Abstract
Previous work shows that the interruption capability of a gas not only depends on the its material properties but also on the flow field because turbulence plays an important role in the interruption process. Recent experimental results on maximum interruptible di/dt in a model circuit breaker show that the interruption capability of CO2is about 60% that of pure SF6. A computational study of the interruption process in the above model circuit breaker with CO2as the working gas has been carried out to affirm the experimental interruption capability of CO2. Through detailed analysis of the results mechanisms responsible for the difference in the interruption capabilities of the two gases are identified and the performance dependence on material properties discussed. The suitability of turbulence coefficient is also discussed.
