Transformer core
1, the core adopts high permeability and high-quality grain orientation cold rolled silicon steel, using 45° five-step overlap method to reduce no-load loss and no-load current.
2, the core design adopts simulation analysis method, accurate and effective calculation of vibration frequency and amplitude.
3, the iron core and the coil, the iron core and the clamp between the flexible connection. Through these measures, the noise level of the transformer is increased by 10-15dB compared to conventional products.
Application scenario
Dry transformers are widely used in local lighting, high-rise buildings, airports, terminals, CNC machinery and equipment and other places, simply said dry transformers refers to the iron core and winding is not impregnated in insulation oil transformer.
Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When air cooled naturally, the transformer can run continuously for a long time under the rated capacity. When forced air cooling, the transformer output capacity can be increased by 50%. Suitable for intermittent overload operation, or emergency overload operation; Due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operation state, so it should not be kept in continuous overload operation for a long time.
