摘　　要：综述了现有的描述自能灭弧室中电弧和气流特性的几种主要数学方法,并说明了每种方法的特点,根据自行设计的自能灭弧室,提出了灭弧过程中两阶段的电弧与气流场的数学描述方法;特别注意列电弧旋转运动时的湍流和辐射能量的吸收问题。Several mathematical models describing the arc and gas flow of SF6 self - energy quenching procedure are summarized,and the characters of each model are indicated. According to a design of arc quenching chamber,a mathematical model, which describes the two phases of quenching procedure of arc and gas flow,is provided,especially attending to the turbulence of arc rotating and the radiant energy absorbed by cold gas.
