Product Introduction
XZB series consists of frequency conversion power supply, excitation transformer, reactor and capacitance divider. The capacitor and reactor of the tested equipment form the connection way of series resonance. The voltage divider is connected in parallel to the tested equipment to measure the resonant voltage as overvoltage protection signal as well. The frequency modulation power output is coupled to the series resonance circuit by the excitation transformer, providing the excitation power of series resonance. It exerts series resonance principle, uses excitation transformer to motivate series resonant loop, and adjust the output frequency of the director to make the loop inductance L and measured equipment C in series resonant, and the resonant voltage is the voltage added to the tested equipment.XZB series is widely used in electric power, metallurgy, petroleum, chemical industry and other industries, apply to large capacity, high voltage capacitance test and preventive test.
