Anti-slip pre-twisted damping type spacer

Abstract

The invention provides an anti-slip pre-twisted damping type spacer which is good in anti-swing effect, capable of preventing a wire clamp from sliding on a wire and good in rotating effect at the same time. The anti-slip pre-twisted damping type spacer comprises a spacer body, an anti-slip pre-twisted wire clamp and a wire clamp pressing plate, wherein the wire clamp pressing plate comprises a wire clamp pressing plate body and a wire clamp pressing plate cover plate, and a threading hole formed by the wire clamp pressing plate body and the wire clamp pressing plate cover plate is internally provided a rotational damping wire clamp with a center hole. The anti-slip pre-twisted damping type spacer is characterized in that a stainless steel backing plate is arranged between the rotational damping wire clamp and the threading hole. According to the invention, the rotational damping wire clamp and the threading hole are provided with the stainless steel backing plate therebetween, the stainless steel backing plate is of a corrugated shape, so that the cylindrical inner wall and the damping wire clamp are enabled to have a certain elastic space therebetween, a wire clamp blocking condition does not occur when power transmission line swings and drives the rotational damping wire clamp to rotate, thereby enabling the rotational damping wire clamp to rotate smoothly, and thus enabling the power transmission line not to have a twisting phenomenon.

Description

technical field [0001] The invention relates to a spacer bar, in particular to a spacer bar with good anti-galling effect and capable of preventing wire clips from sliding on wires. Background technique [0002] In some areas, due to climate reasons, the wires of the power transmission circuit are often covered with ice. Due to the fixed connection between the spacer and the wires, the wires will dance greatly under a certain wind speed. The galloping of wires can easily cause short circuit, disconnection, collapse and even large-scale blackout of transmission lines, which seriously affects the safe and stable operation of the power grid and brings huge losses to the country. At present, the anti-dancing spacer is mainly divided into a single anti-dancing spacer for rotating wire clamps and a single anti-dancing spacer for fixed wire clips. Swipe up.

The galloping of wires can easily cause short circuit, disconnection, collapse and even large-scale blackout of transmission lines, which seriously affects the safe and stable operation of the power grid and brings huge losses to the country.

The patent "Name: A Spacer Swivel Clip, Application No.: 201020584294.4.X" discloses a swivel clip with better anti-galling effect, but in practice, due to the rotating clip inside the swivel clip and the swivel wire The inner wall of the clamp shell is in direct contact, and it will be greatly worn after long-term use, which will increase the internal friction of the rotary clamp, greatly reduce the rotational force, and even get stuck, thus greatly reducing the anti-galling of the spacer Ability
