What is an amorphous alloy dry-type transformer?
Amorphous Alloy Dry - type Transformer is a kind of dry - type transformer that uses amorphous alloy material as the iron core. The amorphous alloy material has unique physical and chemical properties, which enable it to exhibit excellent performance in transformer applications. This kind of transformer is widely used in situations where high energy - efficiency and environmental - protection requirements are emphasized.
Basic Definitions:
Amorphous Alloy: An amorphous alloy is a metallic material with an amorphous structure, usually composed of elements such as iron, boron, and silicon. The atomic arrangement of this material does not have a fixed lattice structure, thus possessing unique physical and chemical properties.
Dry-type Transformer: A dry-type transformer is a type of transformer that does not use a liquid cooling medium (such as transformer oil). It usually adopts natural air cooling or forced air cooling.
Structural Characteristics:
Iron Core: The iron core made of amorphous alloy material has extremely low hysteresis loss and eddy current loss.
Coil: Usually wound with copper or aluminum wires, it has good electrical properties.
Insulation Materials: High-quality insulation materials such as epoxy resin are used to ensure the safety of the transformer operating under high voltage.
Cooling Methods: Generally, natural air cooling (AN) or forced air cooling (AF) is adopted. The appropriate cooling method is selected according to specific application requirements.
