Abstract
The utility model discloses a kind of hollow insulator of band edge closure set, including silicon rubber umbrella page, flange and insulation tube, described silicon rubber umbrella leaf is coated on insulation tube, and the two ends of insulation tube set flange, and the gap between flange and silicon rubber umbrella page sets RTV glue to seal；Joint between described flange and silicon rubber umbrella page sets end seal sheath.Described end seal sheath is step ring jacket.End seal sheath of the present utility model uses the material same with silicon rubber umbrella page, and by mould molding, can substantially improve the aesthetic property of hollow insulator outward appearance.The utility model is by end seal sheath so that internal RTV glue to be closed, RTV glue envelope is set to expose in atmosphere, so as to avoid the problems such as RTV glue seals aging, the cracking that direct ingress of air is caused, the service life of hollow insulator can be significantly lifted.
Description
Technical field
The utility model is related to the hollow insulator in a kind of power transmission system, particularly a kind of sky of band edge closure set
Core insulation.
Background technology
Insulator plays two basic roles in overhead transmission line, that is, supports wire and prevent electric current from going back to ground, this two
Individual effect must be guaranteed, various electromechanical stress caused by insulator should not be changed due to environment and electric load condition
And fail, otherwise insulator would not produce great effect, will damage use and the service life of whole piece circuit.
Existing hollow insulator includes silicon rubber umbrella page, flange and insulation tube, and described silicon rubber pack overlays on insulation
Guan Shang, the two ends of insulation tube set flange.In order to prevent insulation tube exposure in atmosphere, RTV (room temperature vulcanized silicon rubbers are utilized
Glue) the gap glue between flange and silicon rubber umbrella page is sealed.
But this technique has the following disadvantages：
1st, the color of RTV and silicon rubber umbrella page has certain difference, and during artificial gluing, it is impossible to very uniform, the meeting of smearing
Influence the aesthetic property of whole product；
2nd, RTV ageing resistance is very low, and several Nian Houhui produce the phenomenons such as cracking, and a certain amount of water can be entered at cracking
Point, and insulation tube is met performance after water and can significantly declined, therefore the use of whole insulator can be influenceed.
Utility model content
To solve the above mentioned problem that prior art is present, the utility model, which will design one kind, can prevent insulation tube sealing part from entering
Enter moisture, improve the service life of insulator, while the hollow insulation of the band edge closure set of the hollow insulator of appearance looks elegant again
Son.
To achieve these goals, the technical solution of the utility model is as follows：The hollow insulator of band edge closure set, including
Silicon rubber umbrella page, flange and insulation tube, described silicon rubber umbrella leaf are coated on insulation tube, and the two ends of insulation tube set flange,
Gap between flange and silicon rubber umbrella page sets RTV glue to seal；
Joint between described flange and silicon rubber umbrella page sets end seal sheath.
Further, described end seal sheath is step ring jacket.
Further, described step ring jacket inner surface larger interior diameter section is coated on flange, smaller internal diameter section
It is coated on silicon rubber umbrella page.
Further, the cylinder ends of described flange are step, and end seal sheath is coated on the step of outside, inner side
Step sets RTV glue envelope.
Further, the internal diameter of described step ring jacket inner surface larger interior diameter section is equal to the cylinder body end of flange
The external diameter of step on the outside of portion, the maximum outside diameter of step ring jacket is equal to the shell portion external diameter of flange.
Further, the internal diameter of the smaller internal diameter section of described step ring jacket inner surface is equal to silicon rubber umbrella page end
The external diameter at place.
Further, described step ring jacket outer steps are with round-corner transition.
Compared with prior art, the utility model has the advantages that：
1st, end seal sheath of the present utility model uses the material same with silicon rubber umbrella page, and by mould molding, can be with
Substantially improve the aesthetic property of hollow insulator outward appearance.
2nd, the utility model makes RTV glue envelope can not be exposed to sky by end seal sheath so that internal RTV glue to be closed
In gas, so as to avoid the problems such as RTV glue seals aging, the cracking that direct ingress of air is caused, can significantly it be lifted hollow
The service life of insulator.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is enlarged drawing at Fig. 1 A.
In figure：1st, flange, 2, end seal sheath, 3, silicon rubber umbrella page, 4, RTV glue envelope, 5, insulation tube.
Embodiment
The utility model is further described through below in conjunction with the accompanying drawings.As shown in Figure 1-2, band edge closure set is hollow
Insulator, including silicon rubber umbrella page 3, flange 1 and insulation tube 5, described silicon rubber umbrella leaf 3 are coated on insulation tube 5, insulation tube
5 two ends set flange 1, and the gap between flange 1 and silicon rubber umbrella page 3 sets RTV glue envelope 4；
Joint between described flange 1 and silicon rubber umbrella page 3 sets end seal sheath 2.
Further, described end seal sheath 2 is step ring jacket.
Further, described step ring jacket inner surface larger interior diameter section is coated on flange 1, smaller internal diameter section
It is coated on silicon rubber umbrella page 3.
Further, the cylinder ends of described flange 1 are step, and end seal sheath 2 is coated on the step of outside, interior
Side stage rank sets RTV glue envelope 4.
Further, the internal diameter of described step ring jacket inner surface larger interior diameter section is equal to the cylinder of flange 1
The external diameter of step on the outside of end, the maximum outside diameter of step ring jacket is equal to the shell portion external diameter of flange 1.
Further, the internal diameter of the smaller internal diameter section of described step ring jacket inner surface is equal to 3 ends of silicon rubber umbrella page
External diameter at portion.
Further, described step ring jacket outer steps are with round-corner transition.
Further, the thickness of described step ring jacket is 2-5mm.
Manufacture method of the present utility model is as follows：Specific size according to junction between flange 1 and silicon rubber umbrella page 3 is set
Corresponding end seal jacket mould is counted out, the end agreed with completely with gap size is processed using silicon rubber umbrella 3 identical materials of page
