Nitrogen is one of the popular protective gases in switches with good chemical stability and high performance-cost ratio. Some trace gas impurities in nitrogen have obvious influence on arc
resulting in the changes of arc quenching properties and erosion characteristics of contacts. This paper proposes a microscopic model of thermal equilibrium arc burning in mixture of nitrogen and oxygen
and calculates the microscopic parameters of arc with this model. The influence of oxygen on arc is investigated by changing the ratio of nitrogen to oxygen
