The invention, which belongs to the technical field of the solar photovoltaic modules, provides a photovoltaic module insulation test device and test method. The device comprises a test water tank, atest platform, a test support, an insulation tester and a spraying apparatus. A temperature controlling apparatus for adjusting the water temperature is disposed in the water tank; the test platform is arranged in the test water tank; the test support is supported on the test platform and is used for fixing a to-be-tested photovoltaic module; the insulation tester is positioned outside the test water tank and is used for testing the insulation resistance value of the photovoltaic module; the spraying apparatus is located above the photovoltaic module and used for simulating the rainwater statein the nature. The photovoltaic module insulation test device provided by the invention utilizes the spraying apparatus to simulate natural rainwater, so that the surrounding environment of the photovoltaic module is more truly close to the natural environment, the working insulation performance of the photovoltaic module in a raining state is effectively simulated, the accuracy of insulation resistance testing is improved, and great help is provided for material selection, process optimization and finished product quality of the photovoltaic module.
Description
technical field [0001] The invention belongs to the technical field of solar photovoltaic modules, and more specifically relates to a photovoltaic module insulation testing device and a testing method. Background technique [0002] Photovoltaic modules are the core part of the photovoltaic power generation system, and also the most valuable part of the photovoltaic power generation system. [0003] With the continuous expansion of the terminal market, new materials and new processes are constantly emerging, and photovoltaic modules are applied to wider regions and more complex environments, which requires a deeper understanding of product performance. Only by being more familiar with the actual performance of products in various environments can we provide customers with efficient and reliable photovoltaic module products. [0004] Due to the complexity of the application environment of photovoltaic modules, in addition to being affected by temperature, humidity, wind and s...
