Abstract

CO₂ is identified as a promising alternative gas of SF₆. The magnetohydrodynamics (MHD) arc model is established for a CO₂ circuit breaker. The influence of gas pressure is studied. The simulations are carried out for 0.5 MPa, 0.7 MPa and 0.9 MPa absolute filling pressure, allowing predictions of pressure and temperature distributions. The arc time constant θ and the power loss coe cient Q is extracted. The thermal interruption capability is estimated to grow with increasing filling pressure.
