The main characteristics of series resonance are:
1. The operation is simple and can be divided into two types: automatic testing and manual testing. The former can automatically find the resonance point and boost the voltage, while the latter can manually find the resonance point and boost the voltage. The two modes are suitable for different testing requirements.
2. Can set the test voltage, frequency range, protection current, and pressurization time.
3. In automatic mode, everyone only needs to set the test voltage and time; The equipment automatically and accurately adjusts frequency and voltage; Complete the experiment and save the data.
4. It has grounding and flashover protection functions. When a flashover occurs in the test sample or the resonant circuit suddenly loses resonance due to other reasons, the variable frequency control power supply will immediately automatically and quickly cut off the output, while also displaying 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 and 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.
