Novel rigid-collision-free spacer for power transmission line

Abstract

The invention discloses a novel rigid-collision-free spacer for a power transmission line. The novel rigid-collision-free spacer comprises a spacer framework, rotational joints and connecting wire clamps, wherein the connecting wire clamps are rotationally connected with the spacer framework through the corresponding rotational joints; each rotational joint is provided with a rotational joint rubber cushion; two limiting apparatuses are arranged on the upper surface of each rotational joint rubber cushion; each limiting apparatus comprises two rubber cushion lug bosses; a groove is formed between the two rubber cushion lug bosses on the same limiting apparatus; the shapes on one sides, close to rotational joint rubber cushion mounting holes, of the rubber cushion lug bosses are matched with those of the corresponding connecting wire clamps; each connecting wire clamp comprises a wire clamp body and a wire clamp head; the width of the tail part of the wire clamp body is smaller than that of the wire clamp body; and circular arc smooth transition is formed from the wire clamp body to the tail part. The spacer can be higher in mechanical bearing capability in a process of dramatic swinging and twisting of a divided conductor, so that the phenomena of tearing and deformation of the wire clamp body tail part can be avoided; and the anti-swinging performance of the spacer can be improved.

Description

technical field [0001] The invention relates to a protective fitting for an overhead power transmission line, in particular to a novel spacer bar for a power transmission line without rigid collision. Background technique [0002] In overhead transmission lines, spacer rods have the functions of preventing whiplash between split sub-conductors, suppressing wind vibration and sub-gap vibration, etc. The spacer mainly includes the frame main body and the connecting wire clip connected to the frame. The chuck of the connecting wire clip is used to hold the split sub-wire tightly, and through the limiting structure at the connection between the frame main body and the connecting wire clip, the wire clip Under the action of axial torsional force, it rotates at a certain angle along the tangential direction. [0003] The connection between the existing spacer frame and the wire clip mostly adopts a limit boss structure on the frame or a waist hole structure at the connection, so ...

Problems solved by technology

However, in the above-mentioned patent, the design of the structural size of the connecting wire clamp at the rotating joint is unreasonable, which weakens the mechanical load capacity that the wire clamp can bear. Break, causing great harm to line operation
