Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. On the basis of the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without any creative effort belong to the protection scope of the present application.

In a first aspect, referring to fig. 1, 2 and 3, an embodiment of the present application provides an electrical wire including an optical fiber 1, a detecting member, a sheath 2 and a core 3;

the wire sheath 2 wraps the wire core 3;

the optical fiber 1 is arranged in the cable sheath 2, the detection piece is arranged outside the cable sheath 2, and the detection piece detects the luminous flux of the optical fiber 1 and outputs a detection result.

Specifically, the material of the sheath 2 may be a plastic material such as polyvinyl chloride, polyethylene, polyperfluoroethylpropylene, polyolefin, or a rubber material such as chlorinated polyethylene, chlorosulfonated polyethylene, chloroprene rubber, silicone rubber, or the like. The main function of the wire sheath 2 wrapping the wire core 3 is to protect the wire core 3 from mechanical damage and chemical corrosion, and the mechanical strength of the wire can be enhanced, so that the tensile and compression resistant effects are achieved.

The material of the wire core 3 can be a copper core or an aluminum core. The number of the wire cores 3 can be a single wire or a plurality of wires.

The optical fiber 1, also called an optical fiber, is a fiber made of glass or plastic and serves as a light transmission means. The optical fiber 1 is disposed in the sheath 2, an emitting device such as a Light Emitting Diode (LED) or a laser may be disposed at one end of the optical fiber 1 to transmit light pulses to the optical fiber 1, and a detecting member such as a photosensor may be disposed at the other end of the optical fiber 1 to detect light flux passing through the optical fiber 1. The optical fiber 1 is arranged in the sheath 2, when the wire sheath 2 is damaged by external force such as sharp edge abrasion and high-temperature ablation, the optical fiber 1 in the sheath 2 is also damaged, and the light flux in the optical fiber 1 is reduced or broken sharply. When the wire is bent, as shown in fig. 4, the optical fiber 1 is deformed or even broken by the tearing stress applied to the sheath 2, and the light flux in the optical fiber 1 is also sharply reduced or broken. The detection piece can compare the luminous flux that detects with the luminous flux in the optic fibre 1 under the normal condition, when the luminous flux that detects is not in the scope of normal luminous flux, can report to the police through flash of light or bee calling organ, reminds security personnel electric wire to have the potential safety hazard to and handle this potential safety hazard in time, avoid the incident to take place.

In the embodiment of the present application, the optical fiber 1 is disposed in the sheath 2, the detecting element is disposed outside the sheath 2, the detecting element is used to detect the luminous flux of the optical fiber 1, and the detection result is output. The maintainer can judge the line skin 2 of electric wire according to the testing result of output and have or not damaged trouble to in time handle when the line skin 2 of electric wire is damaged, reduce the risk of catching fire, improve the security.

Optionally, a distance between the optical fiber 1 and the outer skin of the sheath 2 is smaller than a distance between the optical fiber 1 and the inner skin of the sheath 2.

It should be understood that, the closer the optical fiber 1 is to the outer skin of the wire sheath 2, the more sensitive the optical fiber 1 reacts to the damage of the outer skin of the wire sheath 2, and the sensitivity of the fault detection of whether the wire sheath 2 of the electric wire is damaged or not can be further improved, so that the fire risk is further reduced, and the safety is improved.

Alternatively, referring to fig. 3, the extending direction of the optical fiber 1 is parallel to the axial direction of the electric wire.

It should be understood that the optical fiber 1 extends from the first end of the wire to the second end of the wire, and the extending direction of the optical fiber 1 may be parallel to the axial direction of the wire or not. The optical fiber 1 may extend linearly or may extend in a curved line. When the extending direction of the optical fiber 1 is parallel to the axial direction of the electric wire, the length of the optical fiber 1 is shortest, and the material cost can be saved.

Optionally, referring to fig. 2, the number of the optical fibers 1 is two, and the two optical fibers 1 are arranged oppositely.

It is to be understood that the optical fiber 1 disposed in the sheath 2 may be one or more. If the optical fiber 1 is only one, the optical fiber 1 is arranged in a first area in the cable sheath 2, when the cable sheath 2 is damaged in a second area opposite to the first area, the light flux of the optical fiber 1 arranged in the first area may not change due to the fact that the position is far away from the first area, at the moment, potential safety hazards exist, but the detection piece may not detect abnormality, the damage of the cable sheath 2 cannot be timely processed, the risk of fire is high, and the safety is low. By arranging two opposite optical fibers 1 in the sheath 2, for example one optical fiber 1 in a first region and the other optical fiber 1 in a second region opposite to the first region, both material costs and detection effects can be taken into account. When the second area breaks, although the luminous flux of the optical fiber 1 arranged in the first area may not change, the luminous flux of the optical fiber 1 arranged in the second area changes, and the detection piece can detect abnormality, so that the breakage of the cable sheath 2 can be timely handled, the risk of fire is reduced, and the safety is improved.

Optionally, the number of the optical fibers 1 is between three and six, and the optical fibers 1 are uniformly distributed in the sheath 2 at intervals.

It should be understood that, under the condition of not considering material cost, three to six optical fibers 1 can be arranged and distributed in the sheath 2 at even intervals, so that the sensitivity of the optical fibers 1 to the damage reaction of the sheath 2 in different areas can be enhanced on the premise that the signals of the optical fibers 1 do not interfere with each other, the risk of fire is further reduced, and the safety is improved.
