Problems solved by technology

However, the spacer bar prevents the wire from being freely twisted, and it is easy to form uneven icing, which greatly increases the probability of galloping of the split wire compared with the conventional single wire

Embodiment 1

[0028] The anti-galling damping spacer provided in the present invention includes: a rotatable wire clamp 1 , an ordinary wire clamp 2 , and a double-plate body frame 3 . The device includes three rotatable wire clamps 1 and three common wire clamps 2, which are evenly distributed on the six ends of the hexagonal body frame 3. The rotatable line clamp 1 is located on the hexagonal end point on the windward side, and the common line clamp 2 is located on the hexagonal end point on the leeward side. The connection part between the rotatable wire clip 1 and the body frame 3 is the same as the connection part between the common wire clip 2 and the body frame 3 .

[0029] Compared with the existing spacer, the anti-galling damping spacer provided by the present invention does not change the connection form between the wire clip and the body frame, but realizes the rotation of the wire through the rotatable wire clip 1 . Therefore, no special tools are required during installation,...

Embodiment 2

[0034] The anti-flapping damping spacer provided in this embodiment includes: a rotatable wire clamp 1 and a double-plate body frame 2 . The device includes four rotatable clamps 1, which are evenly distributed on the four ends of the regular quadrilateral body frame 2.

[0035] The structure of the rotatable wire clamp in this embodiment is the same as that in Embodiment 1, and will not be described here again. Compared with the first embodiment, all the clamps in this embodiment are rotatable clamps, which can better suppress the occurrence of galloping.

[0036] It should be noted that this embodiment does not limit the scope of application of the anti-galling damping spacer rods disclosed in the present invention, and any two-split or above phase-split wires can be used. Secondly, this embodiment also does not limit the number and installation positions of the ordinary wire clips and the rotatable wire clips in the actual application process, as long as the installed spac...

Abstract

The embodiment of the invention discloses a bouncing-prevention damping spacing rod, comprising a body frame and a wire clamp connected on the body frame; the wire clamp at least comprises a rotation wire clamp, the rotation wire clamp comprises an outer wire clamp connected with the body frame and an inner wire clamp which is wrapped in the outer wire clamp and is provided with chloroprene rubber at inner side, the inner wire clamp is axially fixed in the outer wire clamp and rotates freely by taking the central axis of the outer wire clamp as the shaft; the bouncing-prevention damping spacing rod in the invention has the advantages that: the rotation inner wire clamp is adopted to be axially fixed in the outer wire clamp, a hoop free-rotation structure leads a lead wire to rotate freely, so as to prevent bouncing; in addition, the rotation part is hard to break down owning to effect of the environment, so as to ensure the working reliability of the damping spacing rod; the connecting type of the wire clamp and the frame is consistent to the common type thereof at home, therefore, no special tool is needed for installation.

Description

technical field [0001] The invention relates to power transmission line equipment, in particular to an anti-galling damping spacer. Background technique [0002] Transmission line conductor galloping refers to the large-scale low-frequency vibration phenomenon caused by the transmission line under certain climatic conditions, the ice-coated conductor is asymmetrically covered with ice and subjected to transverse wind. Galloping of transmission line conductors is an important factor that threatens the safe operation of high-voltage transmission lines. Galloping damages the transmission line, causing phase-to-phase flash tripping and arc burns. Due to galloping, the wire itself, connecting parts, and iron towers all bear large dynamic loads. When the load exceeds a certain limit, the wires, iron towers, insulator strings and There will be serious damage to the connected parts. There have been large-scale power outages in various parts of our country caused by short-circuit o...
