For a long time, freely do not reach the influence of factors such as historical many reasons and traditional custom owing to geographical position, awful weather, traffic, make the culture of Tibetan area and other minority areas and underdeveloped.Compare with low altitude area, interior ground, culture obviously lags behind with science and technology, presents significantly staged drop.Because habits and customs and consumption idea and interior having nothing in common with each other and self-centered traditional demand model that each ethnic group is intrinsic, and the influence of natural environment and geographical environment have seriously been hindered the development of science and culture technology in the minority area.Make that minority area resident's cultural and recreational activity is quite poor.
Specific geographical position and environment have been brought up Tibetan area and other minority areas blocked state for a long time, traditional for a long time begin work at sunrise, sunset and cease, self-centered simple life style can not satisfy the Chinese Minority Nationalities people's the culture and the demand of life ﹠ amusement.Along with the growing process of society, further develop and to enrich the science and technology and the culture life of Tibetan area and other minority areas extremely urgent.
In order to solve the lighting problem in agriculture and animal husbandry area, taked a series of measure, formulate and realized the engineering of energising in every family.Solve the outlying district electrical problem, particularly the electricity consumption solar photovoltaic power in the sufficient area of daylight is a best choice.But present solar photovoltaic power purposes is single, can only throw light on; Power supply self-protection insufficiency face; Particularly alternating current-direct current needs to be met etc. simultaneously, and this has seriously restricted the application and the development of solar photovoltaic power.
Existing counnter attack charge protection device complexity, the incompatibility outlying district particularly need the frequent use needs that flow, and usually power supply does not have anti-lightning strike protective device etc., and fail safe and use stability requirement have a lot of deficiencies in use in special area.
Summary of the invention
The utility model discloses a kind of solar power supply unit that the counnter attack charging circuit is arranged.Problem to be solved in the utility model provides a kind of solar power supply unit, and it can effectively prevent the infringement that unexpected reverse charge causes to power supply unit; The utility model infringement that unexpected high pressure causes to power supply unit such as can also prevent to be struck by lightning.
The utility model is achieved through the following technical solutions:
A kind of solar power supply unit that the counnter attack charging circuit is arranged; comprise solar module, photovoltaic controller, accumulator cell assembly; wherein: photovoltaic controller comprises anti-reverse charge road, additives for overcharge protection circuit, over circuit, power output circuit; described counnter attack charge protector is realized that by the D1 crystal diode it is connected with the charging connecting line.
Further described counnter attack charge protector also comprises resistance R 1 and indicator light D2, and resistance R 1 is with in parallel with the charging connecting line again after indicator light D2 connects.
Further described counnter attack charge protector also comprises and charging connecting line piezo-resistance F2 in parallel.
Outside solar panels input power supply VIN charges the battery by diode D1 in the circuit, utilize the oppositely back discharge of power supply when characteristic guarantees not have solar irradiation of diode, can not uprise suddenly for assurance solar panels input power supply in the circuit, insert resistance R 1, indicator light D2 indication, these two functions that are equivalent to load make solar panels can not be in Light Condition, because the solar panels no-load voltage ratio is higher simultaneously.F2 is a piezo-resistance, prevents instant high-voltage, and is anti-lightning strike.
The additives for overcharge protection circuit is to have used hysteresis comparator circuit, prevents to be full of the concussion of electric critical point by this circuit, and when charging voltage was higher than protection voltage, hummer sent chimes of doom, simultaneously relay automatic disconnection charging circuit.
The over circuit is to have used hysteresis comparator circuit, prevents the concussion of under-voltage protection critical point by this circuit, and when battery tension was lower than protection voltage, controller cut out output automatically and is not damaged with the protection storage battery.This is by a pair of Automatic Protection Switching control, and a protection switch is out that a protection switch is to close off switch automatic disconnection when brownout.
Photovoltaic controller can comprise multiple power supply output socket, can comprise the direct voltage output interface of three 12V, can be used for illumination, satellite receiver, high definition HEVD or the like.A 5V cell-phone charging port, in such information age, it is more convenient, lighter that portable mobile phone gas station allows everybody live.
Above-mentioned each electronic component all has commercially available.
Helpfulness of the present utility model: the utility model has been realized the output of alterating and direct current, and makes power supply more stable, safe, durable owing to the utlity model has the kinds of protect function, and it covers with under the situation about using of loading and can use more than 18 hours continuously most.The application that this has expanded solar powered power supply greatly has good using value.This product can solve multipurpose such as the illumination, multimedia equipment of the family of no electrical network, no optical cable area and short of electricity, wild place's work unit and tourism, frontier defense and use.The utility model can effectively prevent the infringement that unexpected reverse charge causes to power supply unit; The infringement that unexpected high pressure such as can also prevent to be struck by lightning causes to power supply unit.
