摘　　要：在烟气脱硫脉冲电源中采用场畸变火花间隙为开关，并在探讨开关电极各种形状基础上以旋转椭圆近似法优化设计一近似Ｂｏｒｄａ 电极形状为开关主电极形状，实验研究表明它触发性能可靠，可实现低脉冲幅值触发，且其放电点分布均匀，大大减小了电极烧损。The field distortion spark gap used as the switch in pulse generator for desulphurization of flue gases is studied. Various electrode shapes are discussed, and Borda is selected. Using the rotating ellipse approximation method to optimize the electrode shape, an experimental study has been carried out on the triggering feature and discharge distribution property of the optimum designed switch. As a result the switch can be triggered reliably by relative low triggering pulse as well as the uniform discharge distribution has been acquired, which can prolong the life level of switch.
