Abstract
The utility model relates to a kind of Industrial Frequency Transformer, comprise insulation shell, by day font iron core, insulated coil skeleton, the strip boss of both sides and coil, day font iron core, insulated coil skeleton, strip boss and coil are all arranged in insulation shell, two hard contacts are extended with from insulation shell, hard contact enters in strip boss after bending, and terminal pointing direction is parallel with the direction of extension of I type silicon steel sheet; Day font iron core is provided with at least one leakage field space iron core.The utility model is provided with at least one leakage field space iron core in the leakage field space of transformer, and leakage flux can be made to be significantly improved, and then improves transformer impedance.In addition, hard contact in the inner bending of strip boss, and terminal pointing direction with direction of extension parallel, because the direction of extension length of I type silicon steel sheet is longer, transformer whole is taken up room and diminishes, and then less take fabricating yard.
Description
Technical field
The utility model relates to field transformer, particularly relates to a kind of Industrial Frequency Transformer.
Background technology
Transformer is a kind of converting electric power and static electromagnetic device electric energy being delivered to another circuit from a circuit.EI transformer is a kind of common Industrial Frequency Transformer version, and its iron core is by " E " matrix and " " matrix stacks up I, is referred to as EI transformer according to its shape.
Current EI transformer can only realize general impedance, cannot realize high impedance, and more the shell of part EI transformer has and adopt plastics or ceramic material, easily damaged because of collision, and then may threaten the safety of user.In addition, existing EI transformer whole size is comparatively large, takies larger space.
Utility model content
The purpose of this utility model proposes a kind of Industrial Frequency Transformer, while can improving transformer impedance, reduces taking up room of Industrial Frequency Transformer.
For achieving the above object, the utility model provides a kind of Industrial Frequency Transformer, comprise insulation shell, the day font iron core be formed by stacking by E type silicon steel sheet and I type silicon steel sheet, insulated coil skeleton, be arranged on strip boss and the coil of winding on described insulated coil skeleton of described insulated coil skeleton both sides, described day font iron core, insulated coil skeleton, strip boss and coil are all arranged in described insulation shell, two hard contacts are extended with from described insulation shell, described hard contact is in the inner bending of described strip boss, and terminal pointing direction is parallel with the direction of extension of described I type silicon steel sheet, described day font iron core is provided with at least one leakage field space iron core.
Further, described leakage field space iron core is made up of permeability magnetic material and gap backing plate, and is positioned at the centre position of described day font iron core.
Further, the middle part extension of described E type silicon steel sheet is described leakage field space iron core.
Further, crashproof layer is respectively equipped with in the upper and lower surface of described insulation shell.
Further, described crashproof layer adopts fiber.
Based on technique scheme, the utility model is provided with at least one leakage field space iron core in the leakage field space of transformer, and leakage flux can be made to be significantly improved, and then improves transformer impedance, greatly reduce the stray loss of transformer, reduce the adverse effect of leakage field simultaneously.In addition, hard contact in the inner bending of strip boss, and terminal pointing direction with direction of extension parallel, because the direction of extension length of I type silicon steel sheet is longer, transformer whole is taken up room and diminishes, and then less take fabricating yard.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of an embodiment of the utility model Industrial Frequency Transformer.
Fig. 2 is the structural representation of the Sino-Japan font iron core of the utility model Industrial Frequency Transformer embodiment.
Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
See Fig. 1, 2, the transformer of the present embodiment comprises insulation shell 1, the day font iron core 2 be formed by stacking by E type silicon steel sheet 21 and I type silicon steel sheet 22, insulated coil skeleton 3, be arranged on strip boss 8 and the coil 4 of winding on insulated coil skeleton 3 of insulated coil skeleton 3 both sides, iron core 2, insulated coil skeleton 3, strip boss 8 and coil 4 are all arranged in insulation shell 1, two hard contacts 5 are extended with from insulation shell 1, hard contact 5 enters in strip boss 8 after bending, and terminal pointing direction is parallel with the direction of extension of described I type silicon steel sheet.Can see from figure, the top of hard contact 5 is perpendicular to insulated coil skeleton 3, then bending 90 degree is transformed into parallel with the direction of extension of I type silicon steel sheet 22, and this just makes transformer entirety on the width of left and right take up room to diminish, and then less takies fabricating yard.Consider that long hard contact easily fractures, strip boss can make hard contact meet strength and stiffness requirement.
This hard contact 5 is connected with insulated coil skeleton 3.Day font iron core 2 is provided with at least one leakage field space iron core 7.Owing to being provided with at least one leakage field space iron core in the leakage field space of EI type transformer, leakage flux can be made to be significantly improved, and then improve transformer impedance, greatly reduce the stray loss of transformer, reduce the adverse effect of leakage field simultaneously.
As shown in Figure 2, leakage field space iron core 7 is made up of permeability magnetic material 72 and gap backing plate 71, is positioned at a day centre position for font iron core 2.And day font iron core 2 to be formed by stacking by E type silicon steel sheet 21 and I type silicon steel sheet 22, and the middle part extension of E type silicon steel sheet 21 is leakage field space iron core 7.
Preferably, can arrange crashproof layer 6 respectively in the upper and lower surface of insulation shell, this crashproof layer 6 can avoid EI type transformer impaired because of collision, improves use safety.Crashproof layer 6 preferably adopts fiber.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to embodiment of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
