FIELD: power engineering.
SUBSTANCE: area of application: in the field of electric power engineering for marking wires and ground wearers of overhead power lines (OHL) in areas of small aircraft flights. Warning sphere comprises two detachable semi-spheres, hinged together and equipped with clamping jaws with holes for the passage of a wire or a ground wearer of an overhead power line, formed when the semi-spheres are closed together. Springs pulling the semi-spheres together are installed inside the warning sphere. In order to ensure the possibility of detaching the springs from one of the semi-spheres, fasteners are installed at the ends of the springs, in the form of hitches, the rotary parts whereof are connected by rods with the ring with a pull bar and a stop, installed in the upper part of the warning sphere. According to the method, an unmanned aerial vehicle flies close to the warning sphere, hooks the ring with the grip installed on the body of the unmanned aerial vehicle, and pulls the ring, moving from the sphere upwards, causing the fasteners installed at the ends of the springs to open, the semi-spheres of the warning sphere to spread open, and the warning sphere to be removed from the wire or ground wearer of the OHL.
EFFECT: provided possibility of remotely dismantling a warning sphere without disconnecting the OHL while reducing the trauma rate and the labour consumption.
