Aluminum-coated carbon fiber conductor strain clamp

Abstract

The invention relates to an aluminum-coated carbon fiber conductor strain clamp, which is composed of a clamp body, a steel anchor, a compression pipe, a drainage plate and a drainage clamp, wherein the ratio of lengths of insertion to the compression pipe by an anchor rod and an aluminum-coated carbon fiber core is 1 to 2; as two end surfaces of the clamp body adopt a circular arc surface structure form, happening of a point discharge phenomenon is thus avoided; as the compression outer surface between the clamp body and the aluminum-coated carbon fiber conductor adopts a taper structure, stress concentration after compression is thus avoided; as the anchor rod of the steel anchor is uniformly provided with annular circular arc grooves, the compression pipe and the anchor rod and the anchor rod and the clamp body after compression can be closely fit, and the tension resistance is improved; as the drainage plate adopts a ring buckle and splint combination mode and the drainage plate and the drainage clamp are in double-sided contact, the conductive performance is better; and the compression part between the compression pipe and the aluminum-coated carbon fiber core adopts the taperstructure, stress concentration after compression to cause damages to the carbon fiber core can be avoided.

Description

technical field [0001] The invention relates to fittings for power transmission and distribution lines in the electric power industry, in particular to an aluminum-coated carbon fiber wire tension clamp. Background technique [0002] After retrieving relevant patent documents, no aluminum-clad carbon fiber wire tension clamp with the same structure as the present invention has been retrieved. The tension clamp is a power fitting that connects, fixes and tightens the wires on the tower. The existing transmission line conductors are generally steel-cored aluminum stranded wires. During the connection process, the steel core and the anchor of the tension clamp are crimped. During crimping, the steel core is under great pressure in the radial direction, and the force is uneven. For carbon fiber wires, the carbon fiber core is brittle, and it is easy to cause fracture under the condition of uneven force, which will cause the line to break and affect the entire wire. Line power s...

The tension clamp is a power fitting that connects, fixes and tightens the wires on the tower. The existing transmission line conductors are generally steel-cored aluminum stranded wires. During the connection process, the steel core and the anchor of the tension clamp are crimped. During crimping, the steel core is under great pressure in the radial direction, and the force is uneven. For carbon fiber wires, the carbon fiber core is brittle, and it is easy to cause breakage under the condition of uneven force, which will cause the line to break and affect the entire wire. Line power supply, although there is a strain clamp with a threaded connection structure for the anchor and the inner pipe, one is that the processing procedure is complicated, and the other is that the joint of the clamp is prone to heat during the use of the circuit, and the vibration of the transmission line causes the thread The connection is easy to loose, which poses a safety hazard to the transmission line, so it is necessary to design an aluminum-clad carbon fiber wire tension clamp to meet the actual needs
