RADIATIVE-TRANSFER IN SF6 AND SF6-CU ARCS

The radiative transfer in SF6 and SF6-Cu arcs was calculated using the method of partial characteristics. The partial sources and sinks of r adiation were tabulated for a temperature range 300-30000 K and a pres sure range 0.1-1 MPa. The method was applied to one- and three-dimensi onal calculations of radiative transfer and in are plasma models. In c ircuit breakers, radiation absorption increases the upstream pressure either by direct heating or by accentuating the clogging effect in the nozzle throat.
