Abstract
The utility model discloses a kind of combined type major diameter composite insulator hollow core rod, it is characterised in that hollow core rod (1) is that have the glass epoxy pultruded rod one or/and glass epoxy pultrusion type rod two or/and glass epoxy pultruded rod three of through hole and/or blind hole thereon by glass epoxy mixture material is cured or cure under pressure is combined hollow core rod by more than one layer.Its advantage is that have through hole and/or blind hole in the middle of pultruded plug as skeleton, and more closely solidification is combined as a whole from each other after each hole filling epoxy resin cure, plug internal intensity is further strengthened, so as to greatly improve tension, compression strength.
Description
Technical field
The utility model belongs to the compound inslation subassembly in electric power facility, is specifically that a kind of combined type major diameter is answered
Close insulator hollow core rod.
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,
Influence the physical property of major diameter composite insulator hollow core rod, particularly tensile strength, thus influence its in practice should
With.In order to overcome this problem.Designer of the present utility model has done and has studied in earnest, it is proposed that invention mesh of the present utility model
's.
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.A kind of combined type major diameter composite insulator hollow core rod is provided.
Technical solution of the present utility model is achieved in that this kind of combined type major diameter composite insulator hollow core
Rod, it is characterised in that hollow core rod (1) is by the glass epoxy pultruded rod thereon with through hole and/or blind hole more than a layer
One or/and glass epoxy pultrusion type rod two or/and glass epoxy pultruded rod three it is cured by glass epoxy mixture material or add
The hollow core rod of cured combination.
Of the present utility model beneficial has the technical effect that：As there is through hole and/or blind in the middle of the pultruded plug of skeleton
Hole, more closely solidification is combined as a whole from each other after each hole filling epoxy resin cure, makes plug internal intensity further
Strengthen, so as to greatly improve tension, compression strength.
Brief description of the drawings
Fig. 1 is the cross-sectional view of one embodiment of hollow core rod of the present utility model, and Fig. 2 is of the present utility model
The cross-sectional view of another embodiment, Fig. 3 is the longitudinal profile schematic diagram of the sequence number (2), (3) and (4) in Fig. 1 and Fig. 2.
Serial number in accompanying drawing：1st, hollow rod, 2, glass pultruded rod one, 3, glass pultruded rod two, 4, glass pultrusion
Type rod three, 5, through hole, 6, blind hole.
