With the continuous innovation of science and technology, energy saving and consumption reduction, intelligent and environmental protection have become the mainstream of the development of modern power transformers. Recently, Russian scientists have developed a new generation of methods that can reduce the energy consumption of transformers and engines by nearly 70% (66%), that is, using a new type of iron-based amorphous alloy as the core material. The performance of the developed transformer is far better than that of ordinary materials. Similar products are advanced and are a new generation of high-tech transformer products.

The key component of a transformer is its iron core. Part of the electric energy will be converted into heat energy when flowing through the iron core, and the energy consumption during the transformation process mainly occurs in the iron core. This form of energy consumption accounts for 3.5% of the total energy consumption in the world every year.

As the global natural resources are depleted but the demand for electricity is rising, it may be possible to solve the energy-saving problem by manufacturing amorphous alloys.

Amorphous alloy, or metallic glass, is a new type of material that came out in the 1970s. It is a solid alloy (thin ribbon) obtained by forming molten steel into a thin strip with a thickness of 30 microns at one time using quenching technology. It is different from the crystal structure in which the atoms are regularly arranged in cold-rolled silicon steel materials. It is this alloy whose atoms are in an irregularly arranged amorphous structure, which makes it have a narrow BH loop, high permeability and low loss; at the same time; The irregular arrangement of atoms in amorphous alloys restricts the free passage of electrons, resulting in a resistivity that is 2-3 times higher than that of crystalline alloys, which is also conducive to reducing eddy current loss. Compared with traditional transformers using silicon steel sheets, the no-load loss of the transformer core made of amorphous alloy is reduced by about 75%, so that the amorphous alloy transformer has a very significant energy saving and environmental protection effect. When the transformer core is used in an oil-immersed transformer, it can significantly reduce a variety of harmful gases. Therefore, more and more manufacturers use amorphous alloys as raw materials for transformer cores.
　　 According to scientists: When the temperature reaches 1300 degrees Celsius, the alloy will flow to a rotating copper disk and quickly cool to form an amorphous ribbon, the thickness of which is only 3/4 of the diameter of a human hair. However, the current manufacturing cost of the transformer core body made of the new alloy will be 30% higher than that of the traditional transformer, and further technical improvements can be made. According to calculations, if all the power transformers in Moscow are replaced with iron-based amorphous alloy transformers, about 20 million U.S. dollars can be saved each year. After three to five years of using this type of transformer, the savings in energy consumption can offset the additional costs. .
