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.
1. This withstand voltage equipment has small volume, light weight and portable test system.
2. This system requires that the weight can be moved on site by a single person should not exceed 30kg, and it can be moved by two people should not exceed 60kg, therefore it is suitable for on-site working.
3. The power supply adopts 220V single-phase power supply or 380V single power supply, which is convenient for on-site power collection.
4. The reactor adopts dry epoxy pouring, which is beautiful and reliable, suitable for all kinds of cables.
6. Equip with the function of monitoring peak value according to international standard, which can monitor high voltage test waveform in real time.
7. Easy to operation, big LED screen.
8. With its own micro printer, print and save test data at any time.
