At high interrupting current, it is well known that the polytetrafluoroethylene (PTFE) wall of a nozzle in GCBs is ablated and the nozzle is temporarily filled with pure PTFE vapor. The authors performed magnetohydrodynamics analysis of gas-blasted arcs coupled with radiative analysis (that is called P1 approximation) to calculate radiative heat transfer under PTFE-100% environment. In this presentation, numerical results regarding radiative properties of pure PTFE thermal arcs in GCBs will be reported.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e要約(英語): \u003c\/strong\u003eRadiative heat transfer plays an important role in energy balance of thermal arcs in gas circuit breakers (GCBs) at high current.
