Good Property Better Permeable Iron Core Used For Oil-immersed Transformer And Dry Type Transformer

  The part of the winding in the iron core is called the "heart column", and the part that does not cover the winding and only plays the role of a magnetic circuit is called the "iron yoke". Where the iron core surrounds the winding, it is called the shell type, and where the winding surrounds the core column, it is called the core type. Shell type and core type have their own characteristics, but the transformer manufacturing process determined by the iron core is very different, once a certain structure is selected, it is difficult to produce a structure. Most of the transformer cores in China adopt the stacked core type.

   Generally, it is a stacked iron core, which is made of stacked iron cores. There are many forms of coiled iron cores. The air gap between the core column and the yoke of the involute core is large, which affects the no-load current, so the capacity cannot be too small; However, because the leakage magnetic flux enters the plane of the iron chip vertically, affecting the additional loss, the width of the piece should not be too large, that is, the capacity should not be too large.
