The high dynamic stability device for switching that this utility model provides is alternatively arranged as transfer switching equipment and uses, it is correspondingly arranged two static contact parts, meanwhile, two contacts of moving contact body 5 are mounted on dynamic silver point 4, and moving contact shell is installed dynamic silver point side at two contacts and is equipped with tooth I201；Moving contact body rotates, and realizes the conjunction of two dynamic and static silver points respectively, opens, and then controls different electrical power and powers；As shown in Figure 9.
This high dynamic stability device for switching off-state, i.e. opens a sluice gate state, and as shown in Fig. 1,1a, extension spring I12 pulls hook plate 20, and dynamic iron core 9 is inserted in solenoid 7, and extension spring II17 applies pulling force to rotation rail 16, and rotation rail 16 is motionless.
The center square hole of the moving contact shell 2 of this high dynamic stability device for switching is enclosed within the square main shaft of mechanism, turns square main shaft, then drives moving contact shell 2 to rotate, and the effect lower moving contact body 5 at spring 3 rotates；This high dynamic stability device for switching is changed to closing position by opening a sluice gate position, and when the hook of the projection on moving contact body 5 with hook plate 20 top contacts, as shown in Fig. 2,2a, dynamic silver point 4 not yet contacts with quiet silver point 25, and circuit does not turns on；Moving contact part continues to rotate, the protrusions press hook plate 20 on moving contact body 5, and the bearing pin 10 of dynamic iron core 9 slides in the strip hole of hook plate 20, and hook plate 20 rotates counterclockwise, and drives dynamic iron core 9 to slide in and out, pulls extension spring I12 simultaneously；Tooth I201 on moving contact shell 2 engages with the tooth II210 in wobble plate 21, drives wobble plate 21 to turn clockwise；The strip hole I of rotation rail 16 rotates up, and extension spring II17 is elongated, and plate 14 slides to the direction of hook plate 20；Time inside the hook protruding out into hook plate 20 on moving contact body 5, dynamic silver point 4 and quiet silver point 25 come into contact with, as shown in Fig. 3,3a；Moving contact part continues to rotate, the motion of above-mentioned each parts continues, projection on moving contact body 5 is stuck in inside the hook of hook plate 20, and dynamic silver point 4 and quiet silver point 25 close, as shown in Fig. 4,4a, now, plate 14 slides into the top of axle I13, withstands axle I13, makes hook plate 20 not move upward, as it is shown in figure 5, moving contact part produces the excess of stroke.
At closing position, this high dynamic stability device for switching compensation contact pressure, thus the process improving the tolerance in short-term of switch is as follows:
When carrying out KA Rms test, the logical bigger electric current of major loop, electric current produces electrodynamic repulsion force between dynamic silver point 4 and quiet silver point 25, be scolded out by dynamic and static contact, now, the opposite force balanced with this repulsion includes the elastic force that 1. spring 3 provides to moving contact body 5；2. the hook plate 20 pulling force to moving contact main body 5.On the one hand hook plate 20 comes from extension spring I12 to the pulling force of moving contact main body 5, on the other hand comes from the pulling force that hook plate 20 is applied by dynamic iron core 9 by bearing pin 10.Owing to the electric current that major loop is bigger has flow through solenoid 7, static iron core 11 can produce bigger electromagnetic attraction to dynamic iron core 9, so that dynamic iron core 9 produces pulling force to hook plate 20.Hook plate 20 is the repulsion of a part of dynamic and static contact to the tension balanced of moving contact 5, making can be by bigger KA Rms in the case of not increasing contact pressure, improve tolerance in short-term, also make contact can improve the connection breaking capacity of switch with the bigger electric current of disjunction owing to reducing contact pressure.
When switch is moved to open position by closing position, moving contact shell 2 turns clockwise, and has run the excess of stroke, as shown in Fig. 6,6a；nullMoving contact main body 5 starts to rotate，Tooth I201 on moving contact shell 2 engages the tooth II210 in wobble plate 21，Wobble plate 21 is driven counterclockwise to rotate around axle V23，Wobble plate 21 drives rotation rail 16 to be rotated clockwise，Rotation rail 16 drives plate 14 to slide to the left，At Fig. 7、During 7a position plate 14 departing from the contacting of axle I13，Moving contact shell 2 continues to turn clockwise，Moving contact main body 5 can be driven to rotate，Moving contact main body 5 pulls up hook plate 20，Hook plate 20 meeting band movable slider 27 overcomes the pressure upward sliding of stage clip 28，When moving to Fig. 8 position，Moving contact 5 abjection contacts with hook plate 20，Return to open position，Such as Fig. 1、Shown in 1a，Miscellaneous part is the most all at extension spring I12、Under the effect of extension spring II17 and stage clip 28，Return to initial position.
