Abstract

The utility model discloses an anti-galloping line-stabilizing pipe which comprises a long pipe sleeved on a high-voltage line. Two ends of the long pipe are respectively provided with a limit baffle plate. The long pipe is composed of two or more sectional pipes connected through connectors. According to each sectional pipe, two valved pipes are combined through two tightening rings to form a circular pipe, wherein one side of one valved pipe is provided with an aluminum strip to cover the edge of the valved pipe. As the anti-galloping line-stabilizing pipe provided by the utility model has a certain weight, a burden is imposed on anti-galloping of a lead, and the anti-galloping line-stabilizing pipe plays a certain role in anti-galloping effect. The internal diameter of the anti-galloping line-stabilizing pipe is greater than the external diameter of an electric wire. Thus, the anti-galloping line-stabilizing pipe can freely rotate on a lead to make torsional rigidity of the lead close to zero. The lead is easy to twist under the action of eccentric icing, an icing fracture surface is nearly round, a wing-shaped section will not be formed, and lift force will not be generated under the action of wind excitation. Thus, the anti-galloping line-stabilizing pipe plays a certain role in anti-galloping effect.

Description

The steady spool of anti-dance

Technical field

The utility model relates generally to power domain, is specifically related to the steady spool of a kind of high-tension bus-bar anti-dance.

Background technology

It is the key factor that threatens transmission line safe operation that high-tension bus-bar is waved.The harm of waving generation is many-sided, such as tripping operation, wire electric arc burn, gold utensil damage, disconnected strand of broken string of wire, the tower etc. that falls.Wave and can cause into great economic loss and social influence.In recent years, all there is excessively serious waving in the areas such as China northeast, North China, Central China, northwest, its scope wide, intensity is big, loss be heavily that history is rare, therefore, extremely amass and effectively carry out that to wave preventing and controlling imperative.But, and the anti-dance device of people's development at present often only lays particular emphasis in a certain respect, therefore, anti-dance effect is not very best.

utility model contenttechnical problem to be solved in the utility model is: the first, because the steady spool of anti-dance is the device that can freely rotate on wire, so not-easy-to-freeze, be difficult for accumulated snow, if produced icing, under eccentric icing effect, steady spool very easily twists, make that icing is rounded does not become aerofoil section, therefore, under wind incentive action, can not produce lift, eliminate a factor of conductor galloping.The second, the steady spool that has a constant weight has increased burden to conductor galloping.Three, the anti-dancing device of the steady spool comparison of anti-dance capitate, its physical dimension is pressed close to wire most, like this, can cut down in design mutually or nargin that phase spacing leaves the investment of having saved wire shaft tower.Four, the wire condition of dancing, wire should be able to free bend, could wave by waviness; If wire is managed boundary by a segment length, harden, wire is danced and is restricted.

In order to solve above technical problem, the technical solution of the utility model is:

The steady spool of a kind of anti-dance, it is characterized in that: include the segment length's pipe being sleeved on high-tension bus-bar, long tube two ends respectively arrange a spacing shelves dish, described long tube forms one by two or more minutes pipe joints by connector, within each minute, pipe joint is combined into pipe by two effective two lock ring rings of lobe, and wherein dress aluminum strip in one side of a lobe pipe covers the edge mouth of this lobe pipe.

The steady spool of described anti-dance, is characterized in that: described long tube internal diameter should be slightly larger than high-tension bus-bar external diameter, guarantees that long tube is free to rotate on electric wire.

The steady spool of described anti-dance, is characterized in that: described connector is comprised of dovetail key and dovetail groove two elements, and is loaded on respectively the lobe pipe end of docking.

The steady spool of described anti-dance, is characterized in that: the main body of described long tube is that can to take iron and steel be material to per minute pipe joint two lobe pipes.

The steady spool of described anti-dance, is characterized in that: described lobe pipe and aluminum strip are fixed by screw.

The steady spool of described anti-dance, is characterized in that: the screw of described spacing block plate, connector, lock ring ring and dress aluminum strip is the stainless steel material of pure austenite structure.

The beneficial effects of the utility model are:

A, because the steady spool of anti-dance can freely rotate on wire, so the torsional rigidity of the steady spool of anti-dance on wire is almost nil, at eccentric icing effect lower wire, easily there is very large torsion, icing is approached circular, can not form aerofoil section, therefore, can not produce lift and moment of torsion because wind excitation makes wire, reduce conductor galloping factor.

Thinking highly of in order to increase the burden of conductor galloping of B, the steady spool of anti-dance self, does not allow wire easily dance.

C, conductor galloping are because wire forms due to unrestrained ripple, and the steady spool of anti-dance makes a section lead stiff and can not free bend, stops wire wave ripple to be advanced, and has reduced conductor galloping factor.

D, the anti-dancing device of the steady spool comparison of anti-dance capitate, its physical dimension is pressed close to wire most, like this, can cut down in design mutually or nargin that phase spacing leaves the investment of having saved wire shaft tower.

Embodiment

The utility model general structure as shown in Figure 1, the steady spool of a kind of anti-dance, lobe pipe 3 and the synthetic pipe of lobe pipe 4 by thering is the common iron and steel iron of constant weight and certain length, made, high-tension bus-bar 1 is placed in pipe, two lobe pipes press from both sides an aluminum strip 5 therebetween when combination, described aluminum strip 5 is by rust steel screw and 4 combinations of lobe pipe of pure austenite structure, the steady spool internal diameter of anti-dance is greater than electric wire external diameter, therefore pipe can freely rotate on wire, above-mentioned two lobe pipes 3 and 4 are by bolted by the rust steel two halves lock ring ring 6 of pure austenite structure.Common one section of steady spool of anti-dance is comprised of two joints or the above pipe of two joints, between every joint by being connected to the rust steel dovetail key 7 of the pure austenite structure on lobe pipe separately and dovetail groove 8 is chimeric is integral.At the one section of steady spool of anti-dance two ends, respectively fill the spacing block plate 2 of rust steel of a pure austenite structure, fix the position of this section of pipe on wire.The structure and material of the steady spool of dance as above is in order not form closed magnetic circuit on wire.

The implementation process of such scheme is as follows:

Staff can be on the ground first combined into complete semicircle by aluminum strip 5 by the rust steel screw of pure austenite structure and the lobe pipe 4 of semicircle not, as shown in Figure 2.The dovetail key as shown in Fig. 3 a, 3b or the lobe pipe of dovetail groove needs installation, use screw and dovetail key or dovetail groove fastening at lobe tube end respectively again.

Staff climbs up shaft tower with material, along wire, arrive and need the dress steady spool of anti-dance position, with with the lobe pipe 3 of aluminum strip with the lobe pipe 4 of aluminum strip, wire not being combined in and being wherein combined into complete pipe, then near place, both ends, each is reinforced two lobe pipes with bolt with lock ring ring as shown in Figure 4 at every pitch circle pipe.Between every joint and every joint, with dovetail key, embed dovetail groove and be combined into one, as shown in Figure 1.

For guaranteeing the desired location of the steady spool of anti-dance on wire, on the wire at the one section of steady spool of anti-dance two ends, each is fastened on two halves dish on wire with bolt with spacing block plate as shown in Figure 5, but spacing block plate can not be dead the steady line tube clip of anti-dance, allow the steady spool of anti-dance on wire, freely rotate.
