“…There are a number of recent papers concerning the simulation of the whole high current phase in puffer circuit breakers [8∼10] with varied levels of success. The prediction of pressure in the puffer cylinder agrees reasonably well with measurement if the uncertainties in measurement are taken into account, but the accuracy of arc voltage prediction is often either omitted in the discussion [9,10] or poor [8] . This is possibly caused by inappropriate treatment of arc rooting.…”

A numerical simulation model for 252 kV puffer circuit breaker is constructed, by using a proven commercial computational fluid dynamics (CFD) package, PHOENICS. The model takes into account the moving parts in the circuit breaker, turbulence enhanced momentum and energy transport, radiation transport. The arcing process in a SF6 puffer circuit breaker with two hollow contacts is simulated under different conditions, and the simulation results are verified with experimental results. Through simulation, the pressure, temperature and velocity in the arc quenching chamber can be obtained. The simulation model is also capable of predicting the influence of design parameters variations on breaker performance, and can thus help to reduce the number of short-circuit tests during the design stage.
