Based on the analysis of the structural characteristics and working principle of the mono-stable permanent magnet （PM） vacuum circuit breaker, the overall structure design of intelligent control module for the PM vacuum circuit breaker was studied by integrating with the microprocessor, electrical apparatus and communication technologies. The hardware structures and communication principles of the Modbus and Profibus-DP fieldbus communications for low voltage intelligent PM vacuum circuit breaker were investigated. The communication command format and software system design were discussed respectively. As a result, the optional remote communication, monitoring and control technology of intelligent PM vacuum circuit breaker are achieved, which is of great value in engineering application for improving the overall supply level, the degree of automation and security of the smart grid.
