Abstract

Because of great harmfulness for greenhouse effect, SF6 gas has to be limited. It is necessary to develop high voltage vacuum circuit breaker to replace SF6 circuit breaker. Insulating structure and arc characteristics of vacuum interrupter are the key. For 72.5kV vacuum interrupter, impulse voltage test is carried to find out factor of effecting on its insulating performance and insulating structure is improved. As a result, a design of 126kV vacuum interrupter is presented and electric field distribution is calculated. Based on statistical property of breakdown in high voltage vacuum interrupter, its voltage withstand capability is analyzed. The relation between arc voltage and arc current, the influence of gap distance on arc noise is measured on 72.5kV vacuum interrupter and the experimental results are analyzed.
