In traditional transmission line inspection

defect discovery mainly depends on manual experience

resulting in low inspection efficiency

insufficient coverage of key parts

and delayed identification of hidden hazards. To improve the active defect discovery capability of transmission lines

this paper proposes a UAV-based intelligent inspection technology. This technology optimizes standardized operation procedures

constructs typical defect inspection scenarios

and formulates differentiated inspection strategies. It enables active inspection of conductors

ground wires

insulators

fittings

and line corridor hazards. Based on field application

this paper analyzes the technology in terms of operation efficiency and defect identification performance

and verifies its practicality and engineering application value.
