Abstract
The utility model relates to a mechanical interlocking mechanism of an automatic transfer switch electric appliance. The mechanical interlocking mechanism comprises a mechanism plate 1 for an operating mechanism. A left guide column 3 and a right guide column 4 are arranged on both sides of the mechanism plate. A left guide column 2 of which the inside is provided with an inclined chamfer and a right guide plate 5 are driven by a driving shaft 11 of a driving mechanism 10 which rotates around a rotating shaft 17, and can respectively do linear sliding along the left guide column 3 and the right guide column 4. The lower ends of the left guide column 2 and the right guide column 5 are respectively provided with a guide-in curve 6 and a guide-in curve 7 which respectively extend out of the inside surface. A fan-shaped sheet 4 which can rotate around a self-locking shaft 3 is arranged between the left guide column 2 and the right guide column 5. The mechanism enables the left guide plate and the right guide plate to make a circuit breaker trip in the closing position, and the shaft of the driving mechanism can enter the guide-in curves 6 and 7 at the lower ends of the left guide column 2 and the right guide column 5, and then drive the left guide plate and the right guide plate to drive the tripped circuit breaker to return.
Description
Technical field:
The utility model patent relates to a kind of mechanical interlock mechanism, particularly a kind of mechanical self-latching mechanism that is used for automatic transfer switching electric appliance.
Background technology:
Known automatic transfer switching electric appliance generally is to adopt two motor-operating mechanisms or a cover switching device shifter to control two to carry out circuit breakers and carry out separating brake, close a floodgate and switch, and great majority are carried out circuit breakers and had function at separating brake position trip free.Carry out the circuit breakers power supply of closing a floodgate simultaneously for avoiding occurring two, must dispose interlocking device.Though the interlocking device of the automatic transfer switching electric appliance of technology employing at present can realize preventing to carry out circuit breaker dropout automatically reset requirement in back when closing a floodgate, but in case when carrying out circuit breaker, thread off at gate-dividing state, the execution circuit breaker is automatically reset, must pull the execution circuit breaker handle with hand it is resetted.So just make troubles to use, fail safe also can't effectively ensure.
Summary of the invention:
Problem in view of the interlocking device of above-mentioned prior art automatic transfer switching electric appliance.It is a kind of reliable and stable that the purpose of the utility model patent is to provide, and threads off when carrying out circuit breaker in the separating brake position, all can make to carry out the automatically reset mechanical self-latching of circuit breaker mechanism.
The utility model patent adopts following technical scheme to realize:
The mechanical interlock mechanism of this automatic transfer switching electric appliance, comprise the mechanism's plate 1 that is used for operating mechanism, both sides are provided with left guide pillar 3 right guide pillars 4 on mechanism's plate, the inboard has the left guide plate 2 of chamfer to be subjected to around the shaft with right guide plate 5, and the driving shaft 11 of the driving mechanism 10 of 17 rotations drives, can make linear slide along left guide pillar 3 right guide pillars 4 respectively, left side guide plate 2 has the importing curve 6 that grows medial surface to import curve 7 respectively with right guide plate 5 lower ends, the centre of left side guide plate 2 and right guide plate 5 is provided with can be around self-locking shaft 3 rotating fanning strips 4: the execution circuit breaker was threaded off when this mechanism can realize left guide plate and right guide plate in the separating brake position, the axle of driving mechanism all can enter the importing curve 6 of left guide plate 2 and right guide plate 5 lower ends, 7, drive the execution reset of breaker of threading off thereby drive left and right sides guide plate.
Description of drawings:
Fig. 1 is the operating position plane graph of mechanical interlock mechanism of the automatic transfer switching electric appliance of the utility model patent.
Fig. 2 is the detail drawing of mechanical interlock mechanism left and right sides guide plate of the automatic transfer switching electric appliance of the utility model patent.
Code name implication among the figure: 1. 13. left guide plate inboards, mechanism's plate 2. left guide plate 3. left guide pillar 4. right guide pillar 5. right guide plate 6. left guide plates importing curve 7. right guide plates importing curve 8. self-locking shafts, 9. fanning strips 10. driving mechanisms, 11. driving shafts inboard chamfering inclined-planes of 12. left guide plates are faced 15. right guide plate inboards, the inboard chamfering inclined-plane of 14. right guide plates directly and are faced 16. fanning strip left surfaces, 17. fanning strip right flanks directly
Embodiment:
As Fig. 1 (a) when the execution circuit breaker of left guide plate 2 operations is threaded off in diagram separating brake position, the influence that left side guide plate 2 is carried out circuit breaker tripping power can move upward, at this moment the inboard chamfering of left guide plate inclined-plane 12 touches the left surface 16 of fanning strip 9, because this moment, fanning strip right flank 17 was faced 15 applyings directly with right guide plate 5 inboards, left side guide plate 2 can't move upward, driving mechanism 10 drives right guide plate 5 and moves downward as Fig. 1 (b), fanning strip 4 is because degree of freedom restriction still keeps fanning strip right flank 17 and right guide plate inboard to face 15 applyings directly, stop left guide plate 2 motions, driving mechanism 10 drives the descending rotation of right guide plate 5, make driving shaft 11 enter the importing curve 6 of left guide plate 2, right guide plate 5 continues to move downward fanning strip right flank 17 and right guide plate 5 inboards and faces 15 directly can not fit as Fig. 1 (c) time, fanning strip no longer can stop left guide plate 2 to move upward, thereby at this moment the driving shaft 11 importing curve 6 that entered left guide plate 2 fully drives the execution reset of breaker that left guide plate 2 motions make dropout.
As mentioned above, the utility model can realize that left guide plate and right guide plate carry out circuit breaker and thread off when the separating brake position, the axle of driving mechanism all can enter the importing curve of left guide plate 2 and right guide plate 5 lower ends, drives the execution reset of breaker of threading off thereby drive left and right sides guide plate.
Left side guide plate 2 faces 13,15 with right guide plate 5 directly as long as importing curve 6,7 exceeds guide plate inboard, the left and right sides respectively, and then it is provided with the position, and quantity is set, and size is not done special qualification.As long as be positioned at the appropriate location of left guide plate 2 and right guide plate 5, then in not breaking away from this patent purport scope, can suitably change.
Claims (1)
1. the mechanical interlock mechanism of an automatic transfer switching electric appliance is characterized in that: be used to operate the left guide plate of carrying out circuit breaker and right guide plate and be respectively arranged with and exceed the importing curve of facing directly its inboard.
