    Abstract: High-efficiency and energy-saving is the development trend of transformers. The current high-efficiency and energy-saving distribution transformers mainly use amorphous alloy core transformers and three-dimensional wound core transformers. This paper expounds the development of a high-efficiency and energy-saving laminated core distribution transformer, that is, by using the latest high-quality and high-performance silicon steel sheets, a series of technical measures have been taken to reduce losses in the core and winding structure of the distribution transformer. Focusing on comparing the actual measurement of the losses in the low-voltage winding with the calculated value,the reason for the difference between the measured value and the calculated value is analyzed. The accuracy of the model simulation results is verified through the product electromagnetic simulation analysis and the actual measurement results, which provides technical support for the development of the subsequent series of high-efficiency and energy-saving distribution transformers.
    Key words: high-efficiency and energy-saving; laminated core; distribution transformer; double-layer foil winding
