Description
The utility model relates to the protection gold utensil of the installation gold utensil, particularly aerial condutor of ultra-high-tension power transmission line.
On ultra-high-tension power transmission line, the position of suspension clamp is installed on the lead, all looping has preformed armor rods to protect lines, is worn and torn by wire clamp to prevent lead.But, owing to the radius of curvature of protecting the lines both ends is big inadequately, being easy to produce corona discharge, this phenomenon is particularly serious on the 500KV transmission line in high area above sea level.The existing way that prevents to produce corona discharge is to have the position of suspension clamp to install on lead all to press shading ring and supporting gold utensils such as yoke plate thereof, because of its weight and volume is big, relatively difficulty is installed; Member is many, and manufacturing and installation cost are higher.
Given this, the purpose of this utility model is to provide a kind of ultra-high-tension power transmission line preformed armor rods that can prevent to protect lines end corona discharge, simple in structure, simple installation, transmission line anti-dizziness ball that cost is low.
Transmission line anti-dizziness ball of the present utility model (referring to accompanying drawing) comprises body (1) and pressing plate (2) with the spheroid that hinge arrangement constitutes, and the metallic channel that runs through spheroid and interior clamp pad thereof are arranged.
Above-mentioned spheroid can be flush end long ball shape, said body and platen shape can be symmetrical, said metallic channel can be the cavity shape of column, have along the macropore (3) and the aperture (4) of spheroid long axis polyphone, said clamp pad and aperture match, being involutory arranged and be symmetrical two watts of shape rubber blankets (10,11), watt shape rubber is lined with the boss (13) that matches with the counterbore (12) of aperture.
Above-mentioned hinge connects structure, can there be the metallic channel both sides that are placed in to be two symmetrical covers, the hinge arrangement of one side has at two pans on the body (or pressing plate) and a pan on pressing plate (or body), and the hinge that matches with pan (9,14).
Above-mentioned body, pressing plate, hinge can be lightweight constructions, as shell construction, hollow-core construction, also can adopt light-weight high-strength material such as aluminium alloy structure.
The utility model is installed in the ultra-high-tension power transmission line end that the preformed armor rods of the position of suspension clamp institute looping on the lead protects lines, the wire portion that protects lines end and vicinity thereof of transmission line is installed in the metallic channel of the present utility model, and make lead be cushioned the pad hold, with hinge body and pressing plate hinge are sold through joint efforts tightly then, and the lines termination is protected in encapsulation.
Said structure of the present utility model makes it have following tangible advantage and effect.
One, the utility model profile is spherical, the slick and sly bright and clean no wedge angle of peripheral surface, and anticorona discharge capability is strong.
Two, clamp pad of the present utility model adopts watt shape rubber blanket structure, and clamp is firm, is difficult for sliding.
Three, assembly of the present utility model is few, and all adopts symmetrical structure, and it is simple in structure, and is easily manufactured, adopts the hinge hinge of symmetry to connect structure, simple installation.
Four, assembly of the present utility model adopts lightweight construction, and it is economized with material, and is in light weight, and when particularly adopting aluminium alloy structure, its transmission of electric energy does not have magnetic hysteresis loss.
Below, use embodiment and accompanying drawing thereof again, the utility model is described in further detail.
Brief description of drawings.
Fig. 1 is the structural representation of a kind of transmission line anti-dizziness ball of the present utility model.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
A kind of transmission line anti-dizziness ball of the present utility model, as shown in drawings.Constitute by body, pressing plate, clamp pad, bearing pin.
Above-mentioned body 1 and pressing plate 2, its shape and structure are symmetrical, and its profile is hemisphere, and the combination back constitutes the prolate spheroid of similar rugby, and its two ends are the planar ends capitiform, adopt aluminium alloy structure.At central part along the spheroid long axis, the metallic channel that runs through spheroid is arranged, this metallic channel is the columniform cavity of ladder, and its larger-diameter macropore 3 is held in the mouth even with aperture 4 polyphones than minor diameter.Edge part at the body 1 of metallic channel one side has two end lugs 5 and 6, and its central part has pan, between the end lug 5 and 6 recess 7 is arranged, and the edge part of the pressing plate 2 of metallic channel homonymy has the middle lug 8 that matches with recess 7, and its central part has pan.All be coaxial line at three pans of the central part of above-mentioned three lugs and open system, with the aluminum cylindricality hinge 9 of common solid or hollow-core construction, insert in three pans, and the side hinge of body and pressing plate is unified into opening-closing structure.Opposite side at metallic channel has symmetrical lug pan structure, and promptly there is 1 middle lug at the edge of body 1, and there are two end lugs at the edge of pressing plate 2, and three lugs all have pan.
Above-mentioned clamp pad, be involutory by identical two watts of shape rubber blankets 10 and 11 of shape and form, be installed in the above-mentioned aperture 3 its outer surface and the driving fit of aperture inwall, the columniform boss 12 at its back side matches with the counterbore 13 at aperture 3 inwalls middle part, to prevent a watt shape rubber blanket slippage vertically.
During installation, be unified into the body 1 and the pressing plate 2 clamping power transmission lines of opening-closing structure with hinge, make preformed armor rods on the lead protect the lines end and place macropore 3 positions, and lead places watt inside portion of shape rubber blanket, close behind body and the pressing plate with another root hinge 14 identical with said structure, insert the pan of body and pressing plate opposite side, the lines end of protecting of its transmission line is encapsulated in the macropore 3, lead is gripped by watt shape rubber blanket 10 and 11 in the aperture 4, and the utility model is installed in the ultra-high-tension power transmission line.
Present embodiment can be installed on the ultra-high-tension power transmission line of 500KV, installs one and become and protect lines end envelope at the two ends that every group of preformed armor rods protects lines.Can be clamped at securely on the lead not can slippage, can prevent that preformed armor rods from protecting lines termination corona discharge, reduces electric energy loss, improves the circuit productivity effect, guarantees the safe operation of circuit.
