Abstract
The utility model relates to the technical field of electric power fittings and particularly relates to a pre-twisted damping spacer. The pre-twisted damping spacer of the utility model comprises a polygonal support frame and a plurality of wire clamps arranged on the polygonal support frame. Each wire clamp includes a connection block and a snap ring with one side open, wherein one end of the connection block is connected with the outer side wall of the opening of the snap ring, and the outer side of the snap ring is provided with a pre-twisted wire. The pre-twisted damping spacer is convenient to install, the installation time is saved by more than three times compared with that of a traditional product, and the construction safety is increased. The open pre-twisted wires have no eddy current loss and are more energy-saving, stability and durable grip strength between the spacer and a conducting wire are effectively improved, and the safety of a line is improved.
Description
Technical field
The utility model relates to the electric armour clamp technical field, particularly a kind of preformed damping conductor spacer.
Background technology
Conductor spacer is installed on the multiple fission conductor, guarantee that multiple fission conductor is under the impacts such as wind-force, ice load, conductor galloping and short circuit current, keep certain distance between the multiple fission conductor, avoid each other whiplash of sub-conductor, and have and suppress that wind shakes and the effect of subspan oscillation.Tradition self-damping conductor spacer fitting operation difficulty, operating efficiency is low, and conductor spacer produces sliding phenomenon easily on wire, and wire compression chord skewness is difficult to reach the effect that should have.
The utility model content
The purpose of this utility model is for the defective of prior art and deficiency, and a kind of compact conformation, easy to operate preformed damping conductor spacer are provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of preformed damping conductor spacer described in the utility model, comprise polygonal bracing frame and be located at some wire clamps on the polygon bracing frame, described wire clamp comprises the clasp of contiguous block and a side opening, and contiguous block one end is connected with the lateral wall of clasp opening, and clasp is provided with preformed armor rods.
Further, described clasp inboard is provided with skid resistant course.
Further, the described clasp outside is provided with holddown groove, and preformed armor rods passes holddown groove and is connected with clasp.
Further, described preformed armor rods is comprised of some parallel rigid structures that arrange in the shape of a spiral, and the screw diameter of preformed armor rods cooperates with bore in the clasp.
Further, bracing frame is provided with the anti-dance pre-manufactured hole.
The utility model beneficial effect is: the utility model is easy for installation, and the set-up time saves more than three times than traditional product, has improved the fail safe of construction; Open preformed armor rods is more energy-conservation without eddy current loss, effectively raises the stable and lasting grip between conductor spacer and wire, the fail safe that has improved circuit.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, preformed damping conductor spacer described in the utility model, comprise polygonal bracing frame 1 and be located at some wire clamps 2 on the polygon bracing frame 1, described wire clamp 2 comprises the clasp 22 of contiguous block 21 and a side opening, contiguous block 21 1 ends are connected with the lateral wall of clasp 22 openings, and clasp 22 is provided with preformed armor rods 3; Above-mentioned parts consist of the utility model agent structure.
Above-mentioned contiguous block 21 1 ends are connected with bracing frame 1 by bolt, the other end of contiguous block 21 all deviates from the center of bracing frame 1, the clasp 22 that arranges on preferred contiguous block 21 other ends of the utility model, clasp 22 adopts the U-shaped hatch frame, and one side of U-shaped opening is fixedly connected with contiguous block 21, angle between the center line of clasp 22U shape opening and bracing frame 1 and clasp 22 lines is less than 90 °, and then makes wire be subject to all the time the centripetal constraint restriction of conductor spacer when clasp 22 is interior.
Above-mentioned clasp 22 inboards are provided with skid resistant course 23, and skid resistant course 23 has certain elasticity, and wire directly contacts with skid resistant course 23 in clasp 22, and skid resistant course 23 can absorb the vibrations of wire, and for providing frictional force between wire and the conductor spacer.
Above-mentioned clasp 22 outsides are provided with holddown groove 24, and the preferred holddown groove 24 of the utility model is loop configuration, and holddown groove 24 adopts concentric setting with clasp 22; Preformed armor rods 3 penetrates and is arranged in the holddown groove 24 and the helical centre vertical spacer bars of preformed armor rods 3.
Above-mentioned preformed armor rods 3 is comprised of some parallel rigid structures that arrange in the shape of a spiral, preformed armor rods 3 places that holddown groove 24 is interior to carry out bidirectional screw to the wires in the clasp 22 and twine, the screw diameter of preformed armor rods 3 cooperates with the bore of clasp 22 and wire, so preformed armor rods 3 is intertwined and connected the wire of conductor spacer both sides by self rigidity helical structure.
Above-mentioned bracing frame 1 is provided with anti-dance pre-manufactured hole 11, can connect separately anti-dancing device on the anti-dance pre-manufactured hole 11, and then improves the Windproof anti-seismic performance that is connected between conductor spacer and the wire.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
