摘　　要：智能断路器是在传统断路器中引入计算机技术、数字处理技术和通信技术而形成的新一代断路器.本文采用TI公司的MSP430处理器芯片,完成了智能断路器控制器的设计.该智能断路器控制器不仅具备基本的三段电流保护功能,还具有液晶显示、热记忆、自诊断等功能;另外,为实现电力配电网络的通信要求,本断路器控制器采用Controller Area Net-work(CAN)现场总线技术实现控制信息的远程传输.实验结果表明,所设计控制器不仅实时性好,电磁兼容性强,而且体积小、成本低、易于实现.Intelligent circuit breaker is a new sort of circuit breakers, which involves computer technology, digital processing technology, and communication technology. The design of intelligent circuit breaker controller is completed by using the MSP430 MCU of TI company. Besides three kinds of basic safeguard functions, the intelligent circuit breaker controller has the characteristics of LCD display, heat-memory and self-diagnosis. In addition, in order to realize the communication requirement of the electric power distribution networks, Controller Area Network （CAN） bus is applied in the circuit breaker controller to transfer the control information at a distance. The experiment shows that the designed controller has the characteristics of good real-time, high EMC, small volume, low cost and simple implementation.
