To understand transformers simply, start with dry-type transformers. Dry-type transformers are widely used in places such as local lighting, high-rise buildings, airports, docks, and CNC machinery. In short, dry-type transformers refer to transformers where the core and winding are not immersed in insulating oil.
Cooling methods include Natural Air Cooling (AN) and Forced Air Cooling (AF). During natural air cooling, transformers can operate continuously at full rated capacity for extended periods. With forced air cooling, the transformer's output capacity can be increased by 50%. Suitable for intermittent overload operation or emergency overload operation; however, due to the significant increase in load losses and impedance voltage during overload, it is not economically viable to operate it continuously under overload conditions. Key features of dry-type transformers:
Due to the advantages of dry-type transformers, such as strong short-circuit resistance, low maintenance workload, high operating efficiency, compact size, and low noise, they are commonly used in places with high performance requirements like fire prevention and explosion-proof.
Safety, fire-resistant, pollution-free, ready for direct operation at load centers.
2. Utilizes cutting-edge domestic technology, featuring high mechanical strength, excellent short-circuit resistance, minimal partial discharge, good thermal stability, high reliability, and long service life; 3. Low loss, low noise, significant energy-saving effect, and maintenance-free.
4. Excellent heat dissipation and overload capacity; can increase capacity when forced air-cooled; 5. Good moisture resistance, suitable for operation in high humidity and other harsh environments.
6. The kilovolt transformers are equipped with a complete temperature detection and protection system. Utilizing an intelligent signal temperature control system, it can automatically detect and display the working temperature of each phase winding, automatically start and stop the fan, and is equipped with alarm and trip functions.
7. Compact, lightweight, low space requirement, and low installation costs.
