Technical field
The utility model relates to technical field of solar, relates in particular to a kind of battery component.
Background technology
In recent years, condensation solar photovoltaic battery module was a dark horse, and had become new fresh combatants of solar energy industry.Solar photovoltaic battery component is as a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), and its fail safe becomes the focus that its user pays close attention to, and the key element of its fail safe is the withstand voltage insulating properties of Blast Furnace Top Gas Recovery Turbine Unit (TRT).
Comprise one or more solar photovoltaic battery components in the device of solar generating, and comprise a plurality of solar battery sheets in each solar module.The encapsulation of any one solar battery sheet and the potential safety hazard of installation all will constitute security threat to the user.
The installation assembling structure of solar battery sheet is: with second rare-solar battery sheet that the rare copolymer EVA of acetic acid second (EthyleneVinyl Axetate) is packaged together is fixed on the insulated substrate by reflow soldering, insulated substrate links to each other with package shell.Insulated substrate is generally aluminium base copper-clad plate or ceramic substrate, promptly is coated with one deck Copper Foil on aluminium sheet or ceramic wafer.Insulated substrate needs to consider electric clearance and two factors of creepage distance in design.Electric clearance is meant between two conductive parts or the shortest space length that records between conductive parts and the equipment protection interface.Creepage distance be meant between two conductive components or conductive component and equipment and easy contact surface between along the shortest space length of insulating material surface measurement.
It is improper but if above-mentioned type of attachment designs, can make electric clearance and creepage distance not to meet the demands, cause the insulated gate punch-through easily, when photovoltaic system voltage during near system's ceiling voltage critical value, the assembly that is in the photovoltaic system can produce very big leakage current, thus the potential safety hazard of causing.So insulated substrate is because of designing deficiency in traditional solar photovoltaic battery component, or the inconsiderate high pressure leaky that causes of high pressure electric leakage security consideration is caused security threat is urgent problem.
The utility model content
In view of this, the utility model provides a kind of battery component, to solve in the prior art because of the not enough security threat that causes of insulated substrate design.Its concrete technical scheme is as follows:
A kind of battery component comprises: battery, insulated substrate, conductive strips, wherein:
Has the insulation layer that satisfies minimum electric clearance distance and the requirement of creepage distance on the described insulated substrate;
What described battery was arranged on insulated substrate covers the copper position;
Described insulated substrate and battery surface are coated with megohmite insulant.
Preferably, described battery is a concentrating solar battery.
Preferably, described insulation layer is positioned at the periphery of insulated substrate.
Preferably, described megohmite insulant is the silicon gel.
Preferably, described battery is arranged on the middle position of insulated substrate by solder reflow.
From above-mentioned technical scheme as can be seen, the disclosed a kind of battery component of the utility model, increase electric clearance and creepage distance by the Copper Foil that erodes certain limit, reduced to make the danger of insulation breakdown and insulation under the given operating voltage and the class of pollution, produce the phenomenon of flashover or puncture because of the crest voltage of transient overvoltage and component internal generation.Coat megohmite insulant on this external insulated substrate and the battery sheet, played double insulated effect, remedied insulated substrate deficiency that ignorance brought to withstand voltage Insulation Problems in manufacturing process.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the package assembly schematic top plan view of the disclosed a kind of battery component of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment discloses a kind of battery component, design electrically-conductive backing plate according to minimum electric clearance distance with creepage distance, avoided because substrate design security threat not enough or that the inconsiderate high pressure leaky that causes of high pressure electric leakage security consideration is caused is a urgent problem.Battery component in the utility model is applicable to low power and high power solar concentrating photovoltaic battery.
Its specific embodiments is as described below:
The disclosed battery component plan structure of the utility model embodiment comprises battery 1, electrically-conductive backing plate 2 and conductive copper 3 as shown in Figure 1.Wherein battery 1 is selected concentrating solar battery for use, and electrically-conductive backing plate 2 is selected aluminium base copper-clad plate for use.Battery 1 is welded on the position that is covered with conductive copper 3 of electrically-conductive backing plate 2 central authorities, except the position that is covered with conductive copper 3, all is insulation layer on the electrically-conductive backing plate 2.
The concrete installation process of the disclosed battery component of present embodiment is:
1, computation module adds minimum electrical spacing and the creepage distance under the magnitude of voltage situation after the twice of maximum system voltage at 1000V.The crest voltage that the size of electric clearance should make the transient overvoltage that enters assembly and component internal produce can not make its puncture.The insulation that the size of creepage distance should make can not produce flashover or puncture (playing trace) under the given operating voltage and the class of pollution.
2, according to the minimum electric clearance distance and the creepage distance of gained, design aluminium base copper-clad plate.Minimum electric clearance distance according to gained is fallen with the peripheral copper corrosion of creepage distance with aluminium base copper-clad plate, forms insulation layer.
