But a kind of ice-melt Optical Fiber composite overhead Ground Wire
Technical field
But the utility model relates to a kind of ice-melt Optical Fiber composite overhead Ground Wire, be mainly used in icing multiple district electrical network, be rapidly heated after the through-flow novel ground wire of ice-melt of can realizing of being specially adapted to that the ice damage prone areas uses.
Background technology
China is the serious country of coated by ice of overhead power transmission line disaster, enter the new century after the occurrence frequency of transmission line ice damage accident obviously increase, suffer a loss more serious.Between 2003 to 2010, the whole nation surpasses 1000 kilometers because line ice coating causes the fracture of line cord optical cable according to incompletely statistics, and shaft tower collapses and surpasses more than 120, drops into a large amount of human and material resources, financial resources when the disaster area rebuilds.
South electric network had suffered serious line ice coating disaster in 2008, caused large tracts of land electric power, communication disruption.Many the units such as south electric network, Guangdong designing institute line ice-melting technology that begins one's study after calamity.Therefore the function of wire is carried electric current exactly, and directly energising heats up and just can reach the ice-melt effect to wire, but ground wire deicing is more difficult, Optical Fiber composite overhead Ground Wire particularly, and because mounting means is by tower ground connection, can't the galvanization ice-melt.But domestic temporary without ripe ice-melt Optical Fiber composite overhead Ground Wire.
The utility model content
But the purpose of this utility model is to provide a kind of ice-melt Optical Fiber composite overhead Ground Wire for above-mentioned weak point, the properties that had both had the ordinary optic fibre composite overhead ground wire, can realize again the ice-melt that is rapidly heated after through-flow, reduce the disconnected long-time power outage that causes of cable shaft tower after the cable icing.
But a kind of ice-melt Optical Fiber composite overhead Ground Wire takes following technical scheme to realize:
But a kind of ice-melt Optical Fiber composite overhead Ground Wire comprises optical fiber, optical fiber ointment, stainless steel tube, insulated electric conductor monofilament, protection metal pipe and aluminium Baogang monofilament, and at least 12 optical fiber are housed in stainless steel tube, and is filled with optical fiber ointment and forms the stainless steel fiber unit; Be surrounded by insulating barrier in insulated electric conductor monofilament outside; Some eradication edge conductor monofilament and stainless steel fiber unit are stranded, form through-flow conductor; Through-flow conductor has the layer of metal protection tube of extruding continuously outward, protects through-flow conductor in construction and cracky not in using; The outer evenly stranded some aluminium Baogang monofilament of protection metal pipe.
Described aluminium Baogang monofilament is provided with 12 at least.
Evenly be surrounded with one deck lapping layer outside described through-flow conductor; Described lapping layer material comprises polyimide film, aramid yarn or organdy.The effect of lapping layer is the more compact structure that guarantees through-flow conductor.
The optical fiber of placing in described stainless steel tube is 12~48.
Described stainless steel fiber unit external diameter is φ 2.0~φ 3.6mm.
Described insulated electric conductor monofilament comprises insulation hard-drawn aluminium wire monofilament, insulation aluminium alloy monofilament, insulated copper wire monofilament or insulated copper alloy filaments, at least 7 of described insulated electric conductor monofilament settings.
Described insulated electric conductor monofilament external diameter is φ 2.0~φ 3.6mm.
The insulating layer material of described insulated electric conductor monofilament comprises polyester, polyester-imide, polyimides, polyimides-F46 composite membrane or fluoroplastic insulation material.
The thickness of insulating layer of described insulated electric conductor monofilament is 0.02~2.0mm.
Described protection metal pipe is one deck aluminium, aluminium alloy or copper, the copper alloy of extruding continuously outside through-flow conductor, protects through-flow conductor not to be subjected to damage.
The thickness of described protection metal pipe is 0.5~2.5mm.
But this ice-melt Optical Fiber composite overhead Ground Wire is reasonable in design, and practicality is good.The properties that had both had the ordinary optic fibre composite overhead ground wire, can realize again the ice-melt that is rapidly heated after through-flow, can take directly the through-flow method of this ground wire to be carried out ice-melt the disconnected long-time power outage that causes of cable shaft tower after minimizing Optical Fiber composite overhead Ground Wire icing after icing.
But the advantage of ice-melt Optical Fiber composite overhead Ground Wire is specific as follows:
1, good through-flow intensification performance.Through-flow conductor is arranged in this Optical Fiber composite overhead Ground Wire, ground wire is carried out through-flow intensification, can melt the surperficial icing of ground wire.
2, the insulation of through-flow conductor and outer layer metal protection tube and aluminium Baogang is separated by, and does not need when through-flow to keep the Optical Fiber composite overhead Ground Wire original function constant the ground wire insulation.
3, outer aluminium armored structure had both guaranteed the mechanical performance of Optical Fiber composite overhead Ground Wire, had guaranteed again lightning protection characteristic and the short-circuit protection performance of ground wire.
