Abstract
A pre-twisted spacing rod is characterized in that the pre-twisted spacing rod comprises a supporting rod and two wire clips arranged at two ends of the supporting rod; the wire clip is provided with a clamping trough; the wire clip is provided with a through hole which is arranged along the extension direction of the clamping trough; and the through hole is internally provided with a pre-twisted wire in a penetrating manner. The pre-twisted spacing rod has reasonable structure design, can effectively eliminate the interactive force between the spacing rod and a leading wire, can reinforce the effective holding force of the spacing rod on the leading wire, can complete the installation of the spacing rod manually by simple and quick construction type, can be replaced quickly, has no external force damage on the leading wire, and is extremely suitable for high-attitude operation. The damping structure of the pre-twisted spacing rod effectively counteracts the impact force of the wind pendulum on the leading wire, greatly reduces the vibration frequency and provides reliable guarantee for the safe running of the line.
Description
Technical field
The utility model belongs to the escapement of the aerial condutor maintenance wire pitch of transmission line, is specifically related to easy for installation to the undamaged preformed conductor spacer of lead.
Background technology
According to overhead power line conductor spacer technical conditions and test method, on the transmission line aerial condutor, need to install inter-phase spacer, on the installation site, should keeping the reasonable numerical value of multiple conducting wires spacing, and make lead keep certain safe distance to prevent contacting naturally between lead between the conductor spacer; This requires conductor spacer can resist the mechanical load that is applied in installation process, and keeps and satisfied (comprising short-circuit conditions) requirement, takes place to destroy and permanent deformation without any member; And under the service conditions that requires, avoid single conductor to destroy, there are not unacceptable corona and radio interference; Be suitable for simple and safe installation, when operation, guarantee that each part is not loose; The ability that under the situation of no conductor spacer and single conductor destruction, dismounting is again arranged and install again; And in the temperature range of whole work, guarantee its basic function and avoid noise jamming.
The wire clamp of existing conductor spacer all generally adopts bolt or other fastening means, make the terminal operation between wire clamp and lead need adopt special conductor spacer spanner just can realize, but moment of torsion is crossed the damage that conference causes lead or bolt, and moment of torsion is too small then can to make the grip between lead and stockbridge damper can not be up to standard.Even use the torque wrench construction, the grip between stockbridge damper conductor spacer and lead reaches standard.Wire clamp can cause the concentration of local of lead stressed simultaneously, influences the performance of lead.
The utility model content
The utility model provides a kind of reasonable in design, changed connected mode between traditional conductor spacer and lead, improve the preformed conductor spacer of the stress performance between conductor spacer and lead, it can be by the free-hand installation of finishing conductor spacer of quick and easy form of construction work, and can change fast, to the lead not damaged, be fit to very much the work high above the ground of transmission line simultaneously.
The technical scheme that the utility model adopted is as follows:
A kind of preformed conductor spacer is characterized in that described preformed conductor spacer comprises support stick, the wire clamp that the support stick two ends are provided with, and described wire clamp is provided with clip slot, offers the through hole that is provided with along the clip slot bearing of trend on this wire clamp, wears pre-wire in the described through hole.
Concretely, described clip slot is a groove that cooperates with the conducting wire, and described through hole is the slit in a V-type cross section.
Among one embodiment, flexibly connect between described wire clamp and described support stick, make the wire clamp can be around the rotational of support stick.
Described preformed armor rods activity is located in the described through hole.
Among one embodiment, the middle part of described preformed armor rods wears and is fixed in the described through hole.
Among another embodiment, described preformed armor rods is the winding displacement of aluminium Baogang material.
Among the embodiment, described support stick is one or intersects many that fixedly install that the end of each support stick is provided with wire clamp again.
The end of described clip slot and support stick all is provided with damping buffering mechanism.
This preformed conductor spacer need not any instrument when installing and remove, only need preformed armor rods is passed the through hole that is provided with on the wire clamp, and with the clip slot of wire clamp to positive conductor after, preformed being wrapped on the lead got final product.The wire clamp of conductor spacer can be dispersed in grip on the conductor area of certain-length uniformly by preformed armor rods and lead, has avoided the stress of lead to concentrate.Adopt that the preformed armor rods of high-strength aluminium Baogang material has more effectively guaranteed to continue between preformed armor rods and lead, stable, grip reliably.The installation quality of this preformed conductor spacer can be in order to carrying out ground observation and judgement by telescope in addition, thus greatly the reduction of degree acceptance of work difficulty and cost, and improved the examination reliability.
The beneficial effects of the utility model are, the reasonable in design of this preformed conductor spacer, can effectively strengthen the grip between conductor spacer and lead, improve the stress performance between conductor spacer and lead, it can be by the free-hand installation of finishing conductor spacer of quick and easy form of construction work, and can change fast, simultaneously to the lead not damaged, be fit to very much the work high above the ground of transmission line.
Description of drawings
Fig. 1 is the perspective view of the utility model embodiment.
Embodiment
As shown in Figure 1, this preformed conductor spacer is mainly by support stick 10, the wire clamp 20 at support stick two ends and preformed 23 is formed, the wire clamp that the support stick two ends are provided with, wire clamp is provided with clip slot 22, and the clip slot inner surface is provided with the damping pad, offers the through hole 21 that is provided with along the clip slot bearing of trend on this wire clamp, activity wears pre-wire in the through hole, and this preformed armor rods 23 is the winding displacement of aluminium Baogang material.Wire clamp 20 adopts aluminum alloy materials to make, and clip slot 22 is a groove that cooperates with the conducting wire, and through hole is the slit in a V-type cross section.Flexibly connect between wire clamp and support stick and can be undertaken spacingly, make the wire clamp can be around the rotational of support stick by the spacing preiection 11 that is provided with on the support stick.
During installation, preformed armor rods is positioned over the middle part of wire clamp, the clip slot of two wire clamps is cooperated aligning with lead, then with the preformed armor rods at two ends, the left and right sides evenly being wrapped on the lead of nature get final product.
