Problems solved by technology
[0004]
1. Most of the existing UV aging test chambers are small tower chambers. This small tower chamber has a small volume and capacity and can only test small samples
[0005]
2. The temperature, humidity and irradiance in the box cannot be monitored in real time, and the irradiance uniformity is poor
[0006]
3. Only one solar cell can be tested for photovoltaic module aging at a time, and the efficiency of the test is extremely low
[0007]
4. The distance between the lamp tube and the test sample is fixed and not adjustable

The invention discloses a sample holder and an ultraviolet aging test box for aging test of a photovoltaic module. The sample holder comprises a holder bottom plate, a sliding rail and a holder vertical plate are installed on the holder bottom plate, and a holder top plate is installed on the holder vertical plate. The sliding rail and a frame sliding seat are clamped and assembled in a sliding manner, a sample frame and an adjusting seat plate are respectively mounted on the frame sliding seat, and a frame groove is formed in the sample frame and used for clamping a sample. Hinge lugs are respectively mounted at the upper and lower ends of the adjusting seat plate. The hinge lugs at the upper end and the lower end are hinged to one ends of different width adjusting rods respectively, and the other ends of the width adjusting rods are hinged to width adjusting screw blocks corresponding to the width adjusting rods. The two width adjusting screw blocks are respectively sleeved on a first width adjusting screw rod and a second width adjusting screw rod, one ends of the first width adjusting screw rod and the second width adjusting screw rod are connected, and the other ends of the first width adjusting screw rod and the second width adjusting screw rod are respectively assembled with the holder top plate and the holder bottom plate in a circumferential rotation and non-axial movement manner. The bottom of the second adjusting screw penetrates out of the holder bottom plate, then is installed in a clutch mechanism and is assembled with a worm gear, and the clutch mechanism is installed on the holder bottom plate.
Description
technical field [0001] The invention relates to an environmental test chamber, in particular to a sample rack and an ultraviolet aging test chamber used for aging testing of photovoltaic components. Background technique [0002] Solar cell components are placed outdoors for a long time, and solar cells will absorb sunlight and convert it into electrical energy. However, due to the need to withstand long-term sunlight, the packaging materials of the components will age, which will reduce the service life of the components. Ultraviolet light only accounts for 5-7% of sunlight, but it is the most critical factor causing the aging of solar cell components. Therefore, it is necessary to carry out ultraviolet weather resistance test on solar cells when they leave the factory. The ultraviolet aging test chamber is the test equipment for simulating ultraviolet aging in light. [0003] According to IEC61215-2:2016, the MQT10 UV pretreatment part points out that the UV light source f...
