Abstract
The utility model discloses a kind of wall bushing of new construction, there is binding post (4) at the two ends of conducting rod (3), its outer surface has silicon rubber umbrella skirt (1) and mounting flange (2), it is characterised in that the sleeve pipe between silicon rubber umbrella skirt (1) and conducting rod (3) is to turn into the sleeve pipe that there is the ironed film (5) of layer of metal to be molded by curing process for cylinder type and its appearance by least one layer of glass epoxy resin pultrusion rod (6) concentric arrangement.Its advantage is that every circle drawing and extruding bar wraps around one or more layers pressure equalizing paper, voltage field strength is set to be more evenly distributed, and there is no the ironed film of wound form due to winding voltage field strength phenomenon pockety that is uneven or producing winding gap and produce, improve the functional reliability of wall bushing.It is greatly improved using the casing strength after pouring structure, is particularly suitable for current high pressure and the super, application of extra-high voltage wall feed-through sleeve, higher and higher extra-high voltage project, which has a good application prospect, is required to antidetonation rank from now on.
Description
Technical field
The utility model belongs to electric power power transmission and transforming equipment, is specifically a kind of wall bushing of new construction.
Background technology
It is the electric power wall bushing used at present, either traditional ceramics material or composite, due to technique
Reason has wall bushing low intensity, electric-field intensity distribution, particularly current ehv power transmission engineering
In due to the problem of wall bushing is present, and have influence on normal application.In order to overcome these problems, making for wall bushing is improved
With performance and the pressure-resistant and strength grade of raising wall bushing, designer of the present utility model has done to be 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 puts forward to overcome the problem of above-mentioned wall bushing is present.Provide
A kind of wall bushing of new construction.
Technical solution of the present utility model is achieved in that the wall bushing of the new construction, in conducting rod (3)
Two ends have binding post (4), and its outer surface has silicon rubber umbrella skirt (1) and mounting flange (2), it is characterised in that in silicon rubber
Sleeve pipe between full skirt (1) and conducting rod (3) is to turn into cylinder by least one layer of glass epoxy resin pultrusion rod (6) concentric arrangement
Type structure and its appearance have the sleeve pipe that the ironed film (5) of layer of metal is molded by curing process.
Of the present utility model beneficial has the technical effect that：Often circle drawing and extruding bar wraps around one or more layers pressure equalizing paper, makes electricity
Have a meeting, an audience, etc. well under one's control and be more evenly distributed by force, and without the ironed film of wound form due to winding electricity that is uneven or producing winding gap and produce
Strong phenomenon pockety of having a meeting, an audience, etc. well under one's control occurs, and improves the functional reliability of wall bushing.It is strong using the sleeve pipe after pouring structure
Degree is greatly improved, and is particularly suitable for current high pressure and the super, application of extra-high voltage wall feed-through sleeve, to the requirement of antidetonation rank from now on
Higher and higher extra-high voltage project has a good application prospect.
Brief description of the drawings
Fig. 1 is contour structures schematic diagram of the present utility model, and Fig. 2 is to show three layers of glass in Fig. 1 A-A profiles, figure
The structure of the ironed film composition of fine epoxy resin pultrusion rod and three-layer metal, thus, it is possible to provide enough promptings：From 1 layer of glass
The structure combination that fine epoxy drawing and extruding bar to multilayer is arranged.Fig. 3 be a kind of ironed film of metal partial cross section amplification after show
It is intended to, Fig. 4 is the signal after the partial cross section amplification for the ironed film of metal for papering wood-fibred paper or plastic film structures
Figure.
Serial number in accompanying drawing：1st, silicon rubber umbrella skirt, 2, mounting flange, 3, conducting rod, 4, binding post, 5, metal it is equal
Ironed film, 6, glass epoxy resin pultrusion rod, 7, silicone rubber sleeve.
Embodiment
The embodiment provided 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 wall bushing of this kind of new construction has binding post (4) at the two ends of conducting rod (3), and its outer surface has silicon rubber
Glue full skirt (1) and mounting flange (2), it is characterised in that the sleeve pipe between silicon rubber umbrella skirt (1) and conducting rod (3) is by least
Layer of glass fiber epoxy resin pultrusion rod (6) concentric arrangement turns into cylinder type and its appearance has the ironed film of layer of metal
(5) sleeve pipe being molded by curing process.
In order to mitigate the weight of sleeve pipe as far as possible, the ironed film (5) of described metal is rolling aluminum foil.Copper foil can also be used
Or the good metallic film of other ductility.
Simple for the convenience and technique of processing and fabricating, the ironed film (5) of described metal is rolling aluminum foil and wood-fibred
Paper mounts aluminium-foil paper entirely after full paper.Copper foil or the good metallic film of other ductility can also be used.
Same as above, the ironed film (5) of described metal is that the line of rolling aluminum foil and wood-fibred paper after line is papered is mounted
Aluminium-foil paper.Copper foil or the good metallic film of other ductility can also be used.
Same as above, the ironed film (5) of described metal is that rolling aluminum foil and polyester film or plastic sheeting are compound
Composite aluminium foil paper.Copper foil or the good metallic film of other ductility can also be used.
