Variable Frequency Resonant Test SystemZCVF-C

1.Due to resonant reactive power full compensation, the power of the power supply and equipment is only less than 1/10 of the required capacity of the test object(1/Q10), small size of the same capacity, light weight, large output capacity of the device and the required configuration of power supply capacity is small, cheap, convenient and safe operation.

2.Series resonance is actually a current filter circuit, which makes the current passing through the test subject basically basic wave current, and the waveform distortion rate(THD) of output voltage is extremely small, which is better than all existing ac voltage withstand devices.

3.The short-circuit current after the test sample flashover or breakdown is only less than 1/10 of the test current before short-circuit(1/Q), which can effectively prevent the damage to the fault point from expanding after breakdown.

4.After flashover, it will automatically extinguish the arc immediately. After extinguishing the arc, it is a long process(seconds)to restore the resonant state voltage. It is a steady-state establishment process, which has no voltage overshoot and no danger of overvoltage recovery in microsecond and millisecond transient processes.

5.The whole set equipment use advanced principle and advanced casting process. The whole system is dry structure, which use finishing drive mechanism to greatly reduce the noise of equipment operation.

6.Excitation transformer is high and low voltage double output, with rectifier silicon reactor, and also can test the generator dc voltage test.

7.Equipped with dry type columnar voltage regulator, good output waveform and good stability

8.The inductance of the fixed reactor and the adjustable reactor is reasonably configured, with good resonance point and no resonance blind area for the test objects with different capacitance

9.The operating system can not only adjust the voltage and inductance, but also monitor the power factor, side current of high voltage, test voltage of high voltage, output voltage of low voltage and the rise and fall value of air gap of the loop in real time, with overcurrent and overvoltage protection.
