Abstract

The invention discloses an electrodynamic type intelligent breaker, wherein an electrodynamic type operating mechanism is arranged on a cover; the mechanism comprises a motor, a transmission mechanism driven by the motor, and a one-way clutch mechanism; the one-way clutch mechanism comprises clutch ratchets relatively fixedly arranged on an output shaft, a driving board provided with a round clutch hole, and a clutch piece for driving the driving board to rotate under the action of the clutch ratchets; a plurality of clutch ratchets are uniformly arranged on the periphery of an eccentric ratchets; one end face of each clutch ratchet is a driving face, and the other end face is an arc-shaped slide face; the eccentric ratchet is arranged in the round clutch hole of the driving board; both sides of the driving board are respectively provided with a limit hole communicated with the clutch hole, and the arrangement direction of the limit hole is perpendicular to the clutch hole; the clutch piece is a clipping reed provided with a gap; and reed bodies arranged on both ends of the gap are inserted into the limit hole of the driving board and clipped on the clutch ratchets at the two opposite side ends of the clutch ratchet. The invention has the advantages of good reliability, difficult damage and lower cost.

Description

technical field [0001] The invention belongs to the technical field of circuit breaker structure design, and in particular relates to an electric intelligent circuit breaker. Background technique [0002] Leakage circuit breaker is a circuit breaker that can automatically disconnect the circuit when the residual current reaches or exceeds the specified value under specified conditions, and is used to prevent personal injury, equipment damage, fire and other accidents caused by electric shock and leakage. [0003] In addition to the traditional leakage circuit breaker can complete the function of automatic opening when the leakage or overload exceeds the preset value, manual operation is required to achieve opening or closing at other times. For example, a leakage circuit breaker disclosed in Chinese patent 200620105204.2 is equipped with an arc extinguisher, contacts, leakage release, overcurrent release, soft connection copper wire, current transformer, and zero-sequence cu...
