Abstract
A comprehensive stepping joint iron core for a transformer comprises an iron core layer, which is formed by laminating a plurality of steel sheets, wherein joint areas are arranged at two ends of the laminated steel sheets, and the steel sheets are in a 45-degree full-inclined longitudinal-lateral multi-step ladder-like arrangement in the joint areas. The longitudinal-lateral multi-step ladder-like arrangement is formed in a manner that at least nine steel sheets are taken as one group and are laminated with multiple longitudinal-lateral steps, wherein each lamination layer includes one steel sheet. The comprehensive stepping joint iron core for the transformer of the invention reduces designed flux density of steel sheets whose air gaps are adjacent through the longitudinal-lateral multi-step laminated arrangement of the steel sheets, and reduces no-load loss and no-load current, and the arrangement is more convenient for inserting and pulling out steel sheets, thereby improving work efficiency.
Description
Technical field
The present invention relates to transformer technology field, be specifically related to a kind of comprehensive stepping seam iron core for transformer.
Background technology
The device of transformer room's conversion alternating voltage, electric current and impedance, transformer is made up of iron core or magnetic core and coil, and coil has two or more winding, and wherein connect the winding of power supply primary coil, remaining winding is secondary coil.When being connected with alternating current in primary coil, in iron core or magnetic core, just producing exchange flux, making in secondary coil, to induce voltage or electric current.In transformer manufacturing traditional at present, lamination adopts the stack mode of laterally three steppings, and the iron core adopting this technology father to synthesize is 1.414 times of close B of iron core column magnetic by the close BG of magnetic of the adjacent steel disc of air gap, and the number of times that on average every layer of steel disc passes through air gap is twice.In this structure, the magnetic line of force is at the steel disc on seam crossing transverse crossing side, and generation eddy current and magnetic are satisfied, and form high loss and strong noise district.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provide a kind of comprehensive stepping seam iron core for transformer, by the mode of the special steel disc of many stepping stackings in length and breadth thus to reduce the design magnetic of the adjacent steel disc of air gap close, reduce no-load loss and no-load current, and it is convenient that this mode plugs steel disc, improves operating efficiency.In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The invention provides a kind of comprehensive stepping seam iron core for transformer, comprise iron core layer, iron core layer is formed by multilayer steel disc stack, it is characterized in that: the steel disc two ends after stack are provided with seam region, steel disc in seam region adopts 45 degree of complete oblique multisteps in length and breadth to enter step arrangement, it is be one group by least every nine steel discs that described multistep in length and breadth enters step arrangement, and a slice one is folded, and multistep is entered in length and breadth; The transversion malposition stepping of described iron core layer and adjacent iron cores layer is between 2mm to 4mm, and longitudinally dislocation stepping is between 1.5mm to 3.5mm; Described steel disc is wolfram steel sheet or silicon steel sheet.
Further, described steel disc is equipped with location hole.
Further, the transversion malposition stepping of described iron core layer and adjacent iron cores layer is 2.5mm, and longitudinally dislocation stepping is 3mm.
Further, it is be one group by 10 steel discs that described multistep in length and breadth enters step arrangement, and a slice one is folded, ten steppings in length and breadth.
Further, the angle between the first steel disc jointing line after stack to the 10th steel disc jointing line is 45 degree.
A kind of comprehensive stepping seam iron core for transformer provided by the invention, by the mode of the special steel disc of many stepping stackings in length and breadth thus to reduce the design magnetic of the adjacent steel disc of air gap close, reduce no-load loss and no-load current, and it is convenient that this mode plugs steel disc, improves operating efficiency.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for specification, together with embodiments of the present invention for explaining the present invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of comprehensive stepping seam iron core for transformer of the present invention;
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Be illustrated in figure 1 the structural representation of a kind of comprehensive stepping seam iron core for transformer of the present invention, comprise iron core layer, iron core layer is formed by multilayer steel disc 1 stack, it is characterized in that: steel disc 1 two ends after stack are provided with seam region 3, steel disc in seam region 3 adopts 45 degree of complete oblique multisteps in length and breadth to enter step arrangement, multistep enters step arrangement is in length and breadth be one group by least every nine steel discs, and a slice one is folded, and multistep is entered in length and breadth.The transversion malposition stepping of iron core layer and adjacent iron cores layer is between 2mm to 4mm, and longitudinally dislocation stepping is between 1.5mm to 3.5mm.From selection, steel disc 1 is wolfram steel sheet or silicon steel sheet.In order to reach better effect, steel disc 1 is equipped with location hole 2.Transversion malposition stepping through test of many times discovery iron core layer and adjacent iron cores layer is 2.5mm, and when longitudinally dislocation stepping is 3mm, effect is very good, and no-load loss at this time and no-load current are very low.In addition, find by 10 steel discs to be one group through test of many times, a slice one is folded, ten steppings in length and breadth, and when first steel disc jointing line to the angle between the 10th steel disc jointing line after stack is 45 degree, effect is the best.
A kind of comprehensive stepping seam iron core for transformer provided by the invention, by the mode of the special steel disc of many stepping stackings in length and breadth thus to reduce the design magnetic of the adjacent steel disc of air gap close, reduce no-load loss and no-load current, and it is convenient that this mode plugs steel disc, improves operating efficiency.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
