Abstract :
Based on the analysis of the existing current protection model, a reverse time limit current protection model according to the temperature rise has been put forward. The feasibility and wide application of the proposed current protection model have been verified by testing and analyzing the experimental results of the vacuum circuit breaker assembled with the permanent magnetic actuator.
