Abstract
A kind of lightning protection optical fiber composite insulator, including plug, plug is built-in with optical fiber, and plug is externally provided with sheath, and full skirt, metal anchor ear are set with outside sheath, plug upper end crimps upper end gold utensil, plug lower end crimps lower end gold utensil, and metal anchor ear is cased with low-pressure end grading ring near upper end gold utensil outside metal anchor ear, discharge counter is connected with through wire on low-pressure end grading ring, high-pressure side grading ring is cased with outside the gold utensil of lower end.The present invention increases by a metal anchor ear and is used to install grading ring and connects discharge counter in composite insulator low-pressure end, tail end reserves certain insulation distance, for discharge counter work, being allowed to meet lightning monitoring product can effectively solve to thunder and lightning detection demand, reliability of the present invention is good, technical risk is small, and versatility is excellent.
Description
Technical field
The present invention relates to insulator used in power system and electric railway.
Background technology
In power system, generator, transformer, insulator are main three-major-items.Insulator is through each link in power transmission and transformation, insulator can be divided into glass, ceramics and composite insulator by insulator material, insulator is coupled with gold utensil by modes such as glue connection, filling or crimping, but thunder and lightning weather is not fee under the natural endowment of the Nature, therefore when in thunder and lightning weather, the meeting that thunder and lightning is not fee from is impacted onto insulator, and insulator can be damaged because of thunderbolt.
The content of the invention
The invention aims to overcome the above-mentioned deficiency of prior art, and a kind of lightning protection optical fiber composite insulator is provided, can be easily installed insulator discharge counter can make without lightning stroke flashover again when normally runs, while not influenceing the work of discharge counter.
The technical scheme is that：Including plug, plug is built-in with optical fiber, plug is externally provided with sheath, full skirt, metal anchor ear, plug upper end crimping upper end gold utensil, plug lower end crimping lower end gold utensil are set with outside sheath, metal anchor ear is near upper end gold utensil, low-pressure end grading ring is cased with outside metal anchor ear, discharge counter is connected with through wire on low-pressure end grading ring, high-pressure side grading ring is cased with outside the gold utensil of lower end.
Full skirt by multiple cycles full skirt group order arrangement form, the full skirt group in each cycle includes big full skirt, small full skirt.
It is separated by 2-3 cycle full skirt group between metal anchor ear and upper end gold utensil.
Install grading ring and discharge counter on insulator additional, grading ring is connected on insulator low-pressure end（Upper end）Composite insulator is a kind of polymeric type insulator that the overcoat at least by two kinds of insulating elements i.e. plug and equipped with metal-ware is constituted, middle plug is mainly made up of glass-epoxy leading-drawing rod, by silicone rubber jacket and full skirt entirety injection pressure or extrude rear enclosure and load onto full skirt both techniques in mandrel outer and constitute outside plug, connection gold utensil is then to be crimped on plug two ends, metal anchor ear is being connected near the appropriate position of upper end gold utensil, grading ring is connected to outside metal anchor ear, by connecting a wire connection discharge counter on metal anchor ear, discharge counter is a kind of device for being subjected to lightning impulse for recording insulator, and optical fiber is added in plug for conduct data.
The present invention solves the problems, such as existing insulator due to no counting device and data conduction device so cannot count and Lightning proof, and it is mainly recorded by being improved and develop supporting discharge counter to existing composite insulator to the number of times of generation lightning stroke flashover.Thunderbolt position and number of lightning strokes are recorded by more easy mode and the multiple location of thunder and lightning is determined by statistics, analysis, then take specific aim measure to carry out lightning protection measures treatment, reduced tripping rate with lightning strike.
The invention has the advantages that：
1st, the anchor ear of an installation grading ring is set up on composite insulator, double insulation is formed, it is possible to increase the performance of insulator.
2nd, discharge counter is installed on low-pressure end grading ring, the number of times that lightning stroke flashover can occur is recorded, and by the optical fiber in plug data transfer to specified location.
3rd, thunderbolt position and number of lightning strokes are recorded by distinctive mode and the multiple location of thunder and lightning is determined by statistics, analysis, then take specific aim measure to carry out lightning protection measures treatment, reduced tripping rate with lightning strike.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
In Fig. 1, low-pressure end grading ring 4, discharge counter 5 are installed additional in the low-pressure end of composite insulator 1, install optical fiber 2 additional in plug, carry out Information Conduction, installing grading ring additional in the low-pressure end of insulator makes it become insulation insulator in pairs.Mandrel outer has sheath, full skirt is cased with outside sheath, sheath, full skirt are made of silastic materials, the two ends of plug are no sheaths, it is, in order to crimp upper end gold utensil, lower end gold utensil, to be separated by the 2-3 full skirt in cycle and then look for appropriate position to connect metal anchor ear 3 outside core bar jacket, low-pressure end grading ring is placed on metal anchor ear 3, high-pressure side grading ring 6 is enclosed within the installation of lower end gold utensil outer end, is close to lower end installation.
