Abstract
The utility model discloses a carbon fiber composite core wire strain clamp for an electrical power system to fix carbon fiber composite core aluminum stranded wire on an aerial electrical power circuit and a transformer station tension tower, and is formed by arranging a wedge clamping holder inside a clamp body, a wedge clamp with the shape corresponded with the inner hole of the wedge clamp inside the clamping holder, and an additional inner pipe. By utilizing the characteristic that the wedge clamp moves inside the clamping holder fully, the utility model reliably clamps the carbon fiber composite core under the change of temperature, firmly carries out pressure welding on the inner pipe with the clamp body and the aluminum stranded wire to form a conductor without any damage to the carbon fiber composite core. The utility model has the advantages of compact and reasonable design, novel and clever idea, small temperature infection, strong anti-vibration fatigue resistance, adequate holding power distribution and strong bearing holding force, and avoiding the relaxation of the holding force effectively, etc. The utility model reduces the economy loss without exchanging the steel tower and damaging the green area on the condition of the capacity growth of the system, which is economic and practical. The utility model has extensive development prospect, and is suitable to be popularized and applied.
Description
Technical field:
The utility model relates to a kind of fixedly strain clamp of steel reinforced aluminium conductor that is used on overhead power line and the electric substation's strain insulator shaft tower in electric power system.
Background technology:
Strain clamp is the gold utensil that is used for fixing cord on overhead power line and the electric substation's strain insulator shaft tower in the electric power system, it is connected lead with insulator string, insulator string is connected with iron tower again, pulling force with the carrying lead, reduce the sag of lead, crucial effect is played in the safe operation of electric power system.For a long time, described lead all adopts steel reinforced aluminium conductor, because steel reinforced aluminium conductor has magnetic loss, long-time running line loss is bigger, the degree of speeding of circuit will be increased, bring bigger potential safety hazard for the operation of electric power system, must increase the iron tower height or reduce distance between tower, especially under the situation of system's increase-volume, just must change iron tower for eliminating this hidden danger.So, not only can increase workload, increase the iron tower root and open, reduce the greenery patches, and cause serious economy loss.Therefore, in present electric network reconstruction process, change the steel reinforced aluminium conductor of part circuit into capacity-improving conducting wires, promptly high temperature resistant, low degree of speeding carbon fiber complex core aluminium stranded conductor.At present fixedly the strain clamp of steel core aluminium hinge line has the wire clamp main body that the aluminum pipe of connecting plate is formed by an end, the drainage wire clamp that is connected with the wire clamp main body and insert the partly interior steel anchor formation of wire clamp main body aluminum pipe.Earlier steel core aluminium hinge line is fixed with the crimping of steel anchor during installation, carried out crimping respectively in the both sides of crimping point again after putting the wire clamp main body.Anti-ecological deterioration performance is good although carbon fiber complex core has, non-corrosive, not burn into not with aluminum conductor or other parts advantages such as reaction that produce electrolysis, but because carbon fiber complex core is a fragile material, under the inhomogeneous situation of radial force, easily cause damage to make its fracture, thereby reduce the bearing capacity of carbon fiber core along the line direction to fiber.This shows that existing strain clamp can't adapt to the strain insulator of carbon fiber complex core aluminium stranded conductor at all to be fixed.Become this field and thirst for solving but still unsolved technical barrier.
Summary of the invention:
The utility model is for a kind of tension resisting clip for carbon fiber composite core conductive wire is provided, and mainly is that the strain insulator that solves the inapplicable carbon fiber complex core aluminium stranded conductor of existing strain clamp is fixed, and easily core is caused the problem of damage or fracture during crimping.
Scheme of the present utility model is as described below: this utility model comprises wire clamp main body, drainage wire clamp, steel anchor, connecting bolt, also comprise internal lining pipe, it be by be provided with in the online clip main body in wedge shape holder and the wedge shape holder with its in the wedge grip that matches of hole shape, and set up in the online clip main body that internal lining pipe constitutes.Wherein the wedge shape holder is established conical through-hole in being, is the cylindrical cover for seat of an end projection outward.And wedge grip is the taper type chuck of through hole in being, axially is arranged with two groups of gaps on the cone of this chuck, 90 ° of formations each other between two groups of gaps.
The beneficial effect that this reality is novel: this utility model is owing to taked to be provided with in the online clip main body structure of wedge shape holder, wedge grip and internal lining pipe; making full use of the characteristics that wedge grip can move in the wedge shape holder clamps carbon fiber complex core; and with the collinear clip main body of set internal lining pipe, the firm crimping one of aluminium stranded conductor in the crimp segment, and carbon fiber complex core there is not any damage (mainly being because the existence of internal lining pipe has been played protective effect to carbon fiber complex core).Moreover, this utility model also have compact to design reasonable, novel ingenious, temperature influence is little, shock-resistant fatigue resistance is strong, grip is evenly distributed, carries gripping force and by force, effectively avoids advantages such as grip is loose.Meanwhile, use this strain clamp, under system's increase-volume situation, needn't change iron tower, do not destroy the greenery patches, reduce economic loss, not only economy but also practicality.Have using value and vast potential for future development.
Description of drawings:
Fig. 1 is the overall structure schematic diagram of tension resisting clip for carbon fiber composite core conductive wire.
Embodiment:
The wire clamp main body 1 that its outside of tension resisting clip for carbon fiber composite core conductive wire shown in Figure 1 is made up of the connecting plate of aluminum pipe and aluminum pipe one end, corresponding crimp segment is established internal lining pipe 2 in the online clip main body 1, a wedge shape holder 3 also is set in the online clip main body 1, and the wedge grip 4 that matches with its interior hole shape in the wedge shape holder 3.Described wedge shape holder 3 is established conical through-hole in being, is the cylindrical cover for seat of an end projection outward.And wedge grip 4 is the taper type chuck of through hole in being, axially is being arranged with between 8, two groups of gaps 8, two groups of gaps 90 ° each other on the cone of this chuck.Steel anchor 5 from wire clamp main body 1 one ends screw in through screw thread and wire clamp main body 1 aluminum pipe partly and wedge shape holder 3 be connected and fixed.And online clip main body 1 connecting plate place through bolt 6 fixedly drainage wire clamp 7 constitute.During installation, with the exposed part of carbon fiber complex core aluminium stranded conductor termination core, till the end that the carbon fiber complex core aluminium stranded conductor is provided with internal lining pipe 2 from strain clamp inserts wire clamp and clamps to the wedge grip 4 then.At last carrying out crimping in wire clamp main body 1 outside of establishing internal lining pipe 2 and steel anchor 5 with hydraulic method gets final product.In use steel anchor 5, wedge shape holder 3, wedge grip 4 and carbon fiber complex core connect one, along with expanding with heat and contract with cold of variations in temperature metal material, wedge grip 4 can move along wedge shape holder 3 inner conical through holes under the wire tension effect, and under the effect of wedge grip 4 gaps 8, carbon fiber complex core is held tighter, thereby guarantee that enough grips play good strain insulator effect to lead.
