main parts of transformer | core | conservator | breeder | buckle relay | Silica gel

Name of the main parts of the transformer:

1.core, 2.primary winding, 3.secondary winding, 4.conservator, 5.breather, 6,insulator, 7.insulation oil, 8.Bukhlaj relay, 9.tank, 10.bushing, 11.vent pipe, 12.earthing point, 13.transformer oil, 14.radiator tube

Some information about the core, conservator, breeder, buckle relay, and Silica gel.


The frame on which the windings are spread is called the core The magnetic flux generated in the primary as a result of the use of steel cores can be effortlessly associated with the secondary. 

Core use usually causes eddy current and hysteresis loss in the core Which is known as core loss The thickness of the core is 50 cycles/sec.


Transformer oil increases in volume when heated decreases in volume when cooled. As the volume increases, the oil wants to come out of the tank


So a small drum-shaped tank is placed on the top of the tank by connecting it to the tank through a pipe. It is called Conservator.

 As the volume of oil increases, it accumulates in the conservator through the oil pipe When it cools down again when the volume of oil decreases, the oil from the conservator returns to the tank 


 Expansion of oil compression causes air from outside to enter the transformer tank and exit.

When air enters the tank, the water vapor is dried by absorbing water vapor from the air.

 The part of the transformer through which air enters and exits and which releases and evaporates water vapor during entry is called a breather.

Bukhlaj relay: 

The Bukhlaj relay is one of the protection systems of high-rating transformers. Bukhlaj relay is connected between the transformer tank and the conservator connecting the pipe.

The relay has a system that automatically shuts off if gas accumulates in the transformer for any reason. 

When there is too much pressure on the gas, the glass breaks and the gas comes out

Silica gel:

Silica gel is placed on a wire mesh in a breathalyzer which absorbs the water particles of a granular chemical and dries the air.

As a result, water cannot mix with the oil inside the transformer tank As a result, sediments or sediments do not accumulate in the oil and when they are used for a long time, they turn brown or light gray in color. These are replaced with new transparent silica gel.
