Abstract
The aims are to develop new kinds of insulating mediums being technically as well as economically attractive and fully understand the electronegative gas characteristic of endurance voltages, mechanism of partial discharge and widen their using areas in the high voltage system experiments. The article presents the experiment procedures, contents are involved in as follow: point-plane, point-point, co-axial cylindrical and co-centric sphere electrode systems, and industrial purity SF/sub 6/ and its mixture combining N/sub 2/ are filled into the experiment chamber in different partial pressure and applied the AC and impulse voltages in different pressures. The mechanism of initiated PD potentials and breakdown of the SF/sub 6/ and SF/sub 6//N/sub 2/ have been analyzed theoretically according to the molecular structure and physical characteristics of the electro-negative vases, the research works are helpful to develop and widen using fields of the SF/sub 6/ and its mixtures in high voltage engineering.
