Core Viewpoint - The application of drone technology in power transmission inspection has significantly improved efficiency and safety, transitioning from manual to automated processes in the industry [1][3][4]. Group 1: Drone Technology Development - The team began exploring drone inspections in 2013, facing challenges such as complex structures and operational difficulties, initially achieving only 3-5 tower inspections per day [3]. - After several years of development, the drone inspection capabilities improved, allowing for the completion of inspections of 10 towers in half an hour, replacing manual inspections [3]. Group 2: Innovations in Drone Inspection - The team developed three key innovations: an autonomous navigation system for drones, a multi-spectral imaging system for defect detection, and an intelligent analysis system that achieves over 95% accuracy in identifying defects from inspection images [3][4]. - In 2021, the team deployed the first drone nest for autonomous inspections, enabling remote control of drones over distances of up to 4 kilometers without human intervention [4]. Group 3: Achievements and Future Prospects - By 2023, the team established 568 drone nests across the province, creating a collaborative inspection demonstration area and normalizing the use of drone inspections [4]. - The evolution of drone inspections has progressed from manual control (1.0) to autonomous inspections (2.0) and finally to collaborative drone nests (3.0), marking a significant transformation in the industry [4].

Core Viewpoint - The company is proactively ensuring stable electricity supply during the upcoming May Day holiday by utilizing drone technology for detailed inspections of power lines and equipment [1][4]. Group 1: Drone Inspection Implementation - The drone inspections cover important transmission lines, substations, and key equipment within the jurisdiction [4]. - Compared to traditional manual inspections, drones offer advantages such as flexibility, comprehensive perspectives, and the ability to reach difficult terrains, allowing for high-definition imaging and infrared temperature measurement [4]. Group 2: Detection and Response to Hazards - During the inspection of the 10 kV Duxi line, the drone detected an abnormal temperature increase in a tension clamp, which was later confirmed to be due to poor contact [4]. - The company quickly organized a repair team to replace the problematic clamp, successfully eliminating the safety hazard [4]. - To date, the company has completed inspections of 23 major lines and identified and addressed 3 hazards, ensuring the equipment is "healthy" for operation [4]. Group 3: Emergency Preparedness and Future Plans - The company has developed a detailed emergency response plan and assigned personnel for 24-hour monitoring to ensure quick and efficient handling of any unexpected situations [4]. - Moving forward, the company plans to increase inspection efforts and leverage the advantages of drone technology to create a safe, stable, and reliable electricity environment for users during the holiday [4].
