DEVICE FOR ICE REMOVAL FROM POWER TRANSMISSION LINE WIRE Russian patent published in 2014 - IPC H02G7/16 

FIELD: electricity.

SUBSTANCE: device for ice removal from power transmission line wire contains a housing, which is designed with a possibility of its mounting on a wire. Also it is provisioned with transportation means and ice removal devices. The transportation mean is designed as the container, filled with calcium carbide with a possibility of ensuring its contact with the humidified ice on a wire. To create the device moving force the jet force zero occurring from inflaming of acetylene, formed during chemical reaction as a result of interaction of calcium carbide with water. When ice is removed from a wire, heat is used, which is released as a result of chemical reaction and acetylene burning, for ignition of which in a combustor located inside a housing, the turbine driving wheel with a mill is installed on bearings. In the front part of the device the spring-loaded current-conducting elements are installed, for warming up of which the power supply designed as a toroidal current transformer is used.

EFFECT: increase of the device operation productivity and improvement of quality of ice removal.
