Description

technical field [0001] The invention belongs to the field of electronic technology. Background technique [0002] At present, in the transmission of outdoor high-voltage lines, in order to ensure safety and stability, and prevent short circuits and open circuits, it is not desirable to have conductors in the transmission process. Once metal or other electrical conductors are present, there is danger. One of the more common phenomena is that there will be trees growing under the outdoor high-voltage lines, and once the overgrown branches are connected between the wires, they will inevitably become a safety hazard. Therefore, security inspectors need to regularly conduct safety inspections on high-voltage lines to ensure the normal operation of the power system. When the security inspector conducts safety inspections outdoors, the general method is to remove the branches that pose a safety hazard to the wires with the tools they carry. When encountering relatively high branc...
