The transformer is a device for changing alternating voltage by using the principle of electromagnetic induction, and main components are a primary coil, a secondary coil and an iron core. In the technical field of common oil immersed transformer corrugated sheet manufacturing, an oil immersed transformer is used as power transmission and transformation equipment, and the application degree is quite wide. The corrugated sheet is used as a main component applied to most oil-immersed transformers and mainly used for compensating volume expansion or contraction of insulating oil caused by temperature change and dissipating heat.

In the prior art, a large number of technical problems exist in a common high-capacity oil-immersed transformer: in the prior art, when a common high-capacity oil-immersed transformer uses electricity in a peak period, the temperature rise is obviously high, so that internal insulation aging is caused, the insulation strength is reduced, and various potential safety hazards are easily caused.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a transformer corrugated sheet to solve the ordinary large capacity oil immersed transformer among the prior art who proposes in the above-mentioned background art when the power consumption peak period, the temperature rise is all obvious on the high side, leads to the internal insulation ageing, and dielectric strength reduces, causes the problem of various potential safety hazards easily.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a transformer corrugated sheet, includes box and corrugated sheet, the corrugated sheet equidistance distributes on the lateral wall of box, be provided with the inner groovy on the lateral wall of box, the inner groovy department at the box is connected to the corrugated sheet, the inside of box and the position that corresponds with the inner groovy are provided with the lug, the corrugated sheet includes the corrugated sheet body, the upper and lower surface of corrugated sheet body all is provided with sand grip and cell body, the ventilation hole has evenly been seted up to the inside of cell body.

Preferably, the box body and the corrugated sheet are welded or integrally cast.

Preferably, the cross section of the bump is arc-shaped or polygonal.

Preferably, the convex strips and the groove bodies on the corrugated sheet body are arranged in a staggered manner, and the convex strips and the groove bodies on the upper surface and the lower surface of the corrugated sheet body correspond to each other.

Preferably, the cross sections of the convex strips and the groove body are both elliptical.

Compared with the prior art, the beneficial effects of the utility model are that:

1) through the matching effect of the box body and the corrugated sheets, the internal temperature of the box body can be quickly led out through the corrugated sheets;

2) through the arrangement of the inner grooves, the corrugated sheets extend towards the interior of the box body, so that the heat contact surface between the corrugated sheets and the interior of the box body is increased, and through the arrangement of the convex blocks, the contact area can be further increased;

3) through the setting of sand grip and cell body for the area of contact of corrugated sheet body and outside air increases, thereby can be convenient for the forced air cooling effect.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural diagram of the corrugated sheet of the present invention.

In the figure: 1 box body, 2 inner grooves, 3 corrugated sheets, 31 corrugated sheet bodies, 32 convex strips, 33 groove bodies, 34 vent holes and 4 convex blocks.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Example (b):

referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a transformer corrugated sheet, includes box 1 and corrugated sheet 3, corrugated sheet 3 equidistance distributes on the lateral wall of box 1, be provided with inner grove 2 on the lateral wall of box 1, corrugated sheet 3 is connected in 2 departments of the inner grove of box 1, the inside of box 1 and the position that corresponds with inner grove 2 are provided with lug 4, corrugated sheet 3 includes corrugated sheet body 31, the upper and lower surface of corrugated sheet body 31 all is provided with sand grip 32 and cell body 33, ventilation hole 34 has evenly been seted up to the inside of cell body 33.

Further, the box body 1 and the corrugated sheet 3 are welded or integrally cast.

Further, the cross section of the bump 4 is arc-shaped or polygonal.
