Reinforced type lead wire damping spacer

Abstract

The invention relates to a reinforced type lead wire damping spacer comprising an upper frame, a lower frame, four wire clamp bodies and a cover plate, wherein one end of each wire clamp body is internally provided with a cross shaft sleeve, the wire clamp bodies, the upper frame and the lower frame are fixedly connected into a whole, the other ends of the wire clamp bodies are matched with the cover plate into a whole through hinge pins, and the wire clamp bodies and the cover plate are internally provided with rubber pads; a plurality of groups of upper frame concave tables and lower frame concave tables which are mutually matched are arranged between the upper frame and the lower frame, wherein one end of each upper frame concave table is fixedly connected with the upper frame, one end of the lower frame concave table is fixedly connected with the lower frame, and the other ends of the upper frame concave tables are matched with the other ends of the lower frame concave tables in a convex-concave inserting way. The invention enhances the anti-wind and anti-ice capability of an electric fence, reduces the loss caused by snow storm, ensures the normal operation of circuits and enhances the safety and the stability of the circuits.

Description

technical field [0001] The invention relates to the field of power transmission lines, in particular to a reinforced wire damping spacer. Background technique [0002] During January-February 2008, extremely rare rain, snow and freezing disasters broke out in China, resulting in the paralysis of the 500 kV transmission line network in Guizhou, Hunan, Zhejiang and other provinces and cities. In this disaster, the direct loss of China Southern Power Grid Corporation was 13.43 billion yuan, and the direct loss of State Grid Corporation was 10.4 billion yuan. Analyzing the reasons, the main reason is that the thickness of the grid wires is generally 40 mm to 50 mm, and some of the maximum thicknesses have reached 70 mm to 80 mm, far exceeding the design standard value. When the line fittings are thickened with ice, only subjected to one-sided wind pressure, and a sub-conductor is under asymmetrical force, the conventional line fittings are prone to distortion and deformation or...

Problems solved by technology

When the line fittings are thickened with ice, only subjected to one-sided wind pressure, and a sub-conductor is asymmetrically stressed, the conventional line fittings are prone to distortion, deformation or even overall fracture and damage.
