Electromagnetic Compatibility Design of Intelligent Circuit Breaker

The work environment of control unit is not very well for intelligent circuit breaker, such as electromagnetic interference is one important factor. In this paper, hardware and software were applied as anti-Interference measures to ensure the Electromagnetic Compatibility (EMC), so the reliability of circuit breaker system was advanced. The external and internal interference was defined depressed by hardware, and software was an important complement. The design result was proved that it meets intelligent control protection and embedded network real-time communications.
