摘　　要：该设计主要针对电力系统输配电线路中带时限电流速断保护的问题,采用微电子、微处理器以及CAN总线接口技术,设计出的交流继电器不仅可以独立实现单点的限时速切的保护功能,还可利用通信接口把相关的继电器作为网络节点连接到CAN总线上,通过总线和上位PC机进行双向通信,从而利用上位PC机来实现对工作节点全局的控制.This design mainly aims at the problem of time-limited rapid action Protection in electric transmission and supply system. We use the micro-electronics, micro-controller and CAN bus to develop a small AC delay. This delay can not only solve the above problem by itself but also connect with CAN bus as node through its interface. By using of communication through CAN bus, we can realize the control of the whole system by control PC.
