output through a voltage indication circuit and the inversion circuit. As a result, the electric need of residents' homes in areas with no power or short power supply or frequent power failure is solved.
Description
The utility model relates to a kind of domestic power supply device, particularly a kind of domestic solar power supply.
At present, common family expenses inverter is the AC power that the DC low-voltage of storage battery output is reverse into 220V/50H through inverter, use for household electrical appliance,, provide working power to household electrical appliance by inverter power supply device though its effect also is when the dwelling house electric power system is stopped power supply.But it have one significantly not enough, that is, and to charge in batteries the time, wait the dwelling house electric power system to restore electricity after, by this system to charge in batteries.Like this, it still be unable to do without the electric power system of dwelling house, but also will consume many electric energy, can find out that thus common family expenses inverter right and wrong are energy-saving.
The purpose of this utility model just provides a kind of independent current source that utilizes solar energy to charge in batteries.
The purpose of this utility model is achieved in that by solar panel, battery control circuit, the domestic solar power supply that voltage indicating circuit and inversion step-up circuit are formed.It is characterized in that: the relay J in the control circuit

2Positive pole meet the centre cap D of W
2Negative pole connects the base stage of BG; The end (+) of electrochemical capacitor C meets D
2Positive pole, the other end (-) connects the collector electrode of BG; Resistance R is with after light-emitting diode is connected, a termination power positive pole, and the collector electrode of another termination BG, the emitter of BG connects power supply negative terminal, and described inversion step-up circuit is made up of inversion module T and step-up transformer B.According to the solar photovoltaic utilization principle and the solar cell photovoltaic effect of solar energy, luminous energy is changed into the principle of electric energy.Be subjected at solar panel under the irradiation of certain light intensity, carry out light through energy converter (being solar cell)--after the electricity conversion, by the electric energy of exporting on the solar panel, directly pass to storage battery, promptly to charge in batteries.And by storage battery with the electrical power storage of collecting, in order to the need of household electrical appliance and illuminating lamp electricity consumption.And, in time charge (stopping using) according to the situation that battery tension is indicated.During use, after the control switch closure, the actuating of relay, its normally opened contact adhesive, the entire circuit system connects and starts working.At this moment, the electric energy of battery stores, by transmission circuit to inverter power supply, after the process inverter is reverse into the inversion process of low-voltage AC (frequency is 50Hz) with low-voltage DC, be transformed into the civilian AC power of 220V/50Hz again through the step-up transformer induction, offer the user, Here it is solar domestic power supply.
The utility model is be to solve areas without electricity or shortage of electric power, a kind of device of novel the provided household power energy of resident's domestic lighting in the area that often has a power failure and other electrical equipment electricity consumptions inconvenience and design.It can break away from the dwelling house electric power system fully, has an independently electric power system of one's own.For resident's household electricity provides electric energy.It is simple in structure, and installation, easy to use particularly has energy-conservation distinguishing feature.
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing is circuit theory diagrams of the present utility model.
