MOBILE APPARATUS FOR REMOVAL OF ICE FROM POWER TRANSMISSION LINE WIRE Russian patent published in 2016 - IPC H02G7/16 

FIELD: electric power engineering.

SUBSTANCE: use: in electric power engineering. Mobile plant for removing ice with power transmission line wire includes: caterpillar transport facility for maintenance of power transmission line with a closed body, on which pivoted rod to turn about hinge in vertical plane, and to other end of rod through tension spring is attached flexible cable, passed through unit also fixed on a closed body with its end through lever is coupled with hydraulic cylinder, device for ice removal from a wire power transmission line containing plate with fixed: on one side pin, perpendicular to welded to middle of plate, and on other side, two rollers with possibility of rotation and changing distance between them, symmetrically located from axis of pin on curved rod end there are two parallel to each other plates with hole for dielectric bushing, and double-acting hydraulic cylinder is installed on rod with its rod through a dielectric sleeve is pivotally connected with plate end of bar, in area of wire icing, a hose with a tip and piezoelectric element for ignition of combustible gas.

EFFECT: technical result is increasing efficiency of removal of ice from cables and overhead power lines.
