Abstract:Diverse tree obstacles under overhead transmission lines pose significant challenges to the operation of power grids, which are critical for stable electricity supply. Once trees grow within the minimum safe distance specified for the voltage level of an overhead transmission line, they may cause short-circuit tripping of the transmission line, leading to power outages and disrupting its normal operation. In severe cases, this can result in widespread blackouts, grid collapse, or even forest fires. Tree obstacle management under overhead transmission lines has always been a pain point and difficult issue in transmission line maintenance.Traditional methods of clearing these obstacles rely on manual labor, which is time-consuming, labor-intensive, and carries high safety risks. To address these issues, a novel overhead transmission line corridor cleaning robot has been designed. This robot can move freely above the conductors of transmission lines and is capable of remote-controlled movement and automatic clearance of tree obstacles within the specified distance. The implementation of such a robot can significantly reduce the workload on personnel, lower safety risk factors, and enhance the efficiency of transmission line corridor cleaning operations.By adopting this innovative technology, it is expected to fundamentally improve the current situation of tree obstacle management under overhead transmission lines, providing strong support for the safe and stable operation of power grids.
