Abstract
The invention provides a hybrid stepping joint iron core for a transformer. The hybrid stepping joint iron core comprises a core layer. The core layer is formed by laminating a plurality of layers of sheet steel. The hybrid stepping joint iron core is characterized in that two ends of the laminated sheet steels are each provided with a joint area. The sheet steels in the joint area are in 45-degree all-inclining hybrid stepping ladder-like arrangement. According to the hybrid stepping arrangement, eight sheet steels make up a group, the first to third sheet steels staggered by vertical steps of 2mm, the fourth sheet steel and the third sheet steel are staggered by a vertical step of 6mm, and the fifth to eighth sheet steels are in staggered by vertical steps of 2mm. In the hybrid stepping joint iron core, the core in the transformer adopts 45-degree all-inclining hybrid stepping arrangement, so that no-load loss and no-load current are lowered, furthermore, manpower and material resources are saved.
Description
Technical field
The present invention relates to transformer technology field, be specifically related to a kind of mixing stepping seam iron core for transformer.
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 mixing stepping seam iron core for transformer, the method of step arrangement is entered by the iron core in transformer being adopted 45 degree of complete tiltedly mixing steps, not only reduce no-load loss and no-load current, and save manpower and materials.In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The invention provides a kind of mixing 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 tiltedly mixing steps to enter step arrangement, it is be one group by 8 steel discs that described mixing step enters step arrangement, 1st to the 3rd steel disc longitudinal dislocation stepping is 2mm, 4th steel disc and the 3rd longitudinal stepping that misplaces of steel disc are 6mm, and the 5th to the 8th steel disc longitudinal dislocation stepping is 2mm.
Further, described steel disc is equipped with location hole.
Further, described steel disc can be silicon steel sheet.
Further, described steel disc also can be wolfram steel sheet.
Provided by the inventionly provide a kind of mixing stepping seam iron core for transformer, by being adopted by the iron core in transformer 45 degree complete oblique mixing steps to enter the method for step arrangement, not only reducing no-load loss and no-load current, and saving manpower and materials.
