  • sf6 Gas Mixture Recovery of Polluted

    SF6 Gas Recovery from SF6 / N2 Mixtures Using Polymer. Abstract. SF 6 gas recovery is considered one of the most important issues when we utilize a gas mixture at a low SF 6 content in gas insulation 1).One of the plausible methods is to recover SF 6 as liquid using the difference in boiling point between gas species in the mixture.

  • Thermal Decomposition Properties of Epoxy Resin in SF6/N2 Mixture

    As a promising alternative for pure SF 6, the mixture of SF 6 /N 2 appears to be more economic and environment-friendly on the premise of maintaining similar dielectric properties with pure SF 6. But less attention has been paid to the thermal properties of an SF 6 /N 2 mixture, especially with insulation materials overheating happening simultaneously.

  • Characteristics of Partial Discharges on a Dielectric Surface

    This paper presents the results of a recent investigation of pulsating PD phenomena occurring in point-dielectric gaps under an alternating voltage in SF 6-N 2 mixtures. The dielectric is a cast epoxy resin with Al 2 O 3 filler. A computer-based PD recording system has been utilized which captures the amplitudes and time of occurrences of all pulsating PD events above a certain amplitude within an arbitrary time period.
