Abstract

The utility model is an interlocking heterotype composite fiber optic overhead earth wire applied to the combination of an overhead transmission line and optical communication which takes a light unit composed of a metal or non-metal tube which contains optical fiber bundles or metal bunched wire which contains the light unit as an inner core. The outer layer of the utility model is twisted with a heterogeneous wire with tenons as an outer conductor layer and the heterogeneous wire with tenons is a heterogeneous aluminum clad steel wire or copper clad steel wire with a steel core the cross section of which is round or non-round. The inner and outer round of the cross section shape are concentric arcs, and the neighboring sides in the radial direction are distortion fan-shaped which are with concave-convex complementary including small arcs, broken lines or other arbitrary shapes with tenon structures. The cross section shape of the interlocking heterogeneous wire is a complete round ring shape after engaging into an integrated body. The utility model has the advantage that the effective carrying current cross-sectional area increases under the condition that the diameter of the composite fiber optic overhead earth wire does not change which enhances the mechanical strength and the carrying short-circuit current capacity. The utility model also has the advantages of lightning strike resistance, and uneasy dispersing which can ensure the safe, reliable, and normal operation of the overhead transmission line.

Description

The fine composite overhead ground wire of the special-shaped linear light of interlocking

Affiliated technical field

It is the Optical Fiber composite overhead Ground Wire that the overhead transmission line of OPGW combines with optical communication that the utility model relates to a kind of code name that is called for short, particularly twisted wire is the special-shaped line of non-circle, is with tenon structure and the mutual tightly Optical Fiber composite overhead Ground Wire of the worry of lock, no broken lot, i.e. the special-shaped linear light fibre of interlocking composite overhead ground wire.

Background technology

Existing Optical Fiber composite overhead Ground Wire forms with many circular wire rod concentric strandings, gap between line and line and layer and the layer is bigger, the short-circuit current of net sectional area and carrying is less, Optical Fiber composite overhead Ground Wire is erected at electric power transmission shaft tower top, subject to thunderbolt, in case be struck by lightning, even lightning strike spot is very little, also can be with a certain of its outer twisted wire or a few single line fusing, broken lot and constantly sagging can take place in the single line end that fuses under the effect of power such as wind-force and vibration, cause with phase line hypotelorism even collision and cause the transmission system short circuit, cause then that gently tripping operation has a power failure, when serious major accident will take place, power transmission system is badly damaged can not normally be moved.

Summary of the invention

In order under the constant prerequisite of external diameter, to improve the short-circuit current capability of net sectional area and carrying, improve the anti-thunderbolt performance of Optical Fiber composite overhead Ground Wire simultaneously, and overcome the existing fiber composite overhead ground wire significant drawback that broken lot can not normally move transmission system of being struck by lightning, the utility model provides the special-shaped line composite fiber of a kind of interlocking aerial earth wire, its outer field special-shaped molded lines has bigger thermal capacity can tolerate thunderbolt, because of these special-shaped lines have the unlikely broken lot of interlocking structure, guarantee that transmission line of electricity normally moves.

The technical scheme that its technical matters that solves the utility model adopts is: the special-shaped line structure optical fiber of a kind of interlocking composite overhead ground wire.It is characterized in that the light unit that constitutes with the metal that includes fibre bundle or nonmetallic pipe or be inner core outerly strandedly tenon profiled metal line is arranged as outer conductor layer at it with the metal twisted wire that contains the light unit; Above-mentioned described special-shaped aluminium Baogang or the copper covered steel molded lines that has the special-shaped line of tenon that circular or non-circular steel core are arranged in being, its shape of cross section is a concentric arcs for the fan-shaped promptly interior periphery of distortion, the radially adjoining limit be concavo-convex complementation contain little arc or broken line shape or other as band tenon structures such as S type, C type, L type, Z type have tenon distortion fan-shaped, the annular that its shape of cross section of the whole engagement of this interlocking abnormity molded lines back becomes one; The position of above-mentioned described smooth unit in the metal twisted wire can be in the center, also can be at eccentric position, and this metallic cable is an aluminum-clad steel wire, aluminium alloy wire, galvanized steel wire, copper-clad aluminum conductor or other suitable metal wire; The special-shaped line strand of above-mentioned described interlocking number layer by layer is individual layer or multilayer, and the shape of cross section of the internal layer twisted wire of special-shaped line strand layer is that circular, fan-shaped or concavo-convex complementation has tenon interlocking distortion fan-shaped.

The beneficial effects of the utility model are that the special-shaped line stranded layer of interlocking becomes the special ability thunderbolt of the one-piece construction that the tenon engagement is arranged mutually, are difficult for broken lot; Keeping having improved effective-current sectional area, physical strength and the carrying short-circuit current capability of Optical Fiber composite overhead Ground Wire under the constant prerequisite of external diameter, guaranteed the safe and reliable normal operation of overhead transmission line.
