Description
Technical field
The utility model relates to a kind of road lamp system, especially a kind of distributed solar energy road lamp system.
Background technology
Along with the energy totally consumes increase, China has become the large energy resource consumption state of the first in the world, and fall behind by industrial production capacity, energy consumption is higher, expand extensive impact, environmental pollution is day by day serious, the arduous task of environmental improvement, and the photovoltaic regenerative resource as emerging strategic industry effectively can solve development and the contradiction of administering.Increasing as the application utilizing the Solar Street Lighting System of photovoltaic regenerative resource in vast city, street.
The major function of existing each part of Solar Street Lighting System is as follows: (1) solar cell: the effect of solar cell is that the radiant energy of the sun is converted to electric energy, be sent in battery and store, provide the energy to street lamp in the evening, is the core of solar power system.(2) batteries: battery is the key component of system; Its Main Function stores the electric energy that solar array produces by day, evening the fault offset stored out, for load.(3) controller: the effect of controller totally monitors solar cell, battery tension, mains supply and load; For battery provides best charging current and voltage, protect battery simultaneously, avoid overcharge of a battery and overdischarge; The conversion between solar cell and civil power two power supplys is completed, the work that proof load is reliable and stable when needing.(4) utility grid: i.e. public electric wire net, as the stand-by power supply in Solar Street Lighting System system; Overcast and rainy continuously in appearance, battery is not enough due to charging voltage, when can not normally power to the load, is converted to civil power powers to the load by system controller.
Because existing Solar Street Lighting System needs to use battery, and the service life of battery is 3 ~ 5 years, thus increase the operation and maintenance cost of system, and old and useless battery contains heavy metal and the electrolyte solutions such as acid, alkali such as mercury, lead, cadmium, nickel, human body and ecological environment is had to the harm of varying level.Further, through controller, batteries to store energy and dispose procedure after solar cell power generation, conversion efficiency is about 80%, and energy waste is comparatively large, and because of efficiency, need the specification strengthening components and parts, up-front investment is more.
Utility model content
The technical problems to be solved in the utility model is to provide low, the pollution-free and distributed solar energy road lamp system that cost is low of a kind of operating cost.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: it comprises light pole, be arranged on street lamp on light pole and one piece or some pieces of solar panels, it is characterized in that: described electric pole is configured with the combining inverter supporting with solar panels, the electric energy input public electric wire net that solar panel produces by combining inverter; Described street lamp is electrically connected with public electric wire net.
Street lamp described in the utility model controls start and stop by timed unit.
The beneficial effect adopting technique scheme to produce is: the utility model adopts photovoltaic module, solar energy is directly converted to electric energy, directly sends into public electric wire net by combining inverter, and street lamp adopts public electric wire net to power.Like this, while effectively ensureing street lighting, effectively utilize space shared by road lamp system for public electric wire net and electric energy is provided.
The utility model adopts combining inverter, abandons the battery of life-span shorter, contaminated environment, have that cost is low, maintenance cost is low, pollution-free, save the feature of taking up an area space; And without batteries to store energy, eliminate the process of batteries to store energy and release, decrease energy ezpenditure about 10% wherein, there is energy-conserving and environment-protective, good in economic efficiency feature.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1 is solar panel; 2 is combining inverter; 3 is public electric wire net; 4 is light pole; 5 is street lamp.
Detailed description of the invention
Shown in Fig. 1, this distributed Solar Street Lighting System includes light pole 4, and light pole 4 is provided with solar panel 1 and street lamp 5, and solar panel can install 1 piece or polylith as required.Shown in Fig. 1, described light pole 4 is configured with combining inverter 2, the direct current energy that solar panel 1 produces is converted to interchange (AC) electric energy and AC energy is transferred to public electric wire net 3 by combining inverter 2.Described street lamp 5 is electrically connected with public electric wire net 3, realizes power supply by public electric wire net 3; Street lamp power supply, road lamp power supply circuit is provided with timed unit, the illumination of specific time period can be realized, to prevent the waste caused because of daytime illumination by timed unit like this.
After this distributed Solar Street Lighting System adopts said structure, the solar panel of this system institute overlay area just can form distributed grid-connected solar photovoltaic generation system, so not only take full advantage of the feature that solar energy resources is widely distributed, objects such as improving power grid quality, the peak modulation capacity strengthening electrical network, anti-disaster ability and extension ability can also be reached.
