The embodiment of the utility model discloses current vortex power consumption damper for solve traditional rigidity damper or non - damping formula damper, rely on mechanical friction energy dissipation or use working fluid, have weeping and sealed scheduling problem easily, lead to its reliability and durability relatively poor, be difficult to the high -efficient technical problem who plays a role who lasts on requiring the long just difficult overhead line operational environment who maintains of fatigue life. The embodiment of the utility model provides an include: damper shell, quality piece, spring, connecting rod, conductor piece, magnet, cuboid quality piece is concretied to be run through at the inside montant of damper, the quality piece is by its upper and lower two spring -supported in middle parts, the connecting rod is articulated in vertical plane with the quality piece, there is the spout on the connecting rod, concreties and pass the spout at the inside horizontal pole of damper, conductor piece concreties in the connecting rod terminally, and the magnet sets up inside the damper, and conductor piece is located in the middle of the magnet for cutting magnetic induction line produces the current vortex.
