Abstract
The utility model discloses a kind of major diameter core rod of insulator of nested structure, it is characterized in that it has plug and at least one outer tube, there is annular groove in the outer surface of plug, there is annular groove in the inner surface of outer tube, be molded by glass epoxy resin cure between plug and outer tube.Its advantage is that the outer surface of plug has annular groove, outer sleeve inner wall also has annular groove, poured or die casting between plug and outer tube and by glass epoxy resins insulation inserts between the annular groove of the two, by respective annular grooving and between gap by inserts solidification after be combined as a whole, plug internal intensity is set further to strengthen, so as to substantially increase tension, compression strength.Annular groove can also be reprocessed out in the outer surface of the above-mentioned plug for processing, the outer tube of a circle or set more multi-turn insulated solid pipe can be again covered according to above-mentioned thinking, to obtain the plug of larger diameter.For the manufacture of major diameter composite rod insulation provides a brand-new thinking and method.
Description
Technical field
The utility model belongs to the compound inslation subassembly in electric power facility, is specifically a kind of the big straight of nested structure
Footpath 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 as power transmission and transformation base parts and components, to ensure the stable operation of power transmission and transformation system.Relative to current
The technological level of pultrusion insulating bar, the composite electric insulator core bar of major diameter needs to be poured or die casting could meet need by secondary
Will, but, due to plug and pour or the material of die casting between can produce interface between crackle, shrink and bubble etc. lacks
Fall into, 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.A kind of major diameter core rod of insulator of nested structure is provided.
Technical solution of the present utility model is achieved in that the major diameter core rod of insulator of the nested structure, its
It is characterised by that it has plug and at least one outer tube, there is annular groove in the outer surface of plug, in the inner surface of outer tube
With annular groove, it is molded by glass epoxy resin cure between plug and outer tube.
Of the present utility model beneficial has the technical effect that：There is annular groove the outer surface of plug, and outer sleeve inner wall also has annular
Groove, pours or die casting between plug and outer tube and by glass epoxy resins insulation inserts between the annular groove of the two, will
Plug and outer tube by respective annular grooving and between gap be combined as a whole after inserts solidifies, make in plug
Portion's intensity is further strengthened, so as to greatly improve tension, compression strength.Can also be by the sleeve pipe of the above-mentioned plug for processing
Outer surface reprocess out annular groove, according to above-mentioned thinking can cover again circle or more enclose insulated solid pipe outer tube,
To obtain the plug of larger diameter.For the manufacture of major diameter composite rod insulation provides a brand-new thinking and method.
