A large-tonnage multi-channel optical fiber composite insulator, the two ends of the mandrel are respectively crimped to two connecting fittings, the two connecting fittings have the same structure and are installed opposite to each other; The lead screw at the other end is connected with the inner cavity of the external fittings with a screw thread; one end of the connecting fittings crimped with the mandrel and the wrapping silicone rubber tape jacket is equipped with an epoxy cylinder, the outer surface of the epoxy cylinder is provided with an umbrella skirt, and the connecting fittings are provided with optical fibers The channel hole, the fiber channel hole is connected with the gap between the connecting hardware and the epoxy cylinder, and is also connected with the external hardware, and through the gap between the connecting hardware and the epoxy cylinder, the fiber channel of another connecting hardware installed oppositely is connected. The holes are connected. The invention adopts two kinds of connections of mandrel and epoxy cylinder to form double insulation and can improve the performance of the insulator. Multiple optical fibers are implanted in the gap between the mandrel and the metal fittings, which can record the number of lightning strikes and transmit the data to the designated position through the optical fiber.
Description
Technical field
The invention belongs to T & D Technology fields, are related to a kind of large-tonnage multi-channel type optical fiber composite insulator.
Background technique
In the power system, generator, transformer, insulator are main three-major-items.Insulator is through in power transmission and transformation
Each link, insulator can be divided into glass, ceramics and composite insulator by insulator material, pass through glue connection, filling or pressure
The modes such as connect to be coupled insulator with fitting, however under the natural endowment of the Nature thunder and lightning weather be it is unavoidable,
Therefore in thunder and lightning weather, in the unavoidable meeting impact to insulator of thunder and lightning, collects thunder and lightning and hit the thick related ginseng of insulator
Number becomes a new research direction.
Large-tonnage optical fiber composite insulator length is longer, and length is generally 10000mm or so, and diameter of mandrel is relatively thick,
Existing method is that optical fibre pre-buried is entered during the pultrusion of plug manufactures, and this technique may cause damage to optical fiber, be difficult
Guarantee the quality of extra-high voltage optical fiber composite insulator, and working efficiency is low.
Summary of the invention
The purpose of the invention is to overcome the above-mentioned deficiency of the prior art, and provide a kind of large-tonnage multi-channel type optical fiber
Composite insulator, insulator operates normally when can be easily installed counter but also make no lightning stroke flashover, while not influencing optical fiber
The normal work of data transmission.
The technical scheme is that plug both ends crimp two connection gold utensils respectively, two connection gold utensil structures are identical, relatively
Installation；Connection gold utensil is hollow structure, and connection gold utensil one end inner cavity is crimped with plug, the screw rod of the connection gold utensil other end and outside
The screwed connection of fitting inner cavity；Plug do not crimped with connection gold utensil position winding silicone rubber belt, connection gold utensil crimped with plug one
It is set with epoxy cylinder outside end and winding silicone rubber belt, there is full skirt in epoxy cylinder outer surface, optical-fibre channel hole, light are provided in connection gold utensil
Fine access opening is connected with the gap between connection gold utensil and epoxy cylinder, is also connected with external fitting, and through connection gold utensil and
Gap between epoxy cylinder is connected with the optical-fibre channel hole of another connection gold utensil of opposite installation.
Full skirt of the invention is formed by the full skirt group sequence arrangement in multiple periods, and the full skirt group in each period includes gamp
Skirt, small full skirt.
Plug of the present invention is mainly made of glass-epoxy leading-drawing rod.
Epoxy cylinder of the present invention is mainly made of epoxy fibreglass winding.
Before the screw rod installation of connection gold utensil of the present invention, epoxide-resin glue (sealing function) is smeared on screw rod.
Epoxy cylinder end point of the present invention is connect with external fitting, and interface is sealed with sealant.
The present invention includes the epoxy cylinder of two kinds of insulating elements i.e. plug and injection full skirt, and plug is mainly by glass fibre epoxy
Resin leading-drawing rod composition, epoxy cylinder are mainly made of epoxy fibreglass winding, and this double insulating Designs are more efficient to be ensure that absolutely
The insulation performance of edge.
The present invention solves existing insulator due to not having multifiber data conduction device so can not multiple bulk statistics
And the problem of Lightning proof, by the way that matched discharge counter is improved and developed to existing composite insulator to being struck by lightning
The number of flashover is recorded.Lightning stroke position and number of lightning strokes record and by counting, dividing by more easy mode
It analyses and determines the multiple location of thunder and lightning, specific aim measure is then taken to carry out lightning protection measures processing, reduce tripping rate with lightning strike.
Optical fibre pre-buried is entered to may cause optical fiber in the pultrusion manufacture of plug the invention avoids the prior art
Damage, ensure that the quality of extra-high voltage optical fiber composite insulator, work efficiency is high, has the advantage that
1, plug and two kinds of epoxy cylinder connections are used simultaneously, are formed double insulation, be can be improved the performance of insulator.
2, the gap between plug and fitting is implanted into multifiber, can remember to the number that lightning stroke flashover occurs
Record, and data are transferred to by optical fiber by designated position.
3, lightning stroke position and number of lightning strokes record by distinctive mode and determine that thunder and lightning is more by statistics, analysis
Location is sent out, specific aim measure is then taken to carry out lightning protection measures processing, reduces tripping rate with lightning strike.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure, 1, connection gold utensil；2, plug；3, silicone rubber belt；4, epoxy cylinder；5, external fitting；6, full skirt；7, optical fiber is logical
Road hole；8, the gap between connection gold utensil and epoxy cylinder.
Specific embodiment
In Fig. 1,1 end of connection gold utensil crimps plug 2, external fitting 5 and 1 screwed connection of connection gold utensil, in installation process
Before go on screw rod smear epoxide-resin glue (sealing function), plug 2 does not crimp position and first uses alcohol wipe, then uses silicone rubber belt
Winding, one end and winding silicone rubber belt that connection gold utensil 1 is crimped with plug 2 are set with epoxy cylinder 4,4 External infusion of epoxy cylinder outside
Silicon rubber umbrella skirt 6, full skirt 6 are formed by the full skirt group sequence arrangement in multiple periods, and the full skirt group in each period includes big full skirt, small
Full skirt.4 both ends vehicle of epoxy cylinder has outer silk, and external 5 vehicle of fitting has internal thread, and 4 end of epoxy cylinder is threadedly coupled with external fitting 5, connects
It is sealed at mouthful with sealant.1 position of connection gold utensil is provided with optical-fibre channel hole 7, and optical fiber can be by optical-fibre channel hole 7 through even
Fitting 1 and 4 gap location of epoxy cylinder are connect, by gap through the other end of insulator.
