Background technology
Along with increasingly sharpening and the raising of human environmental consciousness of energy crisis, the development and use of new forms of energy more and more are subject to people's attention.The energy of solar energy is very huge, is really inexhaustible, the nexhaustible energy, and solar power generation is definitely clean, does not produce public hazards, thus solar power generation to be described as be perfect energy sources.
Though solar power generation is subjected to round the clock, weather, the influence in season, can generate electricity by storage of solar energy is got up again, and generates electricity so it is suitable for the every family distributing.At present, domestic most producers adopt the mode of parallel net type generating, and the electric energy that device of solar generating is produced is connected on the supply network, make each family sell Utilities Electric Co. with it when electric power is rich, then buy in from Utilities Electric Co. when not enough.The technology of realization this point is not difficult to solve, but key is that corresponding legal assurance will be arranged.Because need ammeter counter-rotating work when generating electricity by way of merging two or more grid systems, but China does not also have corresponding laws and regulations to allow the ammeter counter-rotating of average family to use at present.Therefore, this device of solar generating that generates electricity by way of merging two or more grid systems does not conform to average family and civil equipment is used, and therefore needs a kind of solar power plant that is more suitable for promoting of development.
Summary of the invention
In view of this, the utility model purpose is to provide a kind of device of solar generating, adopts the off-grid type conversion, is guaranteeing can not make under the ammeter counter-rotating prerequisite, be implemented in freely switching between solar power generation power supply and the line voltage, can be suitable for vast average family and use.
For solving above technical problem, the technical solution of the utility model is: a kind of device of solar generating, comprise solar energy screen (1) and solar inverter (3), be connected on outdoor outside the described solar energy screen (1), one group lead-in wire is connected with described solar inverter (3), also comprises solar energy screen voltage detecting circuit (8), city's electric detection means (6) and power supply conversion equipment (5); Described power supply conversion equipment (5) is connected between described solar inverter (3) and the power consumption equipment (7); Described power supply conversion equipment (5) also connects described solar energy screen voltage detecting circuit (8) and described city electric detection means (6), by differentiating solar powered voltage and mains-supplied voltage, will switch to solar powered pattern or mains-supplied pattern to the output voltage of described power consumption equipment (7).
More preferably, also comprise two conversion chargers (2) of direct current and battery pack (4); The two conversion chargers (2) of described direct current insert described solar energy screen, and (another group lead-in wire of 1, and be linked into described solar inverter (3) by described battery pack (4) is processed into burning voltage with the unstable direct voltage of solar energy.
More preferably, described solar energy screen (1) is a single-crystalline-silicon solar-cell panel.
More preferably, described solar energy screen voltage detecting circuit (8) is the single-crystalline-silicon solar-cell panel testing circuit.
Compared with prior art, the beneficial effect of the utility model device of solar generating is, can realize the off-grid type generating, guaranteeing can not make under the ammeter counter-rotating prerequisite, can freely switch between solar power generation power supply and line voltage.All be to power to power consumption equipment under general situation, and can not use the civil power of electrical network, thereby can realize the purpose of family or office's economize on electricity preferably by solar energy equipment.
Description of drawings
Fig. 1 is the composition diagram of the utility model device of solar generating one preferred embodiment.
Embodiment
Basic design of the present utility model is, the power supply conversion equipment is set, and can freely switch to solar powered pattern or mains-supplied pattern.
This too can Blast Furnace Top Gas Recovery Turbine Unit (TRT) the course of work be, the unstable direct voltage that the solar energy screen produces is leaded up to behind the two conversion charger circuits of direct current to battery charge, another road is transformed to alternating current by DC-AC converter (inverter) with direct current; The energy by detecting solar energy and the energy value of civil power again, after differentiating by the power supply conversion equipment, the electric energy that provides device of solar generating to produce to the terminal power consumption equipment, or the electric energy that provides of civil power; When device of solar generating can be when power consumption equipment provides enough energy, then by its power supply; In case when not having the illumination or the energy content of battery not enough at night, can automatically civil power be inserted, thereby continue, power incessantly to the terminal power consumption equipment.
For further understanding the basic principle of the present utility model and the course of work, the utility model is described below in conjunction with drawings and Examples.
Referring to Fig. 1, preferred embodiment for the utility model device of solar generating, it is made up of modules such as solar energy screen (being preferably single-crystalline-silicon solar-cell panel) 1, the two conversion chargers 2 of direct current, solar inverter 3, battery pack 4, power supply conversion equipment 5, city's electric detection means 6, power consumption equipment 7, solar energy screen voltage detecting circuits 8, wherein: solar energy screen 1 is drawn through positive and negative lead-in wire, one group of lead-in wire inserts in the two conversion chargers 2 of direct current, and another lead-in wire is connected with solar inverter 3; The two conversion chargers 2 of direct current to battery pack 4 chargings, are linked on the solar inverter 3 after the unstable direct voltage of solar energy is processed into burning voltage again; Solar inverter 3 is converted to alternating current with direct current, inserts in the power supply conversion equipment 5 again; This power supply conversion equipment 5 is judged the energy of city's electric detection means 6 and mono-crystalline silicon solar screen voltage detecting circuit 8 in real time, incessantly, if when the not enough terminal power consumption equipment 7 of the energy (supply power voltage) that solar energy screen 1 provides uses, can be transformed into the mains-supplied pattern automatically; Otherwise, keep solar powered pattern constant.
