In side plate 111 outsides, and be set in camshaft 21 and be provided with Handleset 22, specifically see Figure 18,19, described Handleset 22 comprises handle 221, connecting rod 222, the first shell 223, second housing 224, the first ratchet 225, the second ratchet 226; Gear 227, extension spring 228.The first described shell 223 is positioned at gear 227 both sides with second housing 224, described gear 227 is provided with the hole coordinating with camshaft 21 profiles, thereby when described gear 227 is enclosed within on camshaft 21, synchronize rotation with camshaft 21, described the first shell 223, second housing 224 are provided with circular hole, when the first shell 223 is enclosed within on camshaft 21 with second housing 224, camshaft 21 rotates relatively, and the first described shell 223 interfixes with second housing 224.On the first described shell 223 and second housing 224, hub setting has the first ratchet 225, the first ratchets 225 to be connected with an extension spring 228, and the other end of extension spring 228 connects the first shell 223, and 228 pairs of the first ratchets 225 of this extension spring apply the power of gear 227.The second described ratchet 226 hub settings, on side plate 111, and are applied the power of gear 227 to the second ratchet 226 by a reply spring.Under the first above-mentioned ratchet 225 and the second ratchet 226 mating reactions, can only there is one-directional rotation in described gear 227 under the drive of handle 221, and the rotation of this direction drives camshaft 21 one-directional rotation, and compression energy assembly 12.
When the movable contact system of circuit breaker is during in closure state, referring to Figure 10 and Figure 12, due to one end of pendulum extension bar 1921 one end and first connecting rod 133, hinged by same axle and movable contact system.Therefore, the first described forked bar 192 is followed moving contact motion, protruding axle 1922 on it is also being followed the first forked bar 192 to the lateral movement away from disk 201, in motion process, drive the equidirectional swing of external part 1561, thereby drive combined floodgate revolving part 156 counterclockwise to rotate, the second cantilever arm 1563 on combined floodgate revolving part 156 promotes combined floodgate slide bar 155 bottoms, the pushing wall 1551 of slide bar 155 of closing a floodgate upwarps and departs from and coordinates with described projection 1531, and now the reclosing command in the external world cannot be realized.Meanwhile, the compressing that combined floodgate slide bar 155 is removed the ready indication piece 171 that closes a floodgate, closes a floodgate ready indication piece 171 under the effect of torsion spring 172, and its indication interface display is prepared not-ready state.
On the other hand, when the operating mechanism of circuit breaker is not when energy storage completes, referring to Figure 10 and Figure 12, the first cantilever arm 1562 of combined floodgate revolving part 156 is 2012 places of the depression in disk 201 not, and on outer in disk 201.Now, combined floodgate revolving part 156 also counterclockwise rotates, the second cantilever arm 1563 on combined floodgate revolving part 156 promotes combined floodgate slide bar 155 bottoms, and the pushing wall 1551 of the slide bar 155 that closes a floodgate upwarps and coordinates with described projection 1531 disengagings, and now the reclosing command in the external world cannot be realized.Meanwhile, the compressing that combined floodgate slide bar 155 is removed the ready indication piece 171 that closes a floodgate, the described ready indication piece 171 of combined floodgate is under the effect of torsion spring 172, and its indication interface display is prepared not-ready state.
Based on above-mentioned two situations, counter push away known, when moving contact of breaker system is in gate-dividing state, in the situation that breaker mechanism energy storage completes simultaneously, the revolving part 156 that closes a floodgate can not rotate counterclockwise, the slide bar 155 that closes a floodgate be subject to the first spring 158 effect and in the coordinating in scope of projection 1531, now close a floodgate and can operate.Meanwhile, the ready indication piece 171 of combined floodgate slide bar 155 pushing combined floodgate, the ready indication piece 171 that closes a floodgate shows the ready state that closes a floodgate.
Above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
