Description
Technical field
The utility model relates to a kind of folding core structures, and in particular to a kind of power transformer folding core structure.
Background technique
Power transformer is a kind of static electrical equipment, is for the alternating voltage (electric current) of a certain numerical value is become frequency
The equipment of the different voltage (electric current) of the identical another or several numerical value of rate.When first winding passes to alternating current, just generate
The magnetic flux of the magnetic flux of alternation, alternation is acted on by iron core magnetic conduction, and AC electromotive force is just induced in secondary winding.Secondary induction
The height of electromotive force is related with the number of a secondary winding the number of turns, i.e., voltage swing is directly proportional to the number of turns.
The iron core of power transformer is stacked made of pressing as multi-disc silicon steel sheet.The shortcomings that existing core structure: 1,
Iron core seam quantity is 6；2, iron core seam crossing air gap is larger；3, iron core no-load current and no-load loss are larger.
It is accordingly required in particular to a kind of power transformer folds core structure, it is above-mentioned existing to solve the problems, such as.
Utility model content
The utility model provides a kind of power transformer folding core structure, solves the problems in background technique.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
A kind of power transformer of the utility model folds core structure, including core body, the core body include iron core
Column, upper yoke and lower yoke, the upper yoke and lower yoke form the cyclic annular outside for being wrapped in two iron core columns, and iron core column,
Upper yoke and lower yoke constitute three-frame and three pole structure.
As a kind of optimal technical scheme of the utility model, coil windings are provided in the iron core column.
As a kind of optimal technical scheme of the utility model, the upper end yoke of the iron core column is arc structure, described
The upper end of the corresponding iron core column in the both ends of upper yoke is also arc structure.
As a kind of optimal technical scheme of the utility model, the lower end yoke of the iron core column is foldable structure, described
The lower end of the corresponding iron core column in the both ends of lower yoke is also foldable structure.
As a kind of optimal technical scheme of the utility model, core body is stacked pressing by multi-disc silicon steel sheet and forms.
The utility model beneficial effect achieved is: compared with prior art, passing through iron core column, upper yoke and lower yoke
The three-frame and three pole structure of composition, and the advantages of this structure: 1, iron core seam quantity is reduced to 1；2, reduce seam crossing air gap；
3, no-load current and no-load loss is effectively reduced, structure is simple, extremely uses, and realizes the purpose of this utility model.

Outside, and iron core column 10, upper yoke 20 and lower yoke 30 constitute three-frame and three pole structure.
Coil windings are provided in iron core column 10.
The upper end yoke of iron core column 10 is arc structure, and the upper end of the corresponding iron core column 10 in the both ends of upper yoke 20 is also round
Arc structure.
The lower end yoke of iron core column 10 is foldable structure, and the lower end of the corresponding iron core column 10 in the both ends of lower yoke 30 is also folding
Stack structure.
Core body is stacked pressing by multi-disc silicon steel sheet and forms.
A kind of this kind of power transformer folds core structure and passes through iron core column, upper yoke and lower iron compared with prior art
Yoke piece at three-frame and three pole structure, and the advantages of this structure: 1, iron core seam quantity is reduced to 1；2, reduce seam crossing gas
Gap；3, no-load current and no-load loss is effectively reduced, structure is simple, extremely uses, and realizes the purpose of this utility model.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
