Transformer core laminating method

Abstract

This invention relates to transformer iron core slice iterated method, which combines the one-slice iterated method and two and three slice iterated method organically. The invention is characterized by the following: adopting one-slice iterated method at the one sixth of the thickness of the iron column; adopting two-slice iterated method at the one sixth of the thickness of the iron column; adopting three-slice iterated method at the one third of the thickness of the iron column

Description

Technical field: [0001] The invention relates to an iron core lamination method of a transformer, which is especially suitable for the iron core lamination method of small and medium-sized transformer products. Background technique: [0002] In the transformer industry, the thickness of the transformer core is stacked up by layers of core sheets. Theoretically speaking, it is best to adopt the method of stacking one piece per layer. The method of stacking one piece is to adopt the method of stacking one core piece per layer at each level of the stacked core, but this method is not suitable for small and medium-sized It is not suitable for transformer production, because small and medium-sized transformer products are generally produced in large quantities, and the method of stacking one piece will increase the workload of stacking, increase a large number of operating hours, and the efficiency is too low. Therefore, in the actual production process, small and medium-sized t...

Problems solved by technology

However, the disadvantage of this lamination method is that the magnetic flux density distribution of each part of the iron core is not uniform, which will lead to the increase of transformer iron loss and no-load current, and affect the reliable operation of the product.
