SF6 decomposition Insulated Equipment for 110kv

These decomposition products can indicate PD in GIS, allowing for the PD recognition by analyzing SF6 decomposition products. However, in practical application, it does not allow gas extraction from gas chambers of GIS in service. To simulate the process of SF6 decomposition, an effective simulation assembly was established in the lab.

  • Influence of Micro-oxygen on SF6 Decomposition

    The SF6 chemical property is stable and it is not easy to decompose. However, when insulation defect causes partial discharge (PD) in the equipment, SF6 will decompose and generate low fluorides such as SF2, SF3 and SF4. If there is no other impurities, these low fluorides would reform into SF6 and do not affect the performance of equipment.
