What is transformer and its types

You must have heard the name of the transformer, but if you want to know about the transformer in detail, then in this post today we will know What is transformer and its types and How does Transformer work? Its benefits?

Transformers were invented almost 200 years ago and electrical-related tasks became easier. Transformers were also gradually made into many types, they were used in various works. If any electricity is to be controlled, then we can use transformer and remove the malfunction.Through this article, you will provide detailed information about the transformer and will also explain who discovered this electric machine and for what purposes human civilization uses it today.

What is transformer

An electric device that moves through electricity. It serves to transmit electric energy from one place to another. When the Electrical Circuit recieves the electrical power of the source, it is called Primary Winding and the second circuit which delivers the electric energy is called Secondary Winding.

It is used to reduce or decrease the frequency of AC supply without changing it. They are also used in DC machines, which are run by AC Supply. DC devices can run much less power than AC devices.

When an audio amplifier works from a 12 volt DC using a transformer it is first converted from AC volt to 220 volt to 12 volt and then converted from AC to DC with the help of a rectifier. This is how transformers are used.

Its use is increasing day by day. Today we use transformers from a large station to a small house as well. Their shape has also changed according to the requirement of the people so that no problem arises in its maintenance.What is transformer and its types

Transformer invented

Transformers have an important place in inventions related to electricity. If the transformer is not there, many electrical appliances are damaged. Electrical transformers were invented in 1831 by Michael Faraday in Britain. In this way Britain brought information about transformers to the people.

Types of transformers

The transformer is divided into several types. They are also divided on the basis of their use and size. We have classified the types according to its different grounds, which are as follows: –

A. Depending on the structure of the core

1. Shell Type Transformer
It is made by adding leaves of the letters E and I of the English alphabet. There are three libs in it, two windings are done on one lib and winding is done on the middle lib whose area is double than the two sides. Low voltage winding is done near the core and high winding is done over low voltage winding. There are two ways of magnetic flux used in running low voltage machines.

2. core type transformer
The shape of this transformer is of L type which is made by insulating silicon steel leaves. It consists of 4 Libs. Two Libs are face to face and there is only one way for magnetic flux. It is used for high voltage.

B. Based on output voltage

1. Step up transformer
It provides more output voltage by increasing the input voltage. There are more coils wrapped on the secondary winding than the primary winding. It is used in stabilizers, inverters etc. It is used in power plant to connect with grid

2. step-down transformer
Under this, the input voltage is reduced to give a lower output voltage. It is powered by DC supply, is used in many devices because it converts AC to DC and supplies DC electricity to electrical machines, which is why most people use it.

C. Depending on the number of electrical phase

1.Single Phase Transformer
This transformer is a transformer operating on AC supply, in which the voltage of single phase can be reduced or increased. It has two windings, primary and secondary windings.

Single phase power supply is done in primary winding and in second winding, single phase electrical supply is done as step down or step up.

2. Three Phase Transformer
It has 3 primary and 3 second windings. They are used for transfer using KVA steps of 66, 110, 440. Where there is a distribution system, three phase transformers are used. Nowadays use of three phase transformers has become very common.

D. Based on Core Medium

1. Air Core Transformer
Both primary and secondary bindings are employed in it. It has much more flex generated than iron-core.

2. Iron Core Transformer
Primary and secondary bindings are also put in this but a lot of iron strip is put in it, which produces a Perfect Linkage. Its functionality is much more than a core type transformer. Working principle of transformer It works on the principle of mutual induction.

It has two windings. One winding acts as an electromagnetic force and the other winding acts as a magnetic field. When AC is supplied in the first winding, a magnetic field or magnetic field is formed around it, which we call electro motive force.

After this the second winding comes inside the magnetic field, then the electron activity in it starts and we get AC supply at one end of the coil. But the output supply of the transformer depends on its input supply, which is how the transformer functions.What is transformer and its types

Part of the transformer

Input Connection
It is also called Primary Side because the electrical power in it is connected to this point.

Output Connection
This is called a secondary site because the incoming electric power can be increased or decreased according to the load requirement from where the electrical power is sent.

The transformer has two winding Primary Winding and second Secondary Winding Primary winding The binding on which the input is supplied is called primary winding and the winding on which the output wires are put and this binding gives the transformer an out put. We do.

It is used as a control path, used to generate magnetic flux. Transform is made in Core Form and Shelle Form The transformer in which the winding is applied around the core is called the course form and the transformer in which the core is applied around the winding is called Shelle Form.

Its core is made by silicon steel leaves. The width of these leaves is between 0.35 mm to 0.75 mm. These leaves are interconnected with the help of varnish. Transformer These leaves are mainly I, L, E of the English alphabet. Cut into the shape of etc.

Its coil is coupled to the input and output wires of the transformer, which performs the function of input and output. The wires that hold the two together are called Coil.

Oil Level Indicator
Under this, oil is filled in the converter tank, but it is fitted 1 meter to measure which ensures the amount of oil to be filled in the tank. It is mounted on the tank itself, it is called oil level indicator.

Insulated Sheet
This is the important seat of the transformer. It is placed between the primary winding and the secondary winding so that no short circuit of any kind is generated. This does not cause any damage to the winding. Without this the transformer is very difficult to operate for a long time.

Conservator Tank
As you all know that there are many types of transformers as well, different components are installed based on them. The conservator tank is fitted in a three phase transformer. Oil is poured inside it. Its function is to keep the transformer cool, so that the heat inside the transformer can be controlled. This is a very important part of the three phase transformer.

Oil Filling Pipe
There is an oil tank inside the transformer in which a pipe is placed to fill the oil. Through this pipe oil is filled in the tank but it is only applied in large transformers, this oil is used to keep the transformer cool.

Radiator Fan
Long-term use of the transformer causes it to heat up so that there are chances of damage to the primary and secondary windings, hence a radiator fan is also installed. The function of which is to cool the transformer. Just as radiators are used to keep the engine cool in vehicles, a radiator is also installed in transformers.What is transformer and its types

Functions of transformer

● Its best function is to lower or lower the voltage level.
● We can easily do this from one circuit to another where we have to increase or decrease the voltage level.
● Where power distribution is done, three-phase transform is used, it is used the most.
● It is also used to isolate circuits from other, these transformers are called isolation transformers.
● Their function is similar to the wrapping of Primary Winding and Secondary Winding. It is also used to maintain electro magnetic field.What is transformer and its types
