Description
Technical field
The utility model relates to transformer technology field, specially a kind of transformer monomer-type low pressure double-seal casing pipe.
Background technique
Currently, the low-tension bushing that main transformer uses in Domestic Transformers manufacturing is glue bead and cushion rubber etc., set
The exposure gradually aging in air for a long time of the glue bead on pipe top, at 80 degree or so, glue bead softens temperature when transformer works
Locking nut can be made to loosen, situations such as permeability occur, when the cushion rubber of casing top, in place due to decrement, as seeped
It can not fastened when oily, need detachable maintaining, cause to have a power failure, increase cost, for this purpose, it is proposed that a kind of transformer monomer-type
Low pressure double-seal casing pipe.
Utility model content
The purpose of this utility model is to provide a kind of transformer monomer-type low pressure double-seal casing pipes, to solve above-mentioned back
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of transformer monomer-type low pressure double density
Big envelope pipe, including casing, sleeve bottom are connected with lower cover by fixing bolt, and cannula tip is fixedly installed with deflation cover, puts
Gas hood inner cavity is equipped with sealing ring, and upper press cover is fixedly mounted in cover top of deflating, and upper press cover and cover junction of deflating are equipped with glue
Circle, upper press cover top are provided with link block, and lower cover bottom is provided with lower connecting block.
Preferably, casing is aluminium alloy casing, and casing profile is wavy.
Preferably, mounting hole there are four opening up is poised for battle on lower connecting block, and the aperture of mounting hole is one centimetre.
Preferably, sleeve outer wall is provided with nickel coating, and the section thickness of nickel coating is three millimeters.
Preferably, upper link block outer wall is spirally connected, and there are two connect bolt.
Compared with prior art, the utility model has the beneficial effects that the utility model bushing shell for transformer is when leaving the factory
Assembled good, when installation, does not need to dismantle, and when use does not have to assemble again, is being put into a sealing inside the deflation cover on casing top
Circle plays the role of sealing, deflates and is being put into a cushion rubber between cover and gland, plays secondary seal, solve sealing element
Exposure is easy aging in air and the problem of permeability cannot fasten again occurs in a sealing ring.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1, casing；2, fixing bolt；3, lower cover；4, it deflates and covers；5, sealing ring；6, upper press cover；7, cushion rubber；8,
Upper link block；9, lower connecting block.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of transformer monomer-type low pressure double density big envelope
Pipe, including casing 1,1 bottom of casing are connected with lower cover 3 by fixing bolt 2, and deflation cover 4 is fixedly installed at the top of casing 1,
4 inner cavities of deflation cover are equipped with sealing ring 5,4 top fixed installation upper press cover 6 of cover of deflating, and upper press cover 6 and 4 junctions of cover of deflating
Cushion rubber 7 is installed, link block 8 is provided at the top of upper press cover 6,3 bottom of lower cover is provided with lower connecting block 9.
Wherein, casing 1 is aluminium alloy casing, and 1 section of casing is wavy, and aluminium alloy casing has good thermally conductive
Property, convenient for the heat in casing 1 that sheds；
It is poised for battle mounting hole there are four opening up on lower connecting block 9, and the aperture of mounting hole is one centimetre, convenient in mounting hole
Casing 1 is fixed with connector by insertion bolt；
1 outer wall of casing is provided with nickel coating, and the section thickness of nickel coating is three millimeters, effectively improves 1 outer wall of casing
Corrosion resistance increases its service life；
Upper 8 outer wall of link block is spirally connected, and there are two connect bolt, the connection diameter of bolt and the mounting hole phase on lower connecting block 9
Adaptation, convenient for improving the interchangeability of components.
Working principle: the transformer has been assembled when leaving the factory with casing 1, and when installation does not need to dismantle, when use not
With assembling again, the sealing ring 5 that 4 inside of cover of deflating is arranged plays the role of sealing, is arranged between deflation cover 4 and upper press cover 6
Cushion rubber 7, plays secondary seal, solve sealing element exposure be easy in air aging and a sealing ring 5 there is permeability cannot
The problem of fastening again.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
