Abstract

The invention relates to an electric operation mechanism with in-place separation and reunion and unidirectional transmission functions. The electric operation mechanism comprises a machine frame. The machine frame is provided with a motor and a reduction gear mechanism. The machine frame is further provided with a working gear. The upper end surface of the working gear is provided with a ratchet wheel. The ratchet wheel and the working gear are coaxially arranged, and the ratchet wheel and the working gear can rotate relatively. The outer end of the ratchet wheel is provided with a clamping port. The working gear arranged at the outer side of the ratchet wheel is provided with a pawl. The middle part of the pawl is rotationally arranged on the working gear through a hinge pin. The inner end of the pawl and the clamping port on the ratchet wheel are matched to drive the unidirectional rotation of the ratchet wheel. A support at the outer side of the hinge pin is provided with a stop pin. When the pawl clockwise rotates along with the working gear, the pawl rotates to enable that the outer end of the pawl is abutted against the stop pin, and the pawl continuously rotates along with the working gear; when a main shaft reaches a preset position, the main shaft drives the inner end of the pawl to move outwards, the pawl and the ratchet wheel separate, and at the position, the working gear rotates without driving the rotation of the ratchet wheel, and the main shaft can rotate freely within a certain angle.

Description

technical field [0001] The invention relates to an electric operating mechanism with in-position clutch and one-way transmission functions. Background technique [0002] At present, the electric operating mechanism of the existing medium-voltage circuit breaker can only provide power, specifically, only the motor and the reduction system. The operation and control structure of the electric operating mechanism is placed in the manual operating mechanism, in other words. Limited by the inherent structure and size of the manual operating mechanism, the operation and control structure is complex in structure, large in size, high in cost, and high in energy consumption. In order to optimize the manual operating mechanism, reduce costs, and realize the modularization of manual and electric operations, the operation and control structure of the electric operating mechanism in the manual operating mechanism is optimized into the electric operating mechanism module.
