Core Viewpoint - The successful implementation of the "Little Flying Man" method for live working on the 750 kV Guowu II line marks a significant advancement in the mechanization and intelligence of live working in China's ultra-high voltage power grid, filling a technical gap in the industry [2][4]. Group 1: Technical Advancements - The "Little Flying Man" method utilizes a combination of drones and electric lifting devices to enhance safety and efficiency in live working environments, significantly reducing the time required for operations from 3-5 hours to under 1 hour [4][6]. - The method was applied at an elevation of 2106 meters, addressing challenges such as strong electric fields and strict safety distance requirements through extensive simulations and field validations [2][4]. Group 2: Operational Efficiency - The new working method has improved operational efficiency by over 200%, while also reducing the physical labor intensity for workers [6]. - The use of laser point cloud technology for 3D scanning and path planning has enabled precise deployment of insulated lifting ropes, creating a safe access route for workers [4][6]. Group 3: Industry Impact - Currently, there are 33 lines of 750 kV double-circuit towers in Gansu, totaling 2160 kilometers, and the successful application of this method will provide data and technical support for similar operations in the Northwest region [6]. - The advancement in live working techniques is expected to enhance the efficiency of renewable energy transmission between Gansu and Qinghai, improving inter-provincial energy complementarity [6].
