Product Introduction
The XZB Series AC Resonant Test System comprises a frequency-conversion power source, an exciting transformer, high-voltage reactors, and a capacitive voltage divider. In operation, the test object's capacitance (C
C) and the system's reactors (LL) are configured in a series resonance circuit. The voltage divider is connected in parallel with the test object to precisely measure the resonant voltage and provide a reliable overvoltage protection signal.
The system utilizes the series resonance principle, where the frequency-modulated power output is coupled to the circuit via the exciting transformer. By adjusting the output frequency of the power source, the loop reaches a state of resonance between inductance (LL) and capacitance (CC). In this state, the resonant voltage is applied directly to the test object as the test voltage. The XZB series is extensively utilized across the power, metallurgy, petroleum, and chemical industries for high-capacity, high-voltage dielectric strength and preventive testing."
