Composition of transformer

A transformer is an electrical device used to change the magnitude of an alternating current voltage. Its main components include:

1.Core (magnetic core) : Usually made of silicon steel sheets or ferrite materials, it is used to concentrate and conduct magnetic fields, improving the efficiency of transformers.

2.Coil: includes a main coil (generally an input coil) and a secondary coil (generally an output coil). The main coil and the secondary coil are wound on two sections of the iron core respectively, and the voltage is changed by electromagnetic induction.

3.Insulation material: Used to insulate coils and other components to prevent current short circuits or insulation failures.

4.Cooling system: Usually oil cooling or wind cooling system is used to dissipate heat and keep the transformer operating within a safe temperature range.

5.Winding terminals: Used to connect input and output power supplies and external circuits.

6.Auxiliary equipment: including temperature sensors, protection devices (such as overcurrent protection, overvoltage protection, etc.), oil level indicators, etc., used to monitor and protect the normal operation of the transformer.

These components work together to enable the transformer to achieve voltage transformation and power transmission.
