Then the intellectual control technology of vacuum circuit breaker is discussed particularly. As a control object, the bi-stable permanent magnetic actuator is separated into basic principle so as to determine the nature of the whole. The direct-coupled models of magnetic fields for analysis and for calculation are presented. The static and dynamic characteristics of the models and dynamic behavior analysis and matching analysis for the vacuum circuit breaker with bi-stable permanent magnetic actuator are also discussed. For a further study, fuzzy neural network control technology based on synchronized-closing operation of vacuum circuit breaker is analyzed and the research conclusion is used for realizing the synchronized-closing of vacuum circuit breaker in the future.
