Experimental Research on Endurance Behaviors of the SF6/N2 Mixtures under Impulse Voltage
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. The article presents the experiment procedures, contents are involved in as follow: needle-needle, needleplane, sphere-plane, sphere-sphere and needle-sphere electrode systems, and industrial purity SFt and its mixture combining N2 are filled into the experiment chamber in different partial pressure and applied the impulse voltages in different pressures. The mechanism of initiated PD potentials and breakdown of the SF6and SF6/N2 have been analyzed theoretically according to the molecular structure and physical characteristics of the electro-negative gases, the research works are helpful to develop and widen using fields of the SF6and its mixtures in high voltage engineering.
SF6/N2 impulse voltage synergistic effect electro-negative gas.
