Embodiment
Referring to Fig. 1 ~ 6, Fig. 1 is the general structure schematic diagram of the utility model vacuum switch with spring operating mechanism; Fig. 2 is the right side view of Fig. 1; Fig. 3 is the partial enlarged drawing of Fig. 2 bottom; Fig. 4 is the partial enlarged drawing of Fig. 3 bottom; Fig. 5 is the lower left corner part end view of Fig. 3; Fig. 6 is the right side perspective view of Fig. 5.By Fig. 1 ~ 6 as can be seen, the utility model vacuum switch spring operating mechanism, mainly by header board 15, back plate 7, energy storage axle 12, separating brake dropout semiaxis 6, secondary transmission intermediate shaft assembly 8, energy storage axis cam 13, energy storage axle crank 5, main extension spring 2, fixedly link plate I 1, fixedly link plate II 3, output toggle arm 9, output toggle arm roller 11, truckle 20, operating mechanism link 21 and output toggle arm axle 22 are formed.Described header board 15 and plate 7 front and back, back be arranged in parallel, form a semi-enclosed structure by many mechanism supports bar II 14 and 16 support and connection of mechanism supports bar I between header board 15 and the back plate 7, described energy storage axle 12, separating brake dropout semiaxis 6, output toggle arm axle 22 and secondary transmission intermediate shaft assembly 8 are connected between described header board 15 and the back plate 7 by the bearing at two ends separately is parallel, stretch out outside the plate 7 of described back described energy storage axle 12 rear ends, energy storage axis cam 13 is installed in the centre of energy storage axle 12, energy storage axle crank 5 is installed in the rear end of energy storage axle 12, one end of described main extension spring 2 links to each other with fixing link plate I 1, the other end links to each other with fixing link plate II 3, and fixedly link plate II 3 links to each other with described energy storage axle crank 5 by bearing.Described output toggle arm axle 22 front ends stretch out outside the described header board 15, and output toggle arm 9 is installed in the middle of the output toggle arm axle 22, and output toggle arm roller 11, truckle 20 and operating mechanism link 21 all are rotatably connected on the edge of output toggle arm 9 with bearing pin.
Described secondary transmission intermediate shaft assembly 8 mainly is made up of intermediate propeller shaft 10, buckle 17 and the power of unloading sincere sub 18.Described buckle 17 adopts integral structure, buckle 17 is fixedly connected on the intermediate propeller shaft 10 by the pin I, the power of unloading sincere sub 18 is fixedly connected on the buckle 17 by pin II 19, the cooperation that contacts with described separating brake dropout semiaxis 6 of the arc surface of buckle 17, sincere sub 18 the arc surface of the power of the unloading cooperation that contacts with the outer rim of described truckle 20.
Its combined floodgate operation principle: when driving 12 rotations of energy storage axle by energy storage combined floodgate motor or the rotation of manual operation power, by 5 rotations of energy storage axle crank main extension spring 2 is stretched, when energy storage axle crank 5 Rotate 180s °, thereby main extension spring 2 is stretched to the purpose that the extreme position of conllinear reaches energy storage.When 5 rotations of energy storage axle crank surpass 180 ° of conllinear dead-centre positions, thereby rapid release of the energy of main extension spring 2 makes energy storage axis cam 13 bump output toggle arm rollers 11 output toggle arm 9 be rotated and the driving switch combined floodgate.When the energy of being laid in when main extension spring 2 discharges, 5 rotations of energy storage axle crank, drive 12 rotations of energy storage axle, thereby drive energy storage axis cam 13 high speed rotating, make energy storage axis cam 13 high-speed impact output toggle arm rollers 11, drive output toggle arm 9 rotations, realize the combined floodgate of switch, and keep "on" position by the power of unloading sincere sub 18.This moment, switching force decomposed on the power of unloading of secondary transmission intermediate shaft assembly 8 sincere sub 18, was pressing the power of unloading sincere sub 18 by the truckle on the output toggle arm 9 20, and the power of unloading sincere sub 18 is rotated around intermediate propeller shaft 10.Buckle 17 blocks it by separating brake dropout semiaxis 6, makes it keep reliable closing position.
The separating brake operation principle:
Because secondary transmission intermediate shaft assembly 8 puts on power on the power of unloading sincere sub 18 with output toggle arm 9 and utilizes lever principle to resolve into very little power to pass to buckle 17, pass to separating brake dropout semiaxis 6 again by buckle 17, realize finally that by the secondary transmission tripping force of separating brake dropout semiaxis 6 reduces greatly.Make the current mode overcurrent coil or the very little power of shunt opening trip coil output of switch just can make the switch separating brake like this.When shunt opening trip coil or 6 rotations of overcurrent coil motion drive separating brake dropout semiaxis, and order about buckle 17 and axially rotate around intermediate propeller shaft 10, make secondary transmission intermediate shaft assembly 8 integral body turn over an angle, the power of unloading sincere sub 18 is thrown off the output toggle arm 9 that withstands, and output toggle arm 9 is realized rapid separating brake by the reaction force of switch combined floodgate contact.
