Description
Technical field
What the preformed two division damping conductor spacers of the present invention related to is a kind of preformed electric power protection gold utensil, is applicable to two division damping conductor spacers of 330kV and following transmission line.
Background technology
The transmission line of China 330kV, single-phase routine all adopted the lead of two divisions.To keep particular distance between the lead in order making, to need the installation interval rod in some positions of lead, with conductor spacer that every bundle lead is equidistant separately.Owing to receive the influence of climatic factors such as wind-force, icing, temperature, conductor spacer must possess good intensity, suitable line grip force, suppresses the premium properties of subspan oscillation and aeolian vibration.
What traditional conductor spacer wire clamp all adopted is the chuck formula, and wire clip body and pressing plate are clamped lead through the form of a hinge.Need use specific purpose tool earlier wire clip body and pressing plate to be compressed when on overhead transmission line, installing, pin pressing plate firmly with pin then, the installation process complicacy is not easy to grasp.The accident of overexertion with wire clip body hinge position pressure break once took place.Simultaneously, form stress easily and concentrate, have a strong impact on the performance of lead because wire clamp is not wide, and the clamping conductor side is narrow, especially very big to high height above sea level, the influence of heavy icing area transmission line, cause accidents such as the disconnected thigh of lead easily.Traditional conductor spacer is owing to be pair frame structures, more complicated again, and relevant parts are more various, and material is more various, and main material is an aluminium alloy, cost compares higher.Aluminium alloy has increased the danger of circuit operation virtually because the low recessiveness with casting flaw of its intensity exists.
Summary of the invention
The object of the invention is exactly to above-mentioned weak point, and a kind of preformed two division damping conductor spacers are provided, and is the two division conductor spacers that a kind of installation is simple, damping is good, easy for installation, price is lower.
The preformed two division damping conductor spacers of the present invention are to take following technical scheme to realize to be:
Preformed two division damping conductor spacer comprises framework, damping portion, wire clamp.Damping portion is equipped with at the framework two ends respectively, and wire clamp is installed on the damping portion.Realize being connected of conductor spacer and lead through preformed armor rods fixing clamper head.And the wire clamp head contacts the place and is coated with rubber layer with lead, prevents because the long-term aeolian vibration wire clamp wearing and tearing of circuit lead.The wire clamp afterbody is provided with the spacing elliptical aperture of damping rubber circle, and the connecting bolt circular hole is worn in the centre.Damping portion is made up of teabowl with a cover, damping rubber.Teabowl with a cover is provided with the connecting bolt installing hole, and side is provided with two teabowl with a cover mating recesses and boss, and side top is provided with the wire clamp stopper slot, with its restriction wire clamp rotational angle.The teabowl with a cover downside is provided with the framework connection bump, is provided with the framework connecting hole above.The framework bilateral symmetry is provided with installation base before and after every side head.
Damping portion is made up of two teabowls with a cover, two damping rubbers, and is simple and convenient.Being connected of wire clamp and framework is to be enclosed within on the installation base of framework through the square hole on the teabowl with a cover, and two teabowl with a cover mirror images cooperate to be installed, and relies on connecting bolt that two teabowls with a cover are fastened on the framework.Conductor spacer wire clamp between two teabowls with a cover is fixed through two damping rubbers, and connecting bolt is fastening, realizes damping simultaneously.The movable scope of slot opening restriction wire clamp on teabowl with a cover side top.Two wire clamp symmetries of a whole set of conductor spacer are installed.
Operation principle:
The present invention realizes fixing with being connected of lead through the preformed armor rods fixing clamper.The place that the wire clamp head contacts with lead is coated with rubber layer, prevents because the long-term aeolian vibration wearing and tearing of circuit lead.The aeolian vibration of transmission line drives two wire clamps and vibrates together; Wire clamp receives twisting resistance apart from swinging back and forth with respect to framework; The oval damping rubber that the wire clamp afterbody the connects power strain that suffers oppression, the portion of energy of buffering vibration and absorbed oscillation realizes the vibration-isolating effect of conductor spacer.The movable scope of slot opening restriction wire clamp on teabowl with a cover side top makes conductor spacer be unlikely to stressed excessive being damaged.
The beneficial effect of the preformed two division damping conductor spacers of the present invention is:
1, the present invention fixes through preformed armor rods, and preformed armor rods has outstanding anti-fatigue performance, can block the slippage of the wire clamp left and right sides, and slippage influences vibration-isolating effect because connecting bolt is loosening with regard to having prevented conductor spacer effectively like this.
2, the present invention adopts single plate structure, and framework and teabowl with a cover all adopt cast steel, reduces cost and improves intensity again.
3, damping portion of the present invention adopts damping rubber, teabowl with a cover, wire clamp.Through the fastening force of connecting bolt, compress two teabowls with a cover and merge together, thus the compressing rubber fixing clamper.The product assembling is simple and convenient, and damping is good.
4, wire clamp of the present invention top layer is rubber-coated, and the modified line folder is soft contact with hard contact of lead, and at utmost the guardwire top layer is not worn.
