Abstract
The invention relates to a transformer core stepping and stacking method and belongs to the technical field of transformer manufacturing. According to the technical scheme, a one-two-three-four-five-six stepping and stacking mode in the background technology is replaced by a one-three-five-two-four-six stepping and stacking mode, the one-three-five-two-four-six stepping and stacking mode is stacking with step intervals, namely a first layer air gap position is unchanged and is a position of an air gap (1); a second layer air gap is at a horizontal position of an air gap (3), a third layer air gap is at a horizontal position of an air gap (5), a fourth layer air gap is at a horizontal position of an air gap (2), a fifth layer air gap is at a horizontal position of an air gap (4), and a sixth layer air gap position is unchanged and is a position of an air gap (6). The transformer core stepping and stacking method has the advantages of improving air gap distribution of laminated piece gaps, enabling the air gap distribution to be not concentrate as the stacking mode in the background technology, being capable of reducing magnetic field distortion degrees, increasing the overlapping length between two layers at junctions, accordingly increasing frictional forces between the laminated pieces at the junctions and improving mechanical strength of a whole core.
Description
Technical field
The present invention relates to a kind of transformer core stepping stacking method, belong to technical field of transformer manufacturing.
Background technology
The large-scale iron core of transformer industry all adopts six step stack modes, during the stepping stacking unshakable in one's determination of background technology, step-by-step system is generally 1-2-3-4-5-6, the namely air gap stepping of core lamination gap formation increases, with reference to accompanying drawing 1, the ground floor gap position is that air gap one, second layer gap position are that air gap two, the 3rd layer of gap position are that air gap three, the 4th layer of gap position are that air gap four, layer 5 gap position are that air gap five, layer 6 gap position are air gap six, and successively stepping raises step by step.The problem that background technology exists is: the air gap irrational distribution in lamination gap, the easy distorted in magnetic field; The lap of splice between seam crossing is two-layer is shorter, and the frictional force between the seaming position lamination is less, and whole mechanical strength unshakable in one's determination is lower.
Summary of the invention
The purpose of this invention is to provide a kind of transformer core stepping stacking method, the magnetic line of force distortion that improvement causes because of seam unshakable in one's determination, increase simultaneously the mechanical strength of seaming position unshakable in one's determination, improved the mechanical strength of integral body unshakable in one's determination, solve the problems referred to above that background technology exists.
Technical scheme of the present invention is:
A kind of transformer core stepping stacking method with the 1-2-3-4-5-6 stepping stacking mode of the progressively stack of background technology, changes the 1-3-5-2-4-6 stepping stacking mode of interval step number stack into; 1-2-3-4-5-6 stepping stacking mode is stack progressively: the ground floor gap position is that air gap one, second layer gap position are that air gap two, the 3rd layer of gap position are that air gap three, the 4th layer of gap position are that air gap four, layer 5 gap position are that air gap five, layer 6 gap position are air gap six; 1-3-5-2-4-6 stepping stacking mode is interval step number stack: the ground floor gap position is constant, it still is air gap one position, second layer gap position is at the horizontal level of air gap three, the 3rd layer of gap position is at the horizontal level of air gap five, the 4th layer of gap position is at the horizontal level of air gap two, the layer 5 gap position is at the horizontal level of air gap four, and the layer 6 gap position is constant, still is air gap six positions.
Good effect of the present invention: the air gap that has improved the lamination gap distributes, so that the air gap distribution is concentrated unlike background technology stack mode, can reduce distortion of field degree; Increase the lap of splice between seam crossing is two-layer, thereby strengthened the frictional force between the seaming position lamination, improved the mechanical strength of integral body unshakable in one's determination.
