In view of the present problem that low voltage miniature circuit breaker can"t remotely switch, we design a kind of intelligent motor type miniature circuit breaker control system. This paper introduces the necessity designing the control system, puts forward the overall design scheme and design principle of control system, we study and implement the system key techniques such as low power consumption MCU control design and the standby power supply design, etc. the control flow, state detection and feedback process of the system are briefly explained. Functional verification test shows that the intelligent miniature circuit breaker control system completely conforms to the requirements of the domestic relevant standards, can completely achieve the points switching control and state feedback functions, and has great application value and promotional value.
