Description
Technical field
The utility model relates to a kind of intelligent photovoltaic header box, particularly a kind of self-powered photovoltaic header box.Belong to solar power generation auxiliary equipment technical field.
Background technology
Along with the continuous development of heliotechnics, increasing city and enterprise bring into use the solar energy power generating plate to generate electricity.The photovoltaic header box is to be used for tandem multichannel solar photovoltaic assembly, and their groups are gone here and there the visual plant of photovoltaic DC-to-AC converter, is solar power station, the large-scale photovoltaic electricity generation system in building integrated photovoltaic and other commercializations the equipment that must use.In order to monitor the operating state of electric current, voltage and the header box of each road group string in real time, need intelligent monitored control module of configuration in the header box, make it to become intelligent photovoltaic header box.Because the intelligent monitored control module in the intelligent photovoltaic header box needs working power, therefore, prior art all will provide 220V alternating current by the power station; So just need the 220V alternating current be delivered to each intelligent header box through transportion wire separately; Not only to increase the construction and the maintenance cost of wiring, also will increase the cable expense, in addition when situations such as 220V alternating current appearance power failure, outage; To cause the intelligent monitored control module can't operate as normal, finally influence the service behaviour of intelligent photovoltaic header box.In addition under the normal power supply situation, also can partly to isolate the not good RS485 of making PORT COM charged because of AC coupled, thus influence the normal transmission of communication signal.Moreover; Because header box uses mostly out of doors, its operational environment is comparatively abominable, the current value after confluxing higher (about 80～120A); When power lug is loosening in the higher or case when ambient temperature, can burn box equipment or parts because of box house or local device temperature rise.
There is following characteristic in solar energy power generating: when every morning or evening and cloudy day; Because solar illuminance is lower; Cause the generating voltage of silion cell plate low excessively, like this in the photovoltaic generation square formation, when the generating voltage after confluxing is lower than the starting resistor of photovoltaic DC-to-AC converter; Photovoltaic plant can not be to mains supply, and the electricity that send this moment is called " giving up ".This part " gives up " and but is not utilized at present.Therefore be necessary prior art is improved.
Summary of the invention
The purpose of the utility model is to provide a kind of above-mentioned " giving up " that makes full use of in the solar energy power generating square formation, the intelligent photovoltaic header box of supplying power nearby.
The utility model provides a kind of so intelligent photovoltaic header box; Comprise the intelligent monitored control module in casing and the casing, this intelligent monitored control module links to each other with the solar-energy photo-voltaic cell group, and the output of solar-energy photo-voltaic cell group links to each other with electrical network; It is characterized in that being provided with in the casing storage battery with the intelligent monitored control module electrical coupling; With the charge controller of storage battery electrical coupling, this charge controller links to each other with the output of solar-energy photo-voltaic cell group, so that utilize " the giving up " that can not start photovoltaic DC-to-AC converter work of being sent by the solar-energy photo-voltaic cell group every morning or evening or cloudy day; Storage battery is charged; With to intelligent monitored control module power supply, thereby in the electric weight output that does not influence solar energy power generating, realize self-powered to intelligent monitored control module.
Said storage battery also links to each other with other power consumption equipment, to supply power to other power consumption equipment.
Be provided with high-voltage switch gear in the said charge controller; The high-voltage switch gear input links to each other with the output of solar-energy photo-voltaic cell group through power transmission line; The high-voltage switch gear output links to each other with the electric pressure converter input, and the electric pressure converter output links to each other with storage battery, so that the electricity of 60～160V of solar-energy photo-voltaic cell group output is taken out; Through high-voltage switch gear send into convert the 38V Pulse Electric in the electric pressure converter to after, to charge in batteries.
Said intelligent monitored control module is provided with temperature sensor and photovoltaic current sensor; And intelligent monitored control module is through interface, signal transmssion line and power station central controller electrical coupling; With the working temperature in good time detection and the record header box; When temperature surpasses the setting limiting value, can send alarm signal automatically.
Said charge controller is commercial product.
The utlity model has advantage and effect: adopt such scheme; Can make full use of every morning or evening or cloudy day by " the giving up " that can not start photovoltaic DC-to-AC converter work that solar energy power generating group string sends, storage battery charged, to supply power to intelligent monitored control module; Thereby in the electric weight output that does not influence solar energy power generating; Realization is to the self-powered of intelligent monitored control module, and above-mentioned low tension also capable of using has simultaneously not only been saved the cable wiring manufacture and the maintenance cost of 220V alternating current circuit to other power consumption equipment power supply; Also saved the cable consumption in a large number; The investment of reduction cable, because intelligent monitored control module is not influenced by mains supply, therefore equal in any case ability operate as normal; Improving service behaviour, unfailing performance, the stability of intelligent photovoltaic header box, in fact is a desirable solar energy intelligent photovoltaic header box.
