摘要

based on the analysis of normal load breaking's peculiarity, the dynamic interrupting characteristic and dielectric recovery characteristic of high voltage SF_6 puffer breaker are simulated during breaking normal load current. Result indicates that there exist more surpluses on interrupting capacity when breaking rated current. Employing the method of simulating the arcing time window, combined with the circuit breaker "Intelligent Operation" theory, the necessary minimum opening velocity is obtained.
