Dry-type transformers are widely used in local lighting, high-rise buildings, airports, terminals, CNC machinery and other places. Simply speaking, dry-type transformers are transformers whose cores and windings are not immersed in insulating oil.
Dry-type transformers are widely used in local lighting, high-rise buildings, airports, terminals, CNC machinery and other places. Simply speaking, dry-type transformers are transformers whose cores and windings are not immersed in insulating oil. The cooling method is divided into natural air cooling (AN) and forced air cooling (AF). Under natural air cooling, the transformer can continuously run for a long time at the rated capacity. With forced air cooling, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation or emergency accident overload operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operating state, so it should not be subjected to long-term continuous overload operation.
Dry-type transformers are mainly divided into three types: open type, closed type and cast type.
The safe operation of dry-type transformers and their service life depend largely on the safety and reliability of the transformer winding insulation.
