Embodiment
Referring to Fig. 1-3, the invention provides a kind of lapped three-phase five-limb amorphous core device of cross section approximate circle, comprise two outer amorphous cores 110, two interior amorphous cores 120 and three coils 400, described each amorphous core is arranged in order, amorphous cores are side by side outside described two between the amorphous core in described two, the side arm of described adjacent amorphous core joins, the side arm that joins constitutes core limb, amorphous core sheet in described arbitrary amorphous core is divided into some overlap joint groups that are uneven in length, the two ends of same overlap joint group overlap mutually in bonding land unshakable in one's determination, form an overlap joint section 301, the overlap joint section of overlap joint group has a dislocation with the overlap joint section of adjacent overlap joint group on tangential direction unshakable in one's determination arbitrarily, dock mutually the internal layer termination that any outer termination that overlaps section is located on the overlap joint section in its outside, leave a slit 302 between the two, the lamination of described same amorphous core also has different width, the width of the lamination outside wherein being positioned at is greater than the width that is positioned at inboard lamination, the two ends of the cross section of described each core limb all are the shape that is similar to arc of intermediate projections, described each coil is enclosed within respectively on each self-corresponding core limb, and the two ends of each coil are respectively and the similar arc in described core limb two ends.
The section of laminating of described each overlap joint group is an alternate successively fixing angle or fixing distance on body tangential direction unshakable in one's determination, has formed the respectively stepped distribution of the section of laminating thus.
The short circuit seam of described adjacent overlap joint group is spacedly distributed on two opposite tangential directions respectively, forms the stepped distribution mode of two correspondences of the section of laminating therewith.
The section of laminating of described each overlap joint group can also be in the certain area coverage of a side of iron core, from inside to outside along definite tangential direction cycle arrangement unshakable in one's determination.Both from the starting point (point in the middle of can being usually, also can be this zone the starting point on this tangential direction or other in this zone more arbitrarily) sequence arrangement on this tangential direction, after being aligned to this zone finishing line, return this regional starting line again along this tangential direction sequence arrangement, so circulation has repeatedly all been arranged until described small seam.This arrangement mode, be adapted to the many situations of lamination number of packet, and can make on tangential direction unshakable in one's determination, to have bigger distance between the adjacent small seam,, improve performance unshakable in one's determination by increasing the distance and the number of packet that increases lamination on the tangential direction.
Can determine the grouping situation of lamination butt joint group according to the performance requirement of iron core.
The number of packet of lamination butt joint group is many more, and the complexity of processing is big more, but performance unshakable in one's determination is good more.
For guaranteeing performance unshakable in one's determination, should reduce the width of small seam as much as possible, the width of this seam determined by the girth unshakable in one's determination of corresponding lamination length and this lamination position, should consider the machining accuracy of manufacture process unshakable in one's determination simultaneously and add machining accuracy when installing coil in transformer factory.
