Optical fiber composite overhead ground wire capable of melting ice

Abstract

The invention discloses an optical fiber composite overhead ground wire capable of melting ice. Multiple strands of rope-shaped wires with sections in a ball ring radiating shape are manufactured by an optical fiber cable 2, at least two strands of aluminum clad steel wires 1 and at least two strands of insulated wires 3 in a stranding and twisting mode, wherein the aluminum clad steel wires 1 surround the optical fiber cable 2, and the insulated wires 3 are uniformly wound on the surfaces of the aluminum clad steel wires 1. After the ground wire is covered by the ice, high voltage large currents can still be inputted, and temperature rising and ice melting are achieved. In addition, the optical fiber composite overhead ground wire has the advantages that other operations are not influenced when the ice is melted; the original anti-thunder function is kept; the ground wire is easy to manufacture, suitable for transforming an existing optical fiber composite overhead ground wire, capable of being wound directly, and quite convenient to use; the insulated wires not only are resistant to high temperature but also protect the ground wire against damage; labor intensity for deicing operation is greatly reduced; heat generated by the insulated wires is directly absorbed by the coated ice, and ice melting efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering and relates to an ice-melting optical fiber composite overhead ground wire. Background technique [0002] When encountering severe freezing disasters, the optical fiber composite overhead ground wire frequently breaks on the transmission line, causing interruption of power communication, and also causes a short circuit due to the residual optical fiber composite overhead ground wire falling on the conductor, which in turn causes line tripping accidents and affects normal power supply. Therefore, it is necessary to perform deicing treatment on the optical fiber composite overhead ground wire when the transmission line is covered with ice. In recent years, heating and deicing has gradually become the mainstream ice melting method for power grids. This heating treatment method is to melt the ice by applying a large flow of alternating current or a large flow of direct current to the c...

Problems solved by technology

However, since the optical fiber composite overhead ground wire is usually grounded tower by tower, it is not insulated from the ground, so it is impossible to apply voltage to heat and melt ice
