Abstract: This paper addresses the issues of fixed installation blind spots and the risks associated with manual detection in existing transmission line sag detection devices. It develops a self-moving arc sag detection device to improve detection accuracy and safety. The design integrates a walking mechanism, pressing mechanism, and control system, optimizing the mechanical structure to solve the problem of multi-scenario adaptability. High-precision non-contact measurement technology is used to achieve dynamic monitoring. The developed mechanism is capable of climbing slopes up to 30˚, with a positioning accuracy of ±2 mm and environmental adaptability ranging from −20˚C to 50˚C. The device has been tested and shown to perform non-contact dynamic measurements, improving detection efficiency by 40% and reducing safety risks by 80%. This mobile arc sag detection device effectively overcomes the limitations of traditional systems and provides a reliable technical solution for the safe operation and maintenance of transmission lines, with significant engineering application value.
