用预放电电流法测量SF_6和SF_6/CO_2气体的离子迁移率

用预放电电流法测量了SF_6气体以及SF_6/CO_2混合气体的正负离子迁移率。实验数据表明,正负离子迁移率只是E/p的函数,SF_6/CO_2混合气体的正负离子迁移率随CO_2含量的增加而增大。

The mobilities of negative and positive ions are measured in SF6 gas and SF6/CO2 mixtures by using the pre-dischargc current method. The results show that the mobilities of negative and positive ions are only the simple function of E/p and ion mobility of SF6/CO2 mixtures increase with the incrasing of CO2 content.
