| 摘要 | An intelligent magnetic-latching miniature circuit breaker comprising a housing, a magnetic-latching relay, and a driver circuit. The driver circuit receives a control signal and then drives the magnetic-latching relay to act. The magnetic-latching relay comprises a dynamic spring assembly, a static spring assembly, a lever, a push piece, and a magnetic steel assembly. When the magnetic steel assembly rotates, the lever moves and then the push piece closes or opens the contacts of the dynamic spring assembly or the static spring assembly. The invention is also provided with a central processing unit, a communication chip, a mutual inductance module, and a current-regulating circuit. The mutual inductance module is disposed on an extension wire of the dynamic spring assembly; the current-regulating circuit is connected to the central processor and the mutual inductance module; and the central processing unit drives the magnetic-latching relay by means of the driver circuit and in accordance with a current-state signal transmitted by the current-regulating circuit, thus achieving overload protection. | ||||||
