Description
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 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.
