Abstract
The utility model discloses a circuit breaker closing self-locking protection mechanism. An integer is corresponding to a circuit breaker actuator mechanism switching closing turn arm and operates a starting point on a moving direction side. The utility model comprises a cantilever shaft which is fixed on a side plate of the circuit breaker actuator mechanism, a swing stem, a rest pad, a rest pin and a top arm. The cantilever shaft is dynamically provided with the swing stem and the rest pad is fixed on the cantilever shaft. The rest pin is arranged on the rest pad. The rest pin is dynamically provided with the top arm. The switching closing of the circuit breaker actuator mechanism switching closing is used as thrust to push the swing stem rotating. The placed position of a top block is changed and the top block acts up and down, which realizes the action control to the circuit breaker actuator mechanism closing turn arm and realizes the closing self-locking protection in the circuit breaker actuator mechanism closing state and when the closing action can not be processed. The utility model is simple and practical and actualizes control and protection from the operation source. In addition, the utility model is never damaged, which greatly enhance using performance and service life.

Background technology
Current production and operating circuit breaker all possess combined floodgate self-lock protection function; and the prior art that realizes this function all is the feed motion information that obtains on the circuit breaker main shaft; through the combination of action message driving-chain transmission with latching device, the control circuit breaker can not close a floodgate under "on" position again.Its complex structure, and in breaker closing moment, its main shaft responsiveness is exceedingly fast, and causes the message transmission chain fragile, influences reliability and useful life.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of present technology, and provides a kind of simple and practical, implements the control protection from the operation source, and the breaker closing self-lock protection mechanism that never damages, to improve the serviceability and the life-span of circuit breaker.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: breaker closing self-lock protection mechanism, the technical measures of taking comprise: include the cantilevered axle that is fixed on the breaker operation mechanism side plate, also include fork, rest pad, fulcrum post and top arm; Cantilevered axle is moving is furnished with fork, and also is fixed with rest pad, and fulcrum post is housed on the rest pad, moving top arm of joining on the fulcrum post.
The technical measures of taking also comprise: breaker operation mechanism also includes separating brake connecting lever and combined floodgate connecting lever; The position of fork and top arm corresponds respectively to the starting point of the operational movement direction side of separating brake connecting lever and combined floodgate connecting lever; And keep 1.5-2 millimeter spacing.
Above-mentioned mounting structure preferably is that the cantilevered axle head end is fixed on the side plate through securing member; Fork is moving to be fitted in the middle of the cantilevered axle; Rest pad is fixed on the cantilevered axle breech face.
The utility model integral body is corresponding to breaker operation mechanism divide-shut brake connecting lever, the starting point of operational movement direction side; Include the cantilevered axle that is fixed on the breaker operation mechanism side plate, also include fork, rest pad, fulcrum post and top arm; Cantilevered axle is moving is furnished with fork, and also is fixed with rest pad, and fulcrum post is housed on the rest pad, moving top arm of joining on the fulcrum post.It is simple and practical, implements the control protection from the operation source, and never damages the serviceability and the life-span of improving circuit breaker greatly.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 is to Figure 4 shows that breaker closing self-lock protection mechanism, and its integral body is corresponding to the starting point of the operational movement direction side of the divide-shut brake connecting lever of breaker operation mechanism; It includes the cantilevered axle 2 that is fixed on the breaker operation mechanism side plate 1, also includes fork 3, rest pad 4, fulcrum post 5 and top arm 6; Cantilevered axle 2 is moved is furnished with fork 3, and also is fixed with rest pad 4, and fulcrum post 5 is housed on the rest pad 4, moving top arm 6 of joining on the fulcrum post 5.The equipped jointly breaker closing self-lock protection mechanism that forms of above-mentioned each parts.Structure is that cantilevered axle 2 head ends are fixed on the side plate 1 through securing member preferably; Fork 3 moving fitting in the middle of the cantilevered axle 2; Rest pad 4 is fixed on cantilevered axle 2 breech faces.
Breaker operation mechanism also includes separating brake connecting lever 7 and combined floodgate connecting lever 8; The above-mentioned fork 3 and the position of top arm 6 correspond respectively to the starting point of the operational movement direction side of described separating brake connecting lever 7 and combined floodgate connecting lever 8; And keep 1.5-2 millimeter spacing.
When circuit breaker is implemented breaking-closing operating; by operation thrust to breaker open operation connecting lever 7 and combined floodgate connecting lever 8; promote fork 3 rotations; the gear of putting that has changed 3 pairs of top arms 6 of fork is put; make top arm 6 knee-actions; realization reaches the combined floodgate self-shield that can not carry out closing operation under the breaker closing state to the action control of breaker closing connecting lever 8.
Embodiment
As shown in Figure 2, after circuit breaker carried out sub-switching operation, fork 3 retainings were put top arm 6 front ends, make top arm 6 perks, and the combined floodgate connecting lever 8 of breaker operation mechanism is not blocked and can carries out closing operation.
As Fig. 3; shown in 4; during breaker switching-on operation; operation thrust to breaker operation mechanism combined floodgate connecting lever 8; promoting fork 3 its gears of putting to top arm 6 of rotation change puts; 6 times iron of top arm; combined floodgate connecting lever 8 continues to advance; synchronous to breaker closing; top arm falls to default recessed plane for 6 times and is held on the fork 3; instant closing operation thrust is eliminated; combined floodgate connecting lever 8 its greater than with the effect of the reset force of top arm 6 bevel friction power under retreat to original position, top arm 6 promptly at present iron block combined floodgate connecting lever 8, reach the combined floodgate self-lock protection that under the breaker closing state, can not carry out closing operation.
Most preferred embodiment of the present utility model is illustrated, and various variations or the remodeling made by those of ordinary skills can not break away from scope of the present utility model.
