Variable frequency series resonance

The variable frequency series resonance tester mainly consists of a variable frequency controller, excitation transformer, high-voltage reactor, high-voltage voltage divider, etc. Widely used in industries such as power, metallurgy, petroleum, and chemical, it is suitable for the handover and preventive testing of high-capacity, high-voltage capacitive samples.

　　Variable frequency series resonance testerProduct Features:

◆ High stability and reliability. The system adopts imported power components as the core of power conversion, with stable voltage and frequency output, reasonable electromagnetic compatibility design, and * protection function. 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.

◆ Automatic tuning function *.Variable frequency series resonance testerWhen 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 the ± 5Hz range based on the resonance frequency point preliminarily found by the sweep, and then precisely locks the resonance frequency.

Support multiple experimental modes. The system supports test modes such as "automatic tuning+manual voltage regulation", "automatic tuning+automatic voltage regulation", "manual tuning+manual voltage regulation", etc. It is recommended to use the "automatic tuning+manual voltage regulation" mode, which can quickly find the resonance point and control the test process through manual voltage regulation, with higher safety.

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.

◆ Protection function *. 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.
