科研登高不畏难 创新突破勇当先

Core Viewpoint - The article highlights the innovative achievements of Du Baoshuai and his team at the State Grid Shandong Electric Power Research Institute, focusing on their breakthroughs in addressing critical issues in the electric power industry, particularly related to gas leakage and pollution flashover prevention. Group 1: Innovations in Gas Leakage Solutions - The GIS (Gas Insulated Switchgear) is a core device in the power grid, with gas leakage being a common defect that poses safety and environmental risks due to the high global warming potential of sulfur hexafluoride (SF6) [3][4] - In 2015, a gas leak incident at a substation prompted the team to attempt a solution, but initial efforts resulted in 12 failed experiments over three days [3][4] - After extensive reflection and experimentation, the team discovered that understanding the pressure dynamics in the leakage area was crucial, leading to the successful sealing of leaks and the development of the "GIS component sealing space reconstruction technology" in 2021, which addresses six common SF6 leakage defects [4][5] Group 2: Development of Anti-Pollution Flashover Coating - The traditional anti-pollution coatings for insulators were inadequate, leading to significant power outages due to pollution flashover [5] - In 2015, a new coating was proposed to enhance the durability and cleanliness of external insulation devices, undergoing over 3000 trials over two years to achieve the desired properties [5][6] - The final product, a super-hydrophobic self-cleaning coating, achieved a contact angle greater than 150 degrees and a rolling angle of less than 10 degrees, filling an international gap in technology and winning the National Grid Technology Invention First Prize in 2024 [6] Group 3: Economic Impact and Recognition - Since 2015, the team has successfully sealed 163 SF6 leakage defects, ensuring the safe operation of 33 substations and generating economic benefits amounting to tens of millions [4][5] - The innovations not only address critical safety and environmental issues but also enhance the reputation of the State Grid Shandong Electric Power Research Institute as a leader in technological advancements within the industry [6]
