Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
It is a kind of sectional view of bus supporting insulator provided by the embodiment of the utility model referring to Fig. 1.
A kind of bus supporting insulator provided in this embodiment, be suitable for GIS perhaps GIL equipment including the GIS or
The shell 1 of GIL equipment, the bus 2 of the GIS GIL equipment and bus supporting insulator ontology 3；The bus support is exhausted
Edge ontology 3 includes that full skirt 34 is climbed in epoxy resin impregnated paper 31, screening electrodes 32, electrode protecting layer 33 and increasing；The bus support
Insulator body 3 is equipped with epoxy resin impregnated paper 31 described in several layers；It is pressed between any two layers of epoxy resin impregnated paper 31 equipped with described
Electrode 32；The epoxy resin impregnated paper 31 is with the screening electrodes 32 on the bus 2 of the GIS GIL equipment；Institute
It states epoxy resin impregnated paper 31 and is coated with the screening electrodes 32 by the electrode protecting layer 33；The lateral surface of the electrode protecting layer
Full skirt 34 is climbed in the increasing for being equipped with several layers annular.
Further, the bus supporting insulator ontology 3 is in contact with the shell 1 of the GIS GIL equipment；Institute
The bus 2 of GIS GIL equipment is stated through the bus supporting insulator ontology 3.
Further, the bus supporting insulator ontology 3 is spindle structure.
Preferably, the screening electrodes 32 be aluminium foil, the electrode protecting layer 33, increasing climb full skirt 34 be pure epoxy resin or
Person's epoxy resin impregnated paper；It is insulation gas filled between the bus 2 and the shell 1；Wherein, SF is used in the present embodiment6Gas,
The dielectric strength of insulator can be effectively improved.
Wherein, the screening electrodes number of plies of bus supporting insulator, thickness, every layer of axial length, end length of bench, with
And the thickness of the electrode protecting layer made of pure epoxy resin or epoxy resin impregnated paper, shape, position need to pass through insulating Design
It checks to determine.In general, the core design parameter for the bus supporting insulator that electrode is pressed can pass through finite element stimulation
Software (such as Maxwell) carries out potential and electric field distributions calculating, carries out design optimization for calculated result and determined later.
It should be noted that the process flow of the bus supporting insulator of the present embodiment is to be required first to exist according to design drawing
The crimped paper that the corresponding number of plies, length and thickness are wound on the bus mold of up- coiler often rolls one layer of completion according to design size
It is required that increasing by one layer of aluminium foil screening electrodes, epoxy impregnation furnace is entered after the completion of all rolling, is dried, vacuumize process
Afterwards, start epoxy vacuum impregnation, hot setting is carried out after the completion of to be impregnated, according to layout design by shape turning after the completion of solidification
Full skirt is climbed in the increasing circularized, the final molding after polishing；Wherein, polishing step can effectively improve the apparent matter of bus supporting insulator
Amount.
Wherein, which, which climbs full skirt 34, can be the equal single umbrella of diameter, be also possible to anisodiametric gamp and umbellule
Combination.
In an alternative embodiment, and all long beyond screening electrodes if each layer crimped paper equal length when winding
Degree, winding are after the completion the coaxial clyinders for being not impregnated with epoxy, then the electrode protecting layer 33 of the bus supporting insulator is climbed with increasing
Full skirt 34 is the epoxy resin impregnated paper not contacted with screening electrodes.
In an alternative embodiment, if when winding each layer wrinkle paper length and respective layer aluminium foil equal length,
It is the coaxial cone for being not impregnated with epoxy after the completion of winding, then full skirt is climbed in the electrode protecting layer 33 of the bus supporting insulator and increasing
34 be pure epoxy resin.
It referring to fig. 2, is a kind of dry arcing distance schematic diagram of bus supporting insulator provided by the embodiment of the utility model, it is right
In the situation inadequate along face dry arcing distance, it will be turned on the outside of the electrode protecting layer 33 of bus-bar insulator ontology 3 and climb umbrella with increasing
The shape of skirt 34 increases dry arcing distance.At this point, dry arcing distance is electrode protecting layer 33 and full skirt 34 is climbed in increasing and insulating gas is handed over
The total length of the contour line at interface, the dry arcing distance equivalent to increase the sum of all full skirt outer contour length.
The utility model embodiment is set as increasing and climb by 33 lateral surface of electrode protecting layer in bus-bar insulator ontology 3
The shape of full skirt 34 increases dry arcing distance, increases the dry arcing distance of the sum of all full skirt outer contour length, so as to have
Effect increase insulator along face dry arcing distance, to avoid the edge flashing of insulator.Secondly, passing through several layers epoxy resin impregnated paper
The structure of screening electrodes 32 is equipped between 31 and every layer of epoxy resin impregnated paper 31, so that every layer of epoxy resin impregnated paper 31 is inside and outside
Surface is respectively formed equipotential plane, solves and occurs the phenomenon that interfacial effect under higher working voltage, and is easier to initiation office
The problem of portion discharges, can effectively slow down interfacial effect.And epoxy resin impregnated paper 31 and screening electrodes 32 form multilayer platform on the whole
Rank is constituted trapezoidal, and bus supporting insulator is uniform along face current potential and local field distribution, and local field strength centrostigma, energy is not present

Electrode protecting layer 33 is set, causes electric discharge in gas to avoid the naked leakage of screening electrodes 32, reduces the probability of happening of shelf depreciation.
Using the insulator process flow being different from the prior art, it is not easy to the phenomenon that stress raisers occur, can be effectively reduced interior
A possibility that stress concentration in portion's causes insulator to burst.It is again, since the prior art is installing fixed normal needs installation specially
Busbar joint, be easy to produce die misalignment and busbar joint caused to overheat, by using bus run through bus supporting insulator
The structure type of ontology, it is not necessary to busbar joint is designed, thus the risk for avoiding connector from overheating.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the protection scope of the utility model.
