Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component test equipment, in particular to an impact test device for a photovoltaic component. Background Art

[0002] With various extreme weather conditions often occurring. As power generation equipment, photovoltaic modules need to work outdoors for a long time. They must not only experience the continuous test of various harsh environments, but also withstand the impact of various extreme weather conditions, such as hail weather, when extreme weather comes. The hail test is to use a pneumatic launch device to launch artificial ice balls from a certain height at a predetermined speed, hitting the surface of photovoltaic modules at different positions, thereby simulating the impact and impact effect of hail on photovoltaic modules in a natural environment. The air is mainly compressed into the gas tank by an air compressor, and an external pressure gauge and a 25mm inner diameter gun barrel are connected. An air valve is installed at the connection, which is controlled to open by a solenoid valve. A photoelectric speed measuring device is installed at the front end of the gun barrel. Adjust the pressure gauge so that the ice ball reaches the impact speed required by the standard.

[0003] In the prior art, a 25mm ice ball is placed in a gun barrel, and the solenoid valve is opened. Compressed air pushes the ice ball to hit the photovoltaic module at a certain speed. After the module is hit by the ice ball, it is inspected for appearance, tested for maximum power, and tested for insulation resistance to determine whether the module is of qualified quality. Since the diameter of the ice ball and the gun barrel used for pneumatic launch is fixed, generally 25mm, when the photovoltaic module needs to be hit by an ice ball of other specifications, the entire launch device needs to be replaced, which is very troublesome. Therefore, we propose a photovoltaic module impact test device to solve the above problem. Utility Model Content
