Abstract :
The influence of various gas inclusions upon thermal plasma was investigated from the viewpoint of finding alternatives to SF6 as an arc-quenching medium in a high voltage circuit breaker. The inductively coupled thermal plasma (ICTP) technique was used to sustain thermal plasma. The effect of SF6 and six environmental-benign gas inclusions on plasma temperature and impedance was measured. The result indicated that SF6 causes the plasma radius reduction and plasma temperature decline only with a several percentage inclusion. The similar tendency was found for CO2, while it was not found for the other five gases. This indicates that CO2 has a higher plasma-quenching property than the others in the experiment.
