  • End of life estimation of HV switchgear and GIS substations

    A service life of 50 years for GIS of the first and second generation is readily achievable for GIS with hitherto acceptable reliability, if a few measures for lifetime extension are introduced: Replacement of cast resin insulated voltage transformer, if any, by SF6 film insulated transformer.

  • Panel discussion: The pros and cons of using SF6 gas in

    SF 6 gas is considered as a greenhouse gas, consequently release of the gas into the atmospheres should be minimised or avoided. At the end of switchgear life, the gas should be recycled and switchgears should be designed to ensure leaks are minimised as far as possible. Appropriate designs are required for easy filling and collection.

  • Interaction Mechanism between the C4F7N–CO2 Gas Mixture and

    C4F7N (fluorinated nitrile) has been introduced as a remarkable substitute gas for the greenhouse gas SF6 (sulfur hexafluoride) which is used in gas-insulated equipment (GIE). Intensive investigations about the compatibility between C4F7N and materials used in GIE are required to decide their long-term behavior. In this paper, the interaction mechanism between EPDM, used as a sealing ring in

  • A review on SF6 substitute gases and research status of CF3I

    Nov 01, 2018 · SF 6 gas is considered as one of the most harmful kinds of atmospheric greenhouse gases (Xiaoxing et al., 2013b). Its global warming potential (GWP) is 23,900 times higher than that of CO 2, and the life span of this gas is 3400 years in the atmosphere (Xiaoxing et al., 2013b). Global warming, ozone depletion, and drastic reduction of biological species are known as the three major environmental problems.

  • Influence of Oxygen on the Thermal Decomposition Properties

    The C4F7N (fluorinated nitrile) gas mixture has been recognized as the most potential substitute gas to SF6 used in gas-insulated equipment. In this paper, we explored the thermal stability and decomposition properties of the C4F7N–N2–O2 gas mixture. The influence mechanism of oxygen content and temperature on the byproduct generation was obtained and analyzed. It was found that thermal
