Description
Technical field
The utility model relates to the casings of sealing structure, and in particular to a kind of set using horizontally disposed double sealing structure
Pipe.
Background technique
With the development of transformer technology, voltage class is higher and higher, and structure becomes increasingly complex, and casing is connection power grid
With the medium of transformer, just to bushing shell for transformer, more stringent requirements are proposed for this.It is interior for conductive rod type casing used at present
Portion is typically filled with insulating gas or liquid, keeps the pressure of inside pipe casing bigger, if the sealing performance of casing is bad at this time, holds
The leakage for easily causing gas or liquid causes the dielectric strength of casing to decline, punctures casing.So the sealing of casing for
It is vital to guarantee that the performance of casing plays the role of；Casing biggish for current-carrying, since the effect of conducting rod is current-carrying, when
When having high current to pass through conducting rod, conducting rod is easy fever, and the gasket arranged vertically is directly to contact with conducting rod, this
When high current caused by heat effect be easy to make gasket to melt, aging, make to seal ineffective；On the other hand it arranges vertically close
Packing is easy to produce compression seal phenomenon not in place, and the maximum pressure of inside pipe casing can reach 0.4MPa, and at this moment casing is just
Gas leakage is generated, the effect of sealing is not had.
Utility model content
In view of the above-mentioned problems, the utility model, which provides one kind, can eliminate the hidden danger of seal leakage and multiple
The casing using horizontally disposed double sealing structure of installation requirement under the complexity of heterocycle border.
To solve the above problems, the technical solution that the utility model is taken are as follows: a kind of to use horizontally disposed double sealing structure
Casing, including conducting rod, the compressed spring structure for being installed on conducting rod upper end, the pedestal for being installed on conducting rod end, from upper
Sequentially connected the first hollow combined insulator for being installed on conducting rod periphery under and, the second hollow combined insulator, ground connection cylinder,
It insulate under glass reinforced plastic；The pedestal is in the groove profile of opening upwards, and conducting rod ending vertical is pierced by slot bottom, insulate under glass reinforced plastic
It is placed in base notches；It is equipped with pedestal nut in Its lower side, conducting rod end passes through the pedestal nut；At pedestal nut and bottom
There is delta ring sealing gasket between seat, against the position of conducting rod is horizontally disposed；In the contact surface of pedestal nut and pedestal, in triangle
Shape gasket periphery is horizontally disposed rectangular seal pad.
Compressed spring structure includes compressed spring, spring nut, spring support, and compressed spring is located at spring support and conduction
In the space that bar is constituted, compressed spring lower end is contacted with spring support, and compressed spring upper end is connected with spring nut and spring spiral shell
Mother connect with conducting rod.
The delta ring sealing gasket is the sealing pad washer that cross section is right angled triangle, one of right-angle side and bottom
The fitting of seat downside, another right-angle side are bonded with conducting rod.
Triangle washer is being arranged close to the position of conducting rod in the application, which can generate axial seal again
Horizontal seal is generated, such casing is formed double sealing structure, increases bobbin seal reliability.Rectangular seal pad and triangle
What the compression of shape gasket was leaned on is the compressed spring structure on top, by adjustment spring nut, applies stressed size to adjust.
Apply pressure to gasket by compressed spring structure in the application to compress, the structure is simple, easy to operate
And the conventional techniques that pressure is bushing shell for transformer field are applied to gasket by compressed spring structure.
Usually compressed spring is in compressive state, and compressed spring passes through the upward bullet that spring nut generates compressed spring
Power has passed to conducting rod, and conducting rod is made to be in a state proposed upwards, and conducting rod is connected together with pedestal nut
, so that pedestal nut be made to be in a state proposed upwards, gasket is compressed, sealing is played the role of.
By up, adjustment spring nut down, the size of compressed spring elastic force may be implemented, to change pedestal nut
Stressed size is applied to gasket.
Delta ring sealing gasket nestles up conducting rod, and when electric current is lesser, delta seal pad can play sealing completely
Effect, short circuit is generated outside the transformer, this is short circuit current even thousands of times of hundreds of times of big decades of times than usual, at this time
There may be thawing or agings for delta ring sealing gasket.At this moment, peripheral rectangular seal pad plays second sealing defence line again
Effect.The upper surface of the pedestal nut has been arranged concentrically delta ring sealing gasket seal groove and rectangular seal pad limiting slot.
Since rectangular seal pad uses position limiting structure, gasket is prevented to be excessively stressed.
The application uses horizontally disposed rectangular seal pad and delta ring sealing gasket, avoids the work of heat caused by high current
Be easy to make gasket to melt, aging, make to seal ineffective；Casing is formed double sealing structure simultaneously, increases casing
Sealing reliability.Using the power of the compressed spring structure on casing top, gasket is compressed, double containment is played the role of.
