The differences between dry-type transformers and oil-immersed transformers.

 

 

The differences between dry-type transformers and oil-immersed transformers lie in their structure, working principles, and applications.

 

 

Dry-type transformers use dry solid insulation materials such as paperboard and resin inside, eliminating the need for oil immersion. On the other hand, oil-immersed transformers have their windings immersed in insulating oil to enhance insulation performance.

 

In terms of maintenance, dry-type transformers do not require regular oil changes, making maintenance relatively simple and suitable for environments with strict fire safety requirements like offices and hospitals. Oil-immersed transformers, on the other hand, need periodic inspection and oil replacement, leading to higher maintenance costs, but they are advantageous for large industrial facilities.

 

 

Safety-wise, dry-type transformers have an edge as they do not use insulating oil, reducing the risk of leaks or fires, making them suitable for high safety requirement locations. In contrast, oil-immersed transformers are typically used in larger industrial settings, such as substations, but require careful consideration of maintenance costs and safety.

 

Understanding these differences can help in selecting the appropriate transformer type based on specific needs and application environments, ensuring safe and stable operation of equipment. When choosing a transformer, factors such as technical specifications, performance, maintenance costs, safety, and environmental requirements should all be taken into account to achieve optimal power transmission efficiency.
