Dry-type transformers are widely used in power systems due to their excellent fire safety, environmental friendliness, and maintenance-free operation. However, their thermal performance is a major concern, and their temperature rise and heat dissipation design are critical to their safe and efficient operation.

The temperature rise of a dry-type transformer refers to the increase in temperature of its windings and core during operation. The temperature rise is affected by factors such as load, ambient temperature, and ventilation conditions. To ensure the safe operation of the transformer, it is essential to design its temperature rise within the allowable limits specified by the relevant standards.

The heat dissipation design of dry-type transformers is also crucial. The heat generated by the transformer needs to be dissipated effectively to prevent its temperature from exceeding the allowable limits. This is achieved through various cooling methods, such as natural air cooling, forced air cooling, and water cooling. The choice of cooling method depends on factors such as the transformer's size, operating conditions, and cooling requirements.

In addition to cooling methods, other factors that affect the heat dissipation of dry-type transformers include the material and thickness of the insulation, the size and arrangement of the windings, and the use of auxiliary cooling devices such as fans and heat exchangers. Proper design and selection of these factors are essential for ensuring the safe and efficient operation of the transformer.

In summary, the temperature rise and heat dissipation design of dry-type transformers are critical factors that affect their safe and efficient operation. Proper design and selection of these factors are essential for ensuring that the transformer operates within the allowable temperature limits and has sufficient heat dissipation capability.
