Problems solved by technology

[0003] The transformer is mainly composed of an iron core and a coil. During the working process, the iron core will generate loss. This loss will convert part of the electric energy into heat energy, resulting in a great waste of power.
Moreover, this energy loss will also increase the temperature of the iron core. If the iron core works at high temperature for a long time, the insulating layer on its surface will age, further increasing the loss.

Abstract

The invention belongs to the production field of the power equipment and specifically relates to a high-carbon iron-based amorphous alloy transformer core and a manufacturing method thereof. The high-carbon iron-based amorphous alloy transformer core is characterized by being prepared from the raw materials of iron, carbon, silicon and boron by virtue of the following preparation steps: (1) weighing; (2) crushing and grinding; (3) mixing and stirring; (4) smelting; (5) melt-spinning; (6) annealing; (7) drawing and stamping; (8) stacking and fastening. The loss of the high-carbon iron-based amorphous alloy transformer core prepared by the manufacturing method in the working process is lower than that of an iron-based amorphous alloy core containing no carbon, and therefore, the waste of electric energy can be further reduced and the power supply efficiency can be improved; meanwhile, as the amount of heat generated by the core in the working process is low, an insulating material covering the core is less in ageing possibility and thus advantageous for increasing the service life of the transformer. The high-carbon iron-based amorphous alloy transformer core can be applied to the field of production of power equipment and has wide application prospect.
