Description
Technical field
The utility model relates to the electric power transportation art, especially relates to a kind of electric armour clamp, the strain clamp that is specifically related in a kind of overhead transmission line and on transformer station's shaft tower the carbon fiber lead is connected, fixes, strains.
Background technology
Strain clamp be in the overhead transmission line and transformer station's shaft tower on to lead connect, the electric armour clamp of fixing, tension.At present, domestic transmission line all adopts steel core, aluminium stranded conductor, steel reinforced aluminium conductor, and the one, be easy to generate magnetic hysteresis and damage consumed power; The 2nd, contact-making surface is less, and it is uneven to peg graft, and is prone to heating, and grip is unstable; The 3rd, through explosion crimping,, reduced mechanical strength because strong wallop has changed metallographic, it is dangerous to construct.At present in processes such as electric network reconstruction, overhead transmission line, the extensive use of carbon fiber lead.But because the carbon fiber wire quality is light, quality is crisp; Under the uneven situation of radial force, be prone to the carbon fiber lead is caused damage; Even cause the fracture of lead; Thereby reduced the bearing capacity of carbon fiber lead composite core along the line direction, at present common strain insulator gold utensil can not satisfy the connection of carbon fiber lead on the tower bar, fixing, tension, etc. requirement, have that length is long, construction is inconvenient, problem such as inconvenience be installed.At first to file 200820136586.4 " polymer alloy high energy-saving strain clamp ",, with regard to its workpiece weight and cost, do not reach desirable degree as yet though on practical applications, receive very good effect.In addition, the strain clamp that existing overhead power transmission conducting wire uses has only the effect that connects the traction lead, receives wind-force easily and swings, and also receives clammy weather to form icing easily, and then causes transmission line galloping.
Summary of the invention
For solving problems such as the connection of carbon fiber lead on the tower bar, fixing, tension.The purpose of the utility model is to provide that a kind of grip is bigger, high temperature resistant, water conservancy diversion is effective, easy for installation; Can satisfy the strain clamp that the carbon fiber lead requires the connection of lead, fixing, tension etc. on shaft tower; And through changing original strain clamp profile, to reduce windage; Change strain clamp icing profile, aerodynamic profile when changing the strain clamp icing, and then reduce the transmission line galloping probability and reduce the transmission line galloping amplitude.
To achieve these goals, the technical scheme of the utility model is:
A kind of carbon fiber conductor strain clamp mainly draws anchor to connect inner cone external screw thread core retainer plate, outer cone elasticity sandwich, lining, sleeve pipe successively by internal thread and forms overall structure; It is that the right side is connected with half hollow cylinder of crimping telescopic chute, internal thread at the flat-shaped draw ring of circle retaining left side connecting band long through-hole that internal thread draws anchor; Sleeve pipe is the tubular body of hollow via-hole, and one of which end outside is provided with video disc; Draw half hollow cylinder internal thread of anchor to connect one through internal thread and be provided with inner cone, externally threaded core retainer plate; The outer cone elasticity sandwich that connects a hollow in the middle of the inner cone external screw thread core retainer plate, this sandwich be through locking carbon fiber lead composite core, thereby connect, fixed carbon fiber lead; The inner cone of inner cone external screw thread core retainer plate is identical with the outer cone tapering of outer cone elasticity sandwich, is 0.5～15 degree; It is characterized in that, the strain clamp outside of sleeve have around barber-pole stripes; Said internal thread draws anchor to adopt austenitic steel to process.
Make carbon fiber lead composite core pass outer cone elastic clip in-core portion,, outer cone elasticity sandwich and inner cone external screw thread core retainer plate are clamped automatically through radial effect power; Locking lead composite core; Internal thread draws anchor that the crimping telescopic chute is set simultaneously, and inner cone external screw thread core retainer plate one end is placed lining, and sleeve pipe is through hydraulic pressure; Lead is connected, is fixed on the carbon fiber conductor strain clamp, finally draw anchor that the carbon fiber lead is connected, is fixed on the shaft tower through internal thread.
Because of carbon fiber lead light weight property crisp, can only radial force, in installation process, distortion, bending etc. will damage lead easily, make its fracture, the utility model outward appearance length is calculated and checking through science, novel structure is reasonable in design, stability is strong, guardwire.Composite core through outer cone elasticity sandwich, inner cone external screw thread core retainer plate locking carbon fiber lead can clamp composite core automatically, fix through radial effect power.Internal thread draws anchor one end that internal thread is set, and the surface is provided with the crimping telescopic chute, novel structure, and design science, stable performance, internal thread draws anchor to connect inner cone external screw thread core retainer plate, and the one of which end is provided with swivelling chute, and convenient the installation is convenient to construction.Inner cone external screw thread core retainer plate outer setting crimp groove, internal diameter are served as reasons thin to thick conulite, and be highly polished, matches with outer cone elasticity sandwich.
Outer cone elastic clip in-core portion is provided with centre bore, is installed with the lead composite core, and is highly polished; External diameter is served as reasons and is carefully arrived thick cone, and relative intersection evenly is provided with 4-6 telescopic chute at its two ends respectively, makes it when inner cone external screw thread core retainer plate inner radial is stressed, clamp composite core, locks lead, thereby plays the effect of connection, fixing cord.Said internal thread draws anchor to adopt austenitic steel to process, and makes that its intensity is bigger, and is more corrosion-resistant.
Advantage such as the utlity model has novel structure, design science, good guide performance, stability is strong, grip is stable, cost is lower, construction install convenience, labour intensity are low.In addition, have in the strain clamp body outside around barber-pole stripes, the aerodynamic shape at this strain clamp position of spiral-shaped change, the wind-engaging cross section that strain clamp is gone up along its length constantly changes; Can also make under clammy weather that the icing profile is irregularly shaped outside the strain clamp; The cross section is changed along the hand of spiral; So that mutual interference of aerodynamic effects phase and restriction that wind-force produced, thus the condition of dancing destroyed: and its lift coefficient is reduced, and the lift coefficient curvilinear motion tends to be steady; The increase of its resistance coefficient can make lead in motion process, consume more energy, helps reducing the transmission line galloping probability and reduces the transmission line galloping amplitude.Owing to adopted such scheme, make the utility model in use, can reduce windage, and reduce the transmission line galloping probability and reduce the transmission line galloping amplitude.
