Description
Technical field
The utility model is related to electrical distribution field, specially a kind of resistance to bracing cable of carbon fiber composite core wire combined type
Folder.
Background technology
Strain clamp is the gold for fixing conducting wire in electric system on overhead power line and substation's strain rod tower
Tool, conducting wire is connect by it with insulator chain, and insulator chain is connect with steel tower again, to carry the pulling force of conducting wire, reduces the relaxation of conducting wire
Degree, plays the role of the safe operation of electric system highly important.
For a long time, conducting wire is all made of steel-cored aluminium strand, since steel-cored aluminium strand has magnetic loss, longtime running line loss
It is larger, also the degree of speeding of circuit will be made to increase when temperature is higher, brought great potential safety hazard to the operation of electric system, to eliminate
The hidden danger must increase steel tower height or reduce distance between tower, especially must just replace steel tower in the case of system increase-volume.
So, it can not only increase workload, increase steel tower root and open, reduce greenery patches, and cause serious economic loss.Therefore,
The steel-cored aluminium strand of part circuit is changed to capacity-improving conducting wires, i.e. high temperature resistant, low degree of speeding carbon fiber during current electric network reconstruction
Tie up composite core aluminum stranded wire.
Currently, the wire clip body that the strain clamp of fixed steel-core-aluminium hinge line is made of aluminum pipe of the one end with connecting plate,
What the steel anchor in conduction wire clamp and merging wire clip body aluminum tube sections being connect with wire clip body was constituted.First by steel-core-aluminium when installation
It cuts with scissors line and crimps fixation with steel anchor, crimped respectively in the both sides of crimping point again after putting on wire clip body.Although carbon fiber is compound
Core has many advantages, such as that good resistance to environmental degradation performance, non-corrosive, burn into does not generate cell reaction with aluminum conductor or other components,
But due to carbon fiber complex core be fragile material, in the case that radial force it is uneven easily to fiber cause damage make its fracture,
To reduce the bearing capacity in carbon fiber core fair line direction.It can be seen that existing strain clamp can not adapt to carbon fiber at all
The strain insulator of composite core aluminum stranded wire is fixed.Thirst for solving but still unsolved technical barrier as the field.
Intersect with other voltage class engineering circuits in addition, being frequently encountered in China's extra high voltage line Process of Engineering Construction
Bridging phenomenon needs crossed line to stop transport during intersecting segment line Poling Construction, therefore, intersects segment line frame
The time length of line construction is determined by cross-line road idle time length.Currently, the lead construction time is shorter in the world
Method is assembly type overhead method, and this method is by accurately measuring and calculating, find out the length of required conducting wire, accurate measuring
Line length, and in both ends crimping and tension-resisting clip unfolds the stringing method that anchor support is directly hung up after this section.With common stringing method
It compares, to be unfolded after first pressure conducting wire, it is therefore desirable to which the strain clamp of design is allowed for through the equipment such as coaster, resistance to bracing cable
Folder drainage plate needs are placed in after completing compression joint technique again on strain clamp supervisor.
Utility model content
The purpose of this utility model is to provide a kind of carbon fiber composite core wire combined type strain clamp, can effectively solve
Certainly technical problem present in background technology.
Realizing the technical solution of above-mentioned purpose is：A kind of carbon fiber composite core wire combined type strain clamp, feature
It is：Including wire clip body, drainage plate, conduction wire clamp, steel anchor, in wire clip body corresponding to crimp segment sets internal lining pipe, in wire clamp
Also set up a wedge-shaped holder in main body and the wedge grip to match with its internal via shape in wedge-shaped holder be set, steel anchor from
Wire clip body one end is screwed in be connected and fixed through screw thread and wire clip body and wedge-shaped holder；
Wedge-shaped holder is to set conical through-hole in a, is outer as the cylindrical cover for seat of one end protrusion, and wedge grip is in a for through-hole
Taper type chuck, two groups of gaps are axially and symmetrically equipped in the cone of taper type chuck, 90 ° each other between two groups of gaps；
The drainage plate includes left circular arc body, right circular arc body of the obvolvent in wire clip body, left circular arc body, right circular arc body with
For wire clip body by being welded and fixed, the lower end of left circular arc body and right circular arc body has been wholely set clamping plate respectively, is arranged between clamping plate
There are the gap for clamping conduction wire clamp, the connecting pin of conduction wire clamp to be installed between clamping plate and be bolted.
Further, steel anchor is made of invar.
The novel advantageous effect of this reality：Wedge-shaped holder, wedge shape is arranged due to taking in the utility model in wire clip body
The structure of folder and internal lining pipe makes full use of wedge grip can be the characteristics of wedge-shaped holder inner shaft is to movement and forms radial pressure by carbon
Fiber composite core clamps, and the same wire clip body of set internal lining pipe, aluminum stranded conductor in crimp segment are securely crimped one, and to carbon fiber
Composite core is without any damage (mainly since the presence of internal lining pipe plays protective effect to carbon fiber complex core).
The utility model also have it is compact to design it is reasonable, it is novel it is ingenious, be affected by temperature small, impact resistance fatigue resistance
By force, grip is evenly distributed, carries that gripping force is strong, the advantages that effectively grip being avoided to relax.
This reality is novel circular barber-pole stripes, spiral-shaped change strain clamp position in strain clamp outer body
Aerodynamic shape, can make strain clamp along its length on wind-engaging cross section constantly change；It can also be in clammy day
It is irregular shape so that strain clamp is cladded with moon exterior feature under gas, and section is made to change along the hand of spiral, so that empty caused by wind-force
Aerodynamic effect is interfered with each other and is restricted, to destroy the condition danced:Its lift coefficient is set to reduce, lift coefficient curve becomes
Change tends to be steady, and the increase of resistance coefficient can make conducting wire consume more energy during the motion, advantageously reduce transmission of electricity
Line oscillation probability simultaneously reduces transmission line galloping amplitude.As the above scheme is adopted so that the utility model is in use,
Windage can be reduced, and reduce transmission line galloping probability and reduce transmission line galloping amplitude.
The drainage plate of the utility model uses the split structure being made of left circular arc body, right circular arc body, can be in wire clamp
After main body is by equipment such as coasters, then drainage plate obvolvent is welded in wire clip body, avoids drainage plate to equipment such as coasters
Walking cause to hinder, great application value and vast potential for future development.
The left circular arc body of the utility model and the lower end of right circular arc body have been wholely set clamping plate respectively, are provided between clamping plate
The gap of conduction wire clamp is clamped, the connecting pin of conduction wire clamp is installed between clamping plate, improves connecing for drainage plate and conduction wire clamp
Contacting surface is accumulated, and conductive effect is improved.
