| Abstract: | A new dual-breaker air circuit breaker(ACB)was proposed.With two simplified model suffering the effect of short circuit current,the dynamic repulsion force acted on contact in ACB with single and double breakers were analyzed and compared.The reason that dual-breaker configuration had higher dynamic stability was explained as well.The key design of ACB is to improve the mechanical strength of operation mechanism. |
