Co2 Circuit Breaker
Abstract
Adopting CO2 as an alternative gas of SF6 in a gaseous
type circuit breaker from the nature point of view, a 72kV-31.5kA
group of CO2 gas circuit breaker model, which does not contain SF6
gas at all, was contrive and produced .In CO2 GCB model, some
powerful technologies for current interruption by CO2 gas were
chosen; namely puffer pressure improve techniques utilizing arc
energy during a current breaking and ablation phenomena of a
polymer component located in the puffer type cylinder. As a effect of
current disruption and electric insulation tests, the CO2 breaker
model carries out practical levels of appearance. Additionally, it was
notice that by taken out a life cycle assessment (LCA) that the CO2
GCB model reduces the global warming impact on an about 40% as
compared with the latest SF6 gas circuit breaker in the same rating
for 2 years operation including one maintenance opportunity.
