Abstract
Type major diameter composite electric insulator core bar is poured the utility model discloses one kind, with outer LIFT and plug, it is characterised in that the junction between outer LIFT and plug has triangle thread or rectangular thread.Its advantage is to increased triangle or rectangular thread on the surface of plug, after pouring or die casting is successful, these thread grooves can be combined with the glass epoxide resin material for pouring well, reduce to greatest extent due to defects such as interface shrinkage, the crackles for pouring generation, improve the mechanical strength of major diameter plug.
Description
Technical field
The utility model belongs to the compound inslation subassembly in electric power facility, be specifically one kind pour type major diameter answer
Close core rod of insulator.
Background technology
With developing rapidly for electric power project of transmitting and converting electricity, the voltage class more and more higher of power Transmission, this is accomplished by more
Large-scale electric power facility is used as the base parts and components of power transmission and transformation, to ensure the stable operation of power transmission and transformation system.Relative to current
Drawing and extruding bar technological level, the composite electric insulator core bar of major diameter needs to be poured or die casting could meet needs by secondary,
But, due to plug and pour or the material of die casting between can produce interface between crackle, shrink and the defect such as bubble,
The physical property of major diameter plug, particularly tensile strength are influenceed, so as to influence its application in practice.In order to overcome this
Problem.Designer of the present utility model has done and has studied in earnest, it is proposed that goal of the invention of the present utility model.
The content of the invention
Goal of the invention of the present utility model be in order to overcome above-mentioned major diameter plug due to pour or die casting produce not
Good problem and put forward.One kind is provided and pours type major diameter composite electric insulator core bar.
Technical solution of the present utility model is achieved in that this kind pours type major diameter composite electric insulator core bar,
With outer LIFT and plug, it is characterised in that the junction between outer LIFT and plug has triangle thread or rectangle
Screw thread.
Described outer LIFT be glass fibre and epoxy resin mixing pour after formed by forcing press cure under pressure
Outer LIFT.
Junction between described outer LIFT and plug is ring channel structures connection.
Of the present utility model beneficial has the technical effect that：Triangle or rectangular thread are increased on the surface of plug, when
Pour or die casting success after, these thread grooves can be combined with the glass epoxide resin material for pouring well, to greatest extent
Reduce due to defects such as interface shrinkage, the crackles for pouring generation, improve the mechanical strength of major diameter plug.
Brief description of the drawings
Fig. 1 is the structure vertical section structure schematic diagram of the utility model plug, and Fig. 2 is the cross-sectional profile schematic diagram of Fig. 1,
Fig. 3 is the enlarged drawing of triangle thread, and Fig. 4 is the enlarged drawing of rectangular thread.Serial number in accompanying drawing：1st, outer LIFT, 2, core
Rod, 3, triangle thread, 4, rectangular thread.
Specific embodiment
The embodiment be given in below in conjunction with the accompanying drawings, to structure of the present utility model and using being described in detail.Reference
Accompanying drawing, the one kind pours type major diameter composite electric insulator core bar, with outer LIFT and plug, it is characterised in that outer LIFT
(1) junction and between plug (2) has triangle thread (3) or rectangular thread (4).
Outer LIFT (1) outside described plug (2) is that glass fibre and epoxy resin mixing pour solidify afterwards shaping
Or the outer LIFT with plug strong bonded of the stabilization formed by forcing press cure under pressure, by thread pitch with
The combination of epoxy resin is poured, the bonding strength between plug and outer LIFT is substantially increased, its machinery is not only improve only
Intensity, also improves the physical strength of whole plug.
The plug outer surface of the junction between described outer LIFT (1) and plug (2) can be that ring channel structures connect
Connect.Such structure, that is, reached goal of the invention of the present utility model.
Claims (3)
1. one kind pours type major diameter composite electric insulator core bar, with outer LIFT and plug, it is characterised in that outer LIFT and
Junction between plug has triangle thread or rectangular thread.
2. type major diameter composite electric insulator core bar is poured according to the one kind described in claim 1, it is characterised in that described outer to pour
Building layer is glass fibre and the outer LIFT that is formed by forcing press cure under pressure after epoxy resin mixing is poured.
