People can find that the eddy current loss (iron loss) of the coil wound by the students using a ring core is the smallest, so the iron core of the transformer is designed and processed into a ring.The iron core of the transformer is composed of silicon steel sheets. In order to reduce the heat loss in the iron core, the iron core is stacked with silicon steel sheets with a thickness of 0.23-0.5mm.The silicon content of the silicon steel sheets used in the transformer is relatively high.Both sides of the silicon steel sheets are coated with insulating varnish, so that the stacked silicon steel sheets can be insulated from each other. The thickness of the insulating varnish is only a few microns.Amorphous magnetic rings are magnetic components processed with 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.High-voltage DC power supply is also called DC high-voltage power supply. It is a power supply with AC mains or three-phase power input and DC voltage output of more than thousands of volts or tens of thousands of volts. The output power ranges from hundreds of watts to several kilowatts, and it can generally stabilize voltage or current.The iron core of the toroidal transformer is made of cold-rolled silicon steel sheets with different thicknesses of less than 0.35mm, which are seamlessly rolled into shape.The coil structure is evenly wound on the iron core, and the direction of the magnetic lines of force generated between the coils is almost completely inconsistent with the iron core magnetic circuit, which realizes the minimum cost of the large eddy current loss generated by the AC directly passing through these coils.The core loss is reduced by more than 50% compared with the U-type and E-type transformers, thereby improving the conversion efficiency of transformer technology or social isolation.
