摘　　要：讨论了断路器的选择性保护和限流。提出配电保护应是系统的保护。介绍了配电系统选择性保护的分类和实现的途径,分析了断路器限流在减少短路危害和实现选择性保护中的作用,并讨论了实现限流的方法和限流的分级。Selective protection and current-limiting of circuit breakers were discussed. That the power distribution protection should be whole system protection was indicated. The classification and way of realization of selective protection in power distribution system were introduced. The significance of current-limiting in reducing short-cir- cuit damage and in realizing selective protection was analyzed. The realization and classification of current-limiting were discussed.
