Modelling of flaky particle motion under typical vibration excitation for gas insulated switchgear live operation

open access: yesHigh Voltage, Volume 10, Issue 3, Page 660-672, June 2025.
Abstract Within 30 min after live operation of gas‐insulated switchgear (GIS), more than 60% of discharge failures are caused by metallic particles. To address this issue, this study explored the vibration propagation mechanisms in GIS cavities and established an equivalent vibration transmission model.

Temperature rise characteristics of C5F10O/CO2 gas mixture AC high voltage switch bus

open access: yesHigh Voltage, Volume 10, Issue 2, Page 325-336, April 2025.
Abstract C5F10O/CO2 gas mixture is one of the most promising alternatives to SF6 as an insulating gas in high‐voltage switchgear. As a key performance index in product design, the temperature rise characteristics are rarely reported. In this paper, the thermodynamic parameters of C5F10O/CO2 gas mixture were calculated first. Then, the calculation model
