introduction
NAXZ series frequency
resonanttest
system,is mainly
designed for *0kV, *5kV, **0kV, **0kV, substations and loop and all
electrical main AC voltage test equipment design and manufacturing.
Reactor uses more than just separate design, not only can meet the
high-voltage, low-current device test conditions requirements, but
also can meet the low voltage AC voltage testing requirements. It
has a wide scope, is the ground, city, county high voltage test
departments and electrical installation, repair and test
engineering units ideal for pressure equipment.
Also called
name
Frequency resonant, frequency series resonant
, series resonance, series resonant transformer, series resonant
testing device, portable cable withstands testing device, series
resonant system
The Characteristics of the
products
1,Reduce the power capacity greatly. The
series resonant power supply utilizing the resonant reactor and the
sample capacitor resonant generate high voltage and high current.
In the whole system , the power system only provide the part of the
active consumption, therefore, the needed power is  1 / Q of
the testing capacity.
2,Reducing the weight and volume greatly. In
theseries
resonant power supply , not only to eliminate bulky power
regulator, power instruments and other common frequency test
transformer and resonant excitation power simply test the capacity
of 1 / Q, making the system significantly reduces the weight and
volume , usually common test instrument 1/***1/*0
.
3,To improve the output voltage waveform.
Resonant power supply is a resonant filter circuit , can improve
the output voltage waveform distortion, get a good sine wave ,
effectively prevent the harmonic peak error for the test product
breakdown .
4,To prevent large short-circuit current
fault burns. In the series-resonant state, when the test insulation
breakdown weaknesses , the circuit is immediately off the harmonic
, the loop current is rapidly decreased to normal test current of 1
/ Q. The parallel resonant transformer test or way of doing
pressure test , the breakdown current immediately increased several
times, both compared to short-circuit current and the breakdown
current difference between the number of times. Therefore, the
series resonance can effectively find insulation weaknesses,
without the presence of large short-circuit current suffering burns
the point of failure .
5,There will be no recovery
over voltage.
Sample breakdown occurs when the loss of resonance conditions , the
high voltage is also disappear immediately , instantly extinguish
the arc , and the recovery voltage re- building process is very
long, it is easy to reach flash over
voltage again before disconnecting the power , this voltage is
restored process is an intermittent oscillation energy accumulation
process , the process is long.
