Abstract
The invention relates to an external application type melting ice optical fiber composite overhead ground wire which is mainly applied to power grids in icing prone areas. The external application type melting ice optical fiber composite overhead ground wire is designed for ice damage prone regions, when the composite overhead ground wire is wrapped by ice, insulated wires are powered on to be heated to achieve ice melting, and long-time power failure accidents caused by the fact that a wire tower is broken and collapsed after the wires are wrapped with the ice are avoided. The external application type melting ice optical fiber composite overhead ground wire comprises an optical fiber composite overhead ground wire body, the insulated wires and a clamp hoop; the one or more insulated wires are directly paved on the surface of the optical fiber composite overhead ground wire body and fixed through the clamp hoop, and then the external application type melting ice optical fiber composite overhead ground wire is formed. Each insulated wire is composed of a steel wire stranded wire, enameling metal wires, an insulated layer and a protection layer, the multiple enameling metal wires are evenly stranded outside the steel wire stranded wire for form conductors of the insulated wires, the insulated layer is arranged outside the conductors in a lapping or longitudinal wrapping mode, the protection layer is arranged outside the insulated layer in an extrusion molding or wrapping mode, and the insulation stability of the insulated layer is protected.
Description
Technical field
What the present invention relates to is that a kind of external application formula can ice-melt Optical Fiber composite overhead Ground Wire, is mainly used in the multiple district of icing electrical network; A kind of external application formula that the present invention be directed to ice damage prone areas design can ice-melt Optical Fiber composite overhead Ground Wire, in the time of Optical Fiber composite overhead Ground Wire icing, insulated conductor is carried out to galvanization intensification ice-melt, stop the disconnected long-time power outage causing of cable shaft tower after cable icing.
Background technology
China is the country that coated by ice of overhead power transmission line disaster is serious, enter the new century after the occurrence frequency of transmission line ice damage accident obviously increase, suffer a loss more serious.Within 2008, south electric network has suffered serious line ice coating disaster, causes large area electric power, communication disruption.The function of wire is carried electric current exactly, therefore directly just can reach ice-melt effect to wire energising intensification, but ground wire deicing is more difficult, particularly Optical Fiber composite overhead Ground Wire, and because mounting means is by tower ground connection, cannot galvanization ice-melt.Domestic temporary without ripe external application ice-melt Optical Fiber composite overhead Ground Wire and ice-melting mode thereof.
Summary of the invention
A kind of external application formula of providing for above-mentioned weak point is provided can ice-melt Optical Fiber composite overhead Ground Wire, after ground wire icing, take directly the alive method of insulated conductor to be removed to ground wire surface icing, stop the disconnected cable accident of Optical Fiber composite overhead Ground Wire icing.
External application formula can ice-melt Optical Fiber composite overhead Ground Wire be achieved through the following technical solutions:
External application formula can ice-melt Optical Fiber composite overhead Ground Wire comprise Optical Fiber composite overhead Ground Wire, insulated conductor and clip.Directly lay one or more insulated conductor on Optical Fiber composite overhead Ground Wire surface, adopt clip to fix, forming external application formula can ice-melt Optical Fiber composite overhead Ground Wire.Insulated conductor is made up of steel strand wire, conductor, insulating barrier, protective layer; even stranded some enamel-cover metal wires outside steel wire twisted wire; the conductor of composition insulated conductor; outer wrapped or vertical bag one layer insulating of conductor; at insulating barrier extrusion molding or coated layer protective layer more outward, protection insulating barrier insulation stability.
Insulated conductor is directly fixed on any one side of Optical Fiber composite overhead Ground Wire with clip, or is wrapped in outside Optical Fiber composite overhead Ground Wire.
Described Optical Fiber composite overhead Ground Wire refers to have the metal optical cable of electric power overhead ground wire and optical fiber communication ability dual-use function.Optical Fiber composite overhead Ground Wire (Optical fiber composite overheadgroundwiers, be called for short OPGW) be the ground wire for the new structure of high voltage power transmisson system communication line, there is the dual-use function of common overhead ground wire and communications optical cable.
The insulating barrier of described insulated conductor adopts polyimide film or the vertical bag of polyester film or wrapped at conductor skin, excellent insulation performance,
The protective layer of described insulated conductor is extrusion molding or be coated on the outer field sheath of insulating barrier, can be metal carbonyl coat, or polymer covering layer, and Main Function is that protection insulating barrier is injury-free in the time of construction, ensures the insulation property of insulated conductor long-term stability
Described clip, for insulated conductor is close to the surface that is fixed on Optical Fiber composite overhead Ground Wire, is best for the long-term dependability of clip adopts stainless steel and aluminum alloy materials.
This external application formula ice-melt optical power grounded waveguide is reasonable in design, and practicality is good.The external application formula ice-melt Optical Fiber composite overhead Ground Wire of making through the present invention has following technical characterstic:
1, insulated conductor diameter is little, and electric property excellence, quality are light.Easy construction.
2, ice-melt performance.After Optical Fiber composite overhead Ground Wire icing, can directly give the conductor dbus electric current of insulated conductor, insulated conductor and Optical Fiber composite overhead Ground Wire bulk temperature are raise, ice-melt surface icing.
3, stable insulation is reliable.Lead conductor has multi-insulation protection outward, internal layer polyimide film, and the outer protection that also has insulating barrier, insulation property long-term safety is reliable and stable.
