The electric operating mechanism of a circuit breaker comprises a transmission main shaft, wherein a main gear is arranged on the transmission main shaft, the inner ring of the main gear is matched with the transmission main shaft through a ratchet wheel structure, and a speed changing mechanism is arranged between the main gear and the power output shaft of a driving motor for transmission; the lower end of the transmission main shaft is fixedly connected with a crank, the shaft pin of the outer end of the crank is cooperatively connected with a sliding block through a roller, the sliding block is limited to a linear guide way and the sliding block is provided with a push rod used for poking the operating handle of the circuit breaker. The utility model has the advantages of compact structure, small size, simple transmission mode, convenient operation and high reliability and response speed of operating action.
Description
Technical field
The utility model belongs to the voltage switch equipment technical field, relates to a kind of electric operating mechanism of circuit-breaker.
Background technology
Traditional electric operating mechanism of circuit-breaker is general to adopt two axles to connect motor-operating mechanism and manual-operating mechanism respectively, add parts such as cam, slide block are arranged in addition, after electric operating is carried out disjunction, closed procedure, can't keep therebetween fitting, so that next electric operating all can have impact, vibration, influences service life of equipment and reliability.The transmission device that at present newer motor-operating mechanism adopts improves to some extent to this, with electric operating and the shared power transmission shaft of manual operation, has avoided the appearance of subproblem.But existing this class formation still exists defectives such as power transmission shaft and clutch part complex structure, technological requirement height, volume be big, has limited its application in switch cubicle; The motor-operating mechanism of existing structure is in running simultaneously, and the position indicating mode of " combined floodgate " " separating brake " " dropout " is obvious inadequately, has also influenced its reliability of operation.
Summary of the invention
Technical problem to be solved in the utility model is, the electric operating mechanism of circuit-breaker of a kind of simple and compact for structure, reliable in action height, convenient operation and control is provided.
Electric operating mechanism of circuit-breaker of the present utility model includes a transmission main shaft, a master gear is installed on the transmission main shaft, cooperate by ratchet structure between the inner ring of master gear and the transmission main shaft, between the power output shaft of master gear and drive motors by the gear transmission; The upper end of transmission main shaft connects the manual operation handle, the lower end of transmission main shaft is fixedly connected with a crank, the pivot pin of crank outer end is connected by a roller and a slide block, this slide block is limited on the line slideway, it can move back and forth at the drive lower edge of crank guide rail, and slide block is provided with the push rod that is used for stirring the breaker operator handle.In addition, slide block also can be fixedlyed connected with an indicating piece, segmentation scribbles three kinds of colors on the indicating piece, be used for indicating combined floodgate, dropout, three kinds of states of separating brake, indicating piece places the rear side of a panel, then has the indicator hole that is used for observing marker color on the correspondence position of panel, when indicating piece moves with slide block, make the section of different colours relative with indicator hole, the operator can judge the residing state of circuit breaker by the color that indicates in the indicator hole like this.
The utility model compact conformation, volume are little, are convenient to settle in switch cubicle, and its kind of drive reliability and reaction speed simple, easy and simple to handle, operational motion also is improved simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a ratchet structure fit structure schematic diagram between transmission main shaft and the master gear;
Fig. 3 is the installation site schematic diagram of indicating piece and indicator hole.
Embodiment
As shown in Figure 1, the transmission main shaft 1 of electric operating mechanism of circuit-breaker of the present utility model can be driven by gear shift 4 and master gear 2 by the power output shaft 3 of drive motors, also can be driven by the manual operation handle 5 of transmission main shaft upper end.The rotation of transmission main shaft can move back and forth along line slideway 9 by the crank 6 and the roller 7 drive slide blocks 8 of its lower end.The moving of slide block then stirred breaker operator handle 11 by push rod 10 and to realize the separating brake of circuit breaker, combined floodgate etc.
As shown in Figure 2, cooperate by ratchet structure between transmission main shaft 1 and the master gear 2, promptly transmission main shaft is provided with the backing pin 12 of expandable, and at the master gear inner ring ratchet 13 is set.When master gear clockwise rotated under motor-driven, the step in ratchet front promoted backing pin, and transmission main shaft is together clockwise rotated, and realized electric operating; When the needs manual operation, directly twist transmission main shaft by the manual operation handle and clockwise rotate, the backing pin on the main shaft slides on the curve at the ratchet back side, stretches, and is not blocked.
As shown in Figure 3, the moving of slide block 8 can drive an indicating piece 14 and to move, and segmentation scribbles red, white, green three kinds of colors on the indicating piece, and it is corresponding with the indicator hole 16 on the panel 15, can mark combined floodgate, dropout and three kinds of states of separating brake respectively.
