SF6 Breakers process for KEPCO

SF6 Breakers process for KEPCO

Breakers that use carbon dioxide as the insulating and arc extinguishing medium work on the same principles as a sulfur hexafluoride (sf 6) breaker. Because sf6 is a greenhouse gas more potent than CO 2, by switching from sf 6 to CO 2 it is possible to reduce the greenhouse gas emissions by 10 tons during the product lifecycle.

  • An SF6 purification process utilizing gas hydrate

    Jun 15, 2019KEPCO (Korea Electric Power Corporation) is known to use SF 6 as insulation material for 22.9 kV GIS (Gas Insulated Switchgear) and buses. Each equipment contains several liters to several tens of liters of SF 6 gas. GIS, circuit breakers, and buses have service life of about 22 years.Cited by: 6

  • Status of SF6 separation/refining technology development

    Jul 12, 2018This method is the most recent technology being developed by KEPCO. Considering the characteristics of SF 6 hydrate formation/dissociation reaction, this method is suited to process relatively low purity SF 6 of 70% or below and developed accordingly. The recovery rate is not available since the system was not vented during the semi-continuous operation.Cited by: 9
