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 is 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 change voltage, current and impedance.

Classification

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

Working frequency

The core loss of the transformer is closely related to the frequency, so it should be planned and used according to the operating frequency, which is called the operating frequency.
