Description
Technical field
The present invention relates to a kind of bolt type adjusting elbow, be specifically related to a kind of overhead transmission line bolt type rigid jumper regulation curved
Head, belongs to overhead transmission line gold utensil technical field.
Background technology
Since reform and opening-up, China's power industry is fast-developing, the most in recent years, along with growing continuously and fast of need for electricity,
Electric power development speed further speeds up.Power industry is the basic industry involved the interests of the state and the people.Optimize energy resources configuration, ensure
National energy security, provides high-quality, reliable supply of electric power for national economy and social development, is that structure is served in power industry
The important mission of harmonious socialist society.
Wire jumper is the important component part of transmission line of electricity, and its effect is the wire connecting anchor support both sides.When electric pressure is relatively low,
The wire of adjacent strain section generally individually uses flexible circuit conductor to connect；Along with the rising of electric pressure, wire jumper sag also with increase, for
Meet the electric clearance to tower body after wire jumper windage yaw, need to lengthen the cross-arm length of steel tower.Thus reduce wire jumper sag and windage yaw thereof
Deviant is to reduce the effective ways of anchor support size, and wire jumper sag and skew depend mainly on the wire jumper of employing or fixing wire jumper
Mode.In order to reduce tower head size as much as possible, saving steel, reduce cost, former 500kV circuit commonly uses flexible jumper the most not
Extra high voltage line wire jumper demand can be met.
The wire jumper that extra high voltage direct current transmission line engineering uses is generally rigid jumper structure, and steel tower ground connection is kept by wire jumper each several part
Reasonably distance, thus reduce the sag of wire jumper, simultaneously as the rigidity of wire jumper, under wind-force effect, its rocking tendency can
Greatly reducing, therefore can shorten the length of cross-arm. external test by reality demonstrates this result, domestic 750kV super-high voltage
Installation in road and use, also demonstrate that effectiveness and the practicality of rigid jumper.Rigid jumper is that line construction is the most complicated
Part, its corona is more serious than general line hardware.The local of the Northwest's 750kV transmission line of electricity and other engineering also using
Multiple rigid jumper form, although using method not to the utmost as, but all there is common problem, it is simply that rigid jumper and drain
The flex point that the junction of line occurs shapes bad, and at flex point, corona problem is difficult to solve.Aluminum pipe type rigid jumper wire is special due to its structure
Point, the corona problem of aluminum pipe end is more serious than other form wire jumpers.Make on 500kV and above transmission line of electricity now
Rigid jumper be divided into two kinds, aluminum pipe type rigid jumper wire and cage rigid jumper.Aluminum pipe wire jumper is mainly with 2 horizontal row
The aluminum pipe of row replaces the wire wire jumper of conventional design, and 2 horizontally arranged aluminum pipe conductor spacers are separated by.Two ends with four become wire clamps,
Drainage thread, connection gold utensil etc. are connected with wire.Aluminum pipe type rigid jumper wire is gathered around and is had the advantage that the processing of aluminum pipe wire jumper is simple, constructs
Convenient, aluminum tube sections only need to be able to be installed after aluminum pipe and conductor spacer with termination wire jumper even in factory process pre-assembled during in-site installation
Connect, accelerate the installation rate of wire jumper, alleviate workman's work high above the ground labor intensity；By one section of short strand between wire and aluminum pipe
Line is electrically connected, and is adaptable to the length of various strain insulator-string and the change of circuit corner；A whole set of wire jumper shape is completely fixed, and becomes
Shape is effective, has beautified environment；After aluminum pipe wire jumper counterweight, increase the weight of the weight of wire jumper, add the vertical component of system of jumping line,
Overall structure good stability；Inside corner, wire jumper gravity hangs, so by double string jumper strings by suspention pull bar, outside and middle phase gravity
The alternate stress that drainage thread root produces can be reduced, reduce fatigue of wriggling.Owing to aluminium tube type wire jumper has good practicality and economy
Property, UHV transmission line engineering obtains use widely.
When using rigid jumper, wire jumper, in addition to including wire and conductor spacer, also includes aluminum tube supporting structure.Execute at circuit
Man-hour, owing to being affected relative to position etc. with circuit sub-conductor, after installation in wire jumper by the structural shape of anchor support, conductor rigidity
Sub-conductor molding often neat not as circuit, and " dog leg " phenomenon easily occurs.This does not only result in wire jumper sub-conductor surface
Field intensity is powerful compared with circuit sub-conductor surface field, makes wire jumper easily produce corona, and needs to adjust sub-conductor position, reduces and execute
Work efficiency rate, causes the waste of wire and gold utensil.
