With generally by glass fiber winding pipe or glass fibre pultrusion winding pipe, pipe interior insulation filler, silicon rubber umbrella skirt and upper laxative remedy
Orchid composition, the effect of support and insulation is provided for wire, electrical equipment, and the two effects must assure that, will otherwise influence electricity
The safe operation of Force system and product service life.
Existing Hollow Compound support insulator or（Real core）Core body in post composite insulator（Rod or pipe）Species is more,
After being generally inserted into many minor diameter plugs until filling up the inner chamber of pipe by real mandrel surface winding epoxy glass fiber, hollow pipe
Reinject to be inserted in epoxy resin, hollow pipe and install multi-layer airbag etc., the said goods pair in unsaturated Foamex, hollow pipe additional
Sealing requirements are not high, but real mandrel surface and epoxy glass fiber winding interlayer, the interface between hollow pipe and inside stuffing
Air gap is easily produced, it is larger to product reliability of operation, safety effects.And the first two class product is heavy, high cost, afterwards two class
Product processes are more complicated, and practical application is remained in problem.It is in Hollow Compound support insulator hollow pipe involved by this patent
Constant pressure and dry gas, without interface in pipe, simple production process, low cost need to mainly solve to manage the sealing problem of interior gas.And it is electric
The sealing structure of Force system composite post insulator is traditionally designed in the bottom surface of flange, the end face pressure with hollow epoxy tube
Tightening seal, but in longtime running, Hollow Compound support insulator is influenceed by the factor such as wind-force or earthquake, extreme typhoon, will be through
The big horizontal twisting force of multidirectional, intensity is often born, Hollow Compound support insulator is produced and is frequently rocked, may result in
Flange can produce wriggling to cause upper and lower relative displacement with glass fibre tube end so that the single sealing ring compress variation of design
Reduce, sealing effectiveness is progressively lost, ultimately result in end part seal failure and accident occurs.
The content of the invention
The utility model is for existing Hollow Compound support insulator sealing principle and the deficiency of structure design, there is provided one
Sealing structure stabilization is planted, can effectively prevent sealing structure from causing the Hollow Compound of seal failure because frequently rocking in longtime running
Support insulator.
To realize the utility model purpose, there is provided following scheme：A kind of Hollow Compound support insulator, including insulator
Body, insulator body includes the hollow pultrusion pipe of epoxy resin fiberglass, is coated on the hollow pultrusion of epoxy resin fiberglass
The silicon rubber umbrella skirt of tube outer surface and upper flange, the lower flange at the hollow pultrusion pipe two ends of epoxy resin fiberglass are socketed on,
It is characterized in that plug is equipped with real core epoxy sealing plug, glass epoxy in the hollow pultrusion pipe two ends of epoxy resin fiberglass
It is dry gas, real core epoxy sealing plug and the hollow pultrusion pipe internal surface phase of epoxy resin fiberglass in the hollow pultrusion pipe of fiber
Multiple tracks radial ring seal groove A is provided with the side of contact, sealing ring, glass epoxy are inlaid with annular seal groove A
The hollow pultrusion pipe two ends of fiber are set with upper and lower flange, and upper and lower flange is the aluminium alloy flange set of bottom end closure shape, upper and lower
Radial ring seal groove is provided with the inner surface that flange is in contact with the hollow pultrusion tube outer surface of epoxy resin fiberglass
B, is inlaid with sealing ring in annular seal groove B, radial ring seal groove A and annular seal groove B constitutes dual labyrinth sealing knot
Structure.
Preferably, the sealing ring in annular seal groove B to be embedded in flange inner surface hollow with epoxy resin fiberglass
It is first radial seal of product between pultrusion tube outer surface.This design of Sealing Structure in Hollow Compound support insulator by the wind
The factor such as power or earthquake, extreme typhoon influences, and often bears the big horizontal twisting force of multidirectional, intensity and produces and frequently rock
When, even if causing to insert the hollow pipe wriggling displacement in flange, design the sealing ring compress variation base in annular seal groove B
This is unaffected, is effective to ensure that good sealing effectiveness.
Preferably, annular seal groove A inner seal rings are arranged at real core epoxy sealing plug with epoxy resin fiberglass sky
It is the second radial seal of product between the inwall of heart pultrusion pipe.Design of Sealing Structure is in Hollow Compound support insulator herein
Because of the influence of the factor such as wind-force or earthquake, extreme typhoon, often bear the big horizontal twisting force of multidirectional, intensity and produce frequently
When rocking, the sealing ring compress variation of design can keep constant, reliably ensure the long term seal effect of sealing ring.Multiple tracks is close
The structure setting of seal, further increases the reliability of sealing.Meanwhile, solid epoxy sealing-plug and epoxy resin fiberglass
Hollow pultrusion bore size is designed for slide fit, the bending strength of whole product can be largely improved, when reduction is rocked
The side-play amount on Hollow Compound support insulator top.
The utility model beneficial effect：The utility model is by the sealed bottom of traditional Hollow Compound support insulator flange
Structure is changed to the hollow pultrusion pipe inside and outside wall multiple tracks radial seal structure of glass fibre, greatly improves the sealing property of product, it is ensured that
Product operational reliability, and by setting solid sealing-plug, it is also possible to increase the hollow pultrusion pipe of epoxy resin fiberglass
Bending strength, the side-play amount of hollow composite post insulator top ends when reduction is rocked.
