Abstract
A full size model gas circuit breaker without puffer has been built and tested based on a new arc quenching principle of self-flow generation. The breaker generates the flow around current zero due to the pressure rise in the cylinder by positive utilization of nozzle clogging phenomenon. The test was carried out on BTF and SLF conditions prescribed in IEC standards. The breaker successfully interrupted 40 kA for BTF and SLF respectively at 84 kV. Based on the test results and the theoretical analysis of the self-flow generating behavior, it is remarked that the new arc quenching principle is more effective to get higher fault clearing capability compared with the puffer principle.Keywords
