Description
Technical field
The present invention relates to a kind of solar photovoltaic generation system parts, especially relate to a kind of solar photovoltaic assembly terminal box of integral molded plastic formula.
Background technology
The solar photovoltaic assembly terminal box is a vitals in the solar photovoltaic generation system, is between the solar cell array of solar module formation and the connector between the rechargeable solar battery control device.Existing solar photovoltaic assembly terminal box adopts the split-type structural up and down of box body, lid usually, and more components and parts are installed in terminal box, and mainly there is following point in it:
1, technology is loaded down with trivial details, the manufacturing cost height.
Because parts are very many, need to finish a complete terminal box by follow-up assembling, parts are made the process and assemble trouble, and technology is quite loaded down with trivial details, is not easy to automated production, and the manufacturing cost height.
2, volume is big, and heat dispersion is poor.
Existing terminal box generally all is provided with metal terminal, and heat dispersion is poor, and there is cavity in inside, can only dispel the heat by cross-ventilation, and radiating effect is not good, even inner the heat radiation by the casting glue mode can not be obtained more satisfactory effect; Simultaneously, consider reasons such as heat radiation, electric clearance, the volume ratio of terminal box is bigger, not only structurally more complicated, in use damage easily.In addition, because the terminal box heat radiation is bad, causes that the phenomenon that terminal box is burnt occurs repeatedly, even photovoltaic system is caused huge harm.
3, useful life is short.
After existing terminal box opens the lid, inner components and parts are directly exposed in the air, the perishable oxidation of metal part partial volume of components and parts such as electrical equipment terminal, diode, cable in use, working of plastics are aging easily, thereby have shortened the useful life of terminal box greatly.
4, current carrying capacity is poor.
Existing terminal box, the diode between the electrical equipment terminal is generally the tubulose diode, and pin is tiny, and current carrying capacity is poor.Busbar adopts clamped-in style to connect with each input of corresponding electrical equipment terminal mutually, though assembly manipulation is quick, owing to contact connection for line between the conductor, conductive area is little, and contact resistance is big, and connects reliable inadequately, come in contact easily bad, come off phenomenons such as paradoxical discharge.In use, because current carrying capacity is not strong, power consumption is big, and terminal box might be breakdown or be burnt under the circumstances of HTHP.
5, water proof and dust proof poor performance.
Because the environment for use requirement, the water proof and dust proof performance is the important indicator of terminal box performance.The variation of terminal box infiltration or electric clearance, can cause terminal box adverse effects such as components and parts paradoxical discharge, insulation breakdown, short circuit in use to occur, causing that terminal box is damaged burns, and more likely burns assembly and other components and parts of being connected with terminal box, causes serious economy loss.For the cable part, generally all be to seal with sealing nut, in long-term use, sealing nut selects improper owing to material or reasons such as materials are impure, internal stress release, external force collision can cause season cracking, the water proof and dust proof decreased performance; Secondly, for box portion, existing junction box structure is a split-type structural up and down, and aperture area is bigger, the planform complexity, this the just contraction distortion easily in injection moulding process of lid and box body, and the large area to moldings residualinternal stress is also bigger, uses under hot and humid environment for a long time, terminal box expanded by heating inequality can be more prone to distortion, such as the lid warpage occurring, bulge, bare phenomenons such as mouth, and then influenced the water proof and dust proof performance.Aqueous vapor, fine impurity particle etc. will be than being easier to enter box body, can directly contact with components and parts after entering box body, cause serious security incident.
Summary of the invention
The applicant has carried out research and has improved at above-mentioned problem, and a kind of solar photovoltaic assembly terminal box is provided, and technology is simple, low cost of manufacture, and volume is little, perfect heat-dissipating, current carrying capacity is strong, and the water proof and dust proof performance is good, long service life.
