It sets isolation fracture 111 and linkage is set in insulation booth.All components of vacuum extinction chamber component are all integrated to be enclosed in
In one insulation booth, top adds insulation box cover 12, and insulation is reliable, can be no longer filled with pollution when loaded in box of the circuit breaker body
SF6 gas carries out insulating strength, more environmentally-friendly.
The specific structure of vacuum extinction chamber component 1 is as shown in Figure 3,4:
Electric conduction rod component 18 is respectively arranged on the left and right ends of insulation booth 16, and vacuum interrupter 17 is placed in inside insulation booth
Right side is equipped with arc-chutes static contact 171 and arc-chutes moving contact 173 in vacuum extinction room.The electric conduction rod component 18 of right end with go out
The connection of arc chamber static contact.The electric conduction rod component of left end is connect with static contact, and type of attachment can be the shapes such as threaded connection, clamping
Formula.Guiding trestle 19 is set to the left side of vacuum interrupter, and guiding trestle bottom is equipped with mounting hole, and mounting hole and insulation booth screw thread connect
Fixation is connect, the right side of guiding trestle is equipped with supported hole, and supported hole is sheathed on the left end of vacuum interrupter, goes out for fixing vacuum
Arc chamber, arc-chutes moving contact 173 pass through supported hole be fixedly connected with the right end that tool apron 15 be isolated, type of attachment for threaded connection or
Clamping.
Be isolated tool apron 15 left end be isolated blade 11 by pivot pin component 14 rotation connection, pivot pin component includes pivot pin
143, rolling bearing 141, blade pressure spring 142 and screw 144 are led specifically, isolation tool apron and isolation knife on piece are equipped with connecting hole
It is equipped with horizontal concrete chute to bracket, pivot pin passes through connecting hole and is slidably connected with horizontal concrete chute, and pivot pin is set with horizontal concrete chute junction
There is rolling bearing, the setting of rolling bearing guarantees that pivot pin can be free to slide in horizontal concrete chute, and blade compression spring sleeve is set to pivot pin
On, and be located between isolation blade and guiding trestle, blade pressure spring applies the work to isolation tool apron direction to isolation blade
Firmly, guarantee that reliable contacts blade is isolated with tool apron is isolated, screw are installed on the both ends of the surface of pivot pin.
Guiding trestle 19 is equipped with guide groove 191, and isolation blade is slidably connected with guide groove by pivot pin component 14, pivot pin
Component includes pivot pin 143, rolling bearing 141, blade pressure spring 142 and screw 144, specifically, isolation knife on piece is equipped with through-hole, axis
Across through-hole, pivot pin is slidably connected pin with guide groove, and pivot pin and guide groove junction are equipped with rolling bearing, the setting of rolling bearing
Guaranteeing that pivot pin can be free to slide in guide groove, screw is installed on the both ends of the surface of pivot pin, and blade compression spring sleeve is set on pivot pin, and
It is located between isolation blade and guiding trestle, blade pressure spring applies the active force to static contact direction to isolation blade, protects
The reliable contacts of card isolation blade and static contact.
Guide groove 191 is sequentially connected by two sections of arc grooves and is formed, and the center of circle and the arc extinguishing moving contact 173 of the arc groove of top divide
Lock in place when pivot pin in horizontal concrete chute the center of circle it is identical, the arc groove center of circle that the center of circle of the arc groove of lower section is located above
Upper left side.The shape restrictive condition of the arc groove of lower section are as follows: the vertical displacement that arc groove of the isolation blade 11 in lower section slides
Vertical displacement when less than isolation blade from blade "on" position to just gate-dividing state, arc groove of the isolation blade in lower section are sliding
Dynamic horizontal displacement be equal to moving contact 173 from contact "on" position to contact separating brake in place when horizontal displacement, this restrictive condition
When still partially engaged in order to which blade 11 and static contact 110 are isolated when guaranteeing 17 disjunction of vacuum interrupter in place.
"on" position is as shown in figure 5, isolation fracture 111 is closed under this state, and vacuum interrupter fracture 172 is closed, separating brake
When, isolation blade 11 is slided along the arc groove of lower section from the bottom to top, and isolation blade drives isolation tool apron 15 and arc-chutes moving contact
173 are moved to the left, and vacuum interrupter starts separating brake；As shown in fig. 6, when isolation blade slides into arc groove and the top of lower section
When arc groove joint, arc-chutes moving contact is in separating brake state in place, but there are no separate static contact with blade is isolated；Such as figure
Shown in 7, the subsequent arc groove along top of isolation blade is slided, in place due to the arc groove center of circle of top and arc extinguishing moving contact separating brake
When pivot pin in horizontal concrete chute the center of circle it is identical, i.e., the pivot pin in horizontal concrete chute is in the center of circle of top arc groove at this time
Place, therefore arc groove of the blade along top is isolated and slides, it not will drive isolation knife seat and arc-chutes moving contact move left and right, it is built-in
Isolation fracture continues to separate；As shown in figure 8, built-in isolation fracture 111 also separates in place, isolation fracture separation distance is greater than
35mm, isolation fracture and arc-chutes fracture all separating brakes are in place.When separating brake, first divide arc-chutes fracture, after divide isolation fracture, guarantee every
Detachment mouth will not charge disjunction.Making process and separating brake process first close isolation fracture on the contrary, when closing a floodgate, rear to close arc-chutes fracture,
Guarantee that isolation fracture will not charge combined floodgate, this setting guarantees that built-in isolation fracture will not be charged and be failed when divide-shut brake.
On the other hand the utility model provides a kind of vacuum circuit breaker, including operating mechanism, complete by operation operating mechanism
