Description

Technical Field

[0001] The utility model relates to the technical field of dry-type transformers, in particular to a dry-type transformer which is convenient for dust removal. Background Art

[0002] Dry-type transformer is the abbreviation of dry-type power transformer, which refers to a dry-type transformer whose core and winding are not impregnated with oil (or other liquids). Its core is made of stacked silicon steel sheets. The magnetic circuit system adopts the principle of electromagnetic saturation and uses the air gap magnetic field to transfer energy. Dry-type transformers rely on air convection for cooling. They are generally used for small-capacity transformers such as local lighting and electronic circuits. In the power system, steam turbine transformers, boiler transformers, ash removal transformers, dust removal transformers, desulfurization transformers, etc. are generally dry transformers.

[0003] According to a disclosed dry-type transformer that is easy to remove dust (publication number: CN215868898U), in the above application, an exhaust fan can be used to continuously extract the air in the casing, so that the air in the casing is in a flowing state, thereby preventing dust from being adsorbed onto the transformer under the electrostatic attraction of the transformer.

[0004] However, in actual use, the above equipment prevents dust from collecting on the surface of the transformer through the setting of the exhaust fan, but dust will enter the inside of the transformer. The dust adheres to the inside and causes damage to the transformer. The dust inside the transformer cannot be removed and the transformer is cooled when the dust is blown away, thereby reducing the service life of the transformer. In view of this, we propose a dry transformer that is easy to remove dust. Utility Model Content
