Abstract
The utility model provides a dry-type transformer core structure belongs to transformer technical field. This iron core structure includes the silicon steel sheet of a plurality of superpositions, and the silicon steel sheet includes the body, has the function portion that a plurality of thickness are greater than the thickness of body on the body, and the function portion is protruding to one side of body. The utility model has the advantages of good heat dissipation effect, convenient installation and the like.
Description
Technical Field
The utility model belongs to the technical field of the transformer, a dry-type transformer iron core structure is related to.
Background
The core is the main magnetic circuit part in the transformer. Usually made by stacking hot-rolled or cold-rolled silicon steel sheets containing silicon in a high content and coated with an insulating varnish on their surface. The iron core and the coil wound on the iron core form a complete electromagnetic induction system.
Magnetic flux produces a large amount of heats, and the iron core of traditional structure does not have better heat dissipation function, and moreover, traditional iron core has smooth silicon steel sheet superpose to form, need arrange in order it when the equipment, ensures that each silicon steel sheet superpose is neat, and the step of aligning needs repetitive operation in the iron core installation, and is more time-consuming and laborious.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a dry-type transformer core structure to the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem how to make the iron core have better heat dissipation function.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides a dry-type transformer core structure, its characterized in that, this core structure includes the silicon steel sheet of a plurality of superpositions, the silicon steel sheet includes the body, have the function portion that a plurality of thickness are greater than the thickness of body on the body, the function portion is protruding to one side of body.
Because the thickness of the functional part is larger than that of the body, after the silicon steel sheets are stacked, a gap exists between body parts of adjacent silicon steel sheets, and therefore the iron core has a heat dissipation effect.
Due to the existence of the functional part, the positioning function is realized, and the silicon steel sheets are very convenient to mount.
In the above dry-type transformer core structure, the functional portion is in a circular block shape or a long strip shape.
Drawings
Fig. 1 is a schematic structural diagram of the present core structure.
Fig. 2 is an enlarged view of a portion a in fig. 1.
In the figure, 1, a body; 2. a functional section.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 and 2, the iron core structure includes a plurality of silicon steel sheets stacked one on another, the silicon steel sheets include a body 1, the body 1 is provided with a plurality of functional portions 2 with a thickness greater than that of the body 1, and the functional portions 2 protrude toward one side of the body 1; the functional part 2 is in a round block shape or a strip shape.
Because the thickness of the functional part 2 is larger than that of the body 1, after the silicon steel sheets are stacked, a gap exists between the parts of the body 1 of the adjacent silicon steel sheets, and therefore the iron core has a heat dissipation effect.
Due to the existence of the functional part 2, the positioning function is realized, and the silicon steel sheets are very convenient to mount.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
Claims (2)
