Abstract
A kind of hollow combined insulator has full skirt outside epoxy cylinder, flange bore area is provided with the first injecting glue slot and the second injecting glue slot including the flange that epoxy cylinder, epoxy cylinder one end are set with；The end of epoxy cylinder is provided with the first seal groove and the second seal groove；First injecting glue slot and the first seal groove, which are correspondingly arranged, constitutes a cavity for glue note epoxide-resin glue, and the second injecting glue slot and the second seal groove, which are correspondingly arranged, constitutes another cavity for glue note epoxide-resin glue；First delta seal slot is arranged at the bottom of flange, and there is the second delta seal slot in the end of epoxy cylinder, and the first delta seal slot and the second delta seal slot form the combined triangular seal groove of a triangle, be used for silicone rubber for sealing sealing ring.The utility model is more more convenient than the prior art in the process of assembling because using the form of injecting glue, faster；The seal groove of triangle has been opened in bottom, is sealed with sealing ring, and sealing performance is more stable, and sealing effect is more preferable.
Description
Technical field
The utility model belongs to power transmission and transformation processing technique field, is related to a kind of hollow combined insulator of good seal performance.
Background technique
For a long time, the porcelain hollow insulator for occupying electric insulation leading position always, there is weight weights, volume
Greatly, explosive is broken, the problems such as shock resistance is poor, security performance is poor, and need to periodically remove contamination, and brings to installation and maintenance
Inconvenience, and since the characteristic of porcelain, explosion injury and pollution flashover jump electrification and cause the economic of over ten billion Yuan to damage to country every year
It loses, and hollow combined insulator can be widely used for arrester, SF6 mutual inductor, power capacitor, bushing shell for transformer and test dress
The major insulation body for setting equal high-voltage products is the ideal product that insulator and glass insulator are substituted in power transmission and transforming equipment.It should not break
It is broken, sealing performance, interface reliable in quality;With excellent heat-resisting quantity, ageing resistance, proof tracking and silicon rubber
Exclusive hydrophobicity and migration of hydrophobicity.Meanwhile the product stable mechanical performance is reliable, the perils such as no fracture, explosion
Occur, can preferably protect other running equipments.For ensureing that energy delivery safety and stability plays a significant role.It is hollow
Deficiency existing for composite insulator is: due to the deficiency of sealing performance, SF6 gas inside hollow insulator being caused to use
It can constantly leak in the process, reduce its service life.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, provide one kind can preferably realize it is close
Envelope effect makes more convenient during assembling, the more stable hollow combined insulator of sealing performance.
The technical solution of the utility model includes the flange of epoxy cylinder, epoxy cylinder one end suit, has full skirt, method outside epoxy cylinder
Blue bore area is provided with the first injecting glue slot and the second injecting glue slot；The end of epoxy cylinder is provided with the first seal groove and the second seal groove；
First injecting glue slot and the first seal groove, which are correspondingly arranged, constitutes a cavity for glue note epoxide-resin glue, the second injecting glue slot and second
Seal groove, which is correspondingly arranged, constitutes another cavity for glue note epoxide-resin glue；First delta seal slot, ring are arranged at the bottom of flange
There is the second delta seal slot in the end of oxygen cylinder, and the first delta seal slot and the second delta seal slot form the combination of a triangle
Delta seal slot is used for silicone rubber for sealing sealing ring.
First injecting glue slot and the second seal groove described in the utility model are combined into a complete injecting glue seal groove, use ring
The sealing of oxygen resin glue, the second injecting glue slot and the first seal groove are combined into another complete injecting glue seal groove, use epoxy resin
Glue sealing, combined triangular seal groove are placed silicone rubber O-ring and are sealed to it.
The utility model opens upper injecting glue slot under the premise of not influencing structural strength on flange inner hole, opens in flange base
The seal groove of triangle is opened and the corresponding injecting glue slot of flange inner hole in the outer surface of epoxy tube, the end of epoxy tube open and
The corresponding triangle seal groove of flange base, injecting glue slot are sealed using injecting glue, and triangle seal groove is sealed using sealing ring.
Compared with prior art, the utility model have it is following the utility model has the advantages that
1, more more convenient than the prior art in the process of assembling because using the form of injecting glue, it is faster.
2, the seal groove of triangle has been opened in bottom, is sealed with sealing ring, and sealing performance is more stable, and sealing effect is more
It is good.
3, it does not need to add other equipment, it is only necessary to one switching device of design installation in existing equipment, so that it may
To realize injecting glue, do not increase cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In attached drawing, 1, flange；2, the first injecting glue slot；3, the second injecting glue slot；4, epoxy tube；5, the first seal groove；6, second
Seal groove；7, combined triangular seal groove；8, silicone rubber O-ring.
Specific embodiment
In Fig. 1, the flange of epoxy cylinder, epoxy cylinder one end suit has full skirt outside epoxy cylinder, flange bore area open first
Injecting glue slot and the second injecting glue slot；The first seal groove and the second seal groove that the end of epoxy cylinder is opened；The inner hole and epoxy tube of flange 1
4 end cooperates suit, enables the first injecting glue slot 2 and the second injecting glue slot 3 and the second of epoxy tube 4 on flange 1
Seal groove 5 cooperates there are also the first seal groove 6 and corresponds to, and is sealed after corresponding to well with epoxide-resin glue, the bottom of flange
There is the first delta seal slot, there are the second delta seal slot, the first delta seal slot and the second delta seal slot in the end of epoxy cylinder
The combined triangular seal groove 7 an of triangle is formed, silicone rubber for sealing sealing ring 8 is used for.
