Ice melting optical fiber composite overhead ground wire or ice melting ground wire, ice melting method and matched device

Abstract

The invention discloses an ice melting optical fiber composite overhead ground wire or ice melting ground wire, an ice melting method and a matched device. Insulated conductors in the ice melting optical fiber composite overhead ground wire or ice melting ground wire are electrified to be heated in various modes, and particularly the ice melting optical fiber composite overhead ground wire and an optical fiber temperature measuring device are cooperatively used to facilitate rapid deicing. According to the technical scheme of the invention, a power transmission system operates regularly, short circuit shunt and lightning stroke protection are achieved, and an effect of safe deicing is achieved; and the ice melting optical fiber composite overhead ground wire or ice melting ground wire of a power transmission line can be deiced even at an early icing period, a more serious result caused by the further expansion of ice disaster is avoided, and the loss in the ice disaster is greatly reduced.

Description

technical field [0001] The invention relates to a cable, in particular to an ice-melting optical fiber composite overhead ground wire or an ice-melting ground wire, an ice-melting method and supporting equipment. Background technique [0002] In high-voltage transmission lines, optical fiber composite overhead ground wires (OPGW) or ground wires are usually used as protective ground wires and optical communication lines, and steel-cored aluminum stranded wires or aluminum-clad steel stranded wires or aluminum alloy stranded wires are used as wires for power transmission. The OPGW or ground wire is erected on the top of the tower, and the wire is erected on the upper part of the tower below the OPGW or ground wire. Usually, the OPGW or ground wire is connected to the optical fiber at the lower part of the tower, and the OPGW or ground wire is grounded by using a down conductor. [0003] When the wires and OPGW or ground wires of the transmission line are frozen, in addition t...

AI Technical Summary

Problems solved by technology

[0005] This shows that above-mentioned existing OPGW or the on-line melting ice of ground wire obviously still have inconvenience and defect in use, and urgently need to be further improved

In order to solve the problem of online melting ice of OPGW or ground wire, the power department and related manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general OPGW or ground wire has no Appropriate structures can solve the above problems, which is clearly a problem that relevant industry players are eager to solve
