With reference to Fig. 1 ~ 11, to on-load switch isolation knife of the present invention, the action process of earthing two-stage forward operation mechanism
Illustrate：
When switch divides position with being located at isolation splice grafting, alignment switching mechanism panel 2 isolates splice grafting ground point position（Small gap refers to
Show position）, the promotion of insertion operation key 1 is operated protects lock tube 14 to be retracted, and the small dome platform on operation key 1 puts in switch completely
Mechanism panel 2, big dome platform is blocked in the outside of switching mechanism panel 2, the groove on now two-stage propulsion clutch 4 be grounded from
The cutting dislocation of the linkage protrusion of crank 6 is closed, two-stage advances clutch 4 to be separated with ground connection clutch-linkage crank 6, it is impossible to operational grounding
Switch, prevents disconnecting switch mistiming in the close position from closing earthed switch, and isolation coupled axle-pin 5 is located at the L that two-stage advances clutch 4
In the short groove in axial direction of shape groove, two-stage propulsion clutch 4 is connected with isolation switch shaft 7, now can be with disconnecting switch operation；
Turn clockwise operation key 1, drives two-stage propulsion clutch 4 to be turned clockwise with fairlead 3, and drive is kept apart
Close axle 7 to turn clockwise, drive isolation knife separating brake, while drive the isolation ground connection division direction board 13 on fairlead 3 to rotate, when
When isolation axle limiting plate 9 encounters isolation axle gag lever post 8, isolation separating brake is in place；
Now isolation ground connection division direction board 13 indicates isolation separating brake ground connection open position, and the size on operation key 1 is convex
Round platform has rotated to isolating tap point position（Big gap position above）, two-stage propulsion clutch 4 on groove targeted by
The cutting that ground connection clutch-linkage crank 6 is protruded above；If client needs operational grounding to switch, i.e., insert operation handle to the inside again
Operation key 1, operation protection lock tube 14 is promoted further to be retracted, the size dome platform on operation key 1 puts in switching on and shutting down completely
Structure panel 2, the cutting for promoting the groove on two-stage propulsion clutch 4 to be protruded above with ground connection clutch-linkage crank 6 is fastened, and two-stage is pushed away
Enter clutch 4 to be connected with ground connection clutch-linkage crank 6, can now be switched with operational grounding, isolation coupled axle-pin 5 is advanced positioned at two-stage
In radial direction elongated slot in the L-shaped groove of clutch 4, two-stage propulsion clutch 4 is separated with isolation switch shaft 7, when two-stage advances clutch
Isolation switch shaft 7 dallies when device 4 rotates, it is impossible to disconnecting switch operation；
Turn clockwise operation key 1, drives two-stage propulsion clutch 4 to turn clockwise, and drives ground connection clutch-linkage bent
Handle 6 is turned clockwise, and the rotate counterclockwise of earthed switch axle 11 can be driven with grounding shaft driving crank 12 by being grounded drive link 10,
Earthing is driven to close a floodgate, while driving the isolation ground connection division direction board 13 on fairlead 3 to rotate；When contact of earth in place, every
Isolation separating brake contact of earth position is indicated from ground connection division direction board 13；
Size dome platform on operation key 1 closes position with having rotated to isolation tap（Following big gap position）, every
It is located in the radial direction elongated slot in the L-shaped groove of two-stage propulsion clutch 4 from coupled axle-pin 5, the spindle drive of isolation knife is in and departs from shape
State, the cutting that the groove on two-stage propulsion clutch 4 is protruded above with ground connection clutch-linkage crank 6 is fastened and can not flicked, and extracts behaviour
Make key.
Now two-stage propulsion clutch 4 is connected with ground connection clutch-linkage crank 6, therefore can be switched with operational grounding, meanwhile,
Isolation coupled axle-pin 5 is located in the radial direction elongated slot in the L-shaped groove of two-stage propulsion clutch 4, two-stage propulsion clutch 4 and disconnecting switch
Axle 7 is separated, and when two-stage propulsion clutch 4 rotates, isolation switch shaft 7 dallies, it is impossible to disconnecting switch operation, prevents earthed switch
Mistiming in the close position closes disconnecting switch；
Close position in alignment isolation tap ground（Following big breach indicating positions）, the promotion operation protection of insertion operation key 1
Lock tube 14 is retracted, rotate counterclockwise operation key 1, drives the two-stage propulsion rotate counterclockwise of clutch 4, drives ground connection clutch-linkage
The rotate counterclockwise of crank 6, the dextrorotation of earthed switch axle 11 can be driven by being grounded drive link 10 with grounding shaft driving crank 12
Turn, drive earthing separating brake；
Size dome platform on operation key 1 has rotated to isolating tap point position（Big gap position above）, this
When isolation coupled axle-pin 5 be located at two-stage propulsion clutch 4 L-shaped groove the short groove in axial direction in, if client needs disconnecting switch operation,
Part operation key 1 is exited, the small dome platform on operation key 1 is stayed in the inner side of switching mechanism panel 2, big dome platform is return
The outside of switching mechanism panel 2, two-stage advances clutch 4 under the acting in opposition of small pressure spring 15 to the direction bullet of switching mechanism panel 2
Go out, the cutting that the groove on two-stage propulsion clutch 4 is protruded above with ground connection clutch-linkage crank 6 is separated, it is impossible to which operational grounding is opened
Close, isolation coupled axle-pin 5 is returned in the short groove in axial direction of the L-shaped groove of two-stage propulsion clutch 4, and two-stage advances clutch 4 and keeps apart
Axle 7 is closed to connect, now can be with disconnecting switch operation；
Rotate counterclockwise operates key 1, drives the two-stage propulsion rotate counterclockwise of clutch 4, drives the inverse time of isolation switch shaft 7
Pin rotates, and drives isolation knife to close a floodgate；When isolation axle limiting plate 9 encounters isolation axle gag lever post 8, isolate in-place closing；Operation key
Size dome platform with having rotated to isolation splice grafting point position on spoon 1（Small gap position）, then extract operation key 1.
In addition：It should be noted that above-mentioned specific embodiment is only a prioritization scheme of this patent, the skill of this area
Any change or improvement that art personnel are done according to above-mentioned design, within the protection domain of this patent.
