Fixtures for mechanical load testing of photovoltaic modules

Abstract

The invention discloses a clamping tool for testing the mechanical load of a photovoltaic module. The clamping tool comprises a pair of long cushion blocks arranged in parallel, wherein each long cushion block is provided with at least two clamps, the clamps are connected through bolts to fixedly connect an aluminum alloy guide rail onto the inner sides of the long cushion blocks, the length of the aluminum alloy guide rail is not less than that of each long side frame of the photovoltaic module, a slide slot for accommodating and clamping each long side frame of the photovoltaic module is arranged on the inner side of the aluminum alloy guide rail, the two slide slots of the aluminum alloy guide rail arranged on the two long cushion blocks are located at the same horizontal heights, so that the clamped photovoltaic module is guaranteed to be placed horizontally. According to the clamping tool provided by the invention, the reliability of a test result is improved, the mechanical load test is more precise, and the comprehensive mechanical performance of the photovoltaic module passing the test is better.

Description

Technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a clamping tool for mechanical load testing of photovoltaic modules. Background technique [0002] With the continuous development of the global economy, energy consumption has continued to increase accordingly. Because of its pollution-free and renewable nature, photovoltaic modules are being valued, developed and widely used. In order to ensure the safety and quality of photovoltaic modules, they need to be Testing, mechanical load testing is an important part of photovoltaic module testing, mainly used to test the ability of photovoltaic modules to withstand static loads such as wind, snow or icing; IEC61215 standard (crystalline silicon photovoltaic modules for ground use-design qualification and finalization ) Clearly stipulates the test purpose, test requirements and judgment criteria of the mechanical load test, but does not stipulate the installation method of the test s...

Problems solved by technology

During the mass production of photovoltaic modules, due to the existence of various factors such as the error of processing accuracy and the accuracy error of the processing machine itself, there will be certain position errors in the mounting holes of the brackets at both ends of the long frame of each photovoltaic module. In the load test, the load on the surface of each photovoltaic module is the same, but there will inevitably be errors in the position of the bracket mounting holes on each photovoltaic module, so the distance between the long frames between the two bracket mounting holes is different, resulting in The results of multiple test experiments are different, and the test results are difficult to accept
