Oil
Inlet
Gear
Pump |
|
A
positive
displacement
pump
sucks
the oil
from the
transformer
/
storage
tank and
delivers
it to
the
conditioning
machine.
A built
in
relief
valve
takes
care of
any
excessive
pressure
rise. |
| |
|
Heating
System |
|
The oil
heater
heats
the
transformer
oil to
the
required
set
temperature.
It is
provided
with
electrical
resistance
elements
enclosed
in MS
tubes
separating
them
from
oil.
Digital
temperature
controllers
are
provided
for
controlling
the
temperature.
Further
a
pre-set
safety
thermostat
is
provided
to
prevent
accidental
rise in
pressure
over the
desired
level.
Suitable
baffles
in the
heater
vessel
prevent
hotspots. |

Filters |
|
Filtering
is
achieved
by means
of
Non-hygroscopic,
high
efficiency
imported
filter
cartridges.
The
filter
medium
is
progressively
denser
in the
direction
of flow.
This
unique
feature
ensures
large
dust
holding
capacity.
The
filter
housing
is
designed
for easy
replacement
of
choked
cartridges
and the
compound
gauge on
the
housing
indicates
the
differential
pressure
developed
due to
the
condition
of the
cartridges. |

|
Degassing
System |
|
The
optimally
designed
(single/double
stage)
chamber
consists
of
columns
of
raschig
rings to
ensure
maximum
exposure
of oil
to high
vacuum,
which
causes
moisture
and
gases to
evaporate.
Suitable
vacuum
pumping
system
of
sufficient
throughput
capacity
(rotary,
roots
vacuum
pump)
ensures
low
vacuum.
The flow
of oil
is
indicated
through
the
sight
glass
provided
on the
chamber. |

|
Outlet
Glandless
Centrifugal
Pump |
|
A
centrifugal
glandless
pump
draws
out the
conditioned
oil from
the
degassing
chamber.
This
glandless
feature
ensures
total
isolation
of the
conditioned
oil from
the
atmosphere
and is
essential
for
maintaining
the
quality
of the
conditioned
oil. |

Vacuum
Pumping
system
of high
throughput
capacity
is
provided
for
evacuating
the
degassing
chamber
and is
capable
of
achieving
and
sustaining
a high
degree
of
vacuum. |

Control
Cabinet |
|
The
machine
has a
fuseless
control
panel.
The
machine
is
equipped
with a
sturdy
and
easily
accessible
electrical
control
cabinet.
A mimic
diagram
is
installed
on the
cabinet,
providing
a
continual
display
of the
state of
operation. |
