Abstract
The utility model relates to the technical field of a vacuum circuit breaker, particularly to an interlocking mechanism for an inflation-cabinet-type vacuum circuit breaker. The interlocking mechanism is provided with a sketch plate, wherein the sketch plate is fixed in a case through a fixing rod and can rotate along the fixing rod; one end of the sketch plate serves as a connecting interface interlocked with a grounding switch, and the other end of the sketch plate is connected with a connecting rod through a pin; an adjusting screw and a reset spring are mounted on the connecting rod which downwards passes through a guide plate, and the rail end of the connecting rod is close to but not connected with a turning arm installed on a spindle. The interlocking mechanism has the advantages of simple structure, reliable performance, space conservation, compactness and attractive appearance, and meets the requirement of miniaturization and comprehensive function of an inflation cabinet.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker technical field, especially a kind of interlocking device of inflating cabinet type vacuum circuit-breaker.
Background technology
The electric misoperation of high-voltage switch gear causes accidents such as power equipment damage, system blackout even casualties easily.Existing interlocking realize with regard to require machinery and electric aspect require all to realize that the scheme of interlocking has a lot, function also can meet the demands, but some part is more, need be arranged into outside the cabinet, influence its outward appearance, therefore we adopt a kind of novel interlocking, and most of part is integrated into the circuit breaker cabinet inside, make its function and outward appearance that bigger improvement all be arranged.
The utility model content
Be better meeting the market requirement, the utility model provides a kind of interlocking device of inflating cabinet type vacuum circuit-breaker, not only satisfies the miniaturization of inflation cabinet, the requirement of complete function, and also outward appearance is succinctly attractive in appearance.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of interlocking device of inflating cabinet type vacuum circuit-breaker, has sketch plate, sketch plate is fixed in the cabinet by fixed lever, can rotate around fixed lever, sketch plate one end as with the connecting interface of earthed switch interlocking, the other end links to each other with connecting rod by pin, adjustment screw is installed on the connecting rod, and is provided with reseting pressuring spring, connecting rod is passed down through guide plate, terminal approaching with the connecting lever that is installed on the main shaft, do not link to each other.
One bending is arranged on the described connecting lever, when connecting lever rotates, promote the link motion of top, realize interlock.
Described guide plate is fixed on the cabinet inwall.
When breaker closing, main shaft drives the connecting lever rotation, promotes connecting rod and moves upward, and sketch plate interlocking interface moves downward, and this moment, earthed switch can't close a floodgate.
During breaker open operation, connecting lever is rotated away from the connecting rod lower end, when this moment, earthed switch closed a floodgate, pulling sketch plate interlocking interface moves upward, and the sketch plate other end and connecting rod are taken advantage of a situation downwards, and the adjustment screw on the connecting rod props up the switch knob of circuit breaker, circuit breaker can't be closed a floodgate, realize interlock.
The beneficial effects of the utility model are: the gas-filled type vacuum circuit-breaker adopts the utility model interlocking device, and is simple in structure, dependable performance, and conserve space has satisfied the miniaturization of inflation cabinet, the requirement of complete function, and also outward appearance is succinctly attractive in appearance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model A-A schematic diagram.
Among the figure: 1. fixed lever, 2. sketch plate, 3. pin, 4. connecting rod, 5. adjustment screw, 6. switch knob, 7. reseting pressuring spring, 8. guide plate, 9. connecting lever, 10. main shaft, 11. cabinets.
Embodiment
As shown in Figure 1, 2, a kind of interlocking device of inflating cabinet type vacuum circuit-breaker has sketch plate 2, and sketch plate 2 is fixed in the cabinet 11 by fixed lever 1, can rotate around fixed lever 1, sketch plate 2 one ends as with the connecting interface of earthed switch interlocking, the other end links to each other with connecting rod 4 by pin 3, and adjustment screw 5 is installed on the connecting rod 4, and be provided with reseting pressuring spring 7, connecting rod 4 is passed down through guide plate 8, and is terminal approaching with the connecting lever 9 that is installed on the main shaft 10, do not link to each other.
On the described connecting lever 9 bending is arranged, when connecting lever 9 rotates, promote connecting rod 4 motions of top, realize interlock.
Described guide plate 8 is fixed on cabinet 11 inwalls.
When breaker closing, main shaft 10 drives connecting lever 9 rotations, promotes connecting rod 4 and moves upward, and sketch plate 2 interlocking interfaces move downward, and this moment, earthed switch can't close a floodgate.
During breaker open operation, connecting lever 9 is rotated away from connecting rod 4 lower ends, when this moment, earthed switch closed a floodgate, pulling sketch plate 2 interlocking interfaces move upward, sketch plate 2 other ends and connecting rod 4 are taken advantage of a situation downwards, adjustment screw 5 on the connecting rod 4 props up the switch knob 6 of circuit breaker, and circuit breaker can't be closed a floodgate, and realizes interlock.
