Oil Filtration Plant |
Our filtration plants purify and upgrade transformer oil to comply with standard specifications. These plants can be designed as per customer’s specifications and are also available in varying capacities covering a whole range of applications in low, high and extra high voltage equipments. They perform the following functions: |
| |
Removal of suspended impurities such as dust, rust, scales, colloidal carbon oxidation sludge etc. up to < 1 micron. |
| |
Degassing and Dehydration of Transformer Oil with vacuum
Circulation of heated Oil and Filling of treated oil in Transformer tank
Prevention of acid formation by evaporation and adsorption method |

Transformer Oil Filtration Plant |
Our oil filtration plants are used to remove impurities from transformer and switchgear oil such as moisture, dirt, air and other gases. This is a `low temperature and high vacuum` principle based equipment as per the International Standards 6034 (1989) and its latest revision. We manufacture plants of variable capacities of 600 to 10000 lph which can be customized to special capacities if required by the clients. This plant takes the impure oil into the system through the inlet ball valve and then pumps it through by a positive displacement pump. A filter prior to this removes solid particles up to 1mm size and magnetic particles. After heating the oil up to 60°c it passes through the cartridge filters, where particles up to 5 microns are filtered. A specially designed vacuum chamber removes moisture, air and all the gases with the help of vacuum. The oil falls by way of gravity over the media inside forming a thin film of oil, exposing a larger surface area. The dissolved moisture and gases are evacuated and the oil is ready. |

Mobile Oil Filtration Plant |
During
its operation of generating, transmitting and distributing power
transformers give out heat which is absorbed by insulating oils. This
oil has a tendency to absorb moisture from windings which leads to
gradual deterioration of dielectric strength. Our filtration systems
provide economical and efficient methods of purifying this lubricant.

Components
of Plant |
The filter unit is a coarse strainer with a wire mesh filter element for retaining solid particles and a powerful magnet for retaining magnetic particles. It has round filter paper discs held under spring compression. Specially designed heaters with low watt density heat the auxiliary heating oil, which in turn heats the transformer oil maintaining a temperature of 70-80 C. The cylindrical external pressure vessel is fitted with various shallow drip trays and a specially designed spray pipe to increase surface area. The vapor from dehydration chamber is condensed in a condensate receiver of welded M. S. construction. There are feed and delivery pump of rotary gear type coupled directly with motors. Water Separator Collect the water produced. A centralized control panel has indicators for all electrical devices. |

Vacuum Impregnation Plant |
The
Vacuum Impregnation Plants can be designed as per clients’
requirements and is provided with the following specifications. |
| |
IMPREGNATION
CYCLE |
| |
It
is designed as per the schematic diagram attached and is used for
varnish impregnation to be carried out in following steps: |
-
Pre-heating
the jobs in either Impregnation Chamber or Oven.
-
Evacuation
of Impregnation Chamber (after putting the jobs) to make the voids
in the jobs clear and drying of jobs for specific time &
required temperature / vacuum.
-
Induction
of impregnant (Varnish) in the Impregnation Chamber from impregnant
Tank to submerge the jobs in it.
-
Pressurize
the Impregnation Chamber with dry air or nitrogen to fill the voids
with impregnant.
-
Return
the varnish to impregnant Tank.
-
Evacuate
the Impregnation Chamber and cure the jobs either in impregnation
Chamber or in Oven for specific time.

Vacuum Drying Autoclave |
Our
Vacuum Drying Autoclaves are designed and manufactured as per the
specifications provided by our clients. We have the capability to
manufacture high performance autoclaves which increase the efficiency
and performance of any plant. This equipment comprises a vacuum
autoclave in which a cylinder containing a piston is situated at one
end and can be closed at the end by a hollow piston containing a
condenser casing. The cylinder is evacuated through a port and the
piston is lowered to close the port immediately an injection valve is
opened to fill the cylinder with an impregnating substance. When the
injection valve is shut the piston slowly presses the impregnant out
through the neck of the condenser casing. The pressure is increased
till the ejection valve opens. A blast of gas cleans the cylinder to
remove any remaining impregnant. |
