Pipe bus flexing line clamp

Abstract

The invention relates to a wire clamp for a generatrix of a connecting pipe, consisting of a pair of bodies provided with a pipe chase, a cover board connected with the bodies and a plurality of elastic stranded wires connected with the bodies, wherein, the elastic stranded wires between the bodies are arranged along the axial cross section of the body in an arc and sector shape, the distance of each stranded wire core from the axial line of the pipe chase of the body is constant. In the invention, a plurality of metal stranded wires are arranged on the radial cross section of the body in a sector shape and the distance of each stranded wire core from the axial line of the pipe chase of the body is constant; therefore, each stranded wire is positioned at the same equipotential surface, thereby preventing the stranded wires from heating; a plurality of cover boards are arranged to make the connection reliable and are respectively connected with bodies. The wire clamp has low cost, good effect and long service life.

Description

technical field [0001] The invention relates to an electric power fitting, in particular to a clamp for connecting pipe busbars. Background technique [0002] With the development of the economy, the power demand in the developed areas of the processing industry is increasing. In order to meet the requirements of large-scale power transmission, the power transmission line adopts a tube bus that can transmit large currents. The corona effect has always existed in power transmission. Under the condition of certain weather conditions, voltage, phase distance and arrangement, the corona critical voltage is mainly affected by the radius of the wire and the surface roughness coefficient, that is, the larger the radius of the wire, the smoother the surface , the corona effect is smaller. Therefore, the use of large-diameter aluminum alloy tubular busbars is an effective measure to reduce the level of corona radio interference. In order to realize long-distance transmission, multi...

AI Technical Summary

Problems solved by technology

At present, multiple steel / aluminum core stranded wires of the tube bus clip are arranged in parallel and equidistant, and the two outer stranded wires will generate heat during use. In the long-term use, the body of the clamp body will have mechanical properties due to uneven temperature. changes, reduce the service life, and in severe cases, such as sudden breakage, will also cause power failure
