Design and Implementation of an Inspection Robot for Non-Destructive Testing of Aluminum Conductor Composite Core Wires

摘要

In order to detect the damage in the core of Aluminum Conductor Composite Core (ACCC) wires in the power grid, the design and implementation of an inspection robot based on non-destructive testing technology is introduced in this paper. First, the mechanical optimization design of the driving wheel is discussed. Second, the obstacle crossing capability of the inspection robot is analyzed by calculating the maximum climbing angle and the maximum surmountable obstacle size. Thus, the rationality of the structure design of the robot is verified. Finally, experiments were carried out on the experimental transmission lines and the overhead transmission lines in the grid. The results show that the robot can meet the requirements for in-situ mobile flaw detection of overhead ACCC wires.
