Abstract
The mechanical interlocking structure of a kind of breaker of the utility model and three position mechanism, is related to breaker attachment structure field, including vacuum circuit breaker, three position mechanism, interlock and closing piece；The switching-on mechanism of vacuum circuit breaker is connected by interlock with three position mechanism；Coordinated signals are carried out by closing piece between three position mechanism and interlock；Interlock includes guide pin bushing and connecting rod；Guide pin bushing is fixed in vacuum circuit breaker；Connecting rod empty boasting is in guide pin bushing；One end of connecting rod is connected to closing piece after three position mechanism；Optoelectronic induction head is additionally provided with vacuum short-circuiting device；Optoelectronic induction head is located at the end of interlock；Optoelectronic induction head perceives the telescopic location of connecting rod.Said structure can realize that breaker closing can not close a floodgate breaker and operation tri-station isolating switch again simultaneously, and the isolation divide-shut brake breaker not in place that can not close a floodgate not in place can not carry out breaker operator and isolated operation with carrying out ground connection operation, ground connection operation.
Description
Technical field
The utility model is related to breaker attachment structure field, the machine of more particularly to a kind of breaker and three position mechanism
Tool interlock.
Background technology
, it is necessary to which breaker does not allow operation when being in "on" position for the switch cubicle equipped with tri-station isolating switch
Tri-station isolating switch, breaker allows to operate tri-station isolating switch when being in gate-dividing state；Tri-station isolating switch is operated
Breaker could be closed after in place, operation is not in place can not to close breaker.In addition, open circuit of closing a floodgate can not be carried out during breaker closing again
Device is operated, and ground connection operation can not carry out isolated operation when not in place, and ground connection operation can not be carried out when isolated operation is not in place.It is existing
There is the manually operated without being automatically locked and taking off mouth function automatically of many isolation in technology and ground connection, it is manually operated not tie
Beam, Manual operation handle can also be extracted, if imperfect interlock, easily carry out maloperation.Utility model patent《One
Plant the mechanical interlock mechanism of breaker and tri-station isolating switch》Pass through a company between breaker and tri-station isolating switch
Bar realizes the mutual restriction between disconnecting switch and breaker, and the interlocking to tri-station isolating switch is defeated by limiting three stations
The mode that shaft is rotated, is passive interlocking, less reliable.
Utility model content
The utility model is mainly solving the technical problems that provide the mechanical interlocking knot of a kind of breaker and three position mechanism
Structure, solves the problem of breaker is difficult to monitoring with the asynchronous and linkage structure of three position mechanism linkage.
In order to solve the above technical problems, the technical scheme that the utility model is used is to provide a kind of breaker and three works
The mechanical interlocking structure of position mechanism, including vacuum circuit breaker, three position mechanism, interlock and closing piece；The vacuum circuit breaker
Switching-on mechanism be connected by interlock with the three position mechanism；Pass through institute between the three position mechanism and interlock
State closing piece and carry out coordinated signals；The interlock includes guide pin bushing and connecting rod；The guide pin bushing is fixed in the vacuum circuit breaker；
The connecting rod empty boasting is in guide pin bushing；One end of the connecting rod is connected to the closing piece after the three position mechanism；It is described true
Optoelectronic induction head is additionally provided with empty short-circuiting device；The optoelectronic induction head is located at the end of interlock；The optoelectronic induction head sense
Know the telescopic location of connecting rod.
Preferably, when the vacuum circuit breaker is in "on" position, interlock drives to the closing piece, the closing piece
Pin the valve of the three position mechanism.
Preferably, it is additionally provided with location identification unit on the three position mechanism.
The beneficial effects of the utility model are：The mechanical interlocking structure of a kind of breaker and three position mechanism is provided, can
Realizing breaker closing simultaneously can not close a floodgate breaker and operation tri-station isolating switch again, and divide-shut brake is not in place to close for isolation
Lock breaker is with carrying out ground connection operation, and ground connection operation is not in place can not to carry out breaker operator and isolated operation.
Brief description of the drawings
Fig. 1 is the structural representation of the mechanical interlocking structure of a kind of breaker of the utility model and three position mechanism；
The mark of each part is as follows in accompanying drawing：1st, vacuum circuit breaker；2nd, three position mechanism；3rd, interlock；4th, closing piece；5、
Optoelectronic induction head.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite
Define.
Accompanying drawing 1 is referred to, the utility model embodiment includes：
A kind of mechanical interlocking structure of breaker and three position mechanism, including vacuum circuit breaker 1, three position mechanism 2, interlocking
Device 3 and closing piece 4；Include valve and location identification unit on three position mechanism 2.The switching-on mechanism of vacuum circuit breaker 1 passes through connection
Locking device 3 is connected with three position mechanism 2；Coordinated signals are carried out by closing piece 4 between three position mechanism 2 and interlock 3；Interlocking
Device 3 includes guide pin bushing and connecting rod；Guide pin bushing is fixed in vacuum circuit breaker 1；Connecting rod empty boasting is in guide pin bushing；One end of connecting rod passes through three
Closing piece is connected to after station mechanism 2；Optoelectronic induction first 5 is additionally provided with vacuum short-circuiting device 1；Optoelectronic induction first 5 is located at interlock 3
End；The telescopic location of connecting rod is known in optoelectronic induction head sense 5, when interlock 3 produced because of mechanical problem it is stuck, its certainly will
It can not return to initial position, and optoelectronic induction first 5 can be to detect the position of connecting rod in time；Also or connecting rod is in permanent worker
It is deformed or weares and teares in work, optoelectronic induction head can also detect the wear extent of connecting rod in time, so as to is repaired in time.Very
When empty breaker is in "on" position, interlock drives to closing piece, and closing piece pins the valve of three position mechanism；When three station machines
During the valve open mode of structure, by interlock so that breaker can not operate combined floodgate.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
The technical field of pass, is similarly included in scope of patent protection of the present utility model.
