摘　　要：分析了现有断路器的分断策略及不足,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。用决策树表示的知识具有更高的推理效率,能够满足对断路器实时性的要求。The switch tactic and its deficiency of the circuit breaker was analyzed. The decision tree algorithm was applied in this article. The decision tree was explained and C4, 5 was described in detail, 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 efficiency and satisfies the real-time of the circuit breaker.
