HZXB Series Resonance Withstand Test Set Catalog

The variable frequency series resonance test device, also called series resonance. lt is composed of a variable frequency power supply, an excitation transformer, a reactor and a capacitor divider. The capacitance of the test object and the reactor form a series resonant connection mode; the voltage divider is connected in parallel to the test object for measuring the resonance voltage on the test object and making an overvoltage protection signal; the frequency modulation power output is coupled via the excitation transformer A series resonant tank that provides excitation power for series resonance.
