Intelligent universal type motor-operating mechanism of breaker

Abstract

The invention discloses an intelligent universal type motor-operating mechanism of a breaker, comprising a bent plate and a ratchet wheel which are arranged on a main shaft, wherein a support tightly matched with the ratchet wheel is arranged corresponding to the ratchet wheel; the support is hinged with one end of a rocker arm; the other end of the rocker arm is hinged with a connecting plate; the connecting plate is connected with a power unit; a neutral gear part lower than the ratchet wheel is arranged on the ratchet wheel; the neutral gear part is a no-toothed structure with a smooth curved surface; and the support is inserted into the neutral gear part when the ratchet wheel is rotated to a set angle. The neutral gear part is arranged on the ratchet wheel of the intelligent universal type motor-operating mechanism of the breaker disclosed by the invention, the accumulation of energy for the breaker is ended, and the support is inserted into the neutral gear part when the ratchet wheel is rotated to the set angle, so that the support is released from the ratchet wheel without providing a special component for pushing the support away; the intelligent universal type motor-operating mechanism of the breaker not only has a simple structure, convenience and rapidness in installation and saved cost, but also has good performance and capability of ensuring one-way operation of the main shaft of the breaker.

Description

technical field [0001] The invention relates to a circuit breaker operating mechanism, in particular to an intelligent universal circuit breaker motor operating mechanism. Background technique [0002] The traditional circuit breaker operating mechanism generally includes a ratchet wheel installed on the main shaft, and a support is provided to cooperate with the ratchet wheel. Circular movement realizes the energy storage of the circuit breaker. When the ratchet rotates to the set angle and the energy storage of the circuit breaker is completed, a control mechanism is required to separate the support from the ratchet, so as to prevent the motor from driving the main shaft to rotate under inertia and damage the circuit breaker. And other operating mechanisms, at present, generally adopt the upper end face of ratchet to arrange control panel, utilize control panel to push away the roof that is installed on the support, thereby realize support and disengagement of ratchet.
