LIMITATION METHOD OF SINGLE WIRES GALLOPING INTENSITY OF OVERHEAD TRANSMISSION LINE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC H02G7/14 

FIELD: electricity.

SUBSTANCE: method includes in suspending of the pendulum dampers (3) and the pendulum stabiliser dampers (4) at the wire (1) of the span (2). The pendulum dampers (3) are fixed to the wire (1) in the horizontal plane near the ends (8, 9) of the span (2) or from the attachment points (10) of the pendulum stabiliser dampers (4). The pendulum dampers (3) are installed in pairs in staggered state in such a way, that one pair of the pendulum dampers (3) is to the left from the wire (1), and the next pair of the pendulum dampers (3) is to the right from the wire (1). The number of pendulum stabilisers (4) is chosen from L/150 to L/250, where L is the line span length (2) in meters, and its moment of inertia exceeds the moment of inertia of the pendulum dampers (3). The pendulum dampers and the pendulum stabiliser dampers consist of the wire spirals set, bent together in the form of the letter Ω and winding by its ends on the wire.

EFFECT: efficiency increase of the wires vibration oscillations suppression in the wide frequency range.
