Abstract
The invention discloses a thunderstrike-resistant low-sag optical fiber composite overhead ground wire which comprises a carbon fiber composite reinforcing core. A plurality of metal wires and an optical unit are intertwisted outside the carbon fiber composite reinforcing core. A plurality of metal wires are intertwisted outside the metal wires and the optical unit. Each metal wire comprises a steel wire and a zinc layer outside the steel wire. The optical unit comprises a plurality of optical fibers, and a stainless steel sleeve is arranged outside the optical fibers. The center line of the thunderstrike-resistant low-sag optical fiber composite overhead ground wire is the carbon fiber composite reinforcing core which has the advantages of being low in specific gravity, high in strength and resistant to high temperature; the expansion coefficient of the ground wire is small at a high temperature, the sag is not prone to enlargement, and therefore the safety and reliability of the operation of the ground wire are improved; the structure that the metal wires in the inner layer and the outer layer are intertwisted forms the zinc layers plated outside the steel wires, the specific heat and melting point of zinc are low, heat generated when the ground wire encounters thunderstrike can diffuse easily, therefore, the zinc-coated wires cannot be struck off easily, and the ground wire is not prone to damage.
Description
Technical field
The present invention relates to a kind of overhead ground wire of transmission line, especially the anti-thunderbolt Optical Fiber composite overhead Ground Wire of low arc drop.
Background technology
The Optical Fiber composite overhead Ground Wire of existing transmission line is twisted metal wires and making outside the fiber unit of making sleeve pipe with stainless steel tube generally, metal wire is generally aluminium-clad steel wire or aluminium alloy wire, this Optical Fiber composite overhead Ground Wire sag is large, while meeting thunderbolt, the aluminum metal lines of its outsourcing is easily struck off, and causes ground wire to damage.
?
Summary of the invention
The invention provides a kind of low arc drop of anti-thunderbolt Optical Fiber composite overhead Ground Wire, have that sag is low, intensity is large, the advantage such as high temperature resistant, anti-thunderbolt, but the useful life of extended fiber composite overhead ground wire.
For addressing the above problem, the present invention adopts following technical scheme: a kind of low arc drop of anti-thunderbolt Optical Fiber composite overhead Ground Wire, comprise the carbon fiber compound reinforced core, its carbon fiber compound reinforced core outer stranded have some wires and a light unit, stranded outside metal wire and light unit have some wires; Described metal wire comprises steel wire and the outer zinc layer of steel wire; Described smooth unit comprises some optical fiber, and optical fiber is outside equipped with the stainless steel sleeve pipe.
Center line of the present invention is the carbon fiber compound reinforced core, and the carbon fiber compound reinforced core has the advantages such as proportion is little, intensity is large, high temperature resistant, and at high temperature coefficient of linear expansion is little, and sag is difficult for increasing, therefore improved the safety and reliability of ground wire operation; The structure of the metal wire that ectonexine is stranded is the outer plating zinc layer of steel wire, and the specific heat of zinc and fusing point are lower, and the heat produced when ground wire is subject to being struck by lightning easily distributes, therefore zinc-coated wire is difficult for being struck off, ground wire is just not fragile.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
below with best embodiment, the present invention is described in detail
.
As shown in Figure 1, the present invention is a kind of low arc drop of anti-thunderbolt Optical Fiber composite overhead Ground Wire, comprise carbon fiber compound reinforced core 2, its carbon fiber compound reinforced core 2 outer stranded have some wires 1 and a light unit 5, the outer stranded some wires 1 that have in metal wire 1 and light unit 5; Described metal wire 1 comprises steel wire 6 and the outer zinc layer 7 of steel wire 6, and light unit 5 comprises some optical fiber 4, and optical fiber 4 is outside equipped with stainless steel sleeve pipe 3.Center line of the present invention is the carbon fiber compound reinforced core, and the carbon fiber compound reinforced core has the advantages such as proportion is little, intensity is large, high temperature resistant, and at high temperature coefficient of linear expansion is little, and sag is difficult for increasing, therefore improved the safety and reliability of ground wire operation; The structure of the metal wire that ectonexine is stranded is the outer plating zinc layer of steel wire, and the specific heat of zinc and fusing point are lower, and the heat produced when ground wire is subject to being struck by lightning easily distributes, therefore zinc-coated wire is difficult for being struck off, ground wire is just not fragile.
Finally it should be noted that: obviously, above-described embodiment is only for example of the present invention clearly is described, and is not the restriction to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And the apparent variation of being amplified out thus or change are still among protection scope of the present invention.
