Description

Technical Field

[0001] The utility model relates to the technical field of temperature detection, in particular to a temperature detection device for a photovoltaic power generation panel in a photovoltaic power station. Background Technique

[0002] Vigorously developing renewable energy has become the leading direction of the global energy revolution and response to climate change; in recent years, as an important renewable energy power generation technology, photovoltaic power generation has developed rapidly and has become a clean, low-carbon and price-competitive energy form in many countries. The most important component of photovoltaic power generation is the photovoltaic power generation panel, which is the core component for converting solar energy into electrical energy. The photovoltaic power generation panel does not perform best at too high a temperature, because when the temperature of the photovoltaic power generation panel is too high, its conversion ratio will decrease instead, and too high a temperature will also damage electrical components and cause losses; therefore, the photovoltaic power generation panel is usually equipped with a temperature detection mechanism to monitor and track the temperature of the photovoltaic power generation panel. Existing photovoltaic temperature detection devices usually perform overall temperature detection. Large-sized detection instruments not only block sunlight but also increase the structural load, which is very inconvenient. Moreover, due to the electromagnetic effect, photovoltaic temperature detection devices will attract small particle dust, causing dust accumulation on the surface of the photovoltaic power generation panel and affecting its normal function. After long-term use, the outer surface of the photovoltaic panel may crack, easily causing penetration and resulting in the scrapping of the entire photovoltaic panel, which is very dangerous; therefore, the present utility model makes improvements to the above problems.
