Wire with light guide function

Abstract

The invention relates to a wire with a light guide function. The wire comprises a conductor wire and an insulation outer layer. The insulation outer layer wraps the conductor wire, spiral grooves areformed in the insulation outer layer, light guide fibers are embedded in the spiral grooves, and transparent adhesion layers wrap the surfaces of the light guide fibers. The wire has the advantages that the light guide fibers are arranged in the spiral grooves and are firm and durable owing to winding fixing modes, accordingly, the wire can be advantageously subjected to irradiation from various angles, light emitting of the wire can be advantageously observed from various angles, visible light can be emitted by the integral wire in irradiation of color light transmitters, the time elapsed incable core alignment links can be shortened to a great extent when the wire is applied to manufacturing control cables, and the accuracy of the cable core alignment links can be improved.

Description

technical field [0001] The invention relates to a new type of electric wire, in particular to a wire with light-guiding function, which is a power wire mainly used in substation secondary equipment, instruments, and protection equipment wiring. Background technique [0002] In existing traditional substations, secondary specialties represented by relay protection, such as instrumentation, automation, communication, metering, etc., require a large number of secondary cables to realize equipment power supply and information transmission. Taking the relay protection profession as an example, there are at least a hundred secondary wires in each protective screen, and as many as nearly a thousand wires of the same style. In the work, the routing and arrangement of each cable must be clearly defined. In the original technology, the number tubes at both ends of the cable are used for identification. [0003] However, there are a large number of reasons in the substation that are ...

AI Technical Summary

Problems solved by technology

[0003] However, there are a large number of reasons in the substation that are wrongly marked, aged and oxidized, and the number tube itself has poor handwriting adhesion. It is easy to cause misjudgment of the connection between equipment and the direction of the secondary circuit, which affects the safe and stable operation of the substation and brings great difficulties to the secondary maintenance work

In the substation construction stage or overhaul technical transformation projects, control cables are often used. In the early stage, we need to check each wire of the cable. In this process, we need to use the multimeter to calibrate the line many times and then put on the number tube to mark it. Manpower, time, and error-prone
