3,Main
functions
of
the
system:
1)
The
variable
frequency
power
supply
adopts
a
linear
power
amplifier
circuit,
which
has
a
perfect
sine
wave
output
and
low
waveform
distortion
2)
With
automatic
voltage
stabilization
adjustment
function
3)
Safe
and
reliable.
A
variety
of
protections
are
integrated
in
this
device,
including:
discharge
breakdown
protection,
over-voltage,
over-current
setting
protection,
output
short-circuit
protection,
boot
zero
protection,
bridge
arm
amplifier
circuit
protection,
power
curve
protection,
etc.
When
any
kind
of
protection
appears,
the
device
immediately
blocks
the
test
voltage
output
and
cuts
off
the
main
circuit
power
supply
to
ensure
the
safety
of
the
test
personnel,
the
tested
product
and
the
test
system
4)
The
high-voltage
measurement
signal
is
transmitted
by
optical
fiber
to
completely
isolate
the
high-voltage
and
low-voltage
circuits
5)
Two
control
modes:
automatic/manual
6)
320*240
dot
liquid
crystal
display
and
multiple
rotating
mice
provide
a
friendly
man-machine
interface,
easy
and
quick
operation
and

and
truly
"just
look
at
it"
7)

8)
The
output
frequency
is
continuously
adjustable
within
the
range
of
20-300Hz
9)
The
output
voltage
is
continuously
adjustable
within
the
range
of
0～350V
10)

etc.;
2)
It
has
the
function
of
setting
test
parameters
such
as
test
voltage
and
time;
5,Other
features
of
the
product:
1)
The
oil-filled
equipment
in
the
device
does
not
leak
oil.
2)
All
metal
shells
in
the
device
are
rust-proof
and
anti-corrosion
treatment,
and
the
coating
is
uniform
and
beautiful.
The
main
components
have
stainless
steel
nameplates
and
terminal
signs.
3)
The
device
can
be
stored,
assembled
and
disassembled
indoors
and
outdoors;
the
protection
function
is
complete.
The
manufacturer
guarantees
that
the
control
equipment,
transformers,
reactors,
etc.
of
the
device
are
at
1.1
times
the
rated
voltage,
and
if
the
high-voltage
side
sample
flashovers
to
the
ground
during
the
test,
it
will
not
cause
personal
injury
and
the
test
equipment
will
not
cause
harmful
mechanical
and
thermal
stress.
Electrical
performance
is
damaged
or
damaged.
4)
Each
part
of
the
equipment
has
a
nameplate
that
conforms
to
the
national
standard,
the
words
and
symbols
are
clear
and
durable,
and
the
nameplate
is
clearly
visible
when
the
equipment
is
