Description
Technical field
The present invention relates to breaker technical fields, and the special of breaker spring operating mechanism is configured at more particularly to a kind of
Five is anti-chain.
Background technology
In the actual motion of power switchgear, machine driving locking part often breaks down, wherein breaker operator
Five between motivation structure and disconnecting switch prevent chain frequent failure, and most of five prevent that chain flexibility is larger, are susceptible to event
Barrier is based on disadvantages described above and deficiency, it is necessary to be improved existing technology..
Invention content
It being configured at the special five anti-of breaker spring operating mechanism the invention mainly solves the technical problem of providing a kind of
It is chain, it is compact-sized, using cam structure can simple and stable delivery stroke, ensure interlocking reliability, disk cam uses
Thicker plate material ensures a whole set of chain rigidity, achievees the effect that steady in a long-term.
In order to solve the above technical problems, one aspect of the present invention is：One kind is provided and is configured at breaker bullet
Special the five of spring operating mechanism are anti-chain, this kind is configured at special the five of breaker spring operating mechanism and prevents that chain includes breaker
Mechanism, first connecting rod, second connecting rod, interrupter, guiding trestle, cam, push plate and cam top plate, the breaker mechanism
Output toggle arm is hinged by one end of pivot pin and first connecting rod, and the other end and second connecting rod of first connecting rod are locked by bolt,
Isolation operating mechanism is provided with below breaker mechanism, guiding trestle is installed on the front plate of interrupter, on guiding trestle
It is provided with pilot hole and is horizontally disposed with, second connecting rod passes through guiding trestle, and cam is equipped in the operating shaft of interrupter, open circuit
Push plate has been bolted in the junction panel of device mechanism lower part, and push plate lower part is fixed by bolt and cam top plate, cam top plate
With cam engagement.
Preferably, the second connecting rod is in " L " shape, and the vertical portion of second connecting rod is at guiding trestle, second connecting rod
When pressed status, the horizontal part of second connecting rod blocks the operating shaft of interrupter.
Preferably, the cam is disc cam, and cam uses heavy-gauge sheeting, thicker plate material to be enough to ensure that whole chain rigid
Property, effect steady in a long-term is reached, cam is installed on by elastic cylindrical pin in the operating shaft of interrupter.
Compared with prior art, the beneficial effects of the invention are as follows：It is compact-sized, using cam structure can simple and stable it is defeated
Go out stroke, ensures that interlocking reliability, disk cam use thicker plate material, it is sufficient to ensure a whole set of chain rigidity, reach long-term
Stable effect, such linkage mode use guide-bar mechanism, and during divide-shut brake, latch lever does not have bright breaker mechanism
Aobvious resistance consumes the divide-shut brake output work of breaker mechanism, makes breaker smoothly reliable divide-shut brake.

Fig. 2 closes a floodgate for interrupter of the present invention, breaker mechanism combined floodgate structural schematic diagram.
Fig. 3 is interrupter separating brake of the present invention, breaker mechanism separating brake structural schematic diagram.
Specific implementation mode
Present pre-ferred embodiments are described in detail below in conjunction with the accompanying drawings, so as to can be more easy to feature the advantages of invention
In being readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
It please refers to Fig.1 to Fig.3, the embodiment of the present invention includes：
A kind of to be configured at the special five anti-chain of breaker spring operating mechanism, this kind is configured at breaker spring actuating machine
Special the five of structure are anti-chain including breaker mechanism 1, first connecting rod 2, second connecting rod 3, interrupter 4, guiding trestle 5, cam
6, the output toggle arm 11 of push plate 7 and cam top plate 8, the breaker mechanism 1 is hinged by one end of pivot pin and first connecting rod 2,
The other end and second connecting rod 3 of first connecting rod 2 are locked by bolt, and 1 lower section of breaker mechanism is provided with isolation operating mechanism 4,
Guiding trestle 5 is installed on the front plate 41 of interrupter 4, pilot hole and horizontally disposed, the second company are provided on guiding trestle 5
Bar 3 passes through guiding trestle 5, and cam 6 is equipped in the operating shaft 42 of interrupter 4, and the junction panel 12 of 1 lower part of breaker mechanism is logical
It crosses and has been bolted push plate 7,7 lower part of push plate is fixed by bolt and cam top plate 8, and cam top plate 8 coordinates with cam 6.
The second connecting rod 3 is in " L " shape, and the vertical portion of second connecting rod 3 passes through guiding trestle 5, and second connecting rod 3, which is in, to be pushed
When state, the horizontal part of second connecting rod 3 blocks the operating shaft 42 of interrupter 4.
The cam 6 is disc cam, and cam 6 uses heavy-gauge sheeting, thicker plate material to be enough to ensure that whole chain rigidity, make it
Achieve the effect that steady in a long-term, cam 6 is installed on by elastic cylindrical pin in the operating shaft 42 of interrupter 4.
When a kind of special five anti-chain work being configured at breaker spring operating mechanism of the invention, interrupter 4 is beaten
When "on" position, cam 6 is in stop segment, and cam top plate 8 is in and does not jack up state, and breaker mechanism 1 close a floodgate dynamic at this time
To make, output toggle arm 11, which rotates down, pushes 3 downward actuation of second connecting rod, second connecting rod 3 to block the operating shaft 42 of interrupter 4,
Under 1 "on" position of breaker mechanism, interrupter 4 can not carry out sub-switching operation, only by 1 separating brake of breaker mechanism, isolation
Mechanism 4 can just carry out sub-switching operation, and when interrupter 4 carries out sub-switching operation, operating shaft 42 carries out rise with moving cam 6 and moves
Make, cam 6 jacks up cam top plate 8, and cam top plate 8 boosts junction panel 12, and breaker mechanism 1 can not carry out combined floodgate behaviour at this time
Make.
The present invention is a kind of to be configured at the special five anti-chain of breaker spring operating mechanism, compact-sized, using cam knot
Structure can simple and stable delivery stroke, ensure interlocking reliability, disk cam uses thicker plate material, ensures a whole set of chain rigid
Property, achieve the effect that steady in a long-term.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
