A release type suspension clamp

Abstract

The invention provides a release type suspension clamp. The cross section of a suspension clamp body is triangular, openings are formed in the two ends of the bottom surface of the suspension clamp body, and blind holes are vertically formed, symmetrical with the longitudinal central axis of the bottom surface of the suspension clamp body, on the transverse central axis of the bottom surface of the suspension clamp body. The release type suspension clamp is characterized in that the suspension clamp comprises a base and a cover plate which is arranged on the base, through holes corresponding to the bottom surface of the suspension clamp body are formed in the base, and the base and the suspension clamp body are fixedly connected through screws arranged in the blind holes and the through holes. Compared with the prior art, the release type suspension clamp has the advantages that longitudinal unbalance tension of a wire of a tower is reduced by sliding the suspension clamp and the wire, a tangent suspension tower is protected from damage, and therefore safe and reliable operation of a transmission line is guaranteed; the release type suspension clamp is simple and light in structure, streamline in appearance, capable of meeting the requirement of line projects, and suitable for being massively popularized and used, and high practicability and remarkable economic benefits and social benefits are achieved.

Description

technical field [0001] The invention relates to a suspension wire clamp, in particular to a release type suspension wire clamp which prevents damage to the linear tower of a power transmission line due to excessive longitudinal unbalanced tension of a wire caused by uneven ice coating. Background technique [0002] In recent years, with the continuous acceleration of China's electric power development, China's power grid has also developed rapidly, the operating voltage level of the power grid system has continued to increase, and the network scale has also continued to expand. At present, power grid construction has become the main direction of my country's electric power construction. By 2020, a strong smart grid will be fully built, and the goal of building a world-class power grid will be initially realized. [0003] At the beginning of 2005, a total of 24 towers of 500kV transmission lines in Hunan Province suffered tower collapse accidents caused by ice-covered overloa...

AI Technical Summary

Problems solved by technology

The grip force of the suspension clamp on the conductor comes from the friction between the clamp and the conductor, and it is difficult to achieve precise control of the grip force. In the actual line tower collapse accident, the suspension clamp did not slip, and the longitudinal tension of the conductor was unbalanced before the tower collapse unable to release
