Abstract: Aiming at the problem that the intelligent micro-circuit breaker is prone to misoperation and miss trip under strong magnetic interference, the intelligent micro-circuit breaker control system, DC motor, switching power supply and other related modules that may cause magnetic interference are analyzed, and the concrete optimization design scheme is put forward. An optimum design method for anti-magnetic interference of control system based on dual-mode detection of micro-switch and Hall switch is proposed, which is realized in both hardware and software. The optimum design methods for anti-magnetic interference of DC motor and switching power supply output power are also proposed, which improve the anti-magnetic interference ability of DC motor and switching power supply. The experimental results show that the optimized intelligent micro-circuit breaker has excellent anti-magnetic interference performance, high stability and reliability. It thoroughly solves the problem that the intelligent micro-circuit breaker is prone to maloperation and rejection under strong magnetic interference, and has a strong application value.
