Manufacturing principle of marine transformer

In the generator, whether the coil moves through the magnetic field or the magnetic field moves through the fixed coil, an electric potential can be induced in the coil. In these two conditions, the value of the magnetic flux remains unchanged, but the amount of magnetic flux that intersects the coil is different. Change, this is the principle of mutual induction. Marine transformer is a device that uses electromagnetic mutual induction to transform voltage, current and impedance.

Classification

Classification by cooling method: dry-type (self-cooling) transformer, oil-immersed (self-cooling) transformer, fluoride (evaporative cooling) transformer.

Classified by moisture-proof method: open transformer, potting transformer, sealed transformer.

Classification by core or coil structure: core transformers (insert core, C-type core, ferrite core), shell-type transformers (insert core, C-type core, ferrite core), Toroidal transformers, metal foil transformers.

According to the number of power supply phases: single-phase transformers, 3-phase transformers, multi-phase transformers.

Classification by use: power transformers, voltage regulating transformers, audio transformers, intermediate frequency transformers, high frequency transformers, pulse transformers.

Characteristics of power transformers

working frequency

The core loss of the transformer has a great relationship with the frequency, so it should be designed and used according to the operating frequency, which is called the operating frequency.
