Structural Features
The following is the introduction of the main parts of the single-phase pole-mounted transformer. The main parts(accessories) on the single phase pole mounted transformer include high voltage bushing, low voltage bushing, oil fill valve, oil drain valve with the sampler, and pressure relief valve, Lighting arrester, Internal current limiting fusing, Circuit breaker.
1.
High
voltage
bushing
The
main
material
of
high
voltage
bushing
is
porcelain
and
its
main
role
is
to
connect
high
voltage
winding
and
external
high
voltage
lines,
insulation
protection,
protection
against
external
intrusion,
heat
conduction
and
heat
dissipation,
etc.,
to
ensure
the
normal
operation
and
safety
of
the
transformer.
2.
Low
voltage
bushing
There
are
two
types
of
low
voltage
bushing
as
spade
type
and
clip
type.
3.
Oil
fill
valve
The
role
of
the
oil
filling
valve
on
the
single
phase
pole
mounted
transformer
is
to
fill
the
insulation
oil
into
the
tank.
4.
Oil
drain
valve
with
sampler
The
oil
drain
valve
and
sampler
on
the
single
phase
pole
mounted
transformer
are
used
to
discharge
air
and
moisture,
remove
sediment
and
impurities,
ensure
the
quality
and
performance
of
the
oil
inside
the
transformer,
and
ensure
the
safe
and
stable
operation
of
the
transformer.
Meanwhile,
we
can
collect
oil
samples
for
analysis
and
testing.
5.
Pressure
relief
valve
The
pressure
relief
valve
on
the
single
phase
pole
mounted
transformer
is
mainly
used
to
protect
the
safe
operation
of
the
transformer,
maintain
normal
working
conditions,
and
adjust
the
gas
pressure
inside
the
transformer
to
ensure
its
stability
and
reliability.
6.
Lighting
arrester
The
lighting
arrester
keeps
the
transformer
safe
from
power
surges
caused
by
lightning,
switching,
and
other
HV
sources.
It
shunts
high
voltage
surges
by
grounding
to
avoid
the
direct
impact
of
the
transformer
itself.
7.
Internal
current
limiting
fusing
The
fuse
is
used
to
limit
the
transformer
winding
from
being
damaged
when
there
are
overload
currents.
8.
Circuit
breaker
One
secondary
circuit
breaker
is
above
the
winding
inside
the
tank
and
here
are
the
operating
handle,
overload
reset,
and
signal
light.
It
has
the
function
of
thermal
protection,
low
oil
lever
protection,
and
allowing
a
percentage
of
power
to
go
through
the
breaker
to
restore
service
when
it
trips.
