Transformers are the most important power equipment in the entire power grid.In addition to converting AC voltage, special transformers have various other uses, such as changing the frequency of power supply, the power supply of rectifier equipment, the power supply of welding equipment, the power supply of electric furnaces, or as voltage transformers, current transformers, etc. Amorphous magnetic rings are magnetic components processed from amorphous materials.Amorphous magnetic rings can be divided into iron-based amorphous, cobalt-based amorphous, etc. according to the different materials of the amorphous strips used.The transformer core is composed of silicon steel sheets. In order to reduce the heat loss in the core, the core is stacked with silicon steel sheets with a thickness of 0.23-0.5mm.The silicon content of silicon steel sheets used in transformers is relatively high.Both sides of the silicon steel sheets are coated with insulating paint, so that the stacked silicon steel sheets can be insulated from each other. The thickness of the insulating paint is only a few microns.The efficiency of the transformer is very high, but due to the large capacity and large number, the loss of the transformer is also very high. The loss of the transformer mainly comes from the iron loss of the transformer core and the copper loss of the winding.According to statistics, the total loss of the transformer accounts for about 10% of the system power.
