Description

Technical Field

[0001] The utility model relates to the technical field of transformer bases, in particular to a dry-type transformer base. Background Art

[0002] With economic development, dry-type transformers have achieved rapid development around the world, especially in distribution transformers, where the proportion of dry-type transformers is increasing. Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and other places. Simply put, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil. The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). With natural air cooling, the transformer can operate continuously at rated capacity for a long time. With forced air cooling, the transformer output capacity can be increased by 50%. Dry-type transformers have the characteristics of high mechanical strength, strong short-circuit resistance, low partial discharge, good thermal stability, high reliability and long service life.
