The differences between three-phase dry type transformer and one phase transformer

Although three-phase dry-type transformers and single-phase transformers are different types of products, they have similar application functions that can be used to change voltage and current, safely dry-type and perform voltage regulation, and are still used in many fields. However, three-phase dry-type transformers and single-phase dry-type transformers are always different types of products. Their input and output power types are single-phase dry-type transformers that use the principle of electromagnetic induction to change the AC voltage. The primary coil, secondary coil, and magnetic core are its main components. It is also worth mentioning that single-phase dry-type transformers are different from three-phase dry-type transformers in terms of input and output power types. The input and output of the former are single-phase AC power, and only provide the same power to the load as the single-phase load.
 The input and output of the three-phase dry-type transformer are three-phase symmetrical AC power, which can provide two different types of power, three-phase power and single-phase power, and the three-phase dry-type transformer uses three independent windings, and different connection methods can be used. To input and output three-phase AC power.
In the application of transformers, single-phase dry-type transformers are more suitable for low-voltage power distribution with a relatively small load density because of their simple structure and small size. Three-phase dry-type transformers are different from single-phase dry-type transformers, and It is more complicated, so it is now widely used in printing and packaging, petrochemicals, schools, shopping centers, elevators, post and telecommunications and various industrial automation equipment to ensure the location of voltage. In addition, because the three-phase dry-type transformer with high service quality has the ability to eliminate common mode interference and other neutral wires in the power grid, it can effectively eliminate high-frequency pulse interference and noise coupled inside the transformer, and it can well adapt to various Complexity, application environment.
In short, the differences between three-phase dry-type transformers and unidirectional transformers are mainly reflected in the types of input and output power and application fields. At the same time, it can be seen from the above introduction that three-phase dry-type transformers and single-phase transformers have their own characteristics and Advantages, in order to make these transformers play a role in practical applications, please strictly follow reasonable operating methods. In summary, the main differences between three-phase dry-type transformers and unidirectional transformers are mainly reflected in the type and application field of output power.
