Dry-type transformer manufacturer shares its cooling method

Dry-type transformer is a very efficient electrical equipment and has been widely used. So do you know about its cooling method? Below, our dry-type transformer manufacturer shares its cooling method.

The cooling method of a dry-type transformer is an important factor in determining its performance and service life. The cooling methods of dry-type transformers are mainly divided into natural air cooling (AN) and forced air cooling (AF).

Natural air cooling refers to the use of natural convection to remove heat through the flow of air around the transformer without external driving force. This cooling method relies primarily on air flow and ambient temperature around the transformer. Under natural air cooling, the transformer can operate continuously for a long time at rated capacity and maintain good cooling effect even when the ambient temperature is high.

Forced air cooling refers to the use of fans or other mechanical devices to accelerate the flow of air around the transformer through forced convection, thereby taking away heat faster. This cooling method can maintain a good cooling effect when the transformer is operating at full load, and can operate continuously for a long time when the output capacity of the transformer is increased by 50%.

The choice of cooling method for dry-type transformers depends on its use environment and operating conditions. In some places where long-term continuous operation is required or where the transformer output capacity needs to be increased, such as high-rise buildings, airports, docks, etc., forced air cooling is usually chosen. In some places with temporary or intermittent loads, such as local lighting, CNC mechanical equipment, etc., you can choose natural air cooling.

In short, the cooling method of dry-type transformers needs to be selected according to the specific use environment and operating conditions. Correct cooling method can ensure the normal operation of the transformer and improve its service life and reliability.
