What Are The Main Characteristics Of Series Resonance?

       In the series circuit of resistance, inductance and capacitance, the phenomenon that the circuit terminal voltage and total current are in phase is called series resonance. The characteristics of series resonance are: the circuit is pure resistive, the terminal voltage and total current are in phase, reactance X is equal to zero, impedance Z is equal to resistance R. At this time, the impedance of the circuit becomes small and the current becomes large, which may produce a high voltage many times the supply voltage on the inductance and capacitance, so the series resonance also becomes the voltage resonance.

The performance characteristics of series resonance are as follows:

1. Simple operation: automatic test (automatic search for resonance point and automatic boosting) and manual test (manual search for resonance point and manual boosting) adapt to different test requirements.

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

3. Automatic mode: only the test voltage and time need to be set; the equipment automatically and accurately frequency and voltage regulation; complete the test and save the data.

4. It has the function of grounding and flashover protection. In case of flashover of the test object or sudden detuning of resonance circuit caused by other reasons, the frequency conversion control power supply will cut off the output automatically and quickly, and display the protection type and flicker voltage value;

5. It can automatically track the change of grid voltage, adjust the voltage in real time, and keep the high voltage stable.

6. The reactor with the same voltage level and capacity has small volume and light weight, small temperature rise under rated load, dry epoxy casting, high mechanical strength, good electrical insulation performance, beautiful and reliable.

7. Variable frequency power control box has large capacity margin, strong protection function, good output waveform, single-phase 220V or three-phase 380V input power supply is universal, which is convenient for on-site power supply.

8. Flexible configuration: the reactor can be used in series / parallel, meet the requirements of different test objects, realize multi-purpose of one machine, with high cost performance.
