Abstract
The utility model discloses an integrated junction box of a solar photovoltaic component, which comprises a box body and a box cover combined with the box body. The utility model has the advantages that: a controller of a solar photovoltaic power system is integrated with the junction box of the solar photovoltaic component, then a lead wire groove is arranged at the bottom of the box body and a left junction hole and a right junction hole are formed on the box body, so that the anode and the cathode lead wires of the solar photovoltaic component can be directly and electrically connected with the controller through the lead wire groove, and the wires of the controller in connection with the load and the storage battery of the solar photovoltaic power system can be led out through the left junction hole and the right junction hole respectively. The integrated junction box of solar photovoltaic component effectively integrates the existing junction box and the existing controller into a whole, omits the wire between the junction box and the controller, has a simple structure and low cost, and can effectively save the space occupied by the controller and simultaneously improve the operating reliability of the controller.
Description
Technical field
The utility model relates to a kind of solar photovoltaic assembly terminal box, especially relates to a kind of solar photovoltaic assembly integrated wiring box.
Background technology
Along with the quick sustainable growth of China's economy, the energy resources environment has become the serious restraining factors that influence future development, under this situation, develops the inevitable choice that regenerative resource has become the China's energy strategy energetically.China's regenerative resource resource potential is huge, especially aspect solar energy resources.According to China's " regenerative resource medium-term and long-term development plan " and photovoltaic generation route map, China will strive that the year two thousand twenty makes the solar power generation installed capacity increase to 8GW by 5MW in 2005, and the year two thousand thirty will reach 30GW.This means that 10 years from present to the year two thousand twenty, the growth rate of China's solar power generation installed capacity will be up to more than 25%.In the world, European Union announces the 20-20-20 plan, and will account for 20% in the year two thousand twenty regenerative resource in energy resource consumption, and wherein the photovoltaic generation target is to account for 12% of total electricity consumption, and the installation before the year two thousand twenty only Europe just might reach 390GW, and market prospects are wide.
Solar photovoltaic generation system is divided into autonomous system and grid-connected system, and grid-connected system is often used for the large-sized solar power station, and autonomous system is often used for small-sized solar power plant or is used for places such as solar street light, navigation light.Autonomous system mainly is made up of solar module, controller and storage battery, also needs to add inverter if load is an AC load.When this solar photovoltaic generation system is used for street lamp or navigation mark indication mechanism, because solar street light, solar energy navigation light etc. are used to place controller, storage battery, also have the space of equipment such as inverter comparatively limited, and electrically connect by lead between each equipment, can make limited space seem in disorder like this, may cause that connection is unreliable simultaneously.How to integrate taking up room of each equipment, make the whole generating system not only attractive in appearance but also reliably will be the direction of solar energy autonomous system development.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of with terminal box and controller effective integration in one, can effectively save taking up room and improving the integrated wiring box of the functional reliability of controller of controller.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of solar photovoltaic assembly integrated wiring box, it is characterized in that comprising box body and the lid that matches with described box body, the controller of solar photovoltaic generation system is arranged in the described box body, the bottom of described box body is provided with the positive pole that is used to introduce solar module, the lead-in wire groove of negative outside wire, and described box body is provided with left wiring hole and the right wiring hole that is used to draw the lead that is connected with described controller.
Described box body is provided with buckle slot, and described lid is provided with buckle, and described buckle slot matches with described buckle.
Be provided with the screw fixed leg in the described box body, be provided with screw in the described screw fixed leg, described lid is provided with and the corresponding through hole of described screw.
Described left wiring hole and described right wiring hole are arranged at respectively on the two side of described box body.
Compared with prior art, advantage of the present utility model is the terminal box of the controller of solar photovoltaic generation system and solar module is combined into one, the lead-in wire groove is set in the bottom of box body again and left wiring hole is set and right wiring hole on box body, the positive pole of solar module like this, negative outside wire can directly be connected with the controller electrode by the lead-in wire groove, and the lead that the load of controller and solar photovoltaic generation system and storage battery electrically connect can be drawn by left wiring hole and right wiring hole respectively, realized existing terminal box and controller are integrated in one effectively, saved the lead between terminal box and the controller, not only simple in structure, cost is low, and effectively saved taking up room of controller, improved the functional reliability of controller simultaneously.
