Problems solved by technology

[0002] At present, the iron core of existing transformers is still made of traditional silicon steel sheet materials. Compared with amorphous alloy materials, the no-load loss and load loss of traditional silicon steel sheet materials are relatively large, so the energy-saving effect is poor.

Embodiment 1

[0013] A sealed amorphous alloy power transformer according to the present invention, the iron core of the transformer is made of amorphous alloy material, and the basic elements of the amorphous alloy include iron, nickel, cobalt, boron and carbon, and its weight The percentages are as follows:

[0014] Nickel: 2%;

[0015] Cobalt: 3%;

[0016] Boron: 10%;

[0017] Carbon: 8%;

[0018] The balance is iron.

[0019] Because the amorphous alloy material is an isotropic soft magnetic material, the magnetization power is small, and there is no structural defect that hinders the movement of the domain wall, and it is proved by experiments that the load loss of the present invention is reduced by 15% on the basis of the GB / T6451 standard value , The no-load loss is reduced by 70% based on the GB / T6451 standard group I value, so the use of amorphous alloy materials reduces the no-load and load losses of the transformer, and has the characteristics of safety, reliability, environ...

[0023] Cobalt: 1%;

[0024] Boron: 5%;

[0025] Carbon: 2%;

[0026] The balance is iron.

[0027] Experiments have proved that the load loss of the embodiment of the present invention is reduced by 12.5% ​​on the basis of the GB / T6451 standard value, and the no-load loss is reduced by 50% on the basis of the GB / T6451 standard group I value.

Embodiment 3

[0029] A sealed amorphous alloy power transformer according to the present invention, the iron core of the transformer is made of amorphous alloy material, and the basic elements of the amorphous alloy include iron, nickel, cobalt, boron and carbon, and its weight The percentages are as follows:
