Be fixed with isolation grooved cam 1 and breaker cam 10 on the main shaft 9, the isolation grooved cam 1 drive every
Off-axis 8, the isolation output of axis 8 drives the separating brake of disconnecting switch, and the breaker cam 10 drives killer switch
Separating brake, when separating brake, killer switch elder generation separating brake, separating brake after disconnecting switch；Separating brake is complete, and block protrusion 29 is blocked by closing pawl 30
Main shaft 9 can not rotate, that is, reset.
A kind of miniaturization series connection linkage vacuum circuit breaker, earthing switch include: with killer switch cascade process
Earthing switch making process: grounding shaft 22, which rotates counterclockwise, drives earthing switch first to close a floodgate, while driving shift fork part
60, the shift fork part 60 disconnects the driving of isolation axis 8, rotate isolation axis 8 can not；
II 56 the chain shaft 12 of energy storage is driven by driver plate 23 in flakes on the grounding shaft 22, the energy storage is chain
Shaft 12, which rotates counterclockwise, to be completed disconnecting switch and connects with killer switch making process, is closed a floodgate after killer switch, it is described every
Off-axis 8 driving is disconnected by shift fork part 60, and isolation axis 8 can not rotate, and disconnecting switch attonity is in gate-dividing state；
Grounding switch tripping process: after earthing switch closes a floodgate, grounding shaft 22, which rotates clockwise, drives earthing switch elder generation separating brake,
II 56 the chain shaft 12 of energy storage is driven by driver plate 23 in flakes on the grounding shaft 22, the chain shaft 12 of the energy storage is suitable
Hour hands rotation completes disconnecting switch and connects with killer switch separating brake process, separating brake after killer switch, and disconnecting switch has been
Gate-dividing state will not act.
The utility model has the advantages that
1. the present invention is since isolator is connected linkage with breaker, when combined floodgate, disconnecting switch is first closed a floodgate, and breaker is opened
It closes a floodgate behind pass；When separating brake, killer switch elder generation separating brake, separating brake after disconnecting switch；When contact of earth, earthing switch first closes a floodgate, and breaks
It closes a floodgate after road device switch, disconnecting switch attonity is in gate-dividing state；When being grounded separating brake, earthing switch elder generation separating brake, breaker is opened
Separating brake, disconnecting switch attonity are in gate-dividing state behind pass；On/off switch movement is successively clearly demarcated, by once, closes rapidly.It can be wide
General use is on the vacuum circuit breaker of 12KV, 24KV, 40.5KV.
2. the present invention is when carrying out ground connection operation, after earthing switch closure, breaker is with isolator due to connection of connecting
Dynamic to be closed at, three components are all closed meeting so that entire short circuit；Circuit interrupter grounding through the invention assists knot
For structure when carrying out contact of earth movement, grounding shaft rotation can easily disconnect the connection of isolation axis, so that isolation axis can not rotate；
It when being grounded barrier gate operation, and can that axis normal work is isolated.
3. the present invention is after vacuum bubbles (also known as breaker vacuum arc-chutes) are cut-off, isolator is then turned off, and restores electricity
Pressure can not generate arcing between the big fracture of isolator, and two fractures of isolator make vacuum bubbles (also known as vacuum interrupter)
Can not re-ignition, also avoid restore voltage influence.
