摘　　要：将压气式SF_6断路器与操动机构进行了二维冷态气流场联合求解,计算了断路器的空载分闸特性及分闸过程中各时刻灭体室内的冷态气流场。应用Taylor—Galerkin法对可压缩气体非稳态控制方程组进行了数值求解。Combined with the opening characteristics of the operating device the gas flow field in the arc chamber of SF6 puffer circuit breaker is calculated. The Taylor-Galerkin finite element method is used to solve the unsteady two-dimensional/axisymmetric Euler equations.
