technical
advantage
of
engines
in
the
aspects
of
reducing
exhaust
gas,
decrease
fuel
consumption
rate
and
good
noise
level
control.
1.4
Alternator
All
of
the
alternators
chosen
by
HYUNDAI
Power
are
single
bearing
self
‐
excitation
brushless
alternators
with
the
attributes
of
international
top
brand.
By
citing
Stamford
alternator
as
an
example,
we
can
illustrate
the
features
of
our
alternators
as
follows:
◆
Four
polar
brushless
self
‐
excitation,
single
bearing,
insulation
class
is
H
and
protection
level
is
IP22.
◆
Stators
are
wound
to
2/3
pitch,
which
can
effectively
eliminates
triple
and
curbs
waveform
deformation
of
output
voltage.
When
in
parallel
with
the
mains
or
other
generator
sets,
this
type
of
winding
can
effectively
avoid
excessive
neutral
currents
and
reduces
inductive
heat.
◆
Before
being
assembled,
rotors
need
to
pass
dynamic
balance
testing.
The
improved
damper
reduces
voltage
deviation
and
heat
under
unstable
load.
◆
The
exciter
rotor
output
is
fed
to
the
main
rotor
through
a
three
phase
full
wave
bridge
rectifier,
the
rectifier
is
protected
by
a
surge
suppressor
against
surges
caused
by
short
circuit
or
out
‐
of
‐
phase
paralleling.
◆
Automatic
voltage
regulator
has
the
feature
of
automatic
load
curtailment
which
is
used
to
protect
the
engine,
and
make
it
possible
to
add
full
load
to
the
alternator
at
one
time.
Steady
state
voltage
adjusting
rate
can
reach
±1%
(under
certain
requirements,
steady
state
voltage
adjusting
rate
can
meet
±0.5%).
If
PMG
system
is
chosen,
the
motor
will
have
high
starting
capacity
and
the
ability
of
interference
rejection
for
the
deformed
voltage
waveform
fed
by
the
main
stator
generated
by
non
‐
linear
load(such
as
silicon
control
DC
electric
motor,
UPS
etc).
◆
Telephone
influence
factor
TIF<50,
telephone
harmonic
wave
factor
THF<2%
,
the
brushless
style
and
high
quality
AVR
ensures
low
interference
with
Radio.
1.5
Cooling
System
The
engine
cooling
system
is
water
cooled.
The
water
cooled
system
is
comprised
of
a
radiator
a
pusher
fan
and
thermostat.
The
alternator
has
its
own
internal
fan
to
cool
the
alternator
components.
1.6
Electrical
System
The
engine
electrical
system
is
12
volt
or
24
volts
DC,
negative
ground/earth.
This
system
includes
an
electric
engine
starter,
a
battery
and
a
battery
charging
alternator.
For
DC
12
volts
electrical
system
one
battery
is
given.
For
24
volt
system
two
lead
‐
acid
batteries
are
given.
Other
types
of
batteries
may
be
fitted
if
they
were
specified.
1.7
Coupling
Engine
and
alternator
are
firmly
joined
by
a
coupling
cone
that
guarantees
the
proper
assembly
coaxiality
Single
‐
support
machines
are
also
used
a
special
flexible
disk
is
used
in
place
of
a
flexible
coupling.
1.8
Fuel
Tank
and
Base
Frame
The
engine
and
alternator
are
coupled
together
and
mounted
on
a
heavy
duty
steel
base
frame.
This
base
frame
includes
a
fuel
tank
with
capacity
of
approximately
8
hours
operation
under
variable
loads.
The
tank
is
complete
with
filling
cap
and
fuel
level
gauge
and
is
connected
by
flexible
joints
to
the
intake
piping
and
to
the
overflow
piping
containing
fuel
from
the
injector
drain.
Big
capacity
generator's
fuel
tank
is
separate
from
generator
set.
1.9
Control
Panel
All
models
of
HYUNDAI
Power
generator
sets
use
high
grade
control
panel.
The
core
of
control
panel
is
an
imported
digital
diesel
engine
control
module,
which
has
been
facilitated
with
more
complex
functions
such
as
further
monitors,
demonstration,
people
‐
module
dialogue,
distance
communication
and
protection
etc.
HYUNDAI
Power
generator
set
control
panel
use
steel
plate
structure,
which
ensures
security
and
reliability,
and
the
surface
of
it
has
been
treated
with
static
powder
painting.
The
outside
appearance
is
beautiful.
Special
lock
has
been
used
to
fix
it.
It
has
been
designed
for
easy
maintenance.
1.10
Optional
for
Canopy
Generator
Set
1.10.1
External
antifreeze
adding
hole
Our
generator
sets
has
been
facilitated
with
external
antifreeze
filling
hole.
When
user
intends
to
add
antifreeze,
He
only
needs
to
open
the
antifreeze
filling
hole
on
the
roof
of
canopy
and
the
radiator’s
pressure
valve
cap
to
directly
add
antifreeze
to
the
hole,
and
easily
watch
the
anti
‐
freeze
level.
