SF6替代气体与空气混合的绝缘性能研究OA北大核心CSCDCSTPCD
Study on the Insulation Properties of the Mixture of SF6 Substitute Gas and Air
CF3I和c-C4F8作为目前研究最多的SF6替代气体, 需要与缓冲气体混合以降低液化温度.为了评估使用空气作为SF6替代气体缓冲气体的可能性, 通过求解两项近似的Boltzmann方程, 计算了CF3I/空气、c-C4F8/空气混合气体的电子崩参数.首先, 分别计算了CF3I/空气、c-C4F8/空气混合气体的约化电离系数、约化附着系数、约化有效电离系数、约化临界场强, 以及表征对不均匀电场敏感程度的c值 (约化有效电离系数关于约化电场的关系曲…查看全部>>
As the most studied SF6 substitute gas, CF3I and c-C4F8 need to be mixed with buffer gases to reduce liquefaction temperature. For the purpose to assess the possibility for air to be buffer gas in SF6 substitute gas, electrons warm parameters of CF3I/air and c-C4F8/air are calculated through two-term approximated Boltzmann equation. First, the reduced ionization coefficient, reduced attachment coefficient, reduced effective ionization coefficient, limiting r…查看全部>>
