Abstract
Vacuum circuit breaker becomes more and more complicated, integrated, high-speed and intellectualized. To insure vacuum circuit breaker in its good conditions, the function of fault diagnosis gets more important than before in the process of repairing. This paper is addressed a modelbased fault detection framework for vacuum circuit breaker by trip coil analysis. At first, the electromagnetic model of the trip coil is built. Secondly, algorithm of abrupt changes detection and dynamic time warping algorithm is introduced. At last, value comparison between the similarity and the threshold concludes whether a fault has occurred or the trip coil has potentially hazardous effects. The experimental results show that this method is effective.
