Embodiment
Combine accompanying drawing at present; The utility model is further described, and the name of sequence number is called among the figure: sincere sub 2, the separating brake buckle 3 of output toggle arm 1, lasso 101, locating shaft 102, separating brake, bearing pin 301, separating brake semiaxis 4, separating brake dropout plate 5, reseting pressuring spring 6, support 7, push rod 8, dropout connecting lever 9, separating brake release 10, back-moving spring 11, moving iron core 12, separating brake spacer pin 13, first torsion spring 14, second torsion spring 15, the 3rd torsion spring 16, mount pin 17, left mounting panel 18, right mounting panel 19.
Shown in Fig. 1～4; This operating mechanism Sub-gate release device comprises sincere sub 2, the separating brake buckle 3 of left mounting panel 18, right mounting panel 19, output toggle arm 1, separating brake, separating brake semiaxis 4, separating brake dropout plate 5, push rod component, dropout connecting lever 9, separating brake release 10; Wherein push rod component is made up of push rod 8, support 7, reseting pressuring spring 6; Support is fixedly connected left mounting panel lateral surface, and the spacing slip of push rod socket reseting pressuring spring level places in the support, and the push rod two ends are exposed to support; The separating brake release is made up of housing, coil, back-moving spring 11, moving iron core 12, and coil places in the housing, and housing is fixed in left mounting panel lateral surface, and moving iron core socket back-moving spring slides and places in the coil, and moving iron core lower end is limited in housing bottom.This Sub-gate release device concrete structure is: the output toggle arm middle part is through the left and right mounting panel of locating shaft 102 movable connections of disjunctor; Output toggle arm one end connects lasso 101 through pin; One end activity of this lasso and the sincere son of separating brake offsets; The sincere son of separating brake is articulated in separating brake buckle middle part, and separating brake buckle bottom is provided with the bearing pin 301 of disjunctor, through the left and right mounting panel of the movable connection of this bearing pin; And be connected first torsion spring 14 between bearing pin and the left mounting panel, left mounting panel is provided with and the spacing separating brake spacer pin 13 that connects of bearing pin; The axial region of separating brake buckle top and separating brake semiaxis offsets; The left and right mounting panel of the movable connection in separating brake semiaxis two ends; The end that the separating brake semiaxis passes left mounting panel connects separating brake dropout plate through second torsion spring 15, and the push rod one end activity of separating brake dropout plate and bracket component offsets, and an end activity of the push rod other end and dropout connecting lever offsets; The dropout connecting lever is through mount pin, the left mounting panel of the 3rd torsion spring 16 movable connections, and the moving iron core bottom activity of the dropout connecting lever other end and separating brake release offsets.Above-mentioned activity offsets; Be that finger offsets in motion process; That is: when coil drove moving iron core and moves downward, moving iron core bottom offseted with an end of dropout connecting lever, and the dropout connecting lever offsets with an end of push rod in rotation process; When push rod slided left in support, push rod and separating brake dropout plate offseted.Said structure is the concrete structure of the utility model.
Combine said structure at present, the operation principle of the utility model be described further:
At first, mechanism closes a floodgate, and under the switching force effect of circuit breaker, output toggle arm 1 is rotated counterclockwise, and output toggle arm drives sincere sub 2, the separating brake buckle 3 of separating brake and rotates accordingly, and separating brake buckle and separating brake semiaxis 4 interlock, and promptly accomplish making process.During separating brake, at first give the coil electricity of separating brake release 10, make moving iron core 12 in the coil overcome the elastic force of back-moving spring 11 and move downward; One end of moving iron core lower end and dropout connecting lever 9 offsets; And promote the dropout connecting lever and overcome the elastic force of the 3rd torsion spring 16 and rotate counterclockwise, the dropout connecting lever other end offsets with push rod 8 right-hand members of push rod component in rotation process, and promotes push rod and slide; The push rod other end offsets with separating brake dropout plate 5 in sliding process; And promote the rotation of separating brake dropout plate, and separating brake dropout plate drives separating brake semiaxis 4 through second torsion spring 15 and rotates, and the separating brake semiaxis is removed the state that interlocks between separating brake semiaxis and the separating brake buckle in rotation process; The separating brake buckle clockwise rotates under the effect of first torsion spring 14, and output toggle arm is realized separating brake under the effect of separating brake power.When the coil blackout of separating brake release; Moving iron core automatically resets under the effect of back-moving spring; Corresponding dropout connecting lever, push rod, separating brake dropout plate reset under the effect of the 3rd torsion spring, reseting pressuring spring, second torsion spring respectively; The rotation that also resets accordingly of separating brake semiaxis drives separating brake buckle, the sincere sub-spinning reduction of separating brake, and output toggle arm keeps gate-dividing state.More than be the separating brake process; Opening time is meant when coil and gets the electric spent time of whole process that mechanism's separating brake puts in place behind the coil losing electricity; Through increasing intermediate link and push rod, opening time is obviously increased, thereby the circuit breaker break performance is improved to the distance of separating brake dropout plate.
