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 is attached flexible cable, passed through unit also fixed on a closed body, at end of which there is a load, 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 rolls with flanges and notches on outer surface of roller in form of teeth and changing distance between them, symmetric against pin axis, wherein at curved end of bar there are two parallel to each other plates with hole for dielectric sleeve and on rod there is a double-acting hydraulic cylinder with its rod through a dielectric sleeve is pivotally connected with plate.

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