Advantages of resonance? HVHIPOT specializes in the production of series resonance. To find series resonance, choose HVHIPOT.
Resonance
Resonance is a physical harmonic vibration, in which the acceleration of an object is proportional to the displacement from the equilibrium position and is always directed towards the equilibrium position by the restoring force. The dynamic equation is F=- kx. The phenomenon of resonance is that the current increases and the voltage decreases. The closer it is to the resonance center, the faster the ammeter, voltmeter, and power meter rotate, but the difference to a short circuit is that there will be no zero sequence quantity.
Resonance application
The radio utilizes the resonance phenomenon. When turning the knob of the radio, it is changing the natural frequency of the circuit inside. Suddenly, at a certain point, the frequency of the circuit became equal to the frequency of the electromagnetic waves that were previously invisible in the air, and they resonated.
Advantages of resonance
1. High stability and reliability. The system uses imported power components as the core of power conversion, with stable voltage and frequency output, reasonable electromagnetic compatibility design, and complete protection functions. After multiple high-voltage direct to ground short circuit tests, the system still remains intact, and at the same time, the system also has strong overload capacity.
2. The automatic tuning function is powerful. When the system is automatically tuned, it automatically scans from 30Hz to 300Hz and displays the sweep curve, allowing users to intuitively see the tuning process of the system; After the frequency sweep is completed, the system performs a fine frequency sweep with a resolution of 0.01Hz within its ± 5Hz range based on the resonance frequency point preliminarily found by the sweep, and finally precisely locks the resonance frequency.
3. Support multiple experimental modes. The system supports test modes such as “automatic tuning+manual voltage adjustment”, “automatic tuning+automatic voltage adjustment”, “manual tuning+manual voltage adjustment”, etc. It is recommended to use the “automatic tuning+manual voltage adjustment” mode, which can quickly find the resonance point and control the test process through manual voltage adjustment, with higher safety.
4. The system has a user-friendly human-computer interaction interface. The experimental parameter settings, experimental control, and experimental results are displayed on the same screen, which is intuitive and clear, and has automatic timing and operation prompt functions. Full touch screen operation and display, with the function of saving and querying experimental data.
5. The protection function is complete. Equipped with zero position protection (prohibiting system startup when the voltage output control knob is not in zero position), overvoltage protection, overcurrent protection, flashover protection, and other functions, ensuring the reliability of the system.
