Description

Technical Field

[0001] The utility model relates to the technical field of dry-type transformers, in particular to a high-efficiency heat dissipation transformer fan. Background Art

[0002] A dry-type transformer is a type of electrical equipment, mainly used for voltage conversion. Its characteristic is that the core and winding are not immersed in insulating oil, but directly exposed to the air. This design makes dry-type transformers more environmentally friendly, fireproof, and easy to maintain compared to oil-immersed transformers, and is suitable for installation in public places. When the dry-type transformer is in use, the dry-type transformer is generally connected to an external cooling fan. When the temperature of the dry-type transformer rises to a certain level, the airflow contacts the dry-type transformer to dissipate heat.
