Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panels, in particular to a photovoltaic panel current thermal imaging test device. Background Art

[0002] During the long-term use or after production of photovoltaic panels, an infrared thermal imager is required to detect the performance of photovoltaic panels. Through the thermal imaging of the infrared thermal imager, it can be seen whether there are areas with too high temperature points on the surface of the photovoltaic panel, and whether there are hidden cracks or hot spots, so as to detect the photovoltaic panel;

[0003] In order to facilitate the detection operation of photovoltaic panels, a sealing frame is currently used. The thermal imager is installed at the top of the sealing frame, and the photovoltaic panel to be detected is placed inside the sealing frame. Electrodes are used to discharge the photovoltaic panel, so that after the photovoltaic panel is discharged, the infrared thermal image of the photovoltaic panel after the temperature rises is photographed by the external thermal imager, and then the hot spot position of the photovoltaic panel can be accurately judged to realize the test work of the photovoltaic panel;

[0004] During the detection process of photovoltaic panels, it is not convenient to position the photovoltaic panels when placing them, which may lead to the deviation of the photovoltaic panels. It is not convenient for the thermal imager at the top to detect the deviated photovoltaic panels. At the same time, in order to facilitate the electrodes to be located at the top of the photovoltaic panel for discharging, the electrodes and the sealing frame are usually set to be separated. Therefore, the installation of the electrodes is more cumbersome during the test of the photovoltaic panel, which prolongs the installation time of the photovoltaic panel and is not convenient for use. In view of the deficiencies of the prior art, we propose a photovoltaic panel current thermal imaging test device to solve the above problems. Content of the Utility Model
