Summary of the invention
The technical matters of solution required for the present invention is: the clamping tooling providing the mechanical load of photovoltaic module test more accurately of a kind of test result.
For solving the problem, the technical solution used in the present invention is: the clamping tooling of described mechanical load of photovoltaic module test, comprise: a pair long cushion block arranged in parallel, the long cushion block of every bar is provided with at least two fixtures, fixture is bolted inner side aluminum alloy guide rail being fixedly connected on long cushion block, the length of aluminum alloy guide rail is not less than the length of photovoltaic module long margin frame, the chute for holding clamping photovoltaic module long margin frame is provided with in the inner side of aluminum alloy guide rail, two chutes being arranged at the aluminum alloy guide rail on two long cushion blocks are positioned at same level height, thus ensure the photovoltaic module horizontal positioned of clamping, in mechanical load test process, at photovoltaic module surface imposed load, the pair of short edges frame of photovoltaic module bears load.
Further, the clamping tooling of aforesaid mechanical load of photovoltaic module test, wherein, described fixture is L-shaped, the one arm of fixture is fixed on the outside of long cushion block by threaded fastener, another arm of fixture is fixed on the upside of long cushion block by threaded fastener and stretches out long cushion block, and this arm stretching out long block portion is fixed by bolt and aluminum alloy guide rail, aluminum alloy guide rail is ridden in the inner side of long cushion block.
The invention has the beneficial effects as follows: when carrying out mechanical load test, the pair of short edges frame bearing load of photovoltaic module, the result of test is relevant to the short frame length of photovoltaic module, have nothing to do with the support installing hole site that its long margin frame is processed, the error of rack mounting apertures Working position can not affect test result, reliable test result; In addition, in experimentation, the load being applied to photovoltaic module surface is identical, the load that then short frame bears is far longer than the load that the long margin frame between two rack mounting apertures bears, adopt the clamping tooling of said structure, mechanical load testing experiment is more rigorous, and the comprehensive mechanical property detecting qualified photovoltaic module is better.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, technical solutions according to the invention are described in further detail.
As Fig. 2, Fig. 3, shown in Fig. 4, the clamping tooling of the mechanical load of photovoltaic module test described in the present embodiment, comprise: a pair long cushion block 2 arranged in parallel, the long cushion block 2 of every bar is provided with at least two fixtures 3, fixture 3 is bolted inner side aluminum alloy guide rail 5 being fixedly connected on long cushion block 2, the length of aluminum alloy guide rail 5 is not less than the length of photovoltaic module long margin frame 11, the chute for holding clamping photovoltaic module 1 long margin frame 11 is provided with in the inner side of aluminum alloy guide rail 5, two chutes being arranged at the aluminum alloy guide rail 5 on two long cushion blocks 2 are positioned at same level height, thus ensure photovoltaic module 1 horizontal positioned of clamping, in mechanical load test process, at the surperficial imposed load of photovoltaic module 1, the pair of short edges frame 12 of photovoltaic module bears load, described fixture 3 is L-shaped, the one arm of fixture 3 is fixed on the outside of long cushion block 2 by threaded fastener, another arm of fixture 3 is fixed on the upside of long cushion block 2 by threaded fastener and stretches out long cushion block, and this arm stretching out long cushion block 2 part is fixed by bolt 6 and aluminum alloy guide rail 5, aluminum alloy guide rail 5 is ridden in the inner side of long cushion block.
In the process of mechanical load test experiments, first to carry out EL test to photovoltaic module 1, wet leakage tests, peak power test and megger test, the performance guaranteeing the photovoltaic module 1 carrying out mechanical load test is good, then by photovoltaic module 1 clamping on clamping tooling, and by clamping tooling fixed placement on the test platform of mechanical load, adopt the mode of water load toward imposed load on the upper surface of photovoltaic module 1, and progressively increase the numerical value specified in load to IEC61215 standard, then wet leakage tests is carried out to it, best power test and megger test, the performance of photovoltaic module 1 is judged according to test result.When carrying out mechanical load test, pair of short edges frame 12 bearing load of photovoltaic module 1, the result of test is relevant with the length of the short frame 12 of photovoltaic module 1, have nothing to do with the position of the rack mounting apertures that its long margin frame 11 is processed, the error of rack mounting apertures Working position can not affect test result, improves the reliability of test result; In addition, in experimentation, the load being applied to photovoltaic module 1 surface is identical, the load that then short frame 12 bears is far longer than the load that the long margin frame between two rack mounting apertures bears, that is, according to the clamping tooling of long margin frame bearing load making photovoltaic module, photovoltaic module is carried out to the photovoltaic module of mechanical load test and test passes, use the clamping tooling of short frame 12 bearing load again instead, mechanical load test is carried out to same photovoltaic module, then this photovoltaic module might not detect qualified; And according to the clamping tooling of short frame 12 bearing load, photovoltaic module is carried out to the photovoltaic module of mechanical load test and test passes, use the clamping tooling of the long margin frame bearing load making photovoltaic module again instead, mechanical load test is carried out to same photovoltaic module, photovoltaic module is necessarily qualified, that is: adopt clamping tooling of the present invention, mechanical load testing experiment is more rigorous, and the comprehensive mechanical property detecting qualified photovoltaic module entirety is better.
