Camshaft 21 pass through described cam gear 20, and with cam gear 20 synchronous axial system.Camshaft 21 is articulated in described
On side plate 111.
Outside side plate 111, and be set in camshaft 21 and be provided with Handleset 22, be specifically shown in Figure 18,19, described hand
Handle assembly 22 includes 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.Described first shell 223 and second housing 224 are located at gear 227 both sides, described gear
227 are provided with the hole with camshaft 21 form fit, thus when described gear 227 is enclosed within camshaft 21, with camshaft
21 synchronous axial system, the first described shell 223, second housing 224 are provided with circular hole, 224 sets of the first shell 223 and second housing
When on camshaft 21, can opposing cam axle 21 rotate, the first described shell 223 is interfixed with second housing 224.
The first described shell 223 has the first ratchet 225 with hub setting on second housing 224, and the first ratchet 225 is connected with an extension spring 228,
The other end of extension spring 228 connects the first shell 223, and this extension spring 228 applies to press close to the power of gear 227 to the first ratchet 225.Described
The second ratchet 226 hub setting on side plate 111, and by one reply spring to the second ratchet 226 apply press close to gear 227 power.On
Under the first ratchet 225 and the second ratchet 226 mating reaction stated, described gear 227 can only occur under the drive of handle 221
One-directional rotation, rotational band moving cam axle 21 one-directional rotation of the direction, and compression energy assembly 12.
When the movable contact system of breaker is in closure state, referring to Figure 10 and Figure 12, due to putting extension bar 1921 one end
With one end of first connecting rod 133, hinged by same axle and movable contact system.Therefore, described first forked bar 192 is with servo-actuated
Contact moves, and protruding shaft 1922 thereon also followed by the first forked bar 192 to the lateral movement away from disk 201, motion process
The middle drive equidirectional swing of external part 1561, thus drive combined floodgate revolving part 156 rotate in an anti-clockwise direction, combined floodgate revolving part 156
On the second cantilever arm 1563 promote combined floodgate slide bar 155 bottom, then combined floodgate slide bar 155 push wall 1551 upwarp and with described
Raised 1531 depart from cooperation, and that is, now extraneous reclosing command cannot be realized.Meanwhile, combined floodgate slide bar 155 releases and prepares to closing a floodgate
The compressing of ready indication piece 171, then close a floodgate ready indication piece 171 in the presence of torsion spring 172, and its instruction interface display is accurate
Standby not-ready state.
On the other hand, when the operating mechanism of breaker is in non-energy storage and completes, referring to Figure 10 and Figure 12, combined floodgate revolving part
156 the first cantilever arm 1562 is not at the depression 2012 of disk 201, and is on the outer of disk 201.Now, close a floodgate
Revolving part 156 also rotate in an anti-clockwise direction, the second cantilever arm 1563 on combined floodgate revolving part 156 promotes combined floodgate slide bar 155 bottom,
Then the wall 1551 that pushes of combined floodgate slide bar 155 upwarps and departs from cooperation with described projection 1531, i.e. now extraneous reclosing command
Cannot realize.Meanwhile, combined floodgate slide bar 155 releases the compressing to the ready indication piece 171 that closes a floodgate, then described combined floodgate just prepares
In the presence of torsion spring 172, its instruction interface display prepares not-ready state to thread indication piece 171.
Based on above-mentioned two situations, counter pushing away understands, when moving contact of breaker system is in gate-dividing state, breaker simultaneously
In the case that mechanism's energy storage completes, then combined floodgate revolving part 156 will not rotate counterclockwise, then combined floodgate slide bar 155 is subject to the first spring 158
Effect and be in raised 1531 cooperation in the range of, now close a floodgate operable.Meanwhile, combined floodgate slide bar 155 pushes to close a floodgate and prepares
Ready indication piece 171, the ready indication piece 171 display ready state of combined floodgate of closing a floodgate.
Above-described embodiment only technology design to illustrate the invention and feature, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implements according to this, can not be limited the scope of the invention with this.All according to the present invention
Equivalence changes or modification that Spirit Essence is made, all should be included within the scope of the present invention.
