摘　　要：由于现有断路器的开断策略过于复杂,算法设计者不能完全预测算法的执行结果,而将决策树算法应用到智能断路器中,利用C4.5算法对断路器采集的信息进行自动提取知识,根据获得的知识,以最大信息增益率来建立决策树,并进行了简化,能够满足对断路器实时性的要求。The paper analyzed the switch tactic and the deficiency of existing circuit breaker. Decision tree algorithm was applied and the paper explained the decision tree and described C4.5, which is one of the famous algorithms in decision tree. It got knowledge automatically from information collected by circuit breaker and made the decision tree based on the biggest gain ratio of the information attributes, using the creation algorithm of C4.5. The simplified decision-tree has more reasoning efficlency and satisfies the real-time need for circuit breaker.
