Background technique
Inflating cabinet breaker has high breaking and the high ability closed, so in the power system with extensive.Gas-filling cabinet
The ability that breaker requires breaker to have opening velocity fast, safe and reliable during the opening process.Traditional inflating cabinet breaker
Operating principle be that the energy of operating mechanism storage and release tripping spring and is transferred energy to by an insulation spindle
The pull rod of arc-chutes, to realize the switch closing and switch opening of arc-chutes.The method has following deficiency: tripping spring is mounted on behaviour first
Make in mechanism, the energy of release gets to vacuum interrupter by Multi-stage transmission, and energy loss is big, influences the separating brake of breaker
Parameter；Secondly because the components that transmission is passed through are more, the probability of failure is larger.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of circuit breaker for inflating cabinet, reduces
The components that breaker is driven during the opening process reduce the energy loss of tripping spring, improve the machinery of separating brake movement
Parameter and reliability.
The utility model solves technical solution used by its technical problem are as follows:
A kind of circuit breaker for inflating cabinet, including cabinet body, insulation spindle, vacuum interrupter and set on vacuum interrupter upper end
Pull rod, one end of the insulation spindle are connected with operating mechanism, and the other end is connected with connecting lever component, and the insulation spindle is by turning
Arm component drives pull rod to move down to complete the combined floodgate of vacuum interrupter, is connected between the upper end and cabinet body of the pull rod point
Lock spring, the separating brake of the pull rod achievable vacuum interrupter under tripping spring actuation.
As an improvement of the above technical solution, the connecting lever component include main shaft connecting lever, intermediate connecting lever, upper connecting lever and under turn
Arm, one end of the main shaft connecting lever are fixedly connected with the other end of insulation spindle, one end of the hinged intermediate connecting lever of the other end, it is described in
Between the upper end of the other end of connecting lever, the lower end of upper connecting lever and lower connecting lever be articulated with a bit, the upper end of the upper connecting lever is articulated with cabinet
Body, the lower end of the lower connecting lever and pull rod are hinged.
As an improvement of the above technical solution, the tripping spring is tension spring.
As an improvement of the above technical solution, the upper end of the tripping spring is hinged on the upper end of pull rod by connecting rod, even
The middle part of bar is hingedly on the cabinet.
As an improvement of the above technical solution, the upper end of the hinged pull rod in the lower end of the tripping spring, tripping spring it is upper
End is hinged on the cabinet.
The beneficial effects of the utility model have:
For this circuit breaker for inflating cabinet when operating mechanism drives insulation spindle to rotate clockwise, insulation spindle passes through connecting lever group
Part drives pull rod to move downward, so that vacuum interrupter closes a floodgate, carries out combined floodgate holding by operating mechanism later, at this moment tripping spring
Energy is stored since pull rod moves downward；Operating mechanism cancels combined floodgate holding movement, the energy of tripping spring abrupt release at this time
Amount drives pull rod to act upwards, realizes vacuum interrupter separating brake；Compared with existing breaker, this breaker pacifies tripping spring
On the pull rod of vacuum interrupter, reduces the components that breaker is driven during the opening process, reduce tripping spring
Energy loss improves the mechanical parameter and reliability of separating brake movement, reduces probability of failure.
Detailed description of the invention
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail, in which:
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the side view of the utility model embodiment；
Fig. 3 is partial structural diagram in the utility model embodiment.
Specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of circuit breaker for inflating cabinet of the utility model, including cabinet body 8, insulation spindle 1, vacuum
Arc-chutes 2 and pull rod 3 set on 2 upper end of vacuum interrupter, one end of the insulation spindle 1 is connected with operating mechanism 4, the other end
It is connected with connecting lever component 5, tripping spring 6 is connected between the upper end and cabinet body 8 of the pull rod 3, operating mechanism 4 drives insulation master
When axis 1 rotates clockwise, insulation spindle 1 drives pull rod 3 to move down by connecting lever component 5, completes the conjunction of vacuum interrupter 2
Lock carries out combined floodgate holding by operating mechanism 4 later, at this moment the moving downward and store energy due to pull rod 3 of tripping spring 6；
Operating mechanism 4 cancels combined floodgate holding movement, at this time 6 transient burst of energy of tripping spring, and pull rod 3 is driven to act upwards, realizes true
The separating brake of empty arc-chutes 2.
Compared with existing breaker, tripping spring 6 is mounted on the pull rod 3 of vacuum interrupter 2 by this breaker, is reduced
The components that breaker is driven during the opening process reduce the energy loss of tripping spring, improve the machinery of separating brake movement
Parameter and reliability reduce probability of failure.
With further reference to Fig. 3, the specific structure of connecting lever component 5 is that the connecting lever component 5 includes main shaft connecting lever 51, centre
One end of connecting lever 52, upper connecting lever 53 and lower connecting lever 54, the main shaft connecting lever 51 is fixedly connected with the other end of insulation spindle 1, another
One end of the hinged intermediate connecting lever 52 in end, the other end, the lower end of upper connecting lever 53 and the upper end of lower connecting lever 54 of the intermediate connecting lever 52
It is articulated with a bit, the upper end of the upper connecting lever 53 is articulated with cabinet body 8, and the lower end of the lower connecting lever 54 and pull rod 3 are hinged；Insulation master
Axis 1 rotates clockwise, and drives intermediate connecting lever 52 to move to bottom right, the hinge joint of intermediate connecting lever 52, upper connecting lever 53 and lower connecting lever 54
