Abstract
A kind of hollow combined insulator, including insulator body, insulator body includes the hollow winding pipe of epoxy resin fiberglass, is coated on the silicon rubber umbrella skirt of the hollow winding tube outer surface of epoxy resin fiberglass and is socketed on upper flange, the lower flange at the hollow winding pipe two ends of epoxy resin fiberglass, upper and lower flange is aluminum alloy materials, end face insertion, axial annular seal groove A is provided between the end face that upper and lower flange bottom is in contact with the hollow winding pipe of epoxy resin fiberglass, sealing ring is inlaid with seal groove A；The inner surface that upper and lower flange winding tube outer surface hollow with epoxy resin fiberglass is in contact is provided with least one circle radial ring seal groove B, and sealing ring is inlaid with annular seal groove B.Sealing structure is reliable and stable, can effectively prevent hollow combined insulator in longtime running because frequently rocking the seal failure for causing.
Description
Technical field
The utility model relates generally to hollow combined insulator, is directed to 110kV and above cable end
The field of the electrical equipments such as end, transformer, breaker, power station disconnecting switch.
Background technology
Hollow combined insulator plays the important function such as insulation, support in power station, transformation device and electrical equipment out of doors, or
Power equipment is applied to as a building block of electric equipment.Generally by the hollow winding pipe of glass fibre, upper and lower flange and
Silicon rubber umbrella skirt is made, and the effect of support and insulation is provided for wire, electrical equipment, or as the external insulation of power equipment, and
The external force such as bending, stretching are undertaken, product must is fulfilled for these performance requirements, made with the operation safety and product that ensure power system
Use the life-span.
The sealing structure of existing hollow combined insulator is traditionally designed in the bottom surface of flange, the end with hollow epoxy tube
Face pressure tightening seal, but in longtime running, hollow combined insulator is by the factor such as wind-force or earthquake, extreme typhoon and operation vibrations
Influence, will often bear the big horizontal twisting force of multidirectional, intensity, produces hollow combined insulator and frequently rocks, and cause
Upper and lower flange can produce relative displacement with glass fibre hollow tube end because wriggling so that the single sealing ring compression of design becomes
Shape amount reduces, thus the sealing effectiveness of sealing ring is progressively weakened, and ultimately results in end part seal failure and accident occurs.
The content of the invention
A kind of deficiency of the utility model for existing hollow combined insulator design of Sealing Structure, there is provided sealing structure
It is reliable and stable, can effectively prevent sealing structure from causing the Hollow Compound of seal failure to insulate because frequently rocking in longtime running
Son.
To realize the utility model purpose, there is provided following technical scheme：A kind of hollow combined insulator, including insulator
Body, insulator body includes the hollow winding pipe of epoxy resin fiberglass, is coated on the hollow winding of epoxy resin fiberglass
The silicon rubber umbrella skirt of tube outer surface and the upper flange at hollow pipe two ends, lower flange are socketed on, upper and lower flange is aluminium alloy material
Axial direction is provided between material, end face insertion, the end face that upper and lower flange bottom is in contact with the hollow winding pipe of epoxy resin fiberglass
Annular seal groove A, sealing ring is inlaid with seal groove A, it is characterised in that upper and lower flange is hollow with epoxy resin fiberglass to be twined
The inner surface being in contact around tube outer surface is provided with least one circle radial ring seal groove B, and sealing is inlaid with annular seal groove B
Circle, axial annular seal groove A and radial ring seal groove B constitutes double sealing structure.
Preferably, the sealing ring in annular seal groove B is embedded in, flange inner surface is hollow with epoxy resin glass dimension to be twined
It is the second radial seal again of product around between tube outer surface.In hollow combined insulator because of wind-force or earthquake, extreme typhoon, shake
When the factor such as dynamic is often born multidirectional, powerful horizontal twisting force and produces frequent rocking, even if causing flange and epoxy
The hollow winding tube end of plexiglas fiber can produce relative displacement because wriggling, during the first resealing loss of seal effect of bottom,
Sealing ring compress variation in annular seal groove B is substantially unaffected, and can effectively keep the good sealing of whole product to imitate
Really, with make up the first resealing there may be failure defect.
The utility model beneficial effect：The utility model is by the bottom of traditional hollow composite insulator flange and glass fibers
Single axial design of Sealing Structure is improved to bottom and the hollow winding pipe end of glass fibre of flange between dimension hollow winding end surfaces
The radial direction between the hollow winding tube outer surface in axial direction, flange base medial surface and glass surface fiber between face adds sealing ring simultaneously
Double sealing structure is designed, and can effectively improve the sealing effectiveness of whole product, it is ensured that the reliability of product longtime running.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Specific embodiment
Embodiment 1：A kind of hollow combined insulator, including insulator body, insulator body include glass epoxy
The hollow winding pipe 1 of fiber, the silicon rubber umbrella skirt 2 for being coated on the hollow outer surface of winding pipe 1 of epoxy resin fiberglass and socket
Upper flange 3, lower flange 4 in the hollow two ends of winding pipe 1 of epoxy resin fiberglass, upper and lower flange（3、4）End face insertion, upper,
Lower flange（3、4）Axial annular sealing is provided between the end face that bottom surface is in contact with the hollow winding pipe 1 of epoxy resin fiberglass
Groove A, is inlaid with sealing ring 5, upper and lower flange in seal groove A（3、4）With the hollow outer surface of winding pipe 1 of epoxy resin fiberglass
The inner surface being in contact is provided with least one circle radial ring seal groove B, and sealing ring 5, axial rings are inlaid with annular seal groove B
Shape seal groove A and radial ring seal groove B constitutes double sealing structure.
Upper and lower flange inside diameter is interference fit with the hollow winding pipe outside diameter size of epoxy resin fiberglass,
First to the appropriate heating of flange during assembling, while outer with flange junction in the hollow winding tube end of epoxy resin fiberglass
Surface coats one layer of bonding agent, and coating epoxy resin fiberglass corresponding with seal groove B leaves above hollow winding pipe position
Flange after heating, is then inserted in the hollow winding tube end of epoxy resin fiberglass by the distance of about 10mm, and compression makes method
Blue bottom surface winding end surfaces hollow with epoxy resin fiberglass are completely attached to, and keep pressure natural cooling to be completed after 3~5 minutes
Assembling.Adhesive coating can also play sealing function.
