Abstract
The invention belongs to high-tension switch gear, it is related to a kind of breaker and isolator operation interlocking mechanism.The mechanism includes isolator operation axle, and two draw-in grooves are distributed with the external cylindrical surface of isolator operation axle；Isolator operation axle outside is provided with a linkage connecting lever, and linkage connecting lever rear end is fixed fulcrum shaft；Linkage connecting lever middle part connects the divide-shut brake action part of breaker by the pull bar being hinged therewith, and the divide-shut brake action of breaker can drive linkage connecting lever around the upper and lower swing of fulcrum shaft；Linkage connecting lever front end has the hook gone out to isolator operation aixs cylinder, and when disconnecting switch separating brake and closing position, the hook is respectively aligned to two draw-in grooves and can snap in draw-in groove in breaker closing state isolator operation axle position.Simple structure of the present invention, manufacture and easy for installation, locking reliability is high.
Description
Technical field
The invention belongs to high-tension switch gear, it is related to a kind of breaker and isolator operation interlocking mechanism.
Background technology
In high-tension switch cabinet, during breaker treatment "on" position, operational procedure does not allow the disconnecting switch to carry out separating brake or conjunction
Lock is operated, it is therefore desirable to interlocked.Existing mechanical interlock mechanism has complex structure, mounting and adjusting inconvenience, action can
By defects such as property differences；And using electrical equipment locking, then reliability of operation is not easy to ensure.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of simple structure, manufacture and easy for installation, Reliability of Microprocessor
Breaker high and isolator operation interlocking mechanism.
Breaker of the invention can drive disconnecting switch divide-shut brake to move with isolator operation interlocking mechanism including one
The isolator operation axle of work, is distributed with two draw-in grooves on the external cylindrical surface of isolator operation axle；Isolator operation axle
Outside is provided with a linkage connecting lever, and linkage connecting lever rear end is fixed fulcrum shaft；Linkage connecting lever middle part passes through what is be hinged therewith
Pull bar connects the divide-shut brake action part of breaker, the divide-shut brake of breaker is acted can drive linkage connecting lever on fulcrum shaft,
Lower swing；Linkage connecting lever front end has the hook gone out to isolator operation aixs cylinder, and isolator operation axle position is in disconnecting switch
When separating brake and closing position, the hook is respectively aligned to two draw-in grooves and can snap in draw-in groove in breaker closing state.
The linkage connecting lever is located at isolator operation axle top.
Simple structure of the present invention, manufacture and easy for installation, it is by way of forced blocking to breaker and disconnecting switch
Operation limited, locking reliability is high, it is ensured that effective realization of safety code.
Brief description of the drawings
Fig. 1 is structural representation of the embodiment of the present invention in disconnecting switch closing position；
Fig. 2 is structural representation of the embodiment of the present invention in disconnecting switch open position.
Specific embodiment
As illustrated, the breaker can drive disconnecting switch divide-shut brake with isolator operation interlocking mechanism including one
The isolator operation axle 1 of action, is distributed with two draw-in grooves 2 on the external cylindrical surface of isolator operation axle；Disconnecting switch is grasped
Make the top of axle 1 and be provided with a linkage connecting lever 3, linkage connecting lever rear end is fixed fulcrum shaft 4；Linkage connecting lever 3 middle part by with
The pull bar 5 that is hinged connect the divide-shut brake action part of breaker, the divide-shut brake action of breaker can drive linkage connecting lever 3 around
The upper and lower swing of fulcrum shaft 4；Linkage connecting lever 3 front end has the hook 6 gone out to isolator operation aixs cylinder, isolator operation axle 1
During positioned at disconnecting switch separating brake and closing position, the hook 6 is respectively aligned to two draw-in grooves and can be in breaker closing state
Snap in draw-in groove.
In the course of work of the present invention：
When disconnecting switch is located at closing position, if breaker closing, the hook 6 of the connecting lever that links is moved down and is entrapped in first
In individual draw-in groove, as shown in figure 1, now isolator operation axle cannot be rotated, thus sub-switching operation is unable to；
When disconnecting switch is located at closing position, if breaker closing, the hook 6 of the connecting lever that links is moved down and is entrapped in the
In two draw-in grooves, as shown in Fig. 2 now isolator operation axle cannot also be rotated, thus closing operation is unable to.
