Overload capacity of dry-type transformers

The overload capacity of dry-type transformers is related to the ambient temperature, the load condition before overload (initial load), the insulation and heat dissipation of the transformer, and the heating time constant. If necessary, the overload curve of the dry-type transformer can be obtained from the manufacturer.
How to utilize its overload capacity? The author proposes two points for reference:
⑴ When choosing to calculate transformer capacity, it is advisable to reduce it appropriately: fully consider the possibility of short-term impact overload of certain equipment such as steel rolling and welding - try to use the strong overload capacity of dry-type transformers to reduce transformer capacity; For places with uneven loads, such as residential areas with nighttime lighting, cultural and entertainment facilities, and shopping malls with air conditioning and daytime lighting, their overload capacity can be fully utilized by appropriately reducing the transformer capacity to keep their main operating time at full load or short-term overload.
