DL/T832-2003 (enforcement on June 1st, 2003), OPGW are erected at overhead power transmission line pole tower
Top, mainly carries and prevents thunder and lightning from attacking aerial phase line and the dual-use function of the communication system of power grids on power transmission line directly.
Meanwhile, current OPGW structure uses rustless steel light unit substantially, uses concentric stranding.Big according to sectional area
I is typically designed as one layer or two-layer.In small cross-sectional area double-decker, want to meet entire outer diameter
Ask, outer layer filament diameter have to be reduced, although the technical parameter such as pull-off force, short-circuit current capability is still
Meet design requirement, but anti-lightning performance can not be guaranteed.Outer layer filament diameter is too small, and OPGW suffers thunder
When hitting, it may occur that plied monofilament is struck by lightning disconnected, the fiber unit undertaking communication function also subjects to the thing of damage
Therefore.
Summary of the invention
For the problems referred to above, this utility model provides a kind of aluminium pipe structure of resistance to thunderbolt optical fiber composite overhead ground
Line, original small cross-sectional area double-decker is designed as one layer by it, improves outer layer aluminum Baogang filament diameter, enters
And improve withstand-lightning capability, make monofilament lightning-caused breaking accident significantly reduce, extend the use of optical cable
Life-span, reduce unnecessary economic loss.
A kind of aluminium pipe structure of resistance to thunderbolt OPGW, it is characterised in that: it include core arrangement,
Outer contact, is provided with described core arrangement in the cavity that described outer contact is formed, described inner core is tied
Structure includes light unit, aluminum pipe, and described smooth unit is specially rustless steel light unit, described rustless steel light list
The inside of unit is disposed with optical fiber, and described rustless steel light unit is positioned at the central circular cavity body of described aluminum pipe,
Described outer contact passes through the stranded molding of monofilament of aluminum Baogang, and the aluminum Baogang monofilament of outer contact is stranded in described
The outer wall of aluminum pipe.
It is further characterized by
The aluminum Baogang monofilament of described outer contact is specially high intensity aluminum Baogang monofilament；
The quantity of the aluminum Baogang monofilament of described outer layer monomer is 8～13, and it makes whole outer layer aluminum Baogang
The diameter of monofilament becomes big；
Described rustless steel light unit remaining a length of 4 ‰-5 ‰, it is ensured that the performance of total.
After using technique scheme, it uses aluminum bag stainless steel tube structure light unit, at original rustless steel
Light unit is outer according to light unit external diameter in the minds of design uniform cladding aluminium lamination raising, and it is by original small cross-sectional area
Double-decker is designed as one layer, improves outer layer aluminum Baogang filament diameter, and then improves withstand-lightning capability,
Make monofilament lightning-caused breaking accident significantly reduce, extend the service life of optical cable, reduce unnecessary warp
Ji loss.
Accompanying drawing explanation
Fig. 1 is the cross-sectional cut-away structural representation of specific embodiment of the utility model；
In figure, the title corresponding to sequence number is as follows:
Core arrangement 1, outer contact 2, aluminum pipe 3, rustless steel light unit 4, optical fiber 5, aluminum Baogang monofilament
6。
Detailed description of the invention
A kind of aluminium pipe structure of resistance to thunderbolt OPGW, is shown in Fig. 1: it includes core arrangement 1, outer
Layer conductor 2, is provided with core arrangement 1 in the cavity that outer contact 2 is formed, core arrangement includes light
Unit, aluminum pipe 3, light unit is specially rustless steel light unit 4, and the inside of rustless steel light unit 4 is disposed with
Optical fiber 5, rustless steel light unit 4 is positioned at the central circular cavity body of aluminum pipe 3, and outer contact 2 is by aluminum bag
The stranded molding of steel monofilament 6, the aluminum Baogang monofilament 6 of outer contact 2 is stranded in the outer wall of aluminum pipe 3.
The aluminum Baogang monofilament 6 of outer contact 2 specially high intensity aluminum Baogang monofilament；
The quantity of the aluminum Baogang monofilament 6 of outer contact 2 is 8～13, and it makes whole outer layer aluminum Baogang
The diameter of monofilament 6 becomes big；
Rustless steel light unit 4 remaining a length of 4 ‰-5 ‰, it is ensured that the performance of total.
Specific embodiment, is shown in that the outer ring surface of Fig. 1: aluminum pipe 3 is stranded and is disposed with eight Gen Lv Baogang monofilament 6, aluminum
It is provided with rustless steel light unit 4 in the central circular cavity body of pipe 3, in rustless steel light unit 4, is disposed with optical fiber
5, the quantity of optical fiber is arranged according to practical situation.
It has the beneficial effect that: (1), in sectional area is identical, and aluminium pipe structure strand material external diameter is the biggest
In conventional double integrated structure.There is the withstand-lightning capability of highly significant；(2), strand material uses high intensity
Aluminum Baogang monofilament, optical cable entirety pull-off force does not receive the aluminum pipe low impact of sectional area intensity, the most
Promote.Can substantially reduce optical cable installation sag；(3) aluminum pipe electric conductivity is excellent, participates in short in calculating
Road current capacity calculates, and can quickly be shifted by electric charge when short circuit or thunderbolt, reduces optical cable local and burns
Wound；(4) sectional area between former single layer structure and double-decker has been filled up blank；(5) aluminum pipe and outer layer
Aluminum Baogang is commaterial, reduces the electrochemical corrosion in the past between rustless steel and aluminum Baogang, has
Excellent decay resistance.
Above specific embodiment of the utility model is described in detail, but content has been only this practicality newly
The preferred embodiment that type is created, it is impossible to be considered for limiting the practical range that this utility model is created.All
Create, according to this utility model, impartial change and the improvement etc. that application range is made, all should still belong to this practicality
Within novel patent covering scope.
