Description
Technical field
The utility model relates to photovoltaic junction boxes.More particularly to a kind of design scheme of novel photovoltaic junction box.
Background technique
Currently, photovoltaic solar power generation is a kind of inexhaustible；Nexhaustible clean energy resource.Because its safety, it is clean,
Environmental protection and increasingly narrowed by the blueness of people.Photovoltaic industry becomes the rising industry that the whole world is competitively chased, and gets in China
It is added in this industry come more enterprises, China has become the third-largest photovoltaic manufacture base in the whole world, is only second to day
Originally, Germany.Meanwhile the development of solar energy related components industry is also promoted, as photovoltaic terminal box, photovoltaic connect
Device, controller, inverter, battery etc..The power station of photovoltaic industry and related components production assurance are 25 years at present
(25 years time has not been reached yet in power station at home at present).The maintenance of photovoltaic plant and reprocess cost over time
It will constantly increase.After operation 10 years, the failure rate in power station can constantly rise normal general photovoltaic plant.At this moment it will throw
Enter great amount of cost to go constantly to check and repair.Scholar's terminal box by the photovoltaic of the utility model at present, is exactly that face or more exists
Later period potential power station O&M problem solution special design.This product is suitable for the photovoltaic using single photovoltaic junction box
Battery component.The quick-replaceable of the core component diode of photovoltaic junction box can be achieved；Intelligent Power Station and common power station can be achieved
Quickly variation adjustment；Photovoltaic junction box body rapid cooling and high-mechanic current capacity can be achieved.Photovoltaic terminal box conduct
One important component of solar cell module.Photovoltaic junction box is between the solar battery side that solar cell module is constituted
Connector between battle array and solar charging controller for electric consumption.It can be seen that the photovoltaic at the photovoltaic cell component back side connects in photovoltaic plant
Wire box is important one of the building block of photovoltaic plant.It is simultaneously also an important component for being easiest to break down.Because of photovoltaic
The faults itself of terminal box will lead to a series of big disasters, such as: cell piece damage, open circuit, short-circuit power station are burnt.In mesh
Preceding photovoltaic junction box in the market breaks down when reprocessing.It is reprocessed there are two types of scheme, first is that replacement photovoltaic junction box, this will be spent
Many costs of labor will cause power station simultaneously, and locally power-off waits.Also accidentally full wafer photovoltaic module can be carried on the back when shoveling glue
Plate shovel is bad to cause full wafer photovoltaic cell component to scrap.Second is that directly the photovoltaic cell component of this piece together with photovoltaic junction box
It replaces.This is also existing market always with most fast safest main maintenance program.Photovoltaic junction box amount of money ratio in fact
Only the 1.5% of the full wafer photovoltaic cell component amount of money is arrived at station.But just as this 1.5% amount of money failure will lead to 98.5% fund wave
Take.Photovoltaic junction box core component is exactly diode, so generic failure problem 95% is finally diode breakdown.This reality
It with scholar's terminal box by novel photovoltaic is designed for this disadvantage, diode package part and box body welding is distinguished independent envelope
Dress.Then hook stationary positioned is carried out using terminal inserting mode.Welding diode on the terminal of two grafting, formed with
Photovoltaic series cells and connected by-path turn-on effect.Once terminal box diode breaks down bad in this way, as long as just handle
The diode section extraction of photovoltaic junction box re-replaces one and plugs.
It is currently on the market welding diode in copper terminals with the composition of photovoltaic junction box similar in the utility model
On son, positive and negative anodes are riveted with the cable other end with pin and box sub.With plastic casing to the diode terminal riveted
Assembly encapsulation is carried out, after the parallel connection corresponding with the convergent belt that cell piece is drawn of four copper tips is welded in box body, plastic casing
Lumen portion carries out filling conduction heat sealable glue progress waterproof.This structure design method is monoblock type, and diode is with box body welding section
It is intracavitary in a type.This must cause following technical disadvantages: one, can not quickly more when photovoltaic junction box diode breaks down
Change maintenance.Two, tray interior diode radiating is slow, three, be can not be power station plain edition and intelligent fast transition.Four, it repairs
It is at high cost, once problematic need to be full wafer battery pack changing.
Summary of the invention
The technical problems to be solved in the utility model is the following disadvantage of the existing photovoltaic junction box overcome: one, photovoltaic
It, can not quick-replaceable maintenance when terminal box diode breaks down.Two, tray interior diode radiating is slow, three, be can not be electricity
Plain edition of standing and intelligent fast transition.Four, maintenance cost is high, once terminal box is problematic to remove full wafer battery component more
It changes, scholar's terminal box is to provide solution for the design of this disadvantage by the photovoltaic of the utility model.
