Core Insights - The article highlights the use of industrial-grade drones for inspecting high-voltage transmission lines in Shanxi, marking a significant advancement in the maintenance of the power grid [2][3]. Group 1: Technology and Innovation - The State Grid Linfen Power Supply Company has implemented a new "X-ray + simulated line flight" technology for non-destructive testing of transmission lines, representing a shift to a three-dimensional, non-destructive inspection phase [2]. - The X-ray emission system functions like an experienced "line doctor," generating digital images of internal structures and identifying hidden defects such as broken strands, corrosion, and cracks with centimeter-level precision [2]. - The "simulated line flight" allows drones to autonomously and accurately follow the transmission line, maintaining optimal observation and operational distances, transforming drones from manual-operated "cameras" to autonomous "smart robots" capable of complex tasks [3]. Group 2: Operational Efficiency - Previously, inspecting internal conditions of lines was hazardous and time-consuming, often requiring workers to climb high towers or use heavy machinery, which posed significant risks and missed many hidden defects [5]. - The new drone technology has fundamentally changed inspection processes, reducing high-altitude operational risks by over 90% and increasing defect detection rates by 40% [5]. - The technology represents a transition from human-based to technology-based safety measures, with plans to integrate AI for intelligent image diagnosis and automatic defect identification in the future [5].
