Stored energy mechanism of the present invention has increased protective device, and this kind stored energy mechanism can effectively solve circuit breaker causes the scaling loss circuit breaker because of manual energy storage when closing a floodgate problem.
Description of drawings
Above-mentioned feature and advantage with other of the present invention will be below becomes more obvious after in conjunction with the accompanying drawings and embodiments the description, and identical in the accompanying drawings mark is represented identical feature, wherein:
Schematic diagram when Fig. 1 is to use the breaker closing of stored energy mechanism of the present invention;
Schematic diagram when Fig. 2 is to use the breaker open operation of stored energy mechanism of the present invention.
Embodiment
Further describe technical scheme of the present invention below in conjunction with drawings and Examples.
With reference to figure 1 and Fig. 2, the invention provides a kind of stored energy mechanism of air circuit, with close/brake separating mechanism 100 is used, close/brake separating mechanism 100 links to each other with the main shaft 102 of circuit breaker, controls the opening and closing of contact of breaker by the rotation of main shaft 102; The handle 204 of stored energy mechanism and ratchet 206 are enclosed within on the energy storage axle 202, sincere sub 208 be positioned at handle 204 with sincere sub 208 back-moving springs that link to each other 210 and be interlocked with ratchet 206, motor-operating mechanism also is positioned on the energy storage axle 202.A main improvement of the present invention is that it also comprises protection mechanism 300, and protection mechanism has two states: when circuit breaker was "on" position, ratchet 206 and sincere sub 208 was separated from each other, when circuit breaker is gate-dividing state, and ratchet 206 and sincere sub 208 mutual interlocks.The form of the protection mechanism 300 that can adopt has multiple, and Fig. 1 and Fig. 2 show a kind of form wherein, in the protection mechanism 300 of this kind form, it comprises: guide 302, the centre has a hole, is enclosed within on the energy storage axle 202, and the periphery of guide 302 is the projection circular arc 304 that radius does not wait; Connecting rod 306, in order to the state of the main shaft 102 of surveying circuit breaker, an end of connecting rod 306 links to each other with cantilever 104 on the circuit breaker main shaft 102, and the other end of connecting rod 306 is connected to guide 302 and extends an end; This end that connecting rod 306 links to each other with guide 302 has a long lumbar hole 308; Spacer pin 310 is positioned at and is used to limit sincere sub 208 rotation on sincere sub 208.
The operation principle of stored energy mechanism with protection mechanism that goes out illustrated in figures 1 and 2 is as follows: when circuit breaker is in "on" position; with reference to shown in Figure 1; cantilever 104 on the circuit breaker main shaft 102 relatively and the rotated position of circuit breaker when being in separating brake certain angle; main shaft 102 state at this moment is transferred to guide 302 by connecting rod 306; make guide 302 also produce corresponding the rotation; because the periphery of guide 302 is circular arcs that radius does not wait; after the rotation, guide 302 forwards on the large radius arc with sincere sub 208 contacted small-radius arcs from original.At this moment, according to the embodiment among Fig. 1, the projection circular arc 304 than long radius on the guide 302 backs down sincere sub 208 spacer pin 310 in the handle 204, thereby will be originally sincere sub 208 separate (small-radius arc on the guide 302 can make ratchet 206 be interlocked with sincere sub 208) with ratchet 204 with ratchet 206 fastens, even misoperation at this moment occurs, spur handle 204 and carried out manual energy storage, because sincere sub 208 on the handle 204 is in the state that separates with ratchet 206, ratchet 206 just can not drive energy storage axle 202 and rotate, and this moment, circuit breaker still was in the state that safety is closed a floodgate.In the process of motion, the effective interaction length of connecting rod 306 can change, so be provided with a long lumbar hole 308 at an end of connecting rod 306, makes protective device to put in place smoothly.
And when circuit breaker is in gate-dividing state, as shown in Figure 2, the projection circular arc 304 of guide 302 forwards small-radius arc and sincere sub 204 contacted positions to, and can not back down sincere sub 204 this moment, sincere sub 204 with ratchet 206 interlock mutually, just manually energy storage when at this moment spurring handle 204.
For protection mechanism, also can adopt the form (not illustrating in the drawings) of separating member, separating member can be an inserted sheet, can be inserted into sincere sub 208 and ratchet 206 between both are separated, when not using separating member sincere sub 208 with ratchet 206 interlock mutually.The protection mechanism of employing separating member form can play the effect of protection equally.
Stored energy mechanism of the present invention has increased protective device, and this kind stored energy mechanism can effectively solve circuit breaker causes the scaling loss circuit breaker because of manual energy storage when closing a floodgate problem.
The foregoing description provides to being familiar with the person in the art and realizes or use of the present invention; those skilled in the art can be under the situation that does not break away from invention thought of the present invention; the foregoing description is made various modifications or variation; thereby protection scope of the present invention do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
