Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail, described in be explanation of the invention and
It not to limit.
As it is shown in figure 1, the mechanical interlock mechanism of a kind of chopper of the present invention and tri-station isolating switch includes: chopper
Interlock 1, interlock plate 2, pin 3, valve 4 and position identification device 5.
Described circuit breaker interlocking device 1 includes: attach the connecting lever 11 on breaker main shaft, connecting rod 12, chopper clamp
13 and combined floodgate semiaxis 14；Chopper clamp 13 rotary setting is on breaker mechanism, and connecting rod 12 one end is hinged with connecting lever 11, another
Holding and be slidably connected with chopper clamp 13 by the oval hole arranged, chopper clamp 13 one end is circular arc, on combined floodgate semiaxis 14
There is the plane tangent with the circular arc of chopper clamp 13.
Described position identification device 5 includes: cam instruction dish 51, roller 52, roller connecting lever 53 and spring 54；Cam indicates
Dish 51 is fixed on tri-station isolating switch mechanism main shaft, and on cam instruction dish, 51 have 3 projections or groove, respectively correspondence isolation
Conjunction, two points, three positions of ground connection；Illustrating as a example by 3 grooves in this preferred embodiment, roller connecting lever 53 rotary setting is in three
On station mechanism, roller connecting lever 53 is rotationally connected with roller 52, and roller connecting lever 53 makes roller 52 be close under the effect of spring 54
The profile of cam instruction dish 51.
Described interlock plate 2 one end connects the other end of chopper clamp 13 on circuit breaker interlocking device 1, and the other end connects position
Put roller connecting lever 53 other end identified on device 5, interlock plate 2 is fixedly installed pin 3.
Described valve 4 is provided with three breach, when valve 4 blocks isolated operation axle 6 and ground connection operation axle 7 simultaneously, lives
Second breach 42 of door is corresponding with pin 3；When valve 4 exposes isolated operation axle 6, valve the 3rd breach 43 is corresponding with pin 3；
When valve 4 exposes ground connection operation axle 7, valve the first breach 41 is corresponding with pin 3.
Under original state, breaker closing, tri-station isolating switch is in closing position, and valve 4 had both kept off isolated operation axle 6
Gear ground connection operation axle 7 again, as shown in Figure 1.Now, connecting lever 11 makes the circular arc of chopper clamp 13 block conjunction by connecting rod 12 effect
The plane of lock semiaxis 14, makes combined floodgate semiaxis 14 not rotate, it is impossible to chopper is carried out closing operation；Linkage interlock plate 2 simultaneously
On pin 3 block valve the second breach 42, stop that valve 4 rotates, now can not carry out isolated operation.
Such as Fig. 2, when chopper is in time closing a floodgate to separating brake, and crank of circuit breaker 11 rotates counterclockwise, the work in connecting rod 12 oval hole
Rotate clockwise with allowing chopper clamp 13.Roller connecting lever 53 rotates counterclockwise under the effect of spring 54, above pushes away interlock plate 2
Making chopper clamp 13 rotate clockwise, the circular arc of chopper clamp 13 departs from the plane of combined floodgate semiaxis 14, chopper clamp
13 no longer block breaker closing semiaxis 14, and pin 3 no longer blocks valve the second breach 42, it is allowed to valve 4 rotates counterclockwise,
Now, can close a floodgate chopper, again can disconnecting switch operation.
When breaker open operation, valve 4 can be rotated and operate axle 6 with operation isolation.As it is shown on figure 3, when isolation divide-shut brake
Time not in place, roller 52 is no longer on the breach of cam instruction dish 51, and then makes roller connecting lever 53 rotate clockwise, drop-down
Jam plate 2 and pin 3, drive the chopper clamp 13 in circuit breaker interlocking device 1 to rotate counterclockwise, make chopper clamp 13 block
Breaker closing semiaxis 14, chopper can not be closed a floodgate, and pin 3 blocks valve the 3rd breach 43 simultaneously, limits valve 4 clockwise
Rotate and operate axle 7 with operational grounding.Otherwise, as in figure 2 it is shown, when isolating divide-shut brake and putting in place, roller is positioned at cam instruction dish 51
Indentation, there, chopper clamp 13 no longer blocks combined floodgate semiaxis 14, and pin 3 no longer blocks valve the 3rd breach 43 simultaneously, it is allowed to
Valve 4 rotates.Achieve anti-misconnection chopper and operational grounding when isolating divide-shut brake and being not in place and operate the function of axle.
When breaker open operation, valve 4 can be rotated and operate axle 7 with operational grounding.As shown in Figure 4, when ground connection divide-shut brake
Time not in place, position identification device 5 interlock plate 2 that links makes chopper clamp 13 block breaker closing semiaxis 14, it is impossible to carry out
Combined floodgate breaker operator, pin 3 blocks valve the first breach 41 simultaneously, limits valve 4 and rotates counterclockwise with operation isolation operation
Axle 6.Otherwise, as in figure 2 it is shown, when ground connection divide-shut brake puts in place, roller is positioned at the indentation, there of instruction dish 4, and chopper clamp 13 is not
Blocking combined floodgate semiaxis 14 again, pin 3 no longer blocks valve the first breach 41 simultaneously, it is allowed to valve 4 rotates.Achieve and divide ground connection
When closing a floodgate not in place, anti-misconnection chopper and operation isolation operate the function of axle.
It should be noted that for tri-station isolating switch, can not carry out during combined floodgate to be had ground connection operation with
Can not carry out the interlocking of isolated operation during ground connection, this kind of interlocking those skilled in the art use conventional method can solve, at this
Do not repeat.
Above interlock system and interlocking method are intended to illustrate the technological means of the present invention.Those skilled in the art are not changing
On the premise of the technology of the present invention principle, know general knowledge improvement made for the present invention and deformation altogether in conjunction with existing, it should belong to this
Bright protected within the scope of.
