Abstract

The utility model discloses a kind of hybrid core construction of Transformer, comprise: upper yoke lamination, lower yoke lamination and core limb sheet, described core limb sheet adopts the staggered superposition of blade inserting to form core limb, described core limb is placed on lower yoke lamination, and described upper yoke lamination docks with core limb sheet successively.By the way, it is short little with zero load that the utility model can take into account man-hour, and reduce costs.

Description

The hybrid core construction of Transformer

Technical field

The utility model relates to transformer technology field, particularly relates to a kind of hybrid core construction of Transformer.

Background technology

At present, the iron core of conventional Transformer (such as two posts or three posts, rectangle) adopts silicon steel sheet plate-inserting structure more, such structural advantage be the no-load loss of transformer and no-load current very little, but man-hour is longer.Require short occasion in man-hour, engineers has to Core Design to become lamination, and the no-load loss of such transformer will increase much than plate-inserting structure with no-load current, and noise is also difficult to ensure.

Utility model content

The technical problem that the utility model mainly solves is to provide a kind of hybrid core construction of Transformer, can take into account man-hour short little with zero load, and reduce costs.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the hybrid core construction providing a kind of Transformer, comprise: upper yoke lamination, lower yoke lamination and core limb sheet, described core limb sheet adopts the staggered superposition of blade inserting to form core limb, described core limb is placed on lower yoke lamination, and described upper yoke lamination docks with core limb sheet successively.

In the utility model preferred embodiment, described core limb comprises the first core limb sheet, the second core limb sheet and the 3rd core limb sheet, described first core limb sheet and the 3rd core limb sheet are superimposed upon the outside of upper yoke lamination, and the second core limb sheet is inserted in the inner side of upper yoke lamination.

In the utility model preferred embodiment, described first core limb sheet and the 3rd core limb sheet are superimposed upon the inner side of upper yoke lamination, and the second core limb sheet is inserted in the outside of upper yoke lamination.

The beneficial effects of the utility model are: the inserted sheet mode of the utility model transformer makes no-load loss and no-load current reduce, and noise is also very low simultaneously, can take into account man-hour few, and unloaded few performance, and reduce cost.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.

Refer to Fig. 1 to Fig. 3, the utility model embodiment comprises: a kind of hybrid core construction of Transformer, it is characterized in that, comprise: upper yoke lamination 1, lower yoke lamination 2 and core limb sheet 3, described core limb sheet 3 adopts the staggered superposition of blade inserting to form core limb 30, described core limb 30 is placed on lower yoke lamination 2, and described upper yoke lamination 1 docks with core limb sheet 3 successively.

Furtherly, refer to Fig. 4 and Fig. 5, described core limb sheet 3 comprises the first core limb sheet 31, second core limb sheet 32 and the 3rd core limb sheet 33, described first core limb sheet 31 and the 3rd core limb sheet 33 are superimposed upon the outside of upper yoke lamination 1, and the second core limb sheet 32 is inserted in the inner side of upper yoke lamination 1; Or inserted sheet conversely, described first core limb sheet 31 and the 3rd core limb sheet 33 are superimposed upon the inner side of upper yoke lamination 1, and the second core limb sheet 32 is inserted in the outside of upper yoke lamination 1.

The erection sequence of the hybrid core construction of the utility model Transformer: first by staggered for core limb sheet 3 superposition, after forming core limb 30, core limb 30 is wound around bag of reaching the standard grade, then core limb 30 will be placed on lower yoke lamination 2, finally by upper yoke lamination 1(and silicon steel sheet) dock with core limb sheet 3 successively, complete inserted sheet, after also can completing inserted sheet, then be wound around bag of reaching the standard grade on core limb 30.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
