Description
The product combined modern digital frequency conversion advanced
technology, and adopts microcomputer control. Voltage boost and
reduction, measurement, protection all are automatic. Because of
entire electronization, so small size and light weight, big screen
LED displaying, clear and visually, can show output waveform,
printing test report. Design index is fully suitable forn (Power
equipment special-purpose measuring instrument general technology
condition, 4th part: ultralow frequency high voltage generator
general technology condition) electric industrial standard and use
very conveniently. Presently domestic and overseas all adopt
mechanical method to perform modulation and demodulation for
ultralow frequency signal generation. So exist
abnormal sine
wave, big measure deviation, HV spark discharge, heavy
equipment,
moreover sine wave 2 and 4 quadrant needs big power high voltage
resistor to discharge and reshape. So it has big power consumption.
The product can overcome those weak points and have below
characteristics.
Features:
(1), Adopt single structure for ultralow frequency with lower or
equal *0kV rated voltage (1 set booster);Â Cascaded structure
is for higher than *0kV ultralow frequency  (2 sets
booster). So reduce weight largely and increase loading capability.
Moreover 2 sets booster can be independently as use for low voltage
grade ultralow frequency.
(2), Current, voltage and waveform data all can be captured from
high voltage side, so data is accurate.
(3), Have overvoltage protected function. If output is over
specified voltage, instrument will shut down and within *0ms
action.
(4), Have overcurrent protected function:designed for high-low
voltage double protection,high voltage side can shut down and
protect based on specified value; low voltages side can shut down
and protect if over rated current,time of action all are lower
than *0ms.
(5), High voltage output protected resistor is designed inside of
booster, so no need to connect protected resistor.
(6), Because of adopting high and low closed-loop negative feedback
control circuit,so no output capacitance raise effect.
