摘　　要：利用 45°锥体不锈钢反射镜和分幅式变象管高速相机 ,研究了环状不锈钢和弹簧两种间隙电极结构的气体开关在不同气压下自击穿和触发击穿时的放电通道。实验表明 :两种间隙电极结构开关触发击穿放电通道数比自击穿多 ;同等实验条件下 ,环状不锈钢间隙电极开关放电稳定性比环状弹簧间隙电极开关好 ,弹簧电极的均匀性和支撑需要进一步完善。The discharge channel is one of the crucial parameters of describing the properties of gas switch. The 45° cone reflector made of stainless steel is designed. The discharge channels of two different structural switches whose gap electrodes are stainless steel ring and spring are studied by a high speed framing camera under self-breakdown and triggering breakdown voltage, respectively. The primary results indicate that the optical photography based on a 45° cone reflector and high speed framing camera is an efficient and reasonable method to investigate the discharge channel properties of gas spark switch. The elementary results show that the discharge channel properties of gas spark switch. The elementary results show that the discharge channel numbers under triggering breakdown are more than that of self-breakdown, and the discharge stability of gap electrodes made of stainless steel ring is better than that of spring electrodes. The supporting method of spring electrodes needs to be improved.
