Abstract
The invention provides a filling type stepping transformer core. The filling type stepping transformer core comprises at least one lamination layer. The lamination layer is formed by laminating a plurality of core layers. Each core layer comprises an upper sheet steel, a lower sheet steel and a core leg sheet. Two ends of the core leg sheet are respectively connected with the upper sheet steel and the lower sheet steel, and seams are formed at joints. The filling type stepping transformer core is characterized in that the lamination layer comprises eight core layers. Each core layer is stacked with the upper part longitudinal and the lower part transverse. The upper sheet steel, the lower sheet steel and the core leg sheet are each provided with location holes. Due to the special eight-step laminating manner of the upper sheet steels, the lower sheet steels and the core leg sheets, no-load loss and no-load current are lowered, and the service life of the transformer is prolonged.
Description
Technical field
The present invention relates to transformer technology field, be specifically related to a kind of filled type step-up transformer iron core.
Background technology
Transformer is the device of conversion alternating voltage, electric current and impedance, and transformer is all generally formed by solenoid coiling on iron core, and iron core is a vitals of transformer.The iron core of traditional transformer is adopted by steel disc three grades of lap manufactures to form, 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 the iron core of this structure, the magnetic line of force at the steel disc on seam crossing transverse crossing side, and does not pass through air gap, and the lamination only adjacent is saturated, and magnetic flux, just by air gap, causes that no-load loss is large, no-load current large and produce high noisy district.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provide a kind of filled type step-up transformer iron core, by the long-pending folded mode of special eight steppings of upper steel disc, lower steel disc and core column sheet, reduce no-load loss and no-load current, extend the life-span of transformer.In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The invention provides a kind of filled type step-up transformer iron core, comprise at least one stack layer, stack layer is made up of stacked the amassing of some iron cores, described iron core layer comprises steel disc, lower steel disc and core column sheet, described core column sheet two ends are connected with upper steel disc, lower steel disc respectively, junction forms seam, it is characterized in that; Described stack layer comprises eight layers of iron core layer, and each iron core layer adopts longitudinally upper, lower horizontal stack mode; The transversion malposition stepping at least 2.5mm of described iron core layer and adjacent iron cores layer, longitudinally dislocation stepping is between 2.5mm to 8.5mm; Described upper steel disc, lower steel disc and core column sheet are equipped with location hole.
Further, described upper steel disc, lower steel disc and core column sheet are wolfram steel sheet.
Further, described upper steel disc, lower steel disc and core column sheet are silicon steel sheet.
Further, described seam is full bias seam, and the angle between jointing line and upper steel disc is 45 degree.
Further, the transversion malposition stepping of described iron core layer and adjacent iron cores layer is 2.5mm, and longitudinally dislocation stepping is 2.5mm.
The invention provides a kind of filled type step-up transformer iron core, by the long-pending folded mode of special eight steppings of upper steel disc, lower steel disc and core column sheet, reduce no-load loss and no-load current, extend the life-span of transformer.
Accompanying drawing explanation
