Abstract

The invention provides a triggering type anti-galloping device and a wire galloping monitoring device and method. The triggering type anti-galloping device comprises a pendulum bob shell (6), a triggering type sensor (5) arranged in the pendulum bob shell (6), a first spring (7) and a second spring (8). The triggering type sensor (5) is connected with the inner wall of the pendulum bob shell (6) through the first spring (7) and the second spring (8). The triggering type sensor (5) is used to collect the position coding information of the wire. The linear rigidity and the cubic rigidity of thependulum bob are determined on the basis of the nonlinear energy groove theory, the anti-galloping effect limitation is small, the anti-galloping effect is good, and conductor galloping monitoring canbe achieved. The galloping characteristic of the conductor length body is effectively changed, and the easy galloping during low wind speed and thin icing is avoided; according to the conductor galloping monitoring device provided by the invention, the conductor galloping condition is monitored through interaction between the plurality of triggering type anti-galloping devices and the relay system, and a basis is provided for disaster prevention and reduction.

Description

technical field [0001] The invention relates to the technical field of power grid disaster prevention and reduction, in particular to a trigger-type dance prevention device, a wire dance monitoring device and a method. Background technique [0002] The low-frequency, large-amplitude self-excited vibration phenomenon of overhead conductors with uneven ice coating along the circumferential direction under the action of lateral wind is called conductor galloping. When the wire dances, one, two or three antinode standing waves or traveling waves will be formed in a wire. The wire mainly moves vertically, sometimes in an elliptical motion. The long axis of the ellipse is in the vertical direction or deviates from the vertical direction. Sometimes it is accompanied by twisting of the wire. The frequency of vertical vibration is about 0.1-1Hz, and the amplitude is between tens of centimeters and several meters. Serious conductor galloping is an antinode vibration in the long-gaug...
