Abstract
The utility model aims at providing a transformer bushing's flange seal structure, the problem of oil leak probably takes place for the main flange of solving current transformer bushing. It includes insulation core body, flange, sealing washer, flange piece, set screw, it bonds to fill back solidification through the casting glue between insulation core body and the flange, be equipped with the sealing washer in the cyclic annular triangular groove that insulation core body, flange and flange piece formed, the flange piece passes through set screw and flange joint. The utility model discloses an it is effectual sealed to increase the one deck, has improved the oil leak condition between transformer bushing flange and insulation core body well, has guaranteed transformer bushing's flange seal.
Description
Technical field
This utility model relates to the flange sealing structure of a kind of bushing shell for transformer.
Background technology
At present, in bushing shell for transformer produces, the gap between insulation core body and flange commonly uses casting glue
Solidification carries out bonding and seals, and has reached the requirement of mechanical strength and adhesive strength, but has existed on sealing
Following shortcoming: one be this structure production method be casting glue natural flow blind, casting glue flows over
In journey, viscosity becomes rapidly big, and casting glue possibly cannot be filled up completely with gap, and gap forms passage will leakage of oil；
Two is that flange contact facings existing defects or coupling agent are brushed uneven, causes flange and casting glue loose contact, seam
Gap forms passage leakage of oil；Three is that casting glue allotment is uneven, and a small amount of casting glue can not be fully cured bonding and shape
Become passage leakage of oil；Four is that this structure production process has irreversibility, occurs that leakage of oil is difficult to repair.
Utility model content
For the problems referred to above overcoming general bushing shell for transformer flange arrangement to exist, the purpose of this utility model
Being to provide a kind of bushing shell for transformer flange arrangement, this structure has been effectively ensured the sealing of bushing shell for transformer flange.
The technical scheme in the invention for solving the technical problem is, the flange of a kind of bushing shell for transformer
Seal structure, including insulation core body, flange, sealing ring, flange plate and fixing screw, it is characterized in that insulation
It is bonding that core body irrigates gap solidification between it with flange by casting glue, insulation core body, flange and flange plate shape
It is provided with sealing ring in the annular triangular groove become, reaches good by compresses seal on the three of triangular groove directions
Good sealing effectiveness, flange plate, by fixing screw and Flange joint, is effectively fixed.
Further, insulation core body, flange and sealing ring, flange plate on same central shaft, insulation core body,
Flange and the annular triangular groove of flange plate formation rule, sealing ring uniform stressed in three directions.
Further, described sealing ring is O RunddichtringO.
Further, the triangular groove that insulation core body, flange are formed with flange plate is a size of located at sealing therein
Circle is total to the 20% to 30% of compression seal loop diameter in three directions.
Further, flange connecting hole is tapped blind hole, for adpting flange sheet.
Further, the connecting hole of flange plate is counterbore or through hole.
The beneficial effects of the utility model are: the flange sealing structure of this utility model bushing shell for transformer, pass through
Increase by one layer of effective sealing, improve the leakage of oil situation between bushing shell for transformer flange and insulation core body well,
Ensure that the flange seal of bushing shell for transformer.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model；
Fig. 2 is the partial enlarged drawing in Fig. 1 at A；
In figure, 1-insulation core body, 2-flange, 3-sealing ring, 4-flange plate, 5-fix screw.
Detailed description of the invention
Below in conjunction with the accompanying drawings 1 and accompanying drawing 2 describe embodiment of the present utility model in detail.
The flange sealing structure of a kind of bushing shell for transformer, flange 2 is filled out by casting glue after being set with insulation core body 1
Fill the groove solidification between the bucket wall of flange 2 and insulation core body 1 bonding, set inside the card of described flange 2
Have cascade groove, flange plate 4 to be arranged at the cascade groove of flange 2, insulation core body 1, flange 2 with
Flange plate 4 intermediate formation annular triangular groove, is provided with sealing ring 3 in triangular groove.
Insulation core body 1, flange 2 and sealing ring 3, flange plate 4, can be with formation rules on same central shaft
Annular triangular groove, sealing ring 3 uniform stressed in three directions.
Sealing ring 3 uses O RunddichtringO, O RunddichtringO to make three stress surfaces reach identical sealing effectiveness,
It it is a kind of cost-effective measure.
By calculating the size of design triangle groove, make the triangle that insulation core body 1, flange 2 are formed with flange plate 4
Groove is a size of located at sealing ring 3 therein and is total to the 20% to 30% of compresses seal 3 diameter in three directions,
Sealing ring 3 is in good sealing state.
Flange plate 4 has equally distributed counterbore or through hole, and in flange 2 groove, correspondence opens tapped blind hole, method
Blue sheet 4 is fixing with flange 2 tight by fixing screw 5, thus reaches the effect of compresses seal.
