Abstract
The utility model belongs to an overhead wire taking a fibrous core as load bearing and in particular relates to a fibrous insulation core overhead wire. Outer-layer glass fiber is extremely easy to mix into the carbon fiber wire of the current common carbon fiber composite core wire, the current common carbon fiber composite core wire is contacted with a conductor, so that the carbon fiber core is not completely insulated with the conductor, and a detection method utilizing the conductive characteristics of the carbon fiber can not be implemented. The utility model aims at providing the fibrous insulation core overhead wire. The fibrous insulation core overhead wire is characterized by consisting of two parts, namely a wire core and the conductor, wherein the wire core part is composed of a bearing tensile part and an insulation part as well as a protection part, and the conductor layer is twisted outside the wire core. According to the utility model, the bearing tensile part of the wire core is insulated with the conductor, and the wire core of a wire is detected by utilizing the conductive characteristics of the carbon fiber, thereby solving the defects of the existing fiber composite core wire.
Description
Technical field
The utility model belongs to a kind of and does the aerial condutor of carrying, definite a kind of fiber insulation core aerial condutor of saying so by fibre core.
Background technology
Present common fiber composite core lead; Strengthen cable and manufacturing approach, Chinese patent 200520072074.2 carbon fiber complex core aluminium stranded conductors and insulated cable, United States Patent (USP) 20040131834 etc. like one Chinese patent application 038092840 aluminum conductor composite core; Its processing mode is that carbon fiber wire and glass fiber are immersed epoxy resin; Through the hot curing moulding, become carbon fiber complex core, become carbon fiber composite core wire at composite core exterior layer strand conductor.But its bending and crash worthiness can be poor, and small damage has the trend that enlarges destruction along tow direction cracking, especially to the power circuit in operation, are prone to take place the broken string major accident.Need be before carbon fiber complex core layer strand outer conductor, and before the wire erection it is detected and detect a flaw, as utilize the electric conduction of carbon fiber characteristic to detect.Again because when carbon fiber wire and glass fiber dipping; Carbon fiber wire is very easily sneaked into the glass outer fiber; And contact with conductor, make to make not exclusively insulation between carbon fiber core and the conductor and utilize the electric conduction of carbon fiber characteristic can not carry out to the detection method of lead core.
Summary of the invention
The purpose of the utility model is to provide a kind of fiber insulation core aerial condutor.It is characterized in that being made up of core and conductor two parts, core part constitutes by carrying tension part and insulated part, guard section, and the conductor layer strand is outside at core.Make and can utilize the carrying tension part and the conductor insulation of core the electric conduction of carbon fiber characteristic that the lead core is detected, thereby solve existing fiber composite core lead defective.
In order to solve the problem that prior art exists, the technical scheme that the utility model adopts is:
High strength fibre is through twisting or braiding; Form bar-shaped twisting fibre bundle core or the braided fiber core of bar; Carrying tension part as lead; The outside of carrying the tension part has insulation resistance to be not less than the insulated part of 0.5M Ω, and there is the guard section of twisting fiber or braided fiber formation in the outside of insulated part, and there is the conductor of layer strand in the outside of guard section.The carrying tension partly is used for strengthening the tensile strength of lead; Insulated part is used for intercepting carrying tension part and conductor current conducting; Guard section improves the side direction bending and the crash worthiness ability of lead, and conductor is used for conducting electric current, electric energy transmitting.
The beneficial effect of the utility model is that the side direction that has strengthened the raising lead bends and the crash worthiness ability, and conductor and core are insulated fully, helps detecting.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing is the vertical section sketch map of the utility model embodiment.
In the accompanying drawing, 1. carry tension part 2. insulated parts 3. guard sections 4. conductors.
Embodiment
High strength fibre is through twisting or braiding; Form bar-shaped twisting fibre bundle core or the braided fiber Shu Xin of bar; Carrying tension part 1 as lead; The outside of carrying tension part 1 has insulation resistance to be not less than the insulated part 2 of 0.5M Ω, and there is the guard section 3 of twisting fiber or braided fiber formation in the outside of insulated part, and there is the conductor 4 of layer strand in the outside of guard section 3.
The fibre bundle core that carries tension part 1 also can be the impregnating resin structure, to improve physicochemical property.
Claims (2)
1. fiber insulation core aerial condutor; It is characterized in that high strength fibre is through twisting or braiding; Form bar-shaped twisting fibre bundle core or the braided fiber Shu Xin of bar, as the carrying tension part of lead, there is insulated part in the outside of carrying the tension part; The guard section that the outside of insulated part has twisting fiber or braided fiber to constitute, there is the conductor of layer strand in the outside of guard section.
2. according to claim 1, a kind of fiber insulation core aerial condutor is characterized in that the fibre bundle core is the impregnating resin structure.
