Abstract

The invention discloses an electric operation mechanism for a frame type circuit breaker. The mechanism comprises a motor, a speed reduction gear set, a side plate, a portal support, a first shaft, a second shaft, a spring, a torsion spring, a pawl, a backstop spring, a backstop pawl, a roller, a cam and a ratchet of which partial surface is not provided with teeth, wherein the portal support consists of a support, a connecting rod, a rivet and two third shafts; the rivet is riveted on the connecting rod; the support is sleeved on the rivet and the two third shafts; one end of the spring is hooked on a speed reduction gear set shaft, and the other end of the spring is hooked on the connecting rod of the portal support; the motor, the speed reduction gear set, the first shaft and the second shaft are arranged on the side plate; an input gear of the speed reduction gear set is driven by a motor main shaft; an output gear and the cam of the speed reduction gear set are sleeved on the first shaft; the backstop spring and the backstop pawl are sleeved on the second shaft; the pawl and the roller are sleeved on the third shaft respectively, and the roller is pressed against the cam; the torsion spring is sleeved on the rivet, and one end of the torsion spring is pressed against the pawl; the ratchet is supported on the side plate in a rotatable way; and the pawl and the backstop pawl are engaged with the ratchet. The mechanism has the advantages of simple structure, long service life and capability of realizing unidirectional movement of the main shaft.

Description

technical field [0001] The invention belongs to the structural design field of circuit breakers. Specifically, it relates to an electric operating mechanism of a frame type circuit breaker. It is used for stored energy operating mechanism of frame type circuit breaker. Background technique [0002] At present, the energy storage operating mechanism of the frame circuit breaker mainly has the disadvantages of complex structure, poor reliability, and high energy consumption. The most important thing is that it is difficult to realize the unidirectional movement of the main shaft. Contents of the invention [0003] The purpose of the present invention is to provide a frame-type circuit device electric operating mechanism with simple structure, long service life and unidirectional movement of the main shaft. [0004] The technical solution to achieve the above purpose is: an electric operating mechanism of a frame type circuit breaker, which includes a motor, a reduction ge...
