(1) Cable frequency conversion resonance device (2), generator AC voltage resistance device (3), substation electrical equipment AC voltage withstand resonance device (4), CVT inspection resonance booster device Product features:
1. High stability and reliability. The system adopts imported power components as the core of power conversion, with stable voltage output and frequency output, reasonable EMC design, and perfect protection function. After many high-voltage direct-to-ground short-circuit tests, the system remains intact and the system has a strong overload. ability.
2. Perfect protection function. With zero protection (voltage output control knob is not zero, prohibit system startup), overvoltage protection, overcurrent protection, flashover protection and other functions, to ensure the reliability of the system.
3. System human-computer interaction interface is friendly. The test parameter settings, test control, and test results are displayed on the same screen, which is intuitive and clear, and has automatic timing and operation prompting functions. Full touch screen operation and display, with test data saving and query functions.
4. Support multiple test modes. The system supports such test modes as "auto tuning + manual pressure adjustment", "auto tuning + auto voltage regulation", and "manual tuning + manual pressure adjustment". It is recommended to use the "auto tuning + manual pressure adjustment" mode to quickly find the resonance point. , but also through the manual pressure control test process, higher security.
5. Automatic tuning is powerful. When the system automatically tunes, it automatically sweeps from 30Hz to 300Hz to display the sweep frequency curve. The user can intuitively see the system tuning process. After the sweep frequency is completed, the system will initially find the resonant frequency in the range of ±5Hz according to the resonant frequency. The frequency sweep is performed with a resolution of 0.01 Hz, and the resonant frequency is accurately locked.
Frequency conversion series resonant test equipment is the use of series resonant principle, the use of excitation transformer to stimulate the series resonant circuit, adjust the output frequency of the inverter controller, so that the loop inductance L and the sample C series resonance, resonant voltage is added to the sample voltage. The frequency conversion resonance test device is widely used in electric power, metallurgy, petroleum, chemical industry and other industries. It is suitable for the transfer and preventive testing of large-capacity, high-voltage capacitive test products.
