What are the components of a transformer?

What are the components of a transformer?

The transformer components are mainly composed of iron cores and coils, as well as oil tanks, oil conservators, insulation sleeves, and tapping heads.

What is the use of transformer oil?

The function of transformer oil is:

(1) Insulation effect

(2) Heat dissipation effect

(3) Eliminating arc effects

What is an autotransformer?

An autotransformer has only one set of coils, and the secondary coil is tapped out from the primary coil. Its electrical energy is transmitted not only through electromagnetic induction, but also through electricity. This type of transformer has fewer silicon steel sheets and copper wires than ordinary transformers and is commonly used for voltage regulation.

How is the voltage regulator regulated?

The structure of the voltage regulator is the same as that of an autotransformer, except that the iron core is made into a circular coil and wound around the circular iron core.

The secondary coil tap uses a sliding brush contact to make the contact slide in a circular pattern along the surface of the coil, achieving a smooth voltage regulation effect.

8. What is the current relationship between the primary and secondary coils of a transformer?

When a transformer operates with a load, the change in secondary coil current will cause a corresponding change in primary coil current. According to the principle of magnetic potential balance, the current of the primary and secondary coils is inversely proportional to the number of turns in the coil. The current on the side with more turns is smaller, while the current on the side with less turns is larger.

It can be expressed as follows: primary coil current/secondary coil current=number of turns in the secondary coil/number of turns in the primary coil.
