Description

Double-layer sand-filled oil tank of transformer

Technical Field

The utility model relates to a double-deck husky oil tank of filling of transformer belongs to the transformer field.

Background

The noise of the transformer mainly comes from magnetostriction, coil electromagnetic sound, iron core vibration and the like during iron core excitation, the oil tank of the common oil-immersed transformer is a single-layer oil tank, and the noise is transmitted outwards after passing through the single-layer tank wall. The existing common noise reduction method is to improve the processing and manufacturing process of the transformer, but the noise reduction method has limited effect due to the performance defects of raw materials.

SUMMERY OF THE UTILITY MODEL

The utility model provides a double-deck husky oil tank of filling of transformer has solved the limited problem of current noise reduction method effect.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:

the utility model provides a double-deck husky oil tank of filling of transformer, includes oil tank body and radiator, and oil tank body lateral wall includes inner wall and outer wall, and inner wall and outer wall enclose the synthesis and hold the cavity, and the upper end that holds the cavity is provided with the filter screen, and the filter screen will hold the cavity and cut apart into upper plenum and lower cavity, and the upper plenum intussuseption is filled with dry granule, and lower cavity intussuseption is filled with the sand, cavity under the one end embedding of radiator heat conduction post to the sand bed and the interior wall connection of cavity.

The width of the cover plate at the top of the accommodating cavity is larger than the distance between the inner wall and the outer wall.

One end of the cover plate is fixed with the inner wall, and the other end of the cover plate is suspended.

The particle size of the dry particles is larger than the meshes of the filter screen.

The grain diameter of the sand is smaller than the meshes of the filter screen.

The dried granules do not fill the upper cavity.

The remaining space of the lower cavity, except for the receiving space of the heat-conducting column of the radiator, is filled with sand.

The sand is dry sand.

The utility model discloses the beneficial effect who reaches: 1. the side wall of the oil tank body is provided with the double layers, the thickness of the interlayer is set according to the actual noise reduction requirement, sand is filled in the interlayer, noise reduction is realized through the sand, and compared with the noise reduction improvement of a processing technology, the oil tank body has better effect and lower cost; 2. the utility model discloses set up the dry layer in the top on sand bed, after the sand wets, become vapor through the heat that transformer self gived off with the water in the sand, vapor rises the in-process and is absorbed by dry particle to guarantee the drying of sand, do not influence the noise reduction effect.

Drawings

fig. 2 is a schematic structural view of a side wall of the fuel tank.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in figures 1 and 2, the double-layer sand-filled oil tank for the transformer comprises an oil tank body and a radiator, wherein a side wall 2 of the oil tank body comprises an inner wall 4 and an outer wall 3, the inner wall 4 and the outer wall 3 enclose a containing cavity, and the distance between the inner wall 4 and the outer wall 3 is determined according to the actual noise reduction requirement and is generally located at 10 mm-40 mm.

The 6 width of apron at accommodation cavity top is greater than the interval between 4 and the outer wall 3 of inner wall, and concrete connection structure is: one end and 4 welded fastening of inner wall of apron 6, the body of apron 6 pastes with 3 tops of outer wall and leans on or welded fastening, and the other end of apron 6 is unsettled, can effectively shelter from the rainwater through convex apron 6.

The upper end of the containing cavity is provided with a filter screen 7, and the containing cavity is divided into an upper cavity and a lower cavity by the filter screen 7. The upper cavity is filled with dry particles 8, the particle size of the dry particles 8 is larger than the meshes of the filter screen 7, the upper cavity is not filled with the dry particles 8, and the dry particles 8 can still be contained in the upper cavity after absorbing water. Except for the accommodating space of the heat-conducting column of the radiator, the rest space of the lower cavity is filled with sand 5, the sand 5 is the dried sand 5, and the particle size of the sand 5 is smaller than the meshes of the filter screen 7.

One end of the radiator heat-conducting column 1 is embedded into the lower cavity and penetrates through the sand layer of the lower cavity to be connected with the inner wall 4.

The utility model discloses an oil tank body lateral wall 2 sets up the bilayer, will make an uproar the demand according to the reality, sets up intermediate layer thickness, is filled with sand 5 in the intermediate layer intussuseption, and it makes an uproar to realize falling through sand 5, compares in improving processing technology and falls, and the effect is better, and the cost is lower.

The utility model discloses set up the dry layer in the top on sand bed, after sand 5 wets, become vapor through the heat that transformer self gived off with the water in sand 5, the rising in-process of vapor is absorbed by dry particle 8 to guarantee the drying of sand 5, do not influence the noise reduction effect.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
