One、Product overview
This device principal for 220KV/25000KVA Main transformer neutral point AC
voltage withstand test. The reactor is designed to meet the requirements of low voltage
AC voltage test, such as high voltage and low voltage, and it can meet the requirement of
low voltage AC voltage test with 10kV cable.
The device is composed of a frequency conversion control power supply, an excitation
transformer, a reactor, a capacitor voltage divider, and a compensating capacitor.
1.1 Application of series resonance in power system：
1.1.1、The required power capacity is greatly reduced. Series resonant power supply is
the use of the resonant reactor and the capacitor voltage to generate high voltage
and high current. In the whole system, the power supply is only required to provide
active power consumption of the system, therefore, the power required to test the
power is only 1/Q.
1.1.2、The weight and volume of the device is greatly reduced. The series resonant power
supply, not only saves large power heavy pressure adjusting device and ordinary
power frequency test transformer and resonant excitation power supply only needs to
test the capacity of 1/Q, which makes the system weight and volume greatly reduced,
generally for ordinary test device 1/10.
1.1.3、Improve the output voltage waveform. Resonant power supply is a resonant filter
circuit, can improve the output voltage waveform distortion, get a good sinusoidal
waveform, effectively preventing the harmonic peak of the test sample of the false
breakdown.
1.1.4、Prevention of large short-circuit current burn. In series resonant state, when the
insulation of the test sample is breakdown, the circuit is immediately removed, and
the loop current is rapidly decreased to the normal test current 1/Q. And parallel
resonance or test transformer mode to do the test, the breakdown of the current rise
in a few times, the difference between the short circuit current and the breakdown
current of several hundred times. Therefore, the series resonance can effectively find
the insulation weakness, and there is no big fault point of the fault of the short circuit.

1.1.5、Will not appear any recovery over voltage. When the product is broken down, the
high
voltage is lost immediately, the arc is extinguished immediately, and the recovery
voltage is very long, and it is easy to break off the power supply.
1.2 The main functions and technical characteristics of the
FM resonance device of our company：
The device has the protection function such as over voltage, over current, zero
position start, and the system is out of order. The protection value can be adjusted
according to user's need, and the flashover voltage of the test sample can be recorded.
1.2.1、The whole unit weight is light, easy to use in the field..
1.2.2、The device has three working modes, which is convenient for the user to choose
according to the situation of the scene, and to improve the test speed.
Work mode is: automatic mode, manual mode, automatic tuning manual boost mode.
1.2.3、Can store and remote print data, the data is stored in the digital, convenient to help
users identify and find.
1.2.4、Device automatically sweep frequency when the starting point can be set in the
specified range, sweep direction can be up and down, while the LCD screen display
scan curve, easy to understand whether users can find the resonance point.
1.2.5、Using the DSP platform technology, it can be convenient for the user to increase or
decrease the function and upgrade, but also makes the man-machine exchange
interface more humane.
