The automatic switch has the characteristics of simple circuit, low cost and energy consumption saving. The automatic switch comprises a photovoltaic battery and a storage battery, wherein a cathode of the photovoltaic battery is connected with a cathode of the storage battery, electromagnetic iron cores (10 and 14) are arranged on a fixing board (9), a starting coil (11) and a charging coil (13) are respectively coiled on the electromagnetic iron cores (10 and 14), two elastic metal sheets (5 and 6) swing by using fulcrums (4 and 8) as axis, and the upper end surface of the charging electromagnetic iron core (14) is provided with an insulation slice (7); an anode (1) of the photovoltaic battery is simultaneously connected with the elastic metal sheet (5) and one end of the starting coil (11), the other end of the starting coil (11) is connected to a contact (3), the elastic metal sheet (6) which corresponds to the contact (3) is connected with the cathode (2) of the photovoltaic battery, one end of the charging coil (13) is connected to an anode (15) of the storage battery, the other end of the charging coil (13) is provided with a contact (12), and the elastic metal sheet (5) corresponds to the contact (12). According to the automatic switch disclosed by the invention, automatically switching on and off a photovoltaic power generating and charging circuit in day and night can be realized, the photovoltaic power generating and charging circuit can be automatically switched on when lights appear, and the photovoltaic power generating and charging circuit can be automatically switched off when no light exists; the automatic switch can be suitable for various photovoltaic power generating and charging systems.
Description
technical field:
The present invention relates to automatic control technology field, exactly, it is a kind of photovoltaic generation, Special Automatic switch charges.
background technology:
Photovoltaic generating system is all generally to have by day under the environment of light to generate electricity, and when not generating electricity night, still keeps the state that is connected between photovoltaic generating system and storage battery, just utilizes the characteristic of diode unilateal conduction, avoids the backflow of electric current.But once nitro diode mixed road or short circuit between damage at night, electricity generation system and storage battery (electrical appliance) will cause the damage of whole system, economic loss is large, coefficient of safety is low.If adopt the method for artificial physics switch, early close and open evening, return again to user and bring a lot of unnecessary troubles.
summary of the invention:
Object of the present invention is exactly to solve the problem that photovoltaic generating system daytime, night cannot automatic control switch, the photovoltaic generation of automatically closing when being provided a kind of daytime or having light, automatically disconnecting when night or the dull thread Special Automatic switch that charges.
The object of the present invention is achieved like this, the photovoltaic generation Special Automatic switch that charges, it comprises photovoltaic cell and storage battery, the negative pole of photovoltaic cell is connected with the negative pole of storage battery, it is characterized in that: electromagnetic core (10) and (14) are arranged on fixed head (9), actuating coil (11) and charge coil (13) are respectively on electromagnetic core (10) and (14), it is that axle swings that fulcrum (4) and (8) be take in stretch metal sheet (5) and (6), and the upper surface of electromagnetic core (14) is provided with heat insulating lamella (7).The positive pole of photovoltaic cell (1) is connected with one end of actuating coil (11) with stretch metal sheet (5) simultaneously, the other end of actuating coil (11) is connected on contact (3), be connected with photovoltaic cell negative pole (2) with contact (3) corresponding stretch metal sheets (6), one end of charge coil (13) be connected on the positive pole (15) of storage battery, the other end is provided with contact (12), and stretch metal sheet (5) is corresponding with contact (12).
Advantage of the present invention is: circuit is simple, with low cost, only use two coils and several findings, has just solved the problem of photovoltaic generation, charging daytime, night auto-open-close; The present invention disconnects charging circuit when too small automatically at no current or electric current, when having certain electric current (30-50 milliampere), automatically closes, charges, that is: early morning, low-light was opened voluntarily, and night is rather dark closes voluntarily.The present invention does not waste energy, charge coil self coupling, and the electric energy needing is very little.Ji Ke of the present invention family does certainly, again can batch production batch production; Be applicable to various photovoltaic generations, charging system.
accompanying drawing explanation:
fig. 1 is structural representation of the present invention and circuit diagram
.
embodiment:
embodiment 1:
Electromagnetic core 10 of the present invention and 14, coil 11 and 13 enamelled wire, contact 3 and 12 and other accessory all can buy in electronic market, stretch metal sheet 5 and 6 should be that ferromagnetic material is made, electromagnetic core 10 and 14 mounting distance are little, while guaranteeing charge coil 13 energising, stretch metal sheet 5 can be adsorbed on its end face, the upper surface of electromagnetic core 14 is provided with heat insulating lamella 7, prevents that battery cathode from passing through stretch metal sheet 6 and iron core 14 conductings; The wire diameter of actuating coil 11 should be thinner, and the number of turn should be more, and the wire diameter of charge coil 13 will have the handling capacity of charging current, so wire diameter is wanted greatly.
Morning or while having light, photovoltaic cell generation current, forms closed-loop paths with actuating coil 11, electromagnetic core 10 attracts stretch metal sheets 5, contact 12 closures, and electric current, through charge coil 13, charges the battery; Simultaneously electromagnetic core 14 produces gravitation, when attracting stretch metal sheet 6, also attracts stretch metal sheet 5, and contact 3 disconnects, electromagnetic core 10 dead electricity now, but under the attraction of electromagnetic core 14, stretch metal sheet 5 still keeps original position, continues to charge the battery; The dead electricity of electromagnetic core 10, has saved the energy consumption of a part of photovoltaic cell.When night or dull thread, electromagnetic core 14 suction reduce or without suction, stretch metal sheet 5 and 6 resets, and charging circuit cuts off automatically, and stretch metal sheet 6 is connected with contact 3, and photovoltaic cell and actuating coil 11 form again a closed-loop path.When light occurs again, carry out next one circulation.
