What is the purpose of tank in transformer?

Function of Conservator Tank of a Transformer When transformer is loaded and when ambient temperature rises, the volume of oil inside transformer increases. A conservator tank of transformer provides adequate space to this expanded transformer oil. It also acts as a reservoir for transformer insulating oil.

Why is a conservator tank cylindrical?

The shape of the conservator tank in the transformer is cylindrical where both the ends of the oil container are closed. This arrangement ensures that transformer oil does not flow into a silica gel breather even at the maximum operating level.

Why transformer oil is filled in the tank?

The Oil (known as Transformer Oil, Ref – IS 335) serves the purpose of providing insulation to the transformer winding. It also helps in the cooling of the transformer.

Why tubes are used in transformer?

These Cooling Tubes provide better and effective cooling of transformer oil by increasing the surface area of tank to the atmosphere.

What is the function of conservator tank?

The Conservator Tank is simply a tank that is used to provide enough space for the oil in the transformer to spread after heating. It is placed on the roof of the transformer. The main function of the Conservator Tank is that once the transformer is loaded, its temperature rises, and the oil in it starts spreading.

Why is silica gel used in transformers?

The purpose of these silica gel breathers is to absorb the moisture in the air sucked in by the transformer during the breathing process. Silica gel in the breather will be blue when installed and they turn to pink color when they absorb moisture which indicates the crystals should be replaced.

What is leakage flux in transformer?

Leakage flux is defined as the magnetic flux which does not follow the particularly intended path in a magnetic circuit. When a current is passed through a solenoid, magnetic flux is produced by it.

What is the use of the tank with tubes?

What is the usage of the tanks with tubes? Explanation: Temperature rise in transformers is calculated with plain walled tanks. If the limits is exceeded then the plain walled tank is replaced by tank with tubes.

What is the use of cooling tubes?

Cooling tubes are an efficient way to cool a building using natural convection and thermal mass principles. They require no pumps or fans, and are completely passive (no moving parts).

What is difference between bushing and insulator?

is that bushing is (mechanical engineering) a type of bearing, a cylindrical lining designed to reduce friction and wear inside a hole, often used as a casing for a shaft, pin or hinge while insulator is a substance that does not transmit heat (thermal insulator”), sound (”acoustic insulator”) or electricity (” …

How does a cylindrical tank work in a transformer?

A cylindrical tank accessory plays a key role in the transformer. It is arranged over the main tank’s roof so that sufficient space can be provided to expand the transformer oil. Once the temperature increases, then the oil volume can also be increased. So it acts as a reservoir for expanded oil in the transformer oil.

What is the function of conservator tank in a transformer?

Function of Conservator Tank of a Transformer. When transformer is loaded and when ambient temperature rises, the volume of oil inside transformer increases. A conservator tank of transformer provides adequate space to this expanded transformer oil.

What happens to the oil in a transformer when it cools?

As the load on the transformer decreases, the transformer cools down and shuts down. The oil in the conservator tank seems to shrink after the atmosphere cools down. The main cause of oil shrinkage is the outside air that enters the tank with the help of silicate gel.

What are the different types of transformer accessories?

But to provide long service life to the transformer, there are different kinds of accessories are used by connecting to it. The transformer accessories are breather, conservator tank (cylindrical tank), and explosion vent. A cylindrical tank accessory plays a key role in the transformer.
