The outer wraparound ice-melting optical fiber composite overhead ground wire is designed for the areas with frequent ice damages, when the ground wire is coated by ice, the insulate sheet wire is subjected to current-carrying warming for melting the ice, so that long-time power failure caused by the breaking and falling of a cable tower after the cable is coated by the ice is stopped. The outer wraparound ice-melting optical fiber composite overhead ground wire comprises optical fiber composite overhead ground wires, an insulating sheet wire, and a clamp, wherein the insulating sheet wire is laid directly on the surface of the optical fiber composite overhead ground wires; the insulating sheet wire is fixed on the surface of the optical fiber composite overhead ground wires by adopting the clamp; at least one insulating sheet wire is arranged; the insulating sheet wire is composed of a sheet wire conductor, polyimide films, and an insulating layer; the polyimide films of 2-4 layers and with the thickness of 0.38-0.5 mm are wrapped uniformly outside the sheet wire conductor; and the insulating layer with the thickness of 0.2-0.8 mm is extruded outside the polyimide films.

Description

A kind of outer formula ice-melt Optical Fiber composite overhead Ground Wire that twines

Technical field

The utility model relates to and a kind ofly outer twine formula ice-melt Optical Fiber composite overhead Ground Wire, be mainly used in the multiple district of icing electrical network.The utility model is to twine formula ice-melt Optical Fiber composite overhead Ground Wire for a kind of outer of ice damage prone areas design, when ground wire icing, insulation lenticular wire is carried out to galvanization intensification ice-melt, stops 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.Therefore the function of wire is carried electric current exactly, and directly to wire, energising heats up and just can reach ice-melt effect, but ground wire deicing is more difficult, Optical Fiber composite overhead Ground Wire particularly, and because mounting means is by tower ground connection, cannot galvanization ice-melt.Domestic temporary without ripe outer ice-melt Optical Fiber composite overhead Ground Wire and the ice-melting mode thereof of twining.

Summary of the invention

The utility model object is a kind of outer formula ice-melt Optical Fiber composite overhead Ground Wire that twines providing for above-mentioned weak point, after ground wire icing, take directly the alive method of this insulation lenticular wire to be removed to ground wire surface icing, stop the disconnected cable accident of Optical Fiber composite overhead Ground Wire icing.

Outside a kind of, twining formula ice-melt Optical Fiber composite overhead Ground Wire is achieved through the following technical solutions:

A kind of outer formula ice-melt Optical Fiber composite overhead Ground Wire that twines comprises Optical Fiber composite overhead Ground Wire, insulation lenticular wire and clip.On Optical Fiber composite overhead Ground Wire surface, directly lay insulation lenticular wire, insulation lenticular wire adopts clip to be fixed on Optical Fiber composite overhead Ground Wire surface.

Described insulation lenticular wire is at least provided with 1.

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 overhead groundwiers is called for short OPGW) is the ground wire for the new structure of high voltage power transmisson system communication line, has the dual-use function of common overhead ground wire and communications optical cable.

Described insulation lenticular wire is comprised of lenticular wire conductor, polyimide film and insulating barrier.The polyimide film that evenly wrapped 2～4 layer thicknesses are 0.38～0.5mm outside lenticular wire conductor, then squeezes at polyimide film the insulating barrier that a layer thickness is about 0.2～0.8mm outward.Described lenticular wire conductor comprises flat hard-drawn aluminium wire, flat aluminium alloy wire, flat cable copper conductor, flat copper alloy wire.Described insulating barrier insulating material is crosslinked polyethylene.Insulating barrier, except insulation, also plays the function of protection internal layer polyimide film, and described polyimide film is high-temperature insulation material, has guaranteed like this insulation property steady in a long-term of insulation lenticular wire.

Described insulation lenticular wire cross section is rectangle, can more fit tightly Optical Fiber composite overhead Ground Wire.The long limit laminating Optical Fiber composite overhead Ground Wire of lenticular wire.According to the lenticular wire of the structure choice different size of the situation of each department icing and Optical Fiber composite overhead Ground Wire.Convenient for cable laying operation, fail to grow up in 8mm in described insulation lenticular wire cross section, the wide 6mm that is not more than.

Described clip is for insulation lenticular wire is close to the surface that is fixed on Optical Fiber composite overhead Ground Wire, and for the long-term dependability of clip, described clip 3 adopts stainless steel and aluminum alloy materials.

Outside a kind of, twine formula ice-melt optical power grounded waveguide reasonable in design, practicality is good.The outer formula ice-melt Optical Fiber composite overhead Ground Wire that twines of making through the utility model has following technical characterstic:

1, lay conveniently.This structure can directly be produced for new line and directly set up, also can be for the transformation of old circuit.On the circuit of existing Optical Fiber composite overhead Ground Wire, directly lay insulation lenticular wire then fixing with clip, construct very convenient.

2, ice-melt performance.After Optical Fiber composite overhead Ground Wire icing, can directly give insulation lenticular wire galvanization, be that insulation lenticular wire and Optical Fiber composite overhead Ground Wire bulk temperature raise, ice-melt surface icing.
