The overload capacity of the dry transformer is related to the ambient temperature, the load before overload (initial load), the insulation heat dissipation of the transformer and the heating time constant, etc. If necessary, you can ask the manufacturer for the dry overload curve.
How to take advantage of its overload capacity?
The selection of transformer capacity can be appropriately reduced: full consideration of some steel rolling, welding and other equipment short-term impact of the possibility of overload - try to use the strong overload capacity of the dry transformer to reduce the transformer capacity; For some places with uneven load, such as residential areas for night lighting, cultural and entertainment facilities and shopping malls for air conditioning and daytime lighting, the overload capacity can be fully utilized to appropriately reduce the transformer capacity, so that the main operation time is full load or short overload.
