Jointing metal tool and jointing method for composite graphene nano material wires

Abstract

The invention provides a jointing metal tool and a jointing method for composite graphene nano material wires, and the jointing metal tool and the jointing method are used for solving the difficulty in composite graphene nano material wire construction and providing technical support for the engineering application of the composite graphene nano material wires. The jointing metal tool provided by the invention comprises a graphene jointing pipe and an aluminum sleeve, wherein the graphene jointing pipe is composed of a cylindrical base body with an O-shaped cross section; the internal and external surfaces of the base body are provided with smooth structures; the aluminum sleeve is a round pipe with air vents; the cross-sectional area of the round pipe is gradually increased and then decreased along the length direction of the aluminum sleeve; and the internal and external surfaces of the round pipe are provided with smooth structures. According to the jointing method provided by the invention, a hydraulic method and a hot gas method are utilized, two to-be-jointed wires are connected by virtue of the jointing metal tool, and the joint part can transfer electric load while ensuring tension force transfer.

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 composite graphene nanomaterial wire connecting fitting 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 and bu...
