In addition, the transformer also has the following characteristics and advantages:
High efficiency: The efficiency is as high as 99%, and it can provide stable power output.
Safety isolation: As an isolation transformer, it can effectively isolate the circuit and improve the safety of electricity use.
Wide range of application: Suitable for a variety of electrical equipment and industrial applications, including machine tools, mechanical equipment, medical equipment, etc.
Strong environmental adaptability: Although it is mainly designed for indoor use, its dry cooling and sealed moisture-proof make it have a certain degree of outdoor adaptability
Cooling methods of dry-type transformers
There are two main cooling methods for dry-type transformers: natural air cooling and forced air cooling. Under natural air cooling, the transformer can operate continuously at rated capacity for a long time. When forced air cooling is used, the output capacity of the transformer can be increased by 50%, which is very suitable for intermittent overload or emergency overload operation. However, it should be noted that the load loss and impedance voltage increase during overload operation are large, which is in a non-economic operation state, so it is not recommended to operate overload continuously for a long time.
