Adopting CO2 as an alternative gas of SF6 in a gas circuit breaker from the environmental viewpoint, a 72kV-31.5kA class CO2 gas circuit breaker (CO2-GCB) model, which does not contain SF6 gas at all, was designed, and produced. In the CO2-GCB model, some effective technologies for current interruption by CO2 gas were adopted; namely, puffer pressure enhancing techniques utilizing arc energy during a current interruption and ablation phenomena of a polymer element located in the puffer cylinder. As a result of current interruption and electric insulation tests, the CO2-GCB model achieved practical levels of performance. Furthermore, it was found by carrying out a life cycle assessment (LCA) that the CO2-GCB model could reduce the global warming impact by about 40% compared to the latest SF6 gas circuit breaker in the same rating for 20 years operation including one maintenance opportunity.
