How to solve the performance bottleneck of Amorphous Alloy Dry Type Transformer under high load?

In modern power systems, Amorphous Alloy Dry Type Transformer is favored for its high energy efficiency, environmental performance and excellent short-circuit resistance. However, under high-load operating conditions, these transformers may face performance bottlenecks such as excessive temperature rise and reduced efficiency.
1. Understanding the characteristics and challenges of Amorphous Alloy Dry Type Transformer
Amorphous Alloy Dry Type Transformer uses ultra-thin magnetic materials as the core, which has the advantages of low loss, high resistivity and environmentally friendly manufacturing. However, this material also has problems such as thin thickness, rough surface and low core filling factor, which may cause excessive temperature rise and reduced efficiency of the transformer under high load. In addition, the heat dissipation capacity of dry-type transformers is limited, and it is easy to affect performance due to heat accumulation when overloaded.
2. Improve heat dissipation performance and optimize temperature rise management
For the temperature rise problem in high-load operation, the following measures can be taken to improve the heat dissipation performance:
Increase heat dissipation channel design: Enhance the heat dissipation effect by optimizing the air circulation path inside the transformer. For example, the axial ventilation channel design can effectively reduce the core temperature.
Introducing a fan cooling system: Adding a built-in fan to the transformer to improve the heat dissipation efficiency by actively dissipating heat. Studies have shown that the fan cooling system can increase the load capacity of the transformer by 1.33 times.
Improving insulation materials: Using high-temperature resistant epoxy resin insulation materials can improve the thermal stability of the transformer and reduce insulation aging caused by temperature rise.
3. Optimizing design to improve efficiency and reliability
In order to further improve the efficiency and reliability of the Amorphous Alloy Dry Type Transformer, the following measures can be taken:
Adopting a stepped core structure: By using a stepped core instead of a traditional smooth core, eddy current losses can be reduced and overall efficiency can be improved.
Optimizing winding design: Using high-quality wires and optimized winding structures can reduce copper losses and iron losses, thereby improving the operating efficiency of the transformer.
Enhancing short-circuit resistance: By rationally designing the windings and strengthening the thickness of the insulation layer, the short-circuit resistance of the transformer can be significantly improved to ensure stable operation under high load.
4. Implement regular maintenance and monitoring
In order to extend the service life of amorphous alloy dry-type transformers and ensure their stable operation under high load, regular maintenance and monitoring are essential:
Regular inspection and testing: By regularly detecting parameters such as temperature rise, noise and insulation resistance of the transformer, potential problems can be discovered in time and measures can be taken.
Environmental adaptability management: According to the different installation environments, adjust the operating parameters of the transformer, such as adding cooling equipment or adjusting load distribution in high temperature environments.
