Description
Technical field
The utility model is related to ultra-high-tension power transmission line gold utensil arcing horn, the adjustable transmission of electricity of more particularly to a kind of size and gap
Circuit arcing horn.
Background technology
Arcing horn is used in high pressure overhead power line, plays a part of anti-lightning strike protection to insulator.
The antifouling always work about electric power person of Lightning Protection on Power Transmission Lines makes great efforts the problem of research.Lightning stroke flashover or pollution flashover
After can damage insulator, bring difficulty to circuit operation maintenance.Arcing horn can play a part of protecting insulator, its core concept
It is in parallel with insulator chain using arcing horn, thunder energy dredges electric arc by the release of arcing horn gap discharge, so as to play protection
The effect of insulator.
At insulator chain two ends, a pair of metal electrodes (arcing horn) in parallel constitutes gap, generally recruits arc gap to be less than insulator
Overall length.When overhead transmission line be struck by lightning, very high lightning surge is produced on insulator chain, but because the thunder and lightning of portable protective gaps is rushed
The discharge voltage that discharge voltage is less than insulator chain is hit, therefore portable protective gaps discharge first.The electric arc continued should in electric power and heat
Under power effect, the discharge channel formed by parallel connection gaps is directed to arcing horn end, is fixed on arcing horn cigarette burning,
So as to protect insulator from electric arc calcination.Usual parallel connection gaps can make the tripping rate with lightning strike of circuit increase, but between parallel connection
Gap can protect insulator without damage after arc extinction, so as to reduce line accident rate, and also should be can be with circuit operation
Receive.Arcing horn gap typically takes in string between insulator total length 75% -90% (flashover strike) and is not less than 75%
As shown in figure 1, existing arcing horn is a pair of metal electrodes rod, metal electrode bar have it is straight to section, oblique section and
Changeover portion between the two, because metal electrode is integral, the size of arcing horn and gap are nonadjustable, and due to life
Produce mismachining tolerance, alignment error, overhead transmission line, such as thunderbolt feelings of later stage operation phase each route segment longer by path
Condition changes and needs adjustment arcing horn gap, and run unit is difficult to make gap adjustment according to actual conditions.
Utility model content
Technical problem to be solved in the utility model is to provide the adjustable transmission line of electricity arcing horn of a kind of size and gap,
Its size and gap can be adjusted flexibly, and effectively improve the convenience installed and safeguarded.
It is as follows that the utility model solves the technical scheme that its technical problem used：
The adjustable transmission line of electricity arcing horn of a kind of size of the present utility model and gap, including with directly to section, changeover portion
With oblique section of metal electrode bar, it is characterized in that：It is described it is straight to section, changeover portion and oblique section be independent barred body component, directly to
Section has external thread section with changeover portion, changeover portion and oblique section of abutting end, directly to section and changeover portion, changeover portion and oblique section point
It is not threadedly coupled by internally threaded sleeve formation, fastening bolt is provided with internally threaded sleeve.
The beneficial effects of the utility model are, directly to section, oblique section it is scalable, can meet will to various insulator disk footpaths
Ask；Construction, operation maintenance unit can do gap adjustment according to actual conditions；The mould that production link can be reduced is used, reduction life
Produce cost；Different voltages can be met using scalable adjustment function to use, and eliminate design iterations；Install and safeguard simple easily behaviour
Make, construction costs is had no significant effect.
Brief description of the drawings
This specification includes following four width accompanying drawing：
Fig. 1 is schematic diagram in the structure and installation and suspension string, jumper string of existing arcing horn；
Fig. 2 is the front view of the adjustable transmission line of electricity arcing horn of a kind of size of the utility model and gap；
Fig. 3 is the top view of the adjustable transmission line of electricity arcing horn of a kind of size of the utility model and gap；
Fig. 4 is the profile of the line A-A along along Fig. 2.
Component and corresponding mark are shown in figure：Directly to section 11, changeover portion 12, oblique section 13, internally threaded sleeve 20, fastening
Bolt 21.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Reference picture 2 and Fig. 3, the adjustable transmission line of electricity arcing horn of a kind of size of the present utility model and gap, including with
Directly to section 11, changeover portion 12 and oblique section 13 of metal electrode bar.Described is directly independent to section 11, changeover portion 12 and oblique section 13
Barred body component, directly there is external thread section to section 11 and changeover portion 12, changeover portion 12 and oblique section 13 of abutting end, directly to section 11
It is threadedly coupled respectively by the formation of internally threaded sleeve 20 with oblique section 13 with changeover portion 12, changeover portion 12, in internally threaded sleeve 20
It is provided with fastening bolt 21.Changeover portion 12 can be relative to directly stretching to section 11, so as to adjust the size of arcing horn, oblique section 13 can
It is flexible relative to changeover portion 12, so as to adjust the gap between a pair of arcing horns.
Reference picture 3 and Fig. 4, it is described directly to be opened up to longitudinally spaced on section 11, changeover portion 12 and oblique section of 13 external thread sections
There is through hole, the end of internally threaded sleeve 20 offers positioning hole, and each through hole, positioning hole are in the same plane, fastening bolt 21
Bar portion pass through positioning hole and corresponding through hole, to ensure to be in same level after installing, the operation phase do not loosen.
A kind of size of the utility model and gap adjustable transmission line of electricity arcing horn described above that simply explains through diagrams
Some principles, are not intended to the utility model being confined in shown and described concrete structure and the scope of application, therefore every institute
Corresponding modification and the modification of adjustment fixed form and the equivalent being utilized are possible to, the utility model is belonged to apllied specially
Sharp scope.
