Abstract
The utility model discloses a kind of hollow combined insulators, including insulation tube, the equal empty set in both ends of insulation tube is connected to flange, there is not isometrical gap between the inside of flange and the outer wall of insulation tube, and epoxy glue layer is provided between flange and insulation tube, which can bear larger tensile stress.
Description
Technical field
The utility model belongs to electric power electric field, is related to a kind of hollow combined insulator.
Background technology
The application range of the development of power equipment in recent years, hollow combined insulator is also more and more extensive, no longer only makees
For the purposes of insulating supporting, a large amount of uses especially in circuit electrical equipment are also subjected to higher tensile stress in operation.
Hollow combined insulator mechanical performance additionally depends on the mucilage binding structure of product other than the material property dependent on product itself.
The Joining Technology of hollow composite insulator flange 1 and insulating part uses epoxy adhesive mucilage binding technique, i.e. flange inner cavity and insulation
2 outer wall of pipe is assembled to form mucilage binding structure interval, and structure interval is filled by epoxy adhesive as connection, however existing insulator energy
The tensile stress enough born is smaller, is susceptible to damage.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts provides a kind of hollow combined insulator,
The insulator can bear larger tensile stress.
In order to achieve the above objectives, hollow combined insulator described in the utility model includes insulation tube, the both ends of insulation tube
Equal empty set is connected to flange, there is not isometrical gap between the inside of flange and the outer wall of insulation tube, and between flange and insulation tube
It is provided with epoxy glue layer.
External insulation umbrella sets are provided on the outer wall of insulation tube, the end of external insulation umbrella sets is in contact with flange.
The cross section of flange inner wall is in terraced structure, with not isometrical gap described in formation.
The flange is cast aluminium flange.
Insulation tube is epoxy fibreglass winding pipe.
The side of insulation tube is provided with annular groove, the inner wall of the annular groove face flange.
The utility model has the advantages that：
Hollow combined insulator described in the utility model is when specific operation, the outer wall in the inside of flange and insulation tube
Between there is not isometrical gap, and be provided with epoxy glue layer between flange and insulation tube, keep epoxy in drawing process glued
The shearing stress distribution that oxidant layer and flange are subject to is in different radial anchor rings, to improve tensile stress that insulator can be born
Size makes insulator be less prone to damage, and simple in structure, easy to operate, practicability is extremely strong, and can effectively improve product can
By property.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1 be flange, 2 be insulation tube, 3 be external insulation umbrella sets, 4 be not isometrical gap.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
With reference to figure 1, hollow combined insulator described in the utility model includes insulation tube 2, the equal empty set in both ends of insulation tube 2
It is connected to flange 1, there is not isometrical gap 4 between the inside and the outer wall of insulation tube 2 of flange 1, and between flange 1 and insulation tube 2
It is provided with epoxy glue layer.
External insulation umbrella sets 3 are provided on the outer wall of insulation tube 2, the end of external insulation umbrella sets 3 is in contact with flange 1；Flange 1
The cross section of inner wall is in terraced structure, with not isometrical gap 4 described in being formed；Flange 1 is cast aluminium flange；Insulation tube 2 is epoxy
Glass fiber winding pipe；The side of insulation tube 2 is provided with annular groove, the inner wall of the annular groove face flange 1；From the end of insulation tube 2
To on the middle part direction of insulation tube 2, the size in isometrical gap 4 is not gradually reduced.
The specific preparation process of the utility model is：The processing for first carrying out flange 1, is then assembled to insulation tube 2 by flange 1
On, make to form not isometrical gap 4 between flange 1 and insulation tube 2, then fills epoxy hardener into not isometrical gap 4, then into
Row heating, completes the solidification of epoxy hardener.
