Description
Technical field
The present invention relates to one and be applicable to 500kV and above strain tower of transmission line drainage thread anti-wear sheath.
Background technology
Drainage thread is the lead-in wire connecting load shaft tower (strain insulator, corner and terminal shaft tower) both sides wire, also referred to as wire jumper.
At present, transmission line of electricity is primarily present problems with for the sleeve pipe of anchor support drainage thread abrasionproof: (1) sheath is mainly used
Iron wire is tied up, and easily corrosion, shifts, comes off, and drainage thread friction grading ring causes wire impaired.(2) sheath is daily flexible pipe,
Aging speed is fast, easily wear out failure.
Summary of the invention
It is an object of the invention to provide the simple in construction on a kind of 500kV of being applicable to and above transmission line of electricity, be difficult to displacement
Come off and durable anchor support drainage thread anti-wear sheath.
The present invention is achieved by the following technical solutions:
One is applicable to 500kV and above strain tower of transmission line drainage thread anti-wear sheath, and it includes sleeve and fixing seat, described
The side that sleeve is thick is contact side, and thin side is fixing side, and described fixing side is provided with axial arranged fracture, described fixing
On the outer tube wall of the fracture both sides that seat is symmetricly set on sleeve.
Furtherly, the wall thickness of described contact side is more than the wall thickness of fixing side.
Furtherly, the inner tube wall of described sleeve is arranged in the shape of a spiral.
Furtherly, the lateral surface of described fixing seat is provided with groove, is provided with circular hole in described groove.
Furtherly, it is connected with by circular hole between described fixing seat.
Furtherly, described sleeve and fixing seat are made up of corrosion-resistant, aging-resistant rubber or epoxide resin material.
After using technique scheme, the method have the advantages that
(1) this protector configurations is simple, easy to carry, ensures the safety of personnel during charged installation.
(2) this sheath contact surface is thicker, wear-resistant.
(3) this sheath inner tube wall is arranged in the shape of a spiral, matches with cable shape, can prevent from rotating, be not susceptible to displacement.
(4) this sheath bolt fastens, it is to avoid produce loosening, obscission after long-play.
(5) this sheath has anticorrosive property, and ageing resistace is good.
Present configuration is simple, and materials are few, low cost of manufacture, economical and practical, and this achievement in research improves what circuit ran
Safety coefficient, saves working time and intensity.
Accompanying drawing explanation
Fig. 1 is the structure chart of the present invention.
Fig. 2 is the front view of the present invention.
Fig. 3 is the profile of the present invention.
Fig. 4 is the use state diagram of the present invention.
Wherein, 1 sleeve, 2 fix seat, 3 bolts, 4 wires, 11 contact sides, 12 fix side, 13 fractures, 14 inner tube walls, 21 recessed
Groove, 22 circular holes.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is done the most concrete description.
As Figure 1-4, one is applicable to 500kV and above strain tower of transmission line drainage thread anti-wear sheath, and it includes
Sleeve 1 and fixing seat 2, described sleeve 1 includes that contact side 11 and fixing side 12, described fixing side 12 are provided with axial arranged breaking
Mouth 13, described fracture 13 length is identical with sleeve 1 length, the outer tube wall of described fracture 13 both sides is symmetrically arranged with and is perpendicular to cylinder
The fixing seat 2 of wall.The wall thickness of described contact side 11, more than the wall thickness of fixing side 12, is conducive to abrasion for a long time.
The inner tube wall 14 of described sleeve 1 is arranged in the shape of a spiral, forms owing to cable is usually many single line coilings in the shape of a spiral, can make set
Cylinder 1 and cable outline are the most identical, can prevent sheath from rotating, be not susceptible to displacement.The lateral surface of described fixing seat 2 is provided with
Groove 21, is provided with circular hole 22 in described groove 21, use bolt by circular hole 22 between two mutually symmetrical with described fixing seats 2
3 connect, and fasten with bolt 3, it is to avoid produce loosening, obscission after sheath long-play.
The profile of sleeve 1 can be cylindrical or prismatic, and fixing seat 2 can be circular or square, and groove 21 is permissible
Being circular trough or square groove, the number of fixing seat 2 is 4 or more than four.
As shown in Figure 4, sleeve 1 is sleeved on wire 4, and fixes seat 2 with bolt 3 by 3 groups and connect together, and can prevent three
Wire 4 contacts with each other.
The above embodiment is only the preferred embodiments of the present invention, and and the feasible enforcement of non-invention exhaustive.Right
For persons skilled in the art, on the premise of without departing substantially from the principle of the invention and spirit, done any aobvious to it
And the change being clear to, within all should being contemplated as falling with the claims of the present invention.
