Summarization
SG series single - phase and three - phase dry type transformer adopts high quality material and advanced technology , it has advantages of damp - proof and convenient maintenance, it can be applied to such power transmission and distribution places like underground railway , high building, airport, station, wharf, enterprise, tunnel, etc. It is mainly used in power supply occasions of AC 50~60Hz and voltage less than 500V.
Application
1)
Electrochemical
industry:
It's
the
most
industries
apply
to
rectifier
transformer,
electrolyze
non-ferrous
metal
compounds
for
aluminum,
magnesium,
coppr
and
other
metal.
2)
Traction
with
dc
power
supply:
It
is
used
in
dc
grid
of
mining
or
city
electric
locomotive
dc.
Due
to
the
valve
side
joint
overhead
lines
occur
the
short
circuit
fault
always,
dc
load
amplitude
becomes
larger
and
electric
locomotive
starts
frequently,
which
will
cause
varying
degrees
of
short
time
overload.
Therefore,
temperature
rise
and
current
density
of
rectifier
transformer
will
achieve
a
lower
limit.
The
impedance
is
about
30%
greater
than
the
corresponding
power
transformer.
3)
Transmission
with
dc
power
supply:
It
is
mainly
used
in
dc
motor
power
supply
in
the
electrical
drive,
such
as
the
armature
and
excitation
of
rolling
machine.
