Study of Amorphous alloy
The invention discloses an amorphous alloy transformer which comprises a box, and a high-voltage electric pole and a low-voltage electric pole which are disposed on the box. A cover is disposed on the box. The amorphous alloy transformer is characterized in that a 15KV-20KV transformer high-voltage coil is disposed in the box, the amount of the main coils of the high-voltage coil is 1-2 times of that of the sub-coils of the high-voltage coil, the main coils and the sub-coils are distributed at two ends of the high-voltage coil, the tap points of the main coils and the sub-coils are connected with branch control switches between the high-voltage electric pole and the low-voltage electric pole, and a double-layer rubber plate is disposed at the base plate at the bottom of the box. By using the branch control switches, high-low voltage change is achieved, and capital and resources for repeatedly purchasing a large amount of equipment are saved.
