Abstract
The utility model relates to a reinforced type hanging cable clamp for a high-intensity steel-cored aluminum alloy strand cable of an extra-high voltage heavy ice area power transmission line, which is used to lift wires on a power transmission line, and comprises a cable clamp main body, a cable clamp pressure plate, a suspended hanging plate, a connecting bolt and a securing member and the like. Wires in a heavy ice area have big load, high voltage, outstanding corona problems, big grip strength required by a matching cable clamp and big load. The reinforced type hanging cable clamp has high intensity, which has enough grip strength to wires, and has strong anti-corona capability to high attitude heavy ice areas. The reinforced type hanging cable clamp has enough mechanical intensity and excellent electric property, which can guarantee the safe operation of high-voltage heavy ice area lines.
Description
Affiliated technical field
The utility model relates to a kind of used for transmission line suspension clamp, relates in particular to the reinforced suspension clamp of a kind of high strength steel core aluminium alloy stranded conductor.
Background technology
It mainly is to rely on transmission line to finish that present electric power is carried, and twisted wire is installed in that direct-connected equipment mainly is suspension clamp, strain clamp etc. on the iron tower.Twisted wire is guided and supported in the effect of suspension clamp exactly on tangent tower, string links to each other with the cross-arm of shaft tower through dangling.
Enforcement along with domestic transferring electricity from the west to the east, the construction of high height above sea level, heavy icing area, UHV transmission line at a distance,, its lead adopts heavy in section high strength steel core aluminium alloy stranded conductor more, and supporting with it suspension clamp requires big grip, big load, high strength, anticorona.Because aluminum steel part load is bigger, the domestic class formula steel core aluminium alloy stranded conductor strain insulator situation that grip can't meet the demands that continues that once occurred.General suspension clamp can only bear less relatively vertical load and less grip at present, be applicable to the twisted wire of ordinary lines footpath and intensity, the grip that suspension clamp provides can't satisfy the requirement of strength of heavy in section high strength steel core aluminium alloy stranded conductor, can not guarantee the normal use on ultra high voltage heavy icing area transmission line.
Summary of the invention
Given this, the purpose of this utility model just is to provide a kind of the satisfy extra heavy ice formation of ultra high voltage transmission line, the reinforced suspension clamp of high strength steel core aluminium alloy stranded conductor, has big grip, big load, high anticorona performance.
The technical scheme in the invention for solving the technical problem is:
The reinforced suspension clamp of extra heavy ice formation transmission line high strength steel core aluminium alloy stranded conductor of the present utility model is made up of suspension clamp body (1) and suspension clamp pressing plate (2), the link plate that dangles (3), half-round head square neck bolt (4), securing member (5) five parts.Wire clip body and pressing plate all adopt high-strength aluminum alloy die casting to form.Wire casing is to be synthesized by slick and sly connection of two sections circular arcs in suspension clamp body (1) hull, the suspension clamp blade outlet angle of dangling is freely changed from 0 ° ~ 25 °, wire clip body can rotate flexibly around the trunnion axis vertical with lead, guaranteed that steel core aluminium alloy stranded conductor and suspension clamp body wire casing have the excellent contact face, avoided the concentrated infringement of compression lead.The suspension clamp outlet is the slick and sly lip of big R, the profile rounding off.The wire casing of the wire casing of pressing plate (2) and body (1) adapts, and body (1) and pressing plate (2) are packed into fastening with four M18 half-round head square neck bolts (4) behind the lead, has improved the grip of wire clamp greatly.
The beneficial effects of the utility model are:
1. the utlity model has enough intensity, can bear bigger vertical load.Wire clamp main body, pressing plate adopt the high-strength aluminum alloy material casting technique to form, and foundry goods is heat-treated, and are different from traditional in the past fine aluminium material casting.Wire clamp is shaped to streamlined handbag type, and the whole load-carrying construction of triangle has improved the intensity of wire clamp, failure load up 210kN greatly.
2. the utility model has enough grips to high strength steel core aluminium alloy stranded conductor.Wire clip body and pressing plate wire casing are to be connected to form by two sections circular arcs (6) slyness, and the angle of dangling of suspension clamp is 0 ° ~ 25 °, and wire clip body can rotate flexibly around the trunnion axis vertical with lead, adapt to lead different variation on transmission line better; Have enough even contact surfaces with lead, avoid the concentrated infringement of compression lead; Body (1) and pressing plate (2) are fastening with four M18 half-round head square neck bolts (4), have improved effective screwing force distance of bolt greatly than U-bolt commonly used, and wire clamp increases the lead grip, and grip surpasses 60kN.
3. the utlity model has strong anticorona ability.Be used for UHV transmission line, during 2500 meters height of height above sea level, the anticorona performance of self tool.The wire casing outlet of wire clip body (1) connects for typhon degree of lip-rounding circular arc is slick and sly, big R outlet lip, and wire clamp pressing plate (2) and half-round head square neck bolt (4) make the good anticorona ability of wire holder in wire clip body (1) wire casing inner shield.

Embodiment
The reinforced suspension clamp of a kind of transmission line high strength steel core aluminium alloy stranded conductor of the present utility model, model: CGF-21TGZ, as shown in drawings, form by suspension clamp body (1) and suspension clamp pressing plate (2), the link plate that dangles (3), half-round head square neck bolt (4), several parts of securing member (5).
Above-mentioned suspension clamp body (1) suspension clamp pressing plate (2) is packed into behind the lead, and is fastening with four single-column button-headed bolts, is connected on the string that dangles by the link plate that dangles (3) to be used to guide and support lead.，
The heavy icing area that present embodiment can be installed in the above grade power transmission and transformation line of 500kV uses with high strength steel core aluminium alloy stranded conductor, can satisfy the load and the grip requirement of suspension clamp, the anticorona requirement of high height above sea level heavy icing area is easy to install, thereby guarantees the safe operation of transmission line.
