Introduction: - Frequency Variable Series Resonance Test System is mainly used for ac withstand voltage test of cross-linked cable,
hydraulic generator, main transformer, bus, GIS, etc.
- It has a wide range of application and is an ideal withstand
voltage equipment for local, municipal and count-level high voltage
test departments and electric power installation and repair and
test engineering units.
- It is mainly composed of frequency conversion control power supply,
excitation transformer, reactor, capacitor voltage divider and
compensation capacitor (optional).
Functions: - Frequency Variable Series Resonance Test System has protection functions such as overvoltage, overcurrent, zero
start, system detuning (flashover), overvoltage and overcurrent
protection values can be set according to user needs, and flashover
protection action when the sample flashes to protect the product.
- The entire unit is lightweight and easy to use on site.
- The device has three working modes, which is convenient for the
user to flexibly select according to the site conditions and
improve the test speed. The working modes are: fully automatic
mode, manual mode, and automatic tuning manual boost mode.
- Frequency Variable Series Resonance Test System can store and print data off-site, and the stored data number is a
number, which is convenient for users to identify and find.
- When the device is automatically swept, the starting point of the
frequency can be arbitrarily set within the specified range, and
the large screen of the liquid crystal displays the scanning curve,
which is convenient for the user to intuitively know whether to
find the resonance point.
- The DSP platform technology is adopted, which can conveniently
increase or decrease functions and upgrades according to user
needs, and also makes the human-machine exchange interface more
humanized.
