Description
Technical field
A kind of high pressure baffle assembly is the utility model is related to, for (the following letter of SF6 Cubicle Gas-Insulated Switchgears
Referred to as GIS) in, belong to electrical equipment technical field.
Background technology
High pressure dividing plate is a critical component of GIS device, for the mechanical support and electricity between GIS live parts and ground
Draw last breath edge, be additionally operable to separate each adjacent gas compartments of GIS, this requires high pressure dividing plate hydraulic pressure demolition value to need setting more than 3 times
The problem of counting pressure, and not allowing to leak air between conductor and epoxy resin interface occurs.
At present, existing Cubicle Gas-Insulated Switchgear (GIS) uses high pressure dividing plate, typically using conductor, flange
Structure by poured with epoxy resin together simultaneously, is influenceed, it is in curing molding by the intrinsic operational characteristic of vacuum epoxy casting
During, because the difference of metallic conductor and epoxy expansion coefficient and constriction coefficient, and epoxy resin will pass through heat absorption, put
The thermally and chemically relative complex process such as reaction, so inevitably producing what is be harmful between metallic conductor and epoxy resin interface
The problem of residual stress and bad bonding interface, this is too low by the hydraulic pressure demolition value for causing high pressure dividing plate, and hydraulic pressure demolition value is disperseed
Property is excessive, and easily leak air phenomenon between conductor and epoxy resin interface, product yield it is too low.
The content of the invention
The technical problems to be solved in the utility model is：Provide a kind of assembling amount less, technique is simple, manufacture is convenient, raw
The high high pressure baffle assembly of efficiency high, yields is produced, solves the dispersed excessive and conductor of high pressure dividing plate hydraulic pressure demolition value and ring
The technical problem easily to be leaked air between oxygen resin boundary surface.
In order to solve the above-mentioned technical problem, the technical solution of the utility model there is provided a kind of high pressure baffle assembly, bag
Lower end conductor is included, the upper end of lower end conductor is connected through high pressure dividing plate with upper end conductor, it is characterised in that described high pressure dividing plate
Epoxyresin insulator including curing molding, epoxyresin insulator outside are surrounded with metal flange, epoxyresin insulator
In conical structure, and the center at the top of epoxyresin insulator is provided with a circular hole, and the top of circular hole is provided with a step.
Preferably, described metal flange is circular ring.
Preferably, described metal flange is the flange that the good aluminium of electric conductivity is made.
Preferably, the upper center of described lower end conductor has a rectangular seal groove, and the lower end of lower end conductor is touched to be conventional
Headstock structure.
Preferably, described lower end conductor is aluminum casting conductor.
Preferably, being provided between described lower end conductor and epoxyresin insulator prevents the sealing ring of gas leakage.
Preferably, described sealing ring is the o type sealing rings of ethylene-propylene diene copolymer material.
The utility model eliminates the metallic conductor in conventional high-tension dividing plate, uses the taper different from conventional bowl shaped structure
Dividing plate, thus its assembling amount less, technique is simple, manufacture is convenient, production efficiency is high, yields is high.Meanwhile take the center conductor later stage
The mode of assembling, fundamentally avoid and harmful residual stress is produced between metallic conductor and epoxy resin interface and interface occurs
The problem of poor attachment, the solution of these problems directly enhance the hydraulic pressure demolition value of high pressure dividing plate, solve hydraulic pressure demolition value point
Property excessive the problem of easily being leaked air between metallic conductor and epoxy resin interface is dissipated, and then improves the yields of product, is reduced
The cost of product.
Brief description of the drawings
Fig. 1 is a kind of sectional view of high pressure dividing plate；
Fig. 2 is a kind of sectional view of high pressure baffle assembly；
Fig. 3 is the sectional view of lower end conductor.
Embodiment
To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The utility model is a kind of high pressure baffle assembly, as shown in Fig. 2 it includes upper end conductor 10, sealing ring 20, high pressure
Dividing plate 30, lower end conductor 40.A kind of high pressure baffle assembly of the present utility model is numerous dresses during high pressure dividing plate 30 actually uses
One kind in matching somebody with somebody, in practical set, first sealing ring 20 is placed in the seal groove of lower end conductor 40, afterwards worn lower end conductor 40
High pressure dividing plate 30 is crossed, being fastened by bolts handle with upper end conductor 10 connects.Metal flange 32 is ground potential, upper end conductor 10 and lower end
Conductor 40 is high potential.
Sealing ring 20 is the o type sealing rings of ethylene-propylene diene copolymer material, is placed on lower end conductor 40 and epoxyresin insulator
Between 31 interfaces, sealing function is primarily served, prevents gas leakage.
As shown in figure 3, lower end conductor 40 is aluminum casting conductor, its upper center has a rectangular seal groove, and lower end is normal
Contact holder structure is advised, the structure reduces a contact surface and a step linkage editor is connect than conventional structure, can improve efficiency of assembling,
Contact resistance is reduced, improves through-current capability.
As shown in figure 1, the epoxyresin insulator 31 of high pressure dividing plate 30 including curing molding, around epoxy resins insulation
The metal flange 32 in the outside of body 31.
Epoxyresin insulator 31 is in conical structure, and is provided with a circle at the center at the top of epoxyresin insulator 31
Hole, the top of circular hole are provided with a step.Because the metallic conductor in conventional high-tension dividing plate is cancelled, and still it is different from conventional bowl-type
The conical baffle of structure, thus its assembling amount less, technique is simple, manufacture is convenient, production efficiency is high, yields is high.Meanwhile because of center
Conductor takes the mode assembled in the later stage, should so fundamentally avoiding harmful residual between metallic conductor and epoxy resin interface
The generation of the problems such as power and bad bonding interface, the solution of these problems directly enhance the hydraulic pressure demolition value of dividing plate, solve water
Explosion value dispersiveness excessive the problem of easily being leaked air between metallic conductor and epoxy resin interface is pressed, and then improves the good of product
Product rate, reduce the cost of product.
Metal flange 32 is circular ring, is centered around the outside of epoxyresin insulator 31, and material is that electric conductivity is good
Aluminium, be connected between shell so as to realizing it with basin and be effectively electrically connected.
