Abstract
The utility model provides a pre-twisted connection strip for strengthening a connection tube. The connection strip comprises at least four groups of pre-twisted wires, each group of the pre-twisted wires is composed of a plurality of aluminum alloy wires, clamping sections located at two ends of each group of the pre-twisted wires and a current guiding section at a middle part of each group of the pre-twisted wires form each group of the pre-twisted wires, each group of the pre-twisted wires of the current guiding section is used to clamp the connection tube, the pre-twisted wires of the current guiding section are arranged at intervals to each other, and each group of the pre-twisted wires of the clamping sections are used to wind leads at two ends of the connection tube to fix the leads. The pre-twisted connection strip, provided by the utility model, for strengthening the connection tube can provide a stable and enduring holding force for the leads or earth leads, compensates the creep deformation and the plastic deformation well, and improves the anti-fatigue performance of the leads; and construction tools are not needed when the installation construction is carried out, the working efficiency can be greatly improved, and the labor intensity of workers is reduced.
Description
Technical field
The utility model belongs to electric field, particularly a kind of preformed connection strip for strengthening connection tube.
Background technology
In current power circuitry engineering is built, for convenience of construction, adopt in a large number the detonation pressure technology that continues.But external form is obviously irregular after this technology crimping, still do not have up to now effective detection method to detect its crimp quality and intensity, make crimp quality be difficult to control, cause the unstable of crimp strength and electrical connection.This is also the serious potential safety hazard that at present a lot of working lines exist.For making the detonation pressure circuit safe operation that continues, generally take that original detonation pressure splicing sleeve is changed to crimp quality and intensity is easy to the hydraulic pressure splicing sleeve detecting.Do like this and must get rid of one section of electric wire, cause wire length inadequate, the parameter such as tension force, sag of former circuit is changed, and to existing operation shaft tower effect impact load (adopt detonation pressure continue the overhead line structures load of technology can not meet new criteria and require), can seriously jeopardize the safe operation of circuit, cause change lead, ground wire, gold utensil etc., cost increases, interruption duration increases.
Meanwhile, also there is the too high situation of temperature rise in traditional electric armour clamp.According to a large amount of infrared detection results, in high-tension line, the thermal defect of line hardware is more, concentrates on the mechanical connecting part such as strain clamp, quabernary fission tripartition connection baffler, jumper clamp, splicing sleeve.According to incompletely statistics, the whole nation every year because splicing sleeve is aging, the poor gold utensil heating causing of installation quality, accident that wire goes offline be at up to a hundred, has a strong impact on the safe operation of circuit.
Utility model content
For defect of the prior art and deficiency, the purpose of this utility model is to provide a kind of simple installation, grip is continual and steady, energy-efficient, adhesive force is evenly distributed, through-current capability is strong preformed connection strip for strengthening connection tube.
In order to achieve the above object, the utility model proposes a kind of preformed connection strip for strengthening connection tube, comprise at least four group preformed armor rodses, described every group of preformed armor rods is comprised of at least two preformed armor rodses, every preformed armor rods is comprised of some aluminum-alloy wires, described every group of preformed armor rods is by being positioned at the clamp segment at its two ends and the diversion section at middle part forms, every group of preformed armor rods of described diversion section is used for clamping splicing sleeve and interval setting each other, and the wire that every group of preformed armor rods of described clamp segment is used for being wound around splicing sleeve two ends is to be fixed.
Preferential as technique scheme, described every group of preformed armor rods two ends end face presents circular-arc.
The preformed connection strip for strengthening connection tube the utility model proposes, can be to leading () line provides stable and lasting grip, fine the creep of wire, plastic deformation are compensated, improve the fatigue performance of wire, and, when installation, without construction tool, operating efficiency can be provided greatly and reduce workman's labour intensity.
Accompanying drawing explanation
Fig. 1 is the utility model preferred embodiment structural representation;
Fig. 2 is that the utility model preferred embodiment is used status architecture schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
The utility model preferred embodiment as shown in Figure 1, comprise at least four group preformed armor rodses, described every group of preformed armor rods is comprised of at least two preformed armor rodses, every preformed armor rods is comprised of some aluminum-alloy wires, described preformed armor rods is that high-strength aluminum alloy silk is made, be used in and lead () periphery of line splicing sleeve, original splicing sleeve is carried out to the reinforcement of mechanical performance and electric property, prevent because of the problem of splicing sleeve lead () accident that comes off of line occurs, described every group of preformed armor rods is by being positioned at the clamp segment 1 at its two ends and the diversion section 2 at middle part forms, play respectively the effect of hold with a firm grip wire and drainage, every group of preformed armor rods of described diversion section is used for clamping splicing sleeve and interval setting each other, and the wire that every group of preformed armor rods of described clamp segment is used for being wound around splicing sleeve two ends is to be fixed.
Described every group of preformed armor rods two ends end face presents circular-arc, and described preformed armor rods is high-intensity aluminum-alloy wire, hank knotting end rounding, prevents corona, energy-efficient, has good environment tolerance.
This device is when installing and using, as shown in Figure 2, first preformed connection strip for strengthening connection tube diversion section to be placed on to the centre of splicing sleeve, then by preformed connection strip for strengthening connection tube clamp segment, the direction along preformed armor rods spiral is wrapped in respectively on the wire of splicing sleeve both sides, other is respectively organized hank knotting and is arranged on wire by same method, completes the installation of the preformed connection strip for strengthening connection tube of preformed armor rods.It is without any need for instrument, convenient and swift when it is installed.And, by preformed armor rods, providing stable, lasting grip and strong through-current capability, the situation of effectively having avoided temperature rise too high, tired disconnected thigh in wire-connection place to come off occurs.
Certainly; the utility model also can have other embodiment; in the situation that not deviating from the utility model spirit and essence thereof; person of ordinary skill in the field is when making various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of claim of the present utility model.
Claims (2)
