Specific embodiment
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings
When being embodied as, motion mode is: disconnecting switch main shaft 8 rotates, and drives the first most circular rotary wheels 6 to rotate, the
The most circular rotary wheel 7 of a greater part of circular rotary wheel 6 or the second promotes interlock plate 3 to move up and down, and connecting rod 4 one end is with interlock plate 3
Lower movement, the other end slide in the guide groove in fixed plate 5, as shown in Figure 5.
As shown in figure 1, disconnecting switch 1 is in earthing position, interlock plate 3 upper end recess is most with the second of power switch 2
The notch side phase of circular rotary wheel 7 suits, and the second most circular rotary wheels 7 move up and down restriction to interlock plate 3, i.e. interlock plate 3
Rotation to power switch 2 is limited, now as disconnecting switch 1 be grounded, the state of power switch 2 separating brake；As Fig. 2,3
Shown, rotary isolation switch main shaft 8 arrives isolation separating brake, isolation closing position, the first most circular rotary wheels of disconnecting switch 1 successively
Reserve gap between 6 and interlock plate 3, interlock plate 3 moves down, make interlock plate 3 lower end recess most with the first of disconnecting switch 1
The notch side phase of circular rotary wheel 6 suits, and the breach of most circular rotary wheels 7 stays interlock plate 3 upper end recess with the second of power switch 2
Go out certain gap, i.e. the rotation restriction cancellation to power switch 2 for the interlock plate 3；As shown in figure 4, power switch main shaft 9 can turn
Dynamic, make power switch 2 be in closing position, the second most circular rotary wheels 7 of power switch 2 move up and down to interlock plate 3
Limit, that is, interlock plate 3 is limited to the rotation of disconnecting switch 1, now as disconnecting switch is closed a floodgate, power switch closes a floodgate
State.
Summarizing transmission process is: disconnecting switch main shaft 8 rotates to open position by earthing position, is rotated to by open position
Closing position.Now interlock plate 3 moves down, and power switch main shaft 9 side can rotate, operation power switch main shaft 9 make its by point
Lock position rotates to closing position.When power switch main shaft 9 is in closing position, 8, disconnecting switch main shaft is made by interlock plate 3
Put and limited, disconnecting switch 1 cannot action.
Power process is: action power switch main shaft 9 is so as to rotate to open position by closing position first.Now join
The restriction cancellation to disconnecting switch main shaft 8 for the jam plate 3.Then disconnecting switch operation 1 makes it rotate to separating brake by closing position respectively
Position, is rotated again to earthing position.When disconnecting switch main shaft 8 is in open position and earthing position, limited by interlock plate 3
Power switch shaft motion.
