High voltage abb sf6 gas breakers
WebThe main reason for gas monitoring is to make sure there is enough SF6 gas to run the machinery. In most cases, this requires checking the gas density. However, there are caveats to measuring gas densities. One spot in the GIS system is often used to assess gas density, and that spot is the enclosure. (Figure 1). WebIt is used for arc quenching in high voltage circuit breakers up to 800 kV in power stations, electrical grids etc. SF6 gas has very high electronegativity. It has a strong tendency to absorb free electrons. When an arc is struck between the contacts, it absorbs the free electrons from it.
