A kind of anti-vibration fitting for wide-band suppression of breeze vibration of transmission line

Abstract

An aero-vibration broad band inhibition anti-vibration hardware fitting for a power transmission line comprises a connection unit and quality units, wherein the connection unit is connected by an internal wire clamp; the quality units are connected to both ends of the connection unit; the connection unit is a connection steel strand rope; the quality units are two U-shaped steel strand ropes of which both ends are separately and fixedly connected with a hammerhead; the hammerhead ends of the two U-shaped steel strand ropes of which both the ends are separately and fixedly connected with the hammerhead are reverse; both ends of the connection steel strand rope are separately connected to the middles of the U-shaped steel strand ropes; two hammerheads separately and fixedly connected with both the ends of the U-shaped steel strand ropes are unequal in mass and are horizontally arranged, and the connection steel strand rope and the U-shaped steel strand ropes are different. The aero-vibration broad band inhibition anti-vibration hardware fitting for the power transmission line has the advantages of reasonable structure, easiness for manufacturing, reliability for use and wide spectral range of inhibiting vibration of a wire, and can be widely used for aero-vibration wind resistance of the power transmission line so as to implement safety operation and use of the power transmission line and prolong the service life of the power transmission line.

Description

technical field [0001] The invention relates to a broad-band suppression and anti-vibration fitting for breeze vibration of a power transmission line. [0002] Background technique: [0003] Under the action of the wind, the transmission line is in a state of vibration all the time. Since the cross section of the ground wire, the height of the suspension point and the span of the UHV transmission line project are larger than those of the ordinary line, the vibration of the UHV transmission line under the action of the wind is very serious, which greatly threatens the UHV transmission line. safe operation of the line. According to the difference in frequency and amplitude, the vibration of UHV transmission lines can be roughly divided into three types: high-frequency and slight-amplitude breeze vibration, intermediate-frequency and medium-amplitude wake galloping, and low-frequency and large-scale galloping. All three kinds of vibrations will cause damage to the transmission...
