Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dry-type transformers, in particular to a dry-type transformer capable of reducing swing impact. Background Art
[0002] Transformers are widely used in daily life. Transformers are static electrical appliances that use the principle of electromagnetic induction to convert one level of voltage and current into another level of voltage and current of the same frequency between two or more coils, and transmit electrical energy. Transformers are divided into oil-immersed transformers, fully sealed transformers, combined transformers and dry-type transformers. Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, a dry-type transformer refers to a transformer whose core and winding components are not immersed in insulating oil. It is easy to produce continuous shaking during transportation, installation or when the wind outside is strong, which will cause the fixed part of the dry-type transformer to loosen. In addition, the dry-type transformer needs to be stable and static during operation. Continuous vibration can easily cause working failures of the dry-type transformer and affect the stability of the line. Utility Model Content
