Description
Technical field
The present invention relates to a kind of preformed overhead transmission line aluminum-cladding stranded wire ground wire thunder-lightning shielding device, belong to transmission of electricity
Circuit arrester device field.
Background technology
It is a kind of more conventional lightning protection dress that lightning rod for lightning shielding failure is installed on overhead transmission line aluminum-cladding stranded wire (OPGW)
Put, its purpose is to increase the protection domain of ground wire, but aluminum-cladding stranded wire (OPGW) lightning rod for lightning shielding failure used at this stage
The modes such as be connected by screw bolts are directly anchored on ground wire more, and this structure has following drawback：
(1) sliding race easily occurs, comes off：Aerial earth wire is chronically at high-altitude wild environment, due to by the extraneous ring such as wind
Border influences, and is constantly in the state slightly shaken, and in this state, the fixed structure of connection ground wire lightning rod for lightning shielding failure easily occurs
Loosen, come off, it is therefore possible to crisis line security.
(2) easy damaged ground wire：Because bolted lightning rod for lightning shielding failure and wire can not turn into effectively overall, in extraneous ring
Under the influence of the active force of border, secure component is constantly collided with ground wire, sheared, and the abrasion of ground wire zinc coat is easily caused, so as to cause ground wire
Stranded, broken lot.
(3) pin angle in side easily changes：Because bolted lightning rod for lightning shielding failure is not maked somebody a mere figurehead for one-shot forming in itself,
Part is more and is bolt connection, and in natural environment, the angle of side pin can constantly change with the loosening of bolt, or even can go out
The phenomenon that existing side pin comes off, cause lightning protection effect and unstable.
(4) quality is larger, malleable aerial earth wire mechanical performance and sag characteristic, and installation is complex.
The content of the invention
It is an object of the invention to propose a kind of preformed overhead transmission line aluminum-cladding stranded wire ground wire thunder-lightning shielding dress
Put, the present apparatus uses preformed structure design, simple and reliable, is easy to carry, is easily installed, and cost is low, versatile, applicable wide
It is general.
Preformed overhead transmission line aluminum-cladding stranded wire ground wire thunder-lightning shielding device of the present invention, including it is preformed
Lightning rod for lightning shielding failure line, preformed lightning rod for lightning shielding failure line include lightning rod for lightning shielding failure part and preformed armor rods fixed part, lightning rod for lightning shielding failure
Part is located at the end of preformed armor rods fixed part, and the tip of lightning rod for lightning shielding failure part is provided with thunder carrying-off device.
The preformed armor rods fixed part of preformed lightning rod for lightning shielding failure line is around overlaying on aluminum-cladding stranded wire (OPGW) ground wire surface, around covering
After the completion of, preformed armor rods fixed part, which interfixes, to be prevented from sliding, and device and aluminum-cladding stranded wire is turned into an entirety, and is prevented
Shielding side pin part forms lightning protection face in aluminum-cladding stranded wire cross section, can effectively increase aerial aluminum-cladding stranded wire ground wire
In protection domain, the probability of thunderbolt wire is reduced.The shape of the thunder carrying-off device of lightning rod for lightning shielding failure portion tip can basis
It is actually needed replacing.The preformed radius size of preformed armor rods fixed part is according to overhead transmission line aluminum-cladding stranded wire (OPGW) model
It is designed processing.
Preferably, the one or both ends of described preformed armor rods fixed part are equipped with lightning rod for lightning shielding failure part, and preformed
Silk fixed part is integrally formed with lightning rod for lightning shielding failure part.Worked more after preformed armor rods fixed part and the installation of lightning rod for lightning shielding failure part
Add stabilization, it is not necessary to the cumbersome connection of bolt etc., not only alleviate quality, and be not in be come off because fixed position loosens
Phenomenon.
Preferably, the quantity of described preformed lightning rod for lightning shielding failure line is 1-10, and a plurality of preformed lightning rod for lightning shielding failure line can
Preferably to form lightning protection face, and preformed armor rods fixed part can interact and prevent from sliding.
Preferably, the length of described lightning rod for lightning shielding failure part is 0.4m-2.5m, can be actually needed change according to lightning protection
Length.
Preferably, described preformed armor rods fixed part uses the anti-skidding processing of quartz sand, prevents lightning rod for lightning shielding failure part from occurring
It is sliding to run.
Preferably, the material of described lightning rod for lightning shielding failure part is high-strength aluminum alloy.
The possessed compared with prior art beneficial effect of the present invention is：
(1) sliding race will not occur, come off：Due to the prestressed feature of preformed armor rods fixed part, preformed armor rods part and ground
Line is combined closely, and effectively prevents preformed lightning rod for lightning shielding failure line from falling off phenomenon.Simultaneously because the effect of internal layer quartz sand, in advance
Sliding race phenomenon will not also occur for strand formula lightning rod for lightning shielding failure line.
(2) aluminum-cladding stranded wire ground wire is effectively protected：Due to being twisted after preformed lightning rod for lightning shielding failure line installation with aluminium Baogang
Line ground wire is combined closely as an entirety, and each several part transitions smooth, effectively prevent a stress problem, in external environment not
Aluminum-cladding stranded wire zinc coat can be damaged, so as to effectively protect aluminum-cladding stranded wire ground wire.
(3) lightning protection stability is strong：It is more after the completion of covering because preformed lightning rod for lightning shielding failure line is disposable machine-shaping
The preformed lightning rod for lightning shielding failure line interaction of root, stability is strong, and will not be affected by the external environment change protection angle, and lightning protection is stable
Property is strong.
(4) light weight, smaller to aluminum-cladding stranded wire (OPGW) mechanical performance and sag characteristic change, installation is simple.
