在真空击穿过程中，阴极和阳极表面上引发的等离子体耀斑膨胀并碰撞。真空灭弧室等离子体闪焰特性对优化真空灭弧室火花调节具有重要意义。在这里，铜铬合金被广泛用作大容量真空断路器中的电极材料。在这篇文章中，高速光谱进行对等离子体耀斑之间产生的CuCr（Cr-35wt%）阳极和Cu阴极，以阐明等离子体温度，粒子组成，和电子密度。实验结果表明，阳极耀斑的电子数为1024- 1025 m-3，温度约为13000 K。组成阳极火炬的蒸气原子组成比为Cu：Cr = 6：4-7：3，与阳极材料组成基本相同。
During the breakdown process in a vacuum, plasma flares initiated on cathode and anode surfaces expand and collide. The plasma flare behavior is quite important for the optimization of the spark conditioning of vacuum interrupters. Here, copper- chromium alloys are widely used as an electrode material in the large-capacity vacuum circuit breakers. In this article, highspeed spectroscopy is conducted on the plasma flares generated between a CuCr (Cr-35wt%) anode and a Cu cathode in order to elucidate the plasma temperature, particle composition, and electron density. The experimental results show that the anode flare has 1024-1025m-3electron, and its temperature is approximately 13000 K. The composition ratio of vapor atoms consisting the anode flare is Cu:Cr = 6:4-7:3, which is almost the same with that of anode material composition.
