Lever 56, side plate is additionally provided with vertical waist hole, and one end of pin is through vertical waist hole and hand lever
One end of 56 is hinged, and the other end of hand lever 56 reaches the outside of cabinet 5, after having overhauled
First by earthing group 3 separating brake, now the lobe of cam 54 is away from bearing pin 55, dials up manually
Bar 56, hand lever 56 drives bearing pin 55 to move downward until bearing pin 55 departs from separating brake station groove, this
Time can free actuating operation axle I 51, isolation knife group 2 unlocks.
Earthing group 3 and the interlock of vacuum interrupter group 4 in the present embodiment are as follows, operate axle
It is also equipped with plate 57 on II 52, in cabinet 5, is slidably fitted with montant, the fixing peace in one end of montant
Equipped with the pressing plate 58 coordinated with plate 57, the other end of montant reaches the outside of cabinet 5, machine
The outside of case 5 is provided with pin 61, and montant is connected by contiguous block is fixing with the upper end of pin 61, gear
In the lower end of bar 61 extend into switch cubicle 6 and be positioned at the side of breaker open operation plate 62, work as earthing
During group 3 combined floodgate, plate 57 meeting band dynamic pressure plate 58 is descending, and pressing plate 58 drives pin 61 descending, gear
The lower end of bar 61 is blocked separating brake plate 62 and is made chopper cannot be carried out sub-switching operation, thus is grounded
Cutter group 3 and the interlocking of vacuum interrupter group 4, and meanwhile isolation knife group 2 and earthing group 3 be also
It is in Interlock Status, thus realizes isolation knife group 2, earthing group 3 and the machine of vacuum interrupter group 4
Tool is interlocked.
Isolation knife group 2 in the present embodiment drives isolation knife group 2, transmission component bag by transmission component
Include and be arranged on the driven gear that the driving gear 21 of operation axle I 51 end engages with driving gear 21
22 and the cutter shaft 23 that is socketed in driven gear 22 wheel bore, cutter shaft 23 drives isolation knife group to deflect,
Be further fixed on framework 1 isolate tool rest, isolation knife group 2 operation axle I 51 driving under with isolation knife
Seat occlusion.
Earthing group operating mechanism in the present embodiment drives earthing group 3, connecting rod by linkage
Mechanism includes the first linked block 31, connecting rod 32 and the second linked block 33 being hinged successively, first
Linked block 31 is fixing with operation axle II 52 end to be connected, and the second linked block 33 is fixedly connected with rotating shaft
34, rotating shaft 34 is installed earthing group 3, the side of the movable end of earthing group 3 bottom is provided with and connects
Ground contact, earthing group 3 connects with grounding contact under the driving of operation axle II 52.
Vacuum circuit breaker in the present embodiment also includes that earthing combines separating brake holding means, earthing group
On/off switch holding means includes being arranged on the cunning that the connecting lever 35 of rotating shaft 34 end is connected with connecting lever 35
Dynamic set 36 and the guide post 37 being socketed in slip cap 36, guide post 37 is arranged on the axle of fixed plate
In hole, guide post 37 being arranged with stage clip 38, one end of stage clip 38 is fixing with slip cap 36 to be connected,
The other end of stage clip 38 is fixed in fixed plate.When earthing group 3 by separating brake Switch of working position to closing
During lock station, being rotated by operation axle II 52 drive shaft 34, rotating shaft 34 can drive connecting lever 35 turns
Dynamic, connecting lever 35, while rotating, can drive slip cap 36 to slide, and slip cap 36 extrudes stage clip
38, after arriving combined floodgate station, stage clip 38 stretches and rotating shaft 34 is acted against relevant position, as
Really separating brake rotating shaft 34 must pull against the pressure of stage clip 38 and could rotate, and therefore earthing group 3 is at stage clip
It is maintained at closing position under the effect of 38, prevents earthing from upspringing or unusual fluctuation, it is ensured that the safety of electrical equipment
Property.
In order to reduce the stress of framework 1, the side fixed installation vacuum interrupter group 4 of framework 1, frame
The side of frame 1 is provided with mounting seat, and mounting seat is fixed with two insulators 42, two insulators 42
End be provided with fixed mount 41, the two ends up and down of vacuum interrupter are fixed by two fixed mounts 41 respectively,
Two insulators 42 and vacuum interrupter constitute triangle fixed structure, and such vacuum interrupter group 4 is borrowed
Helping insulator 42 to be fixed on the side of framework 1, framework 1 need not bear vacuum interrupter straight down
Gravity, triangle fixed structure has disperseed the gravity of vacuum interrupter to reduce framework 1 to be subject to further
Power, framework 1 is unlikely to deform.
Framework 1 is rotatably mounted with drive shaft 43 near the side of vacuum interrupter group 4, drives
