Description
Technical Field
[0001] The utility model relates to the field of transformers, in particular to an iron core for energy-saving transformers. Background Art
[0002] The iron core is one of the important parts of the transformer. It is mainly used to conduct and concentrate the magnetic field, thereby realizing the principle of electromagnetic induction transformer. The iron core is usually composed of multiple laminated silicon steel sheets. Energy-saving transformers are more energy-saving and efficient than traditional transformers. Energy-saving transformers mainly improve the overall energy efficiency of transformers by reducing iron loss, copper loss and no-load loss.
[0003] However, the iron core of most traditional energy-saving transformers is cooled by the transformer casing, which makes the transformer less effective in cooling the iron core, thereby generating a higher temperature around the iron core. The high temperature will cause additional losses in the iron core and windings of the transformer, resulting in reduced energy efficiency and affecting the overall energy-saving effect.
