S (B) H15 Series 10KV oil immersed amorphous alloy core distribution transformer

1、 Overview

The iron core of amorphous alloy iron core distribution transformer is made of non-metallic alloy strip with soft magnetic characteristics, which can further reduce the distribution loss and reduce air pollution. Compared with the traditional silicon steel AC voltage transformer, this new transformer can reduce the no-load loss by 75% and has a high-efficiency energy-saving effect.

The iron-based amorphous alloy iron core has the characteristics of low loss (equivalent to 1 / 3-1 / 5] of silicon steel sheet), low coercivity, low exciting current, high resistivity and good temperature rise stability. The no-load loss of transformer made of amorphous alloy iron core is 70-80% lower than that of S9 product series made of silicon steel sheet, and the no-load current is 20% lower than that of S9 series.

Amorphous alloy is a new type of energy-saving material. It takes iron, boron and other elements as materials for rapid extremely cold solidification production process. Its unreasonable state shows that the metal yard is in disordered amorphous arrangement. It is completely different from the crystal structure of silicon steel and is more conducive to cup magnetization and demagnetization. This new material is used in transformer core. The demagnetization and magnetization process of 100-120 times per second is quite easy when the transformer is running Thus, the no-load loss of iron core is greatly reduced. If used in oil immersed transformer, it can also reduce harmful gases such as CO, so and NOx, which is known as the "green material" of the 20th century.

S (b) H15 amorphous alloy iron core distribution transformer products, the iron core adopts single frame or three-phase five column wound core, the core is solid and tight with thin plate forming frame structure, and the low-voltage coil is foil Rao type, which has low loss, strong short-circuit resistance, advanced and reasonable structure, and the overall performance indication has reached the world advanced level.
