INTRODUCTION
Dry-type transformers refer to the serials of transformers whose core and windings
Are not immersed in the insulating oil .Cooling ways are divided into natural air
Cooling (AN) and forced air cooling (AF).
When designed with natural air cooling, transformer can be long-term continuously operated at the rated capacity.When designed with forced air cooling, transformer output capacity can be increased.Dry-type transformers are suitable for intermittent overload operation, accident or
Emergency overload operation;
Due to overload loss and impedance voltage increase largely , the transformer is not in an economical operating state, so it should not be run at continuous overload state for a long-term.
APPLICATION
High-rise buildings, commercial centers, city squares, hospitals, schools, airports, railway stations, port terminals, subway, power plants, oil field, chemicals, tunnels and other places.
