Development of a Chemically Non-Equilibrium Model on Decaying SF6 Arc Plasmas

摘要：

This paper describes the development of a chemically non-equilibrium model on an SF6 arc plasma in decaying phase. The SFr, arc plasma in decaying phase can be seen in a high voltage SF,, gas circuit breaker during a large current interruption process. The developed model here does not assumes chemical equilibrium in the arc plasma, although the conventional numerical model often assumes the equilibrium. This developed model accounts for 19 species including molecules, atoms, monatomic ions, polyatomic ions and the electron. It also takes into account totally 122 reactions including dissociation, ionization, and other chemical reactions in SF6 plasmas. As a result, transient distribution of the temperature and chemical reaction fields were calculated for SF6 arc plasma under a free recovery state for a fundamental study.
