WXTF Cable Resonance Test System Application The AC withstand
voltage test device is suitable for AC withstand voltage test of
transformers, circuit breakers, switches, GIS systems, cables,
bushings, insulators and other equipment. With high voltage
overvoltage protection, low voltage overcurrent protection, as well
as detuning protection, zero position, flashover protection,
emergency shutdown, undervoltage protection and other multiple
protection functions. It can meet the test requirements of high
voltage and low current equipment, and meet the test requirements
of low voltage and high current equipment. It has a wide range of
application. The frequency adjustment of the AC withstand voltage
test device is divided into coarse adjustment and fine adjustment,
and the test resonance point can be automatically found to ensure
that the resonance frequency does not drift during the whole test
process; the required power supply capacity is small, and the power
supply required for the test is only tested. The capacity is 1/Q;
the volume is small and the weight is light, which is 1/**1/5 of
the common test device; the resonant power supply is a resonant
filter circuit, which can improve the waveform distortion of the
output voltage and obtain a good sinusoidal waveform, effectively
preventing Harmonic peak to the wrong breakdown of the test sample;
with a variety of working modes, **0V or **0V single-phase power
supply, convenient on-site power; multi-mode, modular combination,
can be combined and easy to operate, convenient for on-site use.
Introduction WXTF makes the reactor and tested capacitor in
resonant by adjusting the frequency of the power source, to get
high voltage and heavy current from measured equipment. Now it is a
new method and trend for high voltage test and widely used. WXTF
uses special SPWM digital wave-generate chip, resolution is *6
bits, the frequency adjustment fineness could be 0.1Hz if the
frequency was *0~**0Hz; adopts sine asynchronous fixed wave carrier
modulation, to ensure the waveform output is good in the whole
frequency range; adopts advanced IPM module, ensure the stability
and safety of the device under minimum weight. Features 1.Small in
volume, light in weight. 2.This system need one person to carry the
device less than *0KG, two people less than *0KG. Suitable to carry
on site. 3.Power supply, Single phase: **0V or **0V, convenient to
get power on site. 4.Reactor uses epoxy cast, beautiful and
reliable, suit for all kinds of cables. 5.**0kV and above voltage
level cable withstand voltage test use oil-immersed reactors, when
the weight of single machine is more than **0kg, optional dedicated
small electric cranes Parameters Note: Capacity(KVA) and
voltage(KV) of test system can be produced according to your
requirement. Rated output voltage ≤0~**0kV(AC effective value)
