Abstract
The utility model discloses a solar energy and electric network switching and complementing device which is a device which switches over the electricity and conveys the electricity to an electric network after inversely changing the direct current which is emitted by a solar battery into alternating current to generate electricity. The utility model belongs to a novel electricity generating technology with which solar energy photoelectricity is converted into electric energy, and a structure comprises a lightning device, a solar battery board, a controller, a DC load, an accumulator, an inverter, an AC load and the electric network, wherein an electronic chip which automatically controls current is arranged in the controller. A switching switch is arranged among the inverter and the loads, and the utility model has the advantages of automatic switching, safety, no noise, no pollution, little restriction, low failure rate, simple and convenient maintenance, etc.
Description
One, technical field:
A kind of solar energy and electrical network switch compensation device, and what relate to is technical field of solar energy utilization, the particularly technical field of solar photoelectric and electrical network switching device shifter, and it is to utilize the later device that can also convert electric energy to of solar power generation.
Two, background technology:
New forms of energy are one of five big technical fields of tool decision power in the 21st century development of world economy.Solar energy is a kind of cleaning, efficiently and never depleted new forms of energy.Over nearly 20 years, solar-photovoltaic technology and photovoltaic industry develop rapidly in the world wide, and photovoltaic generation progressively turns to the direction of generating electricity by way of merging two or more grid systems and building in conjunction with power supply to develop from solving backwoodsman electricity consumption and special electricity consumption, and development speed is very rapid.
When employing is solar powered, also kept original electric power system, form the powering mode of " supply power with double circuit, photoelectricity is preferential ".The electric weight that stores under a sunny weather can guarantee several overcast and rainy operate as normal continuously.And if the power consumption in the solar cell arrives to a certain degree, system can switch to mains system in 1/30 second time, fully guarantees to power not interrupt.It is big that but existing grid-connecting apparatus exists power consumption, and cost for solar power generation is too high.
Three, summary of the invention:
The objective of the invention is to overcome above-mentioned defective, by solar photovoltaic and electrical network are switched complementary global design, solar energy thermic devices and building are combined, its technology is achieved in that structures such as comprising lightning arrester, solar cell, inverter, controller, DC load, diverter switch, AC load and electrical network, it is characterized in that: the electronic chip that is provided with automatic Control current in the controller, diverter switch is located between inverter and the load, and the model of described electronic chip can be Jn-1A, Jn-2B.The positive effect of implementing after this technology is: have safe and reliable, noiseless, pollution-free, restriction less, advantages such as low, the easy maintenance of failure rate.
Four, description of drawings:
Fig. 1 switches the structural representation of compensation device for a kind of solar energy of the present invention and electrical network.
Wherein 1-lightning arrester, 2-solar panel, 3-controller, 4-DC load, 5-storage battery, 6-inverter, 7-diverter switch, 8-AC load, 9-electrical network.
Five, embodiment:
Below in conjunction with accompanying drawing invention is further described:
See accompanying drawing 1, polysilicon series solar panel (2) connects controller (3) and stores through storage battery (5), the electricity that storage battery (5) stores also can pass through inverter (6) powering load by the direct powering load of controller (3), be provided with diverter switch (7) between inverter (6) and the load, be the anti-lightning strike lightning arrester (1) that is provided with.
See accompanying drawing 1, polysilicon series solar panel (2) via controller (3), controller (3) adopts highly reliable electronic circuit, control multichannel solar wind-energy complementary system is to the automated intelligent type control appliance of charge in batteries and control storage battery powering load, be stored in storage battery (5) then, the electricity that storage battery (5) stores, via controller (3) directly powering load also can pass through inverter (6) powering load, be complementary with power load when inverter is selected for use; The electricity that stores when storage battery (5) is more than for the load electricity consumption time, transmit electricity to electrical network (9) by diverter switch (7) automatic switchover, when the electricity that stores when storage battery (5) is less than for the load electricity consumption again, directly transmit electricity by electrical network (9) to load by diverter switch (7) automatic switchover.Be the anti-lightning strike lightning arrester (1) that is provided with.
Claims (2)
1. solar energy and electrical network switch compensation device, comprise lightning arrester (1), solar panel (2), controller (3), DC load (4), storage battery (5), inverter (6), AC load (8) and electrical network (9), it is characterized in that: be provided with the electronic chip of automatic Control current in the controller (3), diverter switch (7) is located between inverter (6) and the load.
2. switch compensation device according to described a kind of solar energy of claim 1 and electrical network, it is characterized in that: the model of described electronic chip can be Jn-1A, Jn-2B.
