Description
Technical field
The present invention relates to photovoltaic module apparatus field, particularly relate to a kind of modular solar power photovoltaic electrification component wiring box.
Background technology
Wiring box for solar photovoltaic electrification component is applied to solar photovoltaic generation system, is the connector of photovoltaic module and load, and its Main Function is that the electric current produced by photovoltaic module is derived, and provides and be connected with load or the convenient of other photovoltaic modulies.Out of doors in application, terminal box exposes as Blast Furnace Top Gas Recovery Turbine Unit (TRT) and the part of conduction current, and its reliability quality will produce significant impact to component safety.
The structural design of conventional electrical connectors comprises diode component in lid, box body, box body, input contact and output lead.Connect the input contact of terminal box according to solar module lead-in wire, electric current is exported through the output of output lead by box body internal bypass diode, and the box body of this terminal box itself is bigger than normal, correspondingly improves material cost; In box body, diode component is discrete component, connects with fixed by wire insert; With air as heat insulation medium, radiating effect is poor, and power loss is bigger than normal; Along with the power of solar module improves constantly, terminal box body also can not unrestrictedly amplify.Moreover the mode that discrete component is connected and fixed by wire insert, makes contact resistance become large, itself also bring some potential safety hazard to battery component.
The terminal box of existing improvement mostly installs aluminium radiator additional in box, but this radiator is still lid fundamentally should can not solve heat dissipation problem in the box body of terminal box.In addition, the terminal box after improvement still has multiple discrete part combination to form, dismounting combination trouble.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of modular solar power photovoltaic electrification component wiring box, can solve the above-mentioned shortcoming that existing solar photovoltaic electrification component terminal box exists.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of modular solar power photovoltaic electrification component wiring box, comprising: radiating substrate module, diode (led) module and line module; Described diode (led) module and line module are welded in described radiating substrate module.
In a preferred embodiment of the present invention, described radiating substrate module is the aluminium base that surface is pasted with insulating barrier.
In a preferred embodiment of the present invention, described diode (led) module comprises the Schottky diode of more than 3, and is linked in sequence between adjacent Schottky diode.
In a preferred embodiment of the present invention, described line module is the copper sheet be attached to according to line requirements in described radiating substrate module; Described copper sheet is coated with tin layers and insulating barrier successively for the circuit pack surface connecting diode (led) module; The circuit pack surface that described copper sheet is used as lead-out wire is coated with insulating barrier.
The invention has the beneficial effects as follows: a kind of modular solar power photovoltaic electrification component wiring box of the present invention, radiator in existing terminal box is amplified as substrate, and bypass diode and wire are fixed on substrate in the mode of fixing welding, make it into as a whole, not only thoroughly solve the heat dissipation problem of terminal box, and parts each in terminal box are combined into an overall structure, reduce the size of terminal box, facilitate the installation of terminal box in follow-up use procedure, easy to use.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The embodiment of the present invention comprises:
A kind of modular solar power photovoltaic electrification component wiring box, comprising: radiating substrate module, diode (led) module and line module; Described diode (led) module and line module are welded in described radiating substrate module, and this terminal box also comprises the lid covering attached whole described radiating substrate, plays the effect of waterproof, protection.
Described radiating substrate module is the aluminium base that surface is pasted with insulating barrier, and this insulating barrier is the rubber layer of ceramic powder filled.
Described diode (led) module comprises more than 3 Schottky diodes, and is linked in sequence between adjacent Schottky diode; Described Schottky diode is welded on substrate module in the mode of paster, and connects with aluminium base.
Described line module is the requirement according to line design subregion, copper sheet is sintered the conducting circuit formed in radiating substrate module; Wherein, the copper sheet surface for connecting diode (led) module is coated with tin layers and insulating barrier successively; Copper sheet surface as lead-out wire is only coated with insulating barrier, and insulating barrier is herein identical with the insulating barrier in radiating substrate module.
Above-mentioned modular solar power photovoltaic electrification component wiring box, radiator in existing terminal box is amplified as substrate, and bypass diode and wire are fixed on substrate in the mode of fixing welding, make it into as a whole, not only thoroughly solve the heat dissipation problem of terminal box, and parts each in terminal box are combined into an overall structure, reduce the size of terminal box, facilitate the installation of terminal box in follow-up use procedure, easy to use.
