Abstract: A power line de-icing apparatus which is installed onto a power line without the need for disconnecting the power line. A temperature sensor and an ice sensor on the apparatus automatically activate the de-icing mode of operation. An internal motor and drive wheel move the apparatus along the power line in both directions, one direction at a time. Heaters and chisels on the apparatus remove any ice on the power line in one direction at a time. Power for the apparatus is generated from the electrical power carried by the power line using transformers. Proximity sensors on the apparatus detect stopping devices placed on the power line to stop the motion of the apparatus.

Abstract: A power line de-icing apparatus that incorporates both thermal and mechanical means to remove various forms of accumulated ice or wet snow from power lines. The apparatus uses a minimum amount of energy to first de-bond and then break off ice from the power line; using far less power than required to fully melt ice. The apparatus operates autonomously, activating heating and chisel mechanisms, and moving between power line support towers in response to both temperature and ice sensor inputs. This operation is repeated in both directions along the power line as long as icing continues to activate the sensors; removing ice more quickly than it can accumulate and thereby preventing mechanical or electrical damage to the power lines and supporting towers. The apparatus is self contained and powered inductively from the power line. It is installed onto the power line without the need for disconnecting the power line.
