FIELD: power engineering. SUBSTANCE: power transmission line with pendulum deicing installation has supporting structures, wires, and deicing installation in the form of conductor-mounted water-repellant and cleaning container operating in axial direction and provided with seating slit and holes in side walls for mechanical crushing and removal of deposited atmospheric ice from conductor; novelty is that water-repellant and cleaning container performs oscillatory, and not revolving, motion on conductor due to replacement of blades forming air turbine by two relatively perpendicular blades fixed relative to container; one of blade affords displacement of water-repellant and cleaning container over conductor from one end of power transmission line span to other in case of change in bearing of apparent wind and other blade mounted in plane longitudinal in respect to conductor with offset relative to container to displace its center of gravity, provides for oscillatory movement of container due to interaction of two variable forces, one aerodynamic force deflecting blade from equilibrium position in case of stronger wind, and other one is blade gravity force tending to return blade to initial position when wind goes down. EFFECT: improved economic efficiency of deicing installation due to its better reliability and reduced cost. 1 dwg |
