Description

New type corrosion resistant vibration-proof conductor
Technical field
The utility model belongs to overhead transmission line technical field, is specifically related to a kind of new type corrosion resistant vibration-proof conductor.
Background technology
Overhead transmission line generally uses steel reinforced aluminium conductor or steel core aluminum alloy stranded wire, and wherein: steel core (custom claims strengthening core, as follows) is galvanized strand wires or aluminum-cladding stranded wire, it is as reinforcement load part; And aluminium stranded conductor or aluminium alloy stranded conductor are as current-carrying part.With regard to the structure of this overhead transmission line, the steel core taken on by galvanized strand wires or aluminum-cladding stranded wire and aforesaid reinforcement load part are in innermost layer, the current-carrying part taken on by aluminium stranded conductor or aluminium alloy stranded conductor is in skin, and that is current-carrying part is closely stranded in and strengthens outside load part.
The overhead transmission line of said structure be in large span (bar and bar or the spacing between tower and tower) or meteorological condition is severe on the way time, circuit is because Long-Time Service is because being corroded and being destroyed by wind-induced vibration, there is the accident of broken string, disconnected bar, tower and so on, affect the continuity of transmission of electricity and even cause serious accident.
In order to improve corrosion resistance and the vibration resistance of overhead transmission line, traditional measure is: namely between steel core wire and aluminium stranded conductor, apply anticorrosion grease at steel core, is play refuse water effect by anticorrosion grease, stops rainwater, moisture and corrosive gas invasion and attack steel strand wire.But the weight of transmission line can be enlarged markedly owing to applying anticorrosion grease, make bar apart from, tower apart from change, increase the quantity of bar, tower, cause the wasting of resources on the one hand, increase electric power facility cost on the other hand, then improve on the one hand use in manage and protect cost.In addition, the poor durability of anticorrosion grease, As time goes on can be aging gradually until lost efficacy.Adopt aluminum-cladding stranded wire or adopt quality % and replace plating core steel strand wire than the aluminium being about 5%-alloy layer steel wire, make the steel core as reinforcing element be tending towards identical with the metal of the part that aluminium stranded conductor contacts and use to avoid the formation of primary cell, stop electrochemical corrosion, this measure has positive effect to raising corrosion resistance, but without helping in raising vibration resistance.
Wire hangs the vibration resistance that stockbridge damper can improve wire, but circuit deadweight can be increased and improve line cost and stockbridge damper is helpless to the anticorrosion of wire.Change conductor structure and such as the aluminium stranded conductor as current-carrying part is made self damping conductor, but the complicated cost of this conductor structure is high and do not have anticorrosion ability equally.
Chinese patent Authorization Notice No. CN2144340Y(patent No. ZL92221578.2) recommend have " corrosion-proof vibration-proof wire ", be in the steel strand wire of wire core and strandedly a free from flaw be set between the aluminum steel as current-carrying part of steel strand wire outside and the smooth aluminium lamination of inner surface, that is aluminium lamination is set outside steel strand wire, and between aluminium lamination and steel strand wire, maintains the distance being less than 10 ㎜.Although the wire of this structure can promote the corrosion resisting property of steel strand wire, but due to the tensile strength of whole wire be affected, wire weight increases and vibration resistance is limited, is not suitable for the erection of large span or the part of path that (along the line) meteorological condition is severe on the way.
Summary of the invention
Task of the present utility model is to provide a kind of both having contributed to that strengthening core is embodied excellent anticorrosion effect, desirable intensity and lightweight effect, is conducive to again making wire embody the new type corrosion resistant vibration-proof conductor of good vibrationproof performance.
Task of the present utility model has been come like this, a kind of new type corrosion resistant vibration-proof conductor, comprise strengthening core and be positioned at the stranded conductor outside strengthening core, described strengthening core is fiber glass core, carbon fiber complex core or basalt fibre core, and described stranded conductor is aluminium stranded conductor or aluminium alloy stranded conductor.
In a specific embodiment of the present utility model, described fiber glass core is simple solid fiber glass core; Described carbon fiber complex core is simple solid carbon fiber complex core; Described basalt fibre core is simple solid basalt fibre core.
In another specific embodiment of the present utility model, described fiber glass core is the mutually stranded stranded glass fibers cores of 2 to 6 strands of glass fiber bundles; Described carbon fiber complex core is the mutually stranded stranded carbon fiber cores of 2 to 6 strands of carbon fiber bundles; Described basalt fibre core is the mutually stranded stranded basalt fibre cores of 2 to 6 strands of basalt fibre bundles.
In another specific embodiment of the present utility model, the shape of cross section of described stranded conductor is circular, fan-shaped, trapezoidal, semicircle or herringbone.
In another specific embodiment of the present utility model, be outside equipped with overcoat at described strengthening core, this overcoat is metal tube or insulation filler, and maintains gap between metal tube and described strengthening core.
Also have in a specific embodiment of the present utility model, described metal tube wall thickness is 0.05-1.2mm.
More of the present utility model and in a specific embodiment, described metal tube is aluminum pipe or copper pipe.
In an of the present utility model and then specific embodiment, described filler is epoxy resin; Described gap is 1-3mm.
Of the present utility model again more and in a specific embodiment, the number of plies of described stranded conductor is one deck or more.
In an again of the present utility model and then specific embodiment, outside described stranded conductor, be combined with layer of polyurethane.
The technical scheme that the utility model provides is owing to have employed fiber glass core, carbon fiber complex core or basalt fibre core as strengthening core, and outside strengthening core, be provided with overcoat, thus there is corrosion resistance, vibration resistance and intensity and weight significantly alleviates, the erection requirement of large span and weather conditions are severe part of path can be met on the way.
