Wuhan UHV specializes in producing series resonant devices (also known as variable frequency series resonant devices). Next, we will share with you the characteristics of variable frequency series resonant devices.

The main characteristics of series resonance are:

1. Easy to operate: Two modes of automatic testing (automatic search for resonance point and automatic boost) and manual testing (manual search for resonance point and manual boost) are suitable for different testing requirements.  

2. Can set the test voltage, frequency range, protection current, and pressurization time.

3. Automatic mode: only need to set the test voltage and time; Automatic precision of equipment Quasi frequency regulation and voltage regulation; Complete the experiment and save the data.  

4. It has grounding and flashover protection functions. In the event of flashover of the test sample or sudden loss of resonance in the resonant circuit caused by other reasons, the variable frequency control power supply will immediately automatically and quickly cut off the output, and display the protection type and flashover voltage value;  

5. It can automatically track changes in grid voltage, adjust voltage in real time, and maintain stable high voltage.

6. Reactors of the same voltage level and capacity have smaller volume and lighter weight; Low temperature rise at rated load; Adopting dry epoxy casting, it has high mechanical strength, good electrical insulation performance, and is aesthetically pleasing and reliable.  

7. The variable frequency power supply control box has a large capacity margin; Strong protection function; Good output waveform; Single phase 220V or three-phase 380V input power supply is universal, convenient for on-site power supply.  

8. Flexible configuration: The reactor can be used in series/parallel to meet the requirements of different test samples, achieving multiple uses for one machine and high cost-effectiveness.
