Amorphous double cores with single coil and approximate-circle cross-section

Abstract

The invention relates to amorphous double cores with a single coil and an approximate-circle cross-section, comprising two parallel amorphous cores and a coil. The amorphous cores are rectangular rings with four bent corners; the adjacent side limbs of the two amorphous cores form a core limb; and the coil is sheathed on the core limb. The amorphous cores are formed by packing a plurality of amorphous core plates, wherein, the amorphous core plates of one amorphous core have different widths, and the core plates arranged outside are wider than the core plates arranged inside. The two ends of the cross-section of the core limb take the shape which is similar to arc with the middle part raised; and the two ends of the coil respectively take the shape of arc which is similar to the two ends of the core limb. The amorphous double cores of the invention have compact structure, are not only beneficial to saving the usage of copper in the coil but also beneficial to preventing the insulating materials of the coil from being damaged by extrusive corner angles and are mainly used in corresponding amorphous transformers.

Description

technical field [0001] The invention relates to an amorphous double iron core with a cross-section approximate to a circle provided with a single coil, which belongs to the field of electrical technology and can be mainly used for various multi-core transformers. technical background [0002] The amorphous iron core used in multi-core transformers is stacked together by several layers of amorphous iron core sheets to form a closed electromagnetic field loop for transmitting magnetic flux. Coils are placed on the iron core columns on both sides of the iron core. After the coil is energized, it generates Alternating magnetic field, through the iron core, the magnetic flux of this magnetic field is transmitted to another coil to form an induced current, thereby realizing the function of energy transfer and voltage transformation. At present, the width of each layer of amorphous core sheets in the same amorphous core is the same. Yes, the cross-section of the side arm of the iro...
