Lapped amorphous core with approximate-circle cross-section

Abstract

The invention relates to a lapped amorphous core with an approximate-circle cross-section. The lapped amorphous core is formed by packing a plurality of amorphous core plates in sequence and is characterized in that the amorphous core plates are divided into a plurality of lapped groups with different lengths, the two ends of one lapped group are lapped at the bonding land of the core to form a lapped section, the lapped section of any lapped group has one misplacement with the lapped section of the adjacent lapped group along the tangential direction of the cores, the outer-layer end of any lapped section is lapped with the inner-layer end of the lapped section arranged outside the any lapped section, and a gap is kept between the outer-layer end and the inner-layer end; the amorphous core plates also have different widths, and the amorphous core plates in the middle of a core limb are wider than the amorphous core plates at the two sides of the core limb. The lapped amorphous single core of the invention has good effect of magnetic conduction, is not only beneficial to saving the usage of copper in a coil but also beneficial to preventing the insulating materials of the coil from being damaged by extrusive corner angles and is mainly used in various amorphous transformers.

Description

technical field [0001] The invention relates to an amorphous single iron core with an overlapping cross-section that is approximately circular, and belongs to the field of electrical technology. technical background [0002] The amorphous iron core is stacked together by several layers of amorphous iron core sheets to form a closed electromagnetic field circuit, which is used to transmit magnetic flux on transformers and other equipment. Coils are placed on the iron core columns on both sides of the iron core. Variable magnetic field, the magnetic flux of this magnetic field is transmitted to another coil through the iron core to form an induced current, thereby realizing the function of energy transfer and voltage transformation. At present, the width of each layer of amorphous iron core in the amorphous iron core is the same. The cross-section thus formed is rectangular, and the annular coil sleeved on the iron core column should also be rectangular, so as to adapt to the ...
