Abstract

A pre-stranded type spacer for a transmission line is composed of a supporting frame, a lead grip, a fastening piece, etc. The spacer can be conveniently installed on an overhead line and can effectively ensure the space between branch leads of the transmission line. Both the lead grip and the branch lead adopt a pre-stranded type structure. The pre-twisted type structure is composed of a body, a tile cushion and a pre-stranded wire, can effectively disperse stress, decrease the strain at the entry of the lead grip, reduce fatigue of the lead and protect the lead to ensure safe operation of the transmission line.

Description

Preformed conductor spacer

Affiliated technical field

The utility model relates to the conductor spacer of the protection gold utensil, particularly aerial condutor of superhigh pressure, UHV transmission line.

Background technology

The conductor spacer of existing aerial condutor, every phase conductor have adopted the bundle conductor of two to eight divisions.In order between wire harness, to keep specific distance, all want the installation interval rod at the lead certain distance, make the wire clamp of conductor spacer that every bundle lead is equidistant separately.Because the influence of meteorologic factors such as temperature, wind-force, conductor spacer should possess good suitable line grip force and suppress the premium properties of time retaining apart from vibration and aeolian vibration.

The chuck formula that conductor spacer wire clamp in the past all adopts, wire clip body (1) and pressing plate (2) are clamped lead by the form of a hinge (3).Need earlier wire clip body and pressing plate be compressed with specific purpose tool when installing on overhead transmission line, use pin (4) that pressing plate is pinned firmly then, the installation process complexity is not easy to grasp strength, and the accident of overexertion with wire clip body hinge position pressure break once takes 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.

Summary of the invention

Given this, the purpose of this utility model just be to provide a kind of easy for installation, solve conductor spacer stress and concentrate, and strengthen the preformed conductor spacer of the ability transmission line wire of conductor spacer antifatigue.

The technical scheme in the invention for solving the technical problem is:

The preformed conductor spacer of transmission line wire of the present utility model, comprise support frame (5), with support frame hinged and have therebetween damping piece preformed wire clamp (6), it is characterized in that above-mentioned wire clamp is evenly distributed on the circumference with equilateral form.

Form by body (7), watt pad (8), preformed armor rods (9) at wire clamp, the design of body (7) upper end has the wire casing of a semicircular in shape, in be lined with watt pad (8) and be used to the lead of packing into, every group of lead is fixed on sub-conductor on the body (7) by four preformed armor rodses simultaneously.

The beneficial effects of the utility model are:

1. the utility model adopts preformed armor rods clamping lead, and clamping length is big, and grip is even, prevents that wire clamp from producing damage to lead, and the lead grip evenly for the vibration of inferior retaining distance and because of lead reverses waving of forming, is had stable and inhibitory action; Adopt preformed armor rods clamping lead, directly install with the have gentle hands pine.

2. the utility model adopts preformed armor rods clamping lead, and installation process need not specific purpose tool, directly installs with the have gentle hands pine.

3. wire clamp and sub-conductor adopt the preformed armor rods structure, have disperseed stress effectively, have reduced the strain in wire clamp exit, have alleviated the fatigue of lead, have protected lead well

Embodiment

Embodiment 1

The preformed six division anti-dizzy type damping conductor spacers of a kind of transmission line of the present utility model, model: FJZY-645GH as shown in drawings, is made up of support frame (5), wire clamp (6), securing member etc.

Above-mentioned wire clamp (6), by body (7) watt pad (8) and preformed armor rods (9), cooperatively interact, be used for clamping six roots of sensation sub-conductor, and pass through securing member, wire clamp (7) and support frame (5) are connected and fixed, six roots of sensation sub-conductor is distributed on the circumference equidistantly.

Above-mentioned wire clamp (6) adopts the preformed armor rods structure with sub-conductor, has disperseed stress effectively, has reduced the strain in wire clamp exit, has alleviated the fatigue of lead, has protected lead well;

Present embodiment can be installed in 500 kilovolts and the above transmission line, with six corresponding clamping six strip wire harness of wire clamps difference, can effectively guarantee the transmission line sub-conductor at interval, can prevent the lead whiplash, wave, aeolian vibration and time span vibration, prevent the harmful effect of icing.

Claims

1. the preformed conductor spacer of a used for transmission line is made up of support frame, wire clamp, securing member etc., it is characterized in that: wire clamp is to be on the summit that equilateral is arranged in the conductor spacer periphery.

2. preformed conductor spacer according to claim 1 is characterized in that: wire clamp adopts the preformed armor rods structure, is made up of body, watt pad and preformed armor rods; Watt pad external diameter matches with body, and internal diameter matches with wire diameter; Preformed armor rods matches with wire diameter.
