In this paper, the synergistic effect of CF 3 I mixed gas is theoretically analyzed using the Boltzmann method and experimentally studied under different applied voltage, pressure and electric field inhomogeneity. The experimental results show the inversion of synergetic effect, which reflects the influence of external conditions on synergetic effect. The results show that CF 3 I/N 2 and CF 3 I/CO 2 mixtures under slightly uneven electric field at normal pressure have synergistic effect. CF 3 I/CO 2 mixtures under power frequency voltage and lightning impulse have better synergistic effect than CF 3 I/N 2 . The effect of macro parameters on synergetic effect is different for different buffer gases. For CF 3 I/N 2 mixture, the synergistic effect of the mixture can be improved by increasing the pressure and increasing the electrode gap distance. For CF 3 I/CO 2 , due to the abnormal breakdown of the mixture, negative synergistic will occur at some pressure and gap distance.

CF3I混合气体与不同缓冲气体协同效应研究


本文利用玻尔兹曼方法对CF 3 I混合气体的协同效应进行了理论分析，并在不同外加电压、压力和电场不均匀性下进行了实验研究。实验结果呈现出协同效应的反转，反映了外部条件对协同效应的影响。结果表明，CF 3 I/N 2 和CF 3 I/CO 2 混合物在常压下稍不均匀的电场下具有协同作用。 CF 3 I/CO 2 混合物在工频电压和雷电冲击下比CF 3 I/N 2 具有更好的协同效应。对于不同的缓冲气体，宏观参数对协同效应的影响是不同的。对于CF 3 I/N 2 混合物，可以通过提高压力和增大电极间隙距离来提高混合物的协同效应。对于CF 3 I/CO 2 ，​​由于混合物的异常分解，在一定压力和间隙距离下会出现负协同作用。
