Description
Technical field
The present invention relates to a kind of end seal structure of super extra-high voltage combined insulator, belong to insulator technology field.
Background technology
With the development of power industry, super UHV transmission line dodges ability and end for the anti-soil of composite insulator
The requirement more and more higher of sealing property.In composite insulator running, the end part seal of composite insulator directly affects it
The safety of interior insulation performance, if insulator end seal failure, extraneous steam, filth can invade sheath and plug interface and corruption
Erosion plug, so as to the risk along sheath and plug interface breakdown occur, and can cause the corrosion brittle failure of plug, threaten operation of power networks
Safety.
The end seal structure of composite insulator is broadly divided into integrated sealing structure and combined seal structure, puts into practice table
Bright, the former is simple compared with latter process, be adapted to streamlined operation, and control point is few, reliability is higher, and most of composite insulators are adopted
Use integrated sealing structure.However as the raising of transmission line of electricity voltage class, existing end seal structure can not be good
Meet the requirement of the machinery, electric property higher of super extra-high voltage combined insulator.Therefore, for super extra-high voltage combined insulator
Requirement and deficiency of the prior art, further improve composite insulator end seal structure, improve end part seal performance
And reliability, for ensureing that insulator long-term safety operation tool has very important significance.
The content of the invention
The present invention is directed to drawbacks described above, it is therefore intended that providing one kind further improves insulator end sealing property and reliability
Property, ensure the operation of insulator long-term safety a kind of super extra-high voltage combined insulator end seal structure.
For this technical solution adopted by the present invention is：The present invention includes being arranged on plug（4）Metal level on the outside of one end（3）
And it is arranged on plug（4）Restrictive coating on the outside of the other end（1）, the metal level（3）And plug（4）Outer surface, restrictive coating（1）
And plug（4）Outer surface forms sealing, the metal level（3）And restrictive coating（1）Relative end forms sealing.
The restrictive coating（1）End is by the metal level（3）In end is coated on, the faying face at both ends forms plug-in
Coordinate.
The metal level（3）End forms following structure type：Terminal interior surface forms the ring-shaped step hole of indent（31）,
End sides are formed and are more than metal level（3）The annular convex surface of external diameter（32）, the metal level（3）Adjacent annular convex surface（32）'s
Position is provided with less than metal level（3）The groove of external diameter（33）；
The restrictive coating（1）The profile of end and the metal level（3）End profile is correspondingly arranged, and both ends form clamping
Formula sealing coordinates.
The annular convex surface（32）To be similar to the arc surface of sphere.
The restrictive coating（1）End and metal level（3）Contact position set fluid sealant（2）.
It is an advantage of the invention that：a）Metal-ware, plug, be coated on plug and metal-ware end it is high temperature vulcanized
Silicone rubber jacket passes through physics, is connected chemically together, is permanent seal；
b）" concave-convex-recessed " labyrinth sealing path compared with existing sealing structure, effectively increases end part seal performance；
c）Metal-ware end is using the bulge-structure for being similar to sphere, the tip surface right angle with traditional metal-ware end
Compare, the electric stress that can greatly reduce metal-ware end is concentrated, it is to avoid is caused point discharge, is effectively overcome insulator metal
Infringement of the annex caused by discharging to sheath and plug, improves the reliability of insulator end seal structure under operation
Property；
d）It is coated on plug and the high-temperature silicon disulfide rubber sheath of metal-ware end and the umbrella cover of insulator is global formation
, and thickness is almost equal, seamlessly transits with the thickness of insulator sheath, it is ensured that under identical manufacturing process the former
Vulcanization uniformity, reduce interface, while can prevent end seal structure because vulcanize it is uneven caused by internal flaw, for example
Over cure, undervulcanization or poor attachment, it is ensured that the q＆r of end seal structure；
e）While the room temperature vulcanization silicon rubber sealant of sealing part is in further raising sealing effectiveness, can avoid contact with
Interface accumulation is filthy, rainwater.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
1 is restrictive coating in figure；2 is fluid sealant；3 is metal level；4 is plug；
31 is ring-shaped step hole, 32 is annular convex surface, 33 is groove.
Specific embodiment
The present invention includes the sheath for being arranged on the metal level 3 on the outside of the one end of plug 4 and being arranged on the outside of the other end of plug 4
Layer 1, the metal level 3 and the outer surface of plug 4, restrictive coating 1 and the outer surface of plug 4 form sealing, the metal level 3 and restrictive coating
1 relative end forms sealing.
In be coated on for the end of the metal level 3 by the end of the restrictive coating 1, the faying face at both ends forms plug-in and matches somebody with somebody
Close.
The end of the metal level 3 forms following structure type：Terminal interior surface forms the ring-shaped step hole 31 of indent, end
Side formed more than the external diameter of metal level 3 annular convex surface 32, the metal level 3 adjoining annular convex surface 32 position be provided with it is small
In the groove 33 of the external diameter of metal level 3；
The profile and the end profile of the metal level 3 of the end of the restrictive coating 1 are correspondingly arranged, and both ends formation plug-in is close
Envelope coordinates.
The annular convex surface 32 is the arc surface for being similar to sphere.
The contact position of the end of the restrictive coating 1 and metal level 3 sets fluid sealant 2.
As shown in figure 1, plug 4 is plugged in metal level 3, both are linked together by first time pre-crimping.In plug 4
With the end brushing coupling agent of metal level 3, high-temperature silicon disulfide rubber filling metal-ware end interior or exterior space, sulfidization molding is sheath
Layer 1.After second specified crimping is carried out, room temperature vulcanization silicon rubber sealant 2 is being smeared.
Metal level of the present invention 3 is assemblied in the end of plug 4, by crimping, metal level 3 end and core permanently connected with plug 4
The interface of rod 4 is permanent seal.
It is coated on plug 4 and the high-temperature silicon disulfide rubber restrictive coating 1 of the end of metal level 3 is overall with the umbrella cover of insulator
Sulfidization molding, restrictive coating 1 is bonded together with plug 4 and the end of metal level 3 by coupling agent, and the adhesive strength at its interface is big
It is permanent seal in sheath pulls intensity.
Another feature for being coated on the high-temperature silicon disulfide rubber restrictive coating 1 of plug 4 and the end of metal level 3 is：It is thick
Degree is almost equal with the thickness of insulator sheath, and seamlessly transits.
