Understand the role of transformer skeleton in daily life

The transformer skeleton is used to change the AC voltage setting, consisting of an iron core and coil wires. It can not only change the AC voltage, but also the impedance, changing the current without exceeding the design power.

In different environments, transformer skeletons are used for different purposes, such as:

In electronic amplifier circuits, in order to minimize the transmission energy consumption between two amplifiers, impedance matching and connection to the transformer skeleton are necessary to change the impedance.

In the AC voltage regulator, the number of turns of the output coil is changed in real time to achieve the purpose of adjusting the output voltage.

3. For remote input power lines, in order to reduce line losses, it is necessary to first increase the power of the power plant to tens of thousands of volts (such as 11KV), and then reduce it (such as 220V) after reaching the destination.

Sometimes, in an environment that requires different voltages, transformers can be made into multi winding or intermediate tap type. This will generate various voltages.

When welding, a large current (tens to hundreds of amperes) is required between the electrode and the welded part, but the voltage is very small (a few volts). A welding machine is a transformer that converts high voltage (such as 220V) into low voltage. Generate a large current at the output terminal without changing the power.

Transformer accessories generally include: iron core, winding, oil tank, oil storage tank, insulation sleeve, tap changer, cooling system, explosion-proof pipe, gas relay.

Each one is very important and indispensable.
