Anode-cathode voltage drop of a rotating arc in an auto-expansion circuit-breaker filled with SF6-N2 mixtures
- Inst. Montefiore, Liege (Belgium); and others
In auto-expansion circuit-breakers, the power dissipated by the arc itself heats the surrounding gas, inducing a pressure build up in the {open_quotes}upstream volume{close_quotes} and giving rise to a gas flow which blows the extinguishing arc. Moreover, in the studied apparatus, a magnetic field, due to the current flowing in a coil, provides arc radial stability and leads to arc rotation which efficiently reduces electrode erosion. In such a circuit-breaker, it is obvious that arc-gas and arc-electrode interactions are essential and govern. the energy balance in the plasma region. This paper deals more specifically with the phenomena occurring at the arc-electrode interfaces. It relates results of experiments carried out to determine the anode-cathode voltage drop when the apparatus is filled with different SF6-N2 mixtures.
