摘要
Anumericalsimulationmodelfor252kVpuffercircuitbreakerisconstructed,byusingaprovencommercialcomputationalfluiddynamics（CFD）package,PHOENICS.Themodeltakesintoaccountthemovingpartsinthecircuitbreaker,turbulenceenhancedmomentumandenergytransport,radiationtransport.ThearcingprocessinaSF6puffercircuitbreakerwithtwohollowcontactsissimulatedunderdifferentconditions,andthesimulationresultsareverifiedwithexperimentalresults.Throughsimulation,thepressure,temperatureandvelocityinthearcquenchingchambercanbeobtained.Thesimulationmodelisalsocapableofpredictingtheinfluenceofdesignparametersvariationsonbreakerperformance,andcanthushelptoreducethenumberofshort-circuittestsduringthedesignstage.
