Embodiment Construction

[0035] Below in conjunction with example the present invention is described in detail.

[0036] The invention provides a splicing fitting and splicing method applied to an attached graphene nano material wire.

[0037] The structure of the attached graphene nanomaterial wire is as follows figure 1 As shown, the wire includes an inner layer 1 and an outer layer 2. The inner layer 1 is a circular tube of carbon fiber composite material, which is mainly used as a load bearing. Form a regular tubular structure. The outer layer 2 is a uniformly attached graphene nanomaterial sheet, which is arranged on the periphery of the inner layer. The graphene nanomaterial sheet has an arc-shaped structure and is the conductive part of the overhead transmission line conductor.

[0038] The connecting hardware includes a carbon fiber crimping connecting tube 3 and a graphene film connecting sleeve 4, which are respectively used for connecting the inner layer 1 and the outer layer 2.

Abstract

The invention provides a graphene nanomaterial wire splicing fitting and a splicing method, solves the difficult problems in attached graphene nanomaterial wire construction, and provides a technical support for the engineering application of graphene nanomaterial wires. The splicing fitting comprises a carbon fiber crimping splicing pipe and a graphene film splicing sleeve, wherein the carbon fiber crimping splicing pipe consists of a columnar matrix with an O-shaped cross section, and the inner and outer surfaces of the matrix are of a smooth structure; and the graphene film splicing sleeve consists of a fan-shaped sheet with an arc-shaped cross section, and the inner and outer surfaces of the fan-shaped sheet are of a smooth structure. According to the splicing method provided by the invention, two wires to be spliced are connected by the splicing fitting by a hydraulic method and a hot air method, and a splicing part simultaneously ensures the transferring of tension and electrical loads.

Description

technical field [0001] The invention belongs to the technical field of connecting fittings for wires used in power transmission lines, and in particular relates to a connecting fitting for wires made of graphene nanomaterials and a connecting method. Background technique [0002] The wire splicing tube is used at the two terminals of the overhead transmission line wire. In addition to bearing all the tension of the wire, it also conducts current as a conductor and is an important fitting in the transmission line. [0003] The UHV project aims to build an "environmentally friendly" project, comprehensively optimizes the design of the project, and strictly ensures that the electric field, magnetic field, audible noise and radio interference levels meet the standard requirements. For this reason, if the design uses ordinary wires, it is necessary to increase the cross-section of the wires and increase the number of split wires, which will inevitably increase the use of wires an...
