Description
Technical field:
The present invention relates to the production testing utensil of solar photovoltaic assembly, relate in particular to the investigation instrument of inefficient cell piece.
Background technology:
In preparing the process of solar module, some cell pieces need to be coupled together with array mode in parallel by series, parallel or series connection, to meet different capacity requirement, in silicon chip to be connected, likely having inefficient cell piece sneaks into, or have the cell piece of Partial Power decay to sneak into, above-mentioned phenomenon exists and will have a strong impact on the efficiency of crystalline silicon solar cell modules.The production of solar module is the process that some cell pieces are connected in series and then are encapsulated, in every battery component, require the efficiency of all cell pieces to approach, therefore, before encapsulation, the electric performance test that must use corresponding checkout equipment to carry out short circuit to serial connection cell piece to be packaged, whether normally observe its electrical property curve, because inefficient cell piece arranging in electric battery to be packaged is irregularities, even if it is undesired to detect the electrical property curve of whole battery to be wrapped assembly, can not determine it is which sheet or which sheet solar battery sheet are inefficient, cannot accurately determine the particular location of inefficient cell piece.Because investigation difficulty is large, often can delay the encapsulation production time, therefore, when running into this class problem, normally battery to be wrapped assembly is beamed back and disassembled, remeasure go-on-go, again do over again.This detection and processing make originally only have the battery to be wrapped assembly of the minimum workload of doing over again not only can not immediately be processed, directly affect production efficiency, and in returning to processing procedure, cell piece serial connection part to be installed also can make the cell piece of certified products damage in disassembling process, very uneconomical.
Summary of the invention:
The invention provides a kind of short circuit inspection device of low-efficiency solar battery.It and cell piece short circuit detector are used in conjunction with, and can investigate out the particular location of inefficient cell piece rapidly and accurately.
The technical solution adopted in the present invention is:
The short circuit inspection device of low-efficiency solar battery of the present invention, it is characterized in that: it comprises short circuit contact lever and concertina type connecting link, short circuit contact lever is hinged on the two ends of concertina type connecting link, and short circuit contact lever can rotate with respect to concertina type connecting link, short circuit contact lever and concertina type connecting link are electric conductor.
Further, concertina type connecting link is socketed to form by basic sleeve pipe, intermediate casing and the thinnest sleeve pipe, the thinnest casing pipe sleeve is connected in intermediate casing, all intermediate casings are all socketed in basic sleeve pipe, basis sleeve pipe, intermediate casing and the thinnest sleeve pipe are the good metal sleeve of electric conductivity, outside surface at basic sleeve pipe is provided with insulation course, at the left end of the thinnest sleeve pipe by conductive pin hinge joint short circuit contact lever, right-hand member at basic sleeve pipe links short circuit contact lever by conductive pin, and short circuit contact lever can rotate with respect to the thinnest sleeve pipe and basic sleeve pipe.
Because the present invention has adopted the not only extensible but also contractile structure of concertina type connecting link, short circuit contact lever is hinged on the two ends of concertina type connecting link, and short circuit contact lever can rotate with respect to concertina type connecting link, short circuit contact lever and concertina type connecting link are electric conductor.No matter packed cell piece connects in which way, as long as the both positive and negative polarity at the short circuit contact lever at two ends and mesuring battary sheet two ends is overlapped, access battery component short circuit detector, by observing the electrical property curve of short-circuit test circuit, just can determine exactly it is which sheet or which sheet are inefficient cell pieces, so not only greatly reduced inspection, the difficulty of judging, and can accurately judge the present position of inefficient cell piece, can effectively prevent that inefficient cell piece is encapsulated in battery component, thereby guaranteed the whole photoelectric transformation efficiency of solar module.
