Description
Technical field
The immobilising device in a kind of transmission line of electricity is the utility model is related to, especially a kind of overhead transmission line is protected with carrying out safety backup
Protection unit.
Background technology
When setting up wire, wire needs to use hydraulic strain clamp with corner pole, strain rod tower, terminal shaft tower,
And conventional hydraulic type strain clamp is because overhead transmission line own tension is larger, again for a long time by aeolian vibration or the shadow of icing
Ring, it is easy to tired stranded or even fracture accident occurs in hydraulic strain clamp exit；Spiral shell at strain clamp drainage plate
Bolt, which produces, loosens (this phenomenon can not avoid), and then produces larger contact resistance, electric current by when, can be generated heat in drainage plate
It is more serious, more than the code requirement of line security operation, the generation of drainage version fracture accident occurs at any time.
The presence of above-mentioned phenomenon, no small hidden danger is brought for the safe operation of circuit, can influence overhead transmission line uses the longevity
Life, causes power outage.Below overhead transmission line if high-speed railway, highway and critical facility (low-voltage power line,
Gas station, gas station), gone offline once rupture of line occurs, great secondary disaster certainly will be caused.
Utility model content
In order to eliminate possible hidden danger, it is necessary to develop a kind of carrying out safety backup wire clamp, it is ensured that still can when accident occurs
Wire (meeting normal work tension force) is tensed, conducting electric current, is reduced due to being lost caused by power outage, when being won to repairing
Between.The utility model proposes a kind of overhead transmission line carrying out safety backup protection device.
The utility model adopts the following technical scheme that：
A kind of overhead transmission line carrying out safety backup protection device, including U-shaped link, thimble, pre-hinged strain clamp, compression
Type strain clamp, drainage thread；Described thimble one end connects the lower end of U-shaped link, and the thimble other end connects preformed strain insulator
The middle twisting part of wire clamp, the both ends spire of the pre-hinged strain clamp is wrapped on aerial condutor, and winding position is remote
From the outlet of compression type strain clamp；The inner side of compression type strain clamp one end connection drainage thread, compression type strain clamp
Exit connection aerial condutor inner side.
The upper end of the U-shaped link is connected by hanging plate with the gold utensil of steel tower side.
One end of the compression type strain clamp connection drainage thread connects hanging plate by link.
Overhead transmission line carrying out safety backup protection device also includes preformed shunt bar, preformed shunt bar be middle part it is twisted,
The preformed preformed armor rods in both ends, its one end are wrapped in the outside of the aerial condutor, and the other end is wrapped in the outside of drainage thread.
Further, the preformed shunt bar is aluminium alloy shunt bar.
Further, the drainage thread, aerial condutor are steel-cored aluminium strand.
Use the advantageous effects that as above technical scheme obtains for：
For overhead transmission line carrying out safety backup protection device when accident does not occur, it is resistance to that carrying out safety backup wire clamp can share hydraulic
Born wire tension and electric current are pressed from both sides in bracing cable, reduce the probability that accident occurs, and reduce due to loss caused by power outage, give
Repairing gains time.When accident occurs, safety backup protection device tenses overhead transmission line, prevents the generation of secondary accident.
Overhead transmission line is simple in construction with carrying out safety backup protection device, easy to assembly, without construction tool, can be widely applied to
The laying of the overhead transmission line of various voltage class.
Brief description of the drawings
Fig. 1 is overhead transmission line carrying out safety backup protection device structural representation.
Fig. 2 is overhead transmission line carrying out safety backup protection device connection diagram.
In figure, 1, U-shaped link, 2, thimble, 3, pre-hinged strain clamp, 4, preformed shunt bar, 5, aerial condutor, 6,
Drainage thread, 7, compression type strain clamp.
Embodiment
It is described further with reference to 1 to 2 pair of specific embodiment of the present utility model of accompanying drawing：
Overhead transmission line includes U-shaped link 1, thimble 2, pre-hinged strain clamp 3, compression-type with carrying out safety backup protection device
Strain clamp 7, drainage thread 6, preformed shunt bar 4.The upper end of U-shaped link 1 is connected by hanging plate with the gold utensil of steel tower side, under it
End is connected with the upper end of the first thimble 2, and the centre of pre-hinged strain clamp 3 is twisted partly another with second thimble 2
One end connects, and the both ends spiral part of pre-hinged strain clamp 3 is exporting away from compression type strain clamp 7 and is being wrapped in frame
The outside of hollow wire 5.One end that compression type strain clamp 7 connects drainage thread 6 connects hanging plate by link.
Preformed shunt bar 4 is the preformed armor rods that middle part is twisted, both ends are preformed, and its one end is wrapped in the aerial condutor
5 outside, the other end are wrapped in the outside of drainage thread 6.
Before not installing preformed shunt bar additional, aerial condutor is the drainage thread and opposite side by a side compression strain clamp
Compress strain clamp connection conducting electric current；After compression type strain clamp exports wire fracture or drainage plate fracture, wire
Just lose the effect of conducting electric current, and fracture goes offline certainly will cause great secondary disaster.
After preformed shunt bar installs additional, drainage thread, shunt bar simultaneous transmission electric current, drainage thread is shared because of bolt looseness, is made
Into contact resistance it is excessive cause fever phenomenon, reduce accident；After wire fracture, preformed shunt bar conducting electric current performance
Not less than drainage thread in itself, realizing still can conducting electric current after breakdown of conducting wires.
Overhead transmission line carrying out safety backup protection device can still tense wire when accident occurs, and conducting electric current, subtract
It is small due to caused by power outage loss, gained time to repairing；When accident does not occur, carrying out safety backup wire clamp can share liquid
The wire tension and electric current that pressure strain clamp is born, reduce the probability that accident occurs.
Simultaneously when accident occurs, safety backup protection device tenses overhead transmission line, prevents rupture of line from going offline so
The generation of secondary accident.
Main traverse line and the drainage thread of compression type strain clamp connection be same model specification wire, in carrying out safety backup wire clamp in advance
Strand formula strain clamp, preformed shunt bar carry out preformed shaping according to wire type in transmission line of electricity and produced.
U-shaped link, the model of thimble are matched according to the pull-off force of wire.Overhead transmission line is protected with carrying out safety backup and filled
Put the aerial condutor for being configured in each voltage class.
In description of the present utility model, it is to be understood that term " inner side ", " outside ", " upper end ", " lower end ", " one
The orientation or position relationship of the instruction such as side ", " opposite side " are based on orientation shown in the drawings or position relationship, are for only for ease of
Describe the utility model and simplify to describe, rather than instruction or imply signified device or element must have specific orientation,
With specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
Certainly, described above is only preferred embodiment of the present utility model, and the utility model is not limited to enumerate above-mentioned
Embodiment, it should be noted that for any those skilled in the art under the guidance of this specification, that is made is all etc.
With replacement, obvious variant, all fall within the essential scope of this specification, ought to be by protection of the present utility model.
