Abstract

The invention discloses a circuit breaker tripping structure. The circuit breaker tripping structure comprises a tripping driving part and a tripping rotating part; the tripping driving part and the tripping rotating part are both provided with shaft holes and have the same axis, and the tripping driving part is movably connected with the tripping rotating part through a fixing shaft; the tripping driving part extends in the axial direction to be provided with a first shaft sleeve, and one side of the first shaft sleeve extends in the transverse direction to be provided with a driving rod; the other side of the tripping driving part and the first shaft sleeve jointly extend in the transverse direction to be provided with a first clamping part and a second clamping part; the tripping rotating part extends in the transverse direction to be provided with a platform, the platform is provided with a rotating rod in the axial direction, and the rotating rod is embedded between the first clamping part and the second clamping part; the tripping rotating part comprises a rotating portion, the rotating portion is provided with a connecting shaft in the axial direction, the connecting shaft is provided with a connecting shaft sleeve which is connected to the connecting shaft in a sleeving mode, and the connecting shaft sleeve is connected with the platform. The circuit breaker tripping structure can enable a circuit breaker to be quickly tripped and not be switched on through a handle.

Description

technical field [0001] The invention relates to the technical field of electrical switches, in particular to a circuit breaker tripping structure. Background technique [0002] Miniature circuit breaker, referred to as MCB, is the most widely used terminal protection device in electrical terminal distribution devices. It is used for single-phase and three-phase short-circuit and overload protection below 125A, including single-pole 1P, two-pole 2P, Three-pole 3P, four-pole 4P. The circuit breaker tripping structure is used to control the rapid tripping of the circuit breaker at a long distance, and the circuit breaker tripping structure usually adopts an electromagnet operating mechanism. The motor operating mechanism is used to operate the opening and closing of the circuit breaker. The closing and opening are achieved by the position of the cam inside the electric operating mechanism. When the circuit breaker is operated by the electric mechanism, it can ensure that the c...
