摘要
研制了大电流、大库仑两电极气体开关,并研究了其静态特性,给出了开关自击穿概率拟合公式。结果显示:自击穿电压与工作气压基本呈线性递增关系;随着气压的升高,自击穿电压的分散性逐渐增大。数值模拟和实验对比显示,开关自击穿电压的分散性基本满足两参数威布尔分布。该项研究成果能够为选择开关的工作电压及充气压力提供参考,以满足能源系统可靠性的要求。
A high-Coulomb two-electrode spark gap switch was developed. Its static characteristic was studied and the fitting formula for its self-breakdown probability was derived. It is found that the self-breakdown voltage increases linearly with the working gas pressure, and the voltage becomes more dispersive as the pressure increases. The comparison results between numerical simulation and experiments show that, the self-breakdown probability agrees well with the Welbull relationship with two parameters. This work could be a reference for the selection of switch working pressure and inflated-gas pressure, which meets the stability demand of the power conditioning system.
