Definitions
- the invention relates to a process for the production of ferromagnetic core laminations for electrical machines.
- an electromagnetic machine such as a power transformer or a throttle
- the cores of power and distribution transformers therefore often consist of grain-oriented, ferromagnetic silicon steel. This is necessary because of the wide, magnetic ⁇ from time-dependent flow in the core also produces electrical losses.
- reverse magnetization losses are generated by the cyclical reversal of the direction of magnetization in the core.
- eddy currents are induced in the core, which are oriented perpendicular to the propagating magnetic flux. To reduce the eddy current losses, therefore, transformer cores are not made solid, but instead from layered individual sheets of a grain-oriented ferromagnetic silicon steel.
- the core sheets in the way are treated to a verbes ⁇ serte grain orientation and surface treatment of the E- lektrobleche to form a vitreous insulating layer such.
- B. Fosterit is formed. Grain-oriented electrical steel is produced from cold-rolled hot strip. ⁇ glow cold rolling with intermediate decarbonization, crystallization and relaxation produces a regular metallurgical crystal structure with a distinct structural ⁇ preferred direction of magnetization. A surface treatment with magnesium oxide leads to the formation of an insulating, glassy covering layer (fosterite) during the crystallization annealing. The subsequent application of a phosphorus solution with subsequent drying forms a final insulating layer of (phosphate). The insulating coating is usually applied to both surfaces of the grain-oriented electrical steel.
- a reduction of the core losses is systematically ensured by an improved grain orientation and domain refinement by laser, etching or mechanical treatment.
- the reduction in the eddy current loss is influenced sentlich we ⁇ by the magnetically effective thickness of the core sheet. The thinner the core sheet, the lower the eddy current losses. To avoid the eddy current losses no massive transformer core is used, but the core of correspondingly thin electrical steel sheets constructed in layers.
- the manufacturing process is designed so that a core-oriented electrical steel is manufactured as a sometimes more cold ⁇ cold rolled hot strip and with ⁇ lichlich decarburization, crystallization and flash annealing a metallurgically modified crystal structure is generated with a pronounced preferred direction of magnetization.
- the surface treatment described above produces the iso-regulating ⁇ glassy cover layer (forsterite and phosphate).
- Such material used and treated electrical steel is hernit as invitation-independent role in a slitting line in Part roles ⁇ th. This is followed by a cross-division or punching the final laminations for the transformer core.
- the stamping process is carried out either within the Pro ⁇ zessline the longitudinal pitch of the electric tape or under a separate punching process.
- the core sheets thus punched are then stacked manually or automatically in a core laying apparatus to form a transformer core.
- US 2002/0158744 A1 describes an apparatus and a method for producing large transformers with layered core sheets.
- US Pat. No. 6,416,879 B1 discloses a corresponding iron-containing material composition as starting material for the production of core laminations in order to minimize the magnetization losses and the eddy current losses in a core layered with this material.
- the object of the present invention is therefore to provide a method which makes it possible to produce core sheets of lesser thickness, which are also suitable for a mechanical requirement. Stress such as As in Kernlege shareholders not reduce their electro ⁇ magnetic properties.
- a first electrical strip and at least one second electrical strip made of a ferromagnetic material are at least partially enveloped by at least one insulating layer and the insulating layer of the first electrical strip of the insulating strip Layer of the second electrical steel by means of a compound ⁇ layer are interconnected.
- the use of a bonding layer between the individual electrical tapes has the advantage that the core sheets produced in this way have a layered structure and thus significantly reduce the eddy current losses in a core layered with the core laminates according to the invention.
- the core sheets produced by the method according to the invention are constructed from a layer of electrical tapes.
- the bonding layer ensures that the layered structure of the electrical steel strips of a core sheet also withstands the mechanical stress of the core sheet, such as in the manufacturing process or in the stress and thus mechanical stress of the core.
- the insulating layer is a layer deck ⁇ metallurgically produced, in particular of forsterite or fayalite. It is considered an advantage that the bonding layer between the insulating layers is an adhesive layer.
- the use of a fixing substance between the individual electrical tapes ensures on the one hand a permanent connection between the insulation layers and thus the individual electrical tapes. The eddy current losses can be significantly reduced.
- the core sheets a high mechanical stability ⁇ formality own and can be used in the production process without any restrictions.
- the bonding layer must permanently resistant to mine ⁇ ralöl, midel and silicone, temperature resistant in the range - 75 0 C to +200 0 C and highly adhesive to be electrical steel.
- Lami ⁇ nate of fixed electrical steel sheets must be flexible and workable in the generally usual longitudinal and cross cutting process. The hardness of the fixing layer must not lead to increased signs of wear on the core sheet cutting tools.
- the compound layer is a metallurgically forth ⁇ asked layer between the insulating layers, which is generated in particular by temporarily crystallization annealing.
- An insulating layer on an electrical steel sheets core for conventionally by a metallurgical Be ⁇ the surface of the electrical steel strip, for example, processing by pickling or etching the surface produced. Since heat treatments of the electrical tapes are also necessary for the formation of an insulation layer on the surface, the previous production methods can also be used for the production of a bonding layer between the individual insulation layers.
- the insulating layer and / or the compound layer know to a mechanical structure to me chanical stability contributes ⁇ of the core sheet.
- the mechanical stability of the Ver ⁇ binding layer can be increased. This also applies to the Use of different materials as a fixing substance for forming a bonding layer.
- the insulating layer can also be mechanically reinforced by the addition of a further grid layer and / or by location-dependent surface treatment of the electrode walls.
- the first electrical steel strip is covered with an insulation layer, then a bonding layer is applied to the insulation layers on the top and bottom side of the electrical strip and a second electrical strip is applied to the top and bottom of the insulation layers of the electrical strip is with enveloping insulation ⁇ layer on the first electrical steel by means of press rollers being ⁇ suppressed.
- the magnetic strip and / or the insulating layer and / or the call ⁇ varied in the core sheet layer, so that structural and / or electromechanical conditions can be taken into account in the layer structure of the Kernble ⁇ surface.
- Lamination can be used to tare into existing manufacturing processes integ ⁇ . Either as a lamination of two or more single-ply rolls to a laminated full roll, with the laminated roll serving as the starting material for the split process. Alternatively, the lamination of two or more single-ply width-cut part-width rolls into a laminated part-width roll may be performed, the laminated part-width roll being the starting material for the subsequent cross-cut process (punching process). It is also conceivable that the lamination of two or more punched individual sheets to form a laminated core sheet.
- the method according to the invention offers the advantage that a smaller sheet thickness than conventionally used (sheet metal thickness ⁇ 0.23 mm) is usable. This makes it possible Errei ⁇ chen a systematic reduction of the eddy currents in the core at constant design and manufacturing effort. Moreover, the method according to the invention requires no change in the previous core sheet manufacturing processes and the existing core laying processes.
