Design of a Flying Robot for Repairing Broken Strands of Transmission Line Conductors

To solve the high-risk and high-strength problem of repairing broken strands in transmission lines, a flying robot for repairing broken strands in transmission lines was designed and developed based on unmanned air vehicle (UAV) technology. First, the overall structure and functional requirements of the flying robot are analyzed based on the characteristics of the circuit and broken strands; second, the main mechanisms of flying, walking and repairing of the flying robot are designed, and the control process and system of the flying robot are studied; finally, the arc current interference characteristics of the robot during the potential transfer is studied, the electromagnetic protection design idea is proposed, and the test is carried out in the simulated field to verify the functions of the device. The results show that the flying robot proposed in this paper meets the field requirements.
