What is the relationship between the overload capacity of the Amorphous Alloy Dry Type Transformer and its structural design?

The overload capacity of the Amorphous Alloy Dry Type Transformer is closely related to its structural design.
The amorphous alloy core is the core structural component of this transformer. Amorphous alloy materials have unique magnetic properties, with narrow hysteresis loops and high magnetic permeability, which enables the transformer to effectively reduce core losses during normal operation. Under overload conditions, this material property helps the transformer maintain the stability of the magnetic field to a certain extent, providing a certain basis for overload operation. However, the heat dissipation performance of the amorphous alloy core is relatively poor because of its compact structure and low thermal conductivity. This requires that the structural design should consider adding heat dissipation paths. For example, a heat sink or forced air cooling structure is used to dissipate heat in time to avoid excessive core temperature due to heat accumulation and affect overload capacity. When a reasonable heat dissipation design is adopted, the amorphous alloy dry-type transformer can maintain relatively stable performance during overload, and its overload multiple and overload time can be effectively improved.
The winding structure also has an important influence on the overload capacity. Parameters such as the material, diameter and number of turns of the winding determine the resistance and current carrying capacity of the winding. When overloaded, a wire with a larger diameter can carry more current and reduce the heating of the winding. At the same time, the insulation structure of the winding should be designed to withstand the temperature that may rise when overloaded. The use of high-temperature resistant insulation materials and reasonable insulation thickness can prevent insulation breakdown accidents during overload. For example, the use of high-performance insulation materials such as Nomex insulation paper can improve the insulation performance of the winding at high temperatures and ensure the safe operation of the transformer, thereby indirectly improving the overload capacity of the transformer.
In addition, the overall structural layout of the transformer, such as the relative position of the core and the winding, the design of the oil tank (which may be a protective shell for dry-type transformers), etc., will also affect the heat dissipation effect and electromagnetic coupling efficiency. Reasonable layout can make the heat evenly distributed and dissipate quickly, while ensuring good electromagnetic coupling between the core and the winding when overloaded, and maintaining the output voltage stability of the transformer. Our company has in-depth research and rich experience in the structural design of amorphous alloy dry-type transformers. By optimizing various structural components and overall layout, the overload capacity of the transformer is improved, providing reliable equipment guarantee for the stable operation of the power system.
