Research and Application of Sunscreen and Heat Insulation Technology in Power Systems under Extreme High-Temperature Environment

Control cabinets, distribution network cabinets, and secondary warehouses play a crucial role in power equipment. These cabinets house combined units, intelligent terminals, and other essential components. However, due to limited space inside the cabinets, the cooling effect of air conditioning is restricted in high-temperature environments during summer. The internal temperature of these cabinets can soar as high as 60°C, posing a significant risk to the safe and stable operation of critical components. Consequently, our research focuses on the application of sunscreen and heat insulation technology to enhance the climate and environmental adaptability of these cabinets, extend their service life, and improve the overall safety and reliability of the power system.
