Connecting hardware assembly and connecting method for composite material core high-voltage aluminum stranded wire

Abstract

The invention provides a connection hardware assembly for a composite material wire core high-voltage aluminum stranded wire and a connection method. The connection hardware assembly comprises at least one connection assembly body. The connection assembly body comprises an inner steel pipe, an outer sleeve steel pipe, a steel end socket and a steel plug. A containing cavity capable of containing a composite material core bar connecting end is arranged in the inner steel pipe in the axial direction. The containing cavity is formed by at least one clamping cavity section, wherein the clamping cavity sections are connected in sequence and communicated, each clamping cavity section is in the necking-down shape and is decreased progressively in the axial direction, and the composite material core bar is clamped in the necking-down end of each clamping cavity section. The inner steel pipe is sleeved with the outer sleeve steel pipe. The steel end socket is fixedly arranged at the end, facing the composite material core bar, of the outer sleeve steel pipe. A through hole is formed in the center of the steel end socket. The through hole is communicated with the containing cavity of the inner steel pipe. The steel plug is plugged to the end, not facing the composite material core bar, of the outer sleeve steel pipe and the inner steel pipe. According to the connection hardware assembly for the composite material wire core high-voltage aluminum stranded wire and the connection method, the high-voltage aluminum stranded wire terminal connection strength and the wire abutting connection strength are ensured, installation is easy, and the connection stability is high.

Description

technical field [0001] The present invention relates to a connection fitting assembly used in the installation of power transmission lines, more specifically, to a terminal conductor, wire and wire butt joint for high-voltage aluminum stranded wire with a composite material core used in the installation of power transmission lines. The connection fittings components and connection methods. Background technique [0002] At present, the connecting components of the existing transmission lines usually use tension fittings and splicing fittings components, and these components are widely used in traditional high-voltage and large-capacity transmission lines. The traditional power transmission cable is aluminum steel core stranded wire (ACSR). The steel anchor used to connect the tension fittings and the connecting fittings at the terminal and the steel core of the stranded wire are all metal materials, which belong to the connection of the same material. [0003] However, with ...

Problems solved by technology

[0004] However, due to the material and process problems of the existing composite material wire core connection components, the stress generated by the connection of two different materials and the shear force of the port have not been effectively solved. Technical problems of terminal connection and wire docking

At the same time, due to the complexity of the installation, the stability of the connection cannot be effectively guaranteed
