要約(英語): This paper shows the simulation of Short Line Fault (SLF) interrupting performances for CO2-O2 gas model circuit breakers. Interrupting performances of L90 condition were measured. To simulate the SLF interrupting performances for the CO2-O2 gas circuit breakers, serially connected 3 arc models were adopted. From the arc voltage measurements at L90 condition, the arc parameters of the arc model were estimated. As a result, it was good agreement with the measurements and simulations. The arc parameters of the CO2-O2 arc model were nearly equal to the CO2. From the simulations using the arc model, it proved that most severe SLF condition for the CO2-O2 gas circuit breaker was from L80 to L73. It was able to show that the most severe SLF condition was decided by the energy balance of the post arc resistance.
