Abstract

In this paper, we propose a new "Intelligent Operation" concept for high voltage SF6 gas circuit breakers, in which the moving contacts are self-adaptively controlled from one position to an adjacent position to optimize the circuit breaker performance. To analyze and design the operation, a new model of high voltage SF6 gas circuit breaker is developed, and the moving characteristics of the new type circuit breaker are computed based on the new model. Then both the mechanical and electrical wears are quantitatively analyzed according to the breaker's new moving characteristic. Finally, we demonstrate the reliability improvement of the new type of high voltage SF6 gas circuit breaker.
