Differences between Three Phase Transformers and Single Phase Transformers
Although three-phase transformers and single-phase transformers are different types of transformer products, they both have very similar functions and can play a role in changing voltage and current, safe isolation and voltage regulation, and play a role in many professional fields. is a very crucial role. However, three-phase transformers and single-phase transformers are always different types of transformers, and there are distinct differences between them:
1. Input and output power supply type
A single-phase transformer is a device that uses the principle of electromagnetic induction to achieve the purpose of changing the AC voltage, in which the primary coil, the secondary coil and the magnetic core are all its main components. At the same time, it is worth mentioning that the single-phase transformer is different from the three-phase transformer in terms of the input and output power types. The former input and output are both single-phase AC power and only need to provide single-phase power for single-phase loads. . The input and output of the three-phase transformer are three-phase symmetrical alternating current, which can provide two different types of power supply, three-phase power supply and single-phase power supply. And the high-end three-phase transformer uses three independent windings, which can input and output three-phase AC power with different connection methods.
2. Application areas
Because the single-phase transformer is simple in structure and small in size, it is more suitable for use in low-voltage distribution networks with relatively small load density. Three-phase transformers are widely used in printing and packaging, petrochemicals, schools, shopping malls, elevators, post and telecommunications, and various industrial automation equipment because their structure is different and more complex than single-phase transformers. the occasion. Moreover, because the three-phase transformer with high service quality has the ability to relieve the common mode interference of the power grid and the troubles of other neutral lines, it can effectively avoid the high-frequency pulse interference and noise coupled by the transformer, and can be well adapted to various complex Application Environment.
In summary, the difference between a three-phase transformer and a one-way transformer is mainly reflected in the type of input and output power supply and application fields. At the same time, it can be seen from the above introduction that three-phase transformers and single-phase transformers have their own characteristics and advantages. In addition, in order for these transformers to function in practical application, a reasonable operation method must be strictly followed.
