Description
Technical field
The utility model relates to solar photovoltaic assembly interconnection technique field.
Background technology
Photovoltaic component terminal box is the link of photovoltaic module output, can be used for realizing interconnected between photovoltaic module, thus by the power stage of photovoltaic module to outside, be also the crucial jockey that photovoltaic module is made system.Meanwhile, another effect of photovoltaic component terminal box is to prevent that photovoltaic module part from producing hot spot problem while being blocked.In photovoltaic component terminal box, generally include multiple functional parts, for example for connect photovoltaic module busbar splicing ear, play diode and the cable etc. of bypass effect.
At present, photovoltaic module product is large current low voltage output, and taking general 156mm × 156mm battery as example, the subassembly product voltage of production only has 36V left and right, and electric current is but more than 7A.Photovoltaic module internal structure is that convergent belt couples together battery strings, gets up by material package such as glass, EVA, backboard, frame, silica gel or adhesive tapes, uses the bonding terminal box of silica gel, for the output of assembly on backboard.Inner 10A～20A the diode of installing of terminal box, has pair of output cable.In the process of installation, need the connection in series-parallel of inter-module, reach assembly square formation, generate electricity or charge a battery through grid-connected inverters, form the power generation part in solar power system.Photovoltaic plant, in actual moving process, often burns terminal box, comprise burn diode and burn connector cover and burn box at the bottom of.The photovoltaic module cisco unity malfunction that burns terminal box, electric current cannot normally be exported, and affects power station operation.For avoiding affecting the normal safe operation in power station, burn the photovoltaic module of terminal box and need to change immediately.At this moment a difficult problem of current photovoltaic plant, can only lean on assembly producer depot repair.Photovoltaic plant is usually in remote districts, scarcity; If originally some power station in the time building, assembly is arranged on massif slope, installs pickaback by people's back of the body.Power station floor space is wide, and assembly volume is large, Heavy Weight, and in erecting bed, dismounting is extremely inconvenient.Because packaging after field stripping does not satisfy the requirements, assembly long-distance transport greatly may cause fragmentation, and hidden splitting at least occurs simultaneously.Broken assembly occurs will be scrapped, and the hidden assembly splitting occurs need to be reprocessed, and has greatly increased maintenance, repair cost.Need certain hour owing to changing assembly, affected power station energy output.
Photovoltaic module and the terminal box technical disadvantages of producing both at home and abroad at present, are:
(1) terminal box of the photovoltaic module of producing both at home and abroad, all convergent belt input interface, output lead socket and diode are sealed in a plastic box body, and be made of one with cable, simultaneously all on the insulating back panel of bonding assembly, no matter how terminal box carries out structural design, be also unfavorable for heat radiation.
(2) photovoltaic module is under normal power generation state at present, and diode is in cut-off state.
If but while there is following situation, at this moment diode will forward conduction:
A. certain block assembly all or locally blocked by trees, building, cloud layer etc.;
B. assembly is owing to installing or when operation in later stage suffers that accidental impact produces hidden splitting;
C. the large electric current fill assembly of external system terminal box;
Moreover when power station inverter, header box, transformer etc. are damaged, and system earth is bad, outside generation system high voltage, resonance potential, the electric discharge of static instantaneous pressure etc., make diode reverse breakdown and long-term conducting.No matter be diode forward conducting, or reverse breakdown conducting, diode will generate heat in a large number, and diode pipe leg contact resistance also generates heat simultaneously; During due to generating, electric current is larger, working temperature reaches 200 DEG C, terminal box strictly seals (at least reaching IP65 grade), inside and outside terminal box, be the insulating material that is difficult for heat conduction or poor thermal conductivity, caloric value concentrates on terminal box inside, continue for a long time, at the bottom of often burning diode and connector cover and box.This is the greatest problem of current component application.
(3) on the insulating back panel due to the bonding assembly of terminal box, so need disconnect assembly, depot repair in order to change terminal box.Affect assembly generating, can increase again cost of transportation, transport makes again assembly breakage or hidden splitting, and also greatly increases the expense of reprocessing.
(4) assembly that burns out terminal box needs the reason of depot repair to be: 1. terminal box and assembly become one because silica gel is bonding, particularly casting glue terminal box; 2. single component silica gel curing rate is generally more than 7 days, the more complicated equipment of two component silica gel action need; 3., after the busbar of assembly output damages, can only return factory.
(5) common solar cell operating current is larger, taking 156mm × 156mm battery as example, electric current is in 7A left and right, produce assembly with it and need the convergent belt that sectional area is wider, more flat, softer, but the equal even thickness of the pin of diode package, harder, both connections need to connect by splicing ear, make terminal box volume larger, like this assembly junction box cost higher, can not continue any more.
Therefore, be necessary to provide improved technical scheme to overcome the technical problem existing in prior art.
