Abstract
The utility model discloses an arc extinguisher of a sulfur hexafluoride breaker, which comprises a cylinder. An air-compressing piston which is matched with the cylinder in a sliding manner is mounted in the cylinder, a mounting base is arranged on one end of the cylinder, and is provided with air holes, an air-jetting base body is fixed on the mounting base, a cavity which contains a movable contact of the breaker is formed on the air-jetting base body, and a jet nozzle which is communicated with the cavity is arranged on one end of the air-jetting base body. The utility model has the advantage of good arc-extinguishing effect.
Description
Technical field
The utility model relates to a kind of arc-control device, is specifically related to the arc-control device of sulfur hexafluoride breaker.
Background technology
In the course of action of switch, the voltage between the contact causes the air dielectric discharge, forms electric arc.Therefore in various device for switching such as circuit breaker, contactor, arc control device all are set usually come extinguish arcs, to guarantee the electric equipment security of operation.
Arc control device generally comprise the arc extinguishing grid pieces of the parallel installation of multi-disc, are used for cutting off and extinguish arcs.In order to improve arc quenching effect, the top of the arc control device that have also is provided with run-on tab, the run-on tab of existing arc control device is metallic plates, it be installed in arc control device directly over, comprise a parallel-segment that parallels with arc extinguishing grid pieces and an ascent stage obliquely, the ascent stage is positioned at the front end of run-on tab, the junction of parallel-segment and ascent stage forms arc leading angle, in this structure, arc leading angle is an obtuse angle, and its striking effect is not very desirable.
Summary of the invention
At above-mentioned technical problem, the utility model provides the arc-control device of the good sulfur hexafluoride breaker of a kind of arc quenching effect.
The technical scheme that realizes above-mentioned purpose is as follows:
The arc-control device of sulfur hexafluoride breaker, comprise a cylinder body, be provided with the displacer that is slidingly matched with cylinder body in this cylinder body, one end of cylinder body is provided with mount pad, mount pad is provided with air vent hole, fix a jet pedestal on the mount pad, form a cavity that holds moving contact of breaker on the jet pedestal, an end of jet pedestal is provided with the nozzle that is communicated with described cavity.
The other end of jet pedestal is provided with guide post, is provided with through hole on mount pad, is provided with pilot hole on displacer, and described guide post passes through hole and pilot hole successively.
Adopted such scheme, when circuit breaker trip, moving contact separates with fixed contact, produces electric arc.At this moment, cylinder body moves downward under the effect of power set, cause cylinder body and displacer relative motion, cylinder body compresses sulfur hexafluoride gas in motion process, make it produce the air-flow that pressure is pressed very much, sulfur hexafluoride gas is gone out arc blow-out by air vent hole, cavity, nozzle ejection, thereby electric arc is extinguished rapidly.The utlity model has the good advantage of arc quenching effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
In the accompanying drawing, 1 is cylinder body, and 2 is displacer, and 3 is mount pad, and 4 is air vent hole, and 5 is jet pedestal, and 6 is cavity, and 7 is nozzle, and 8 is guide post.
Embodiment
With reference to Fig. 1, the arc-control device of sulfur hexafluoride breaker comprises a cylinder body 1, and the sulfur hexafluoride gas that is used for arc extinguishing is housed in cylinder body.Be provided with the displacer 2 that is slidingly matched with cylinder body in the cylinder body 1, displacer 2 relative cylinder bodies are fixed, one end of cylinder body is provided with mount pad 3, mount pad 3 is provided with air vent hole 4, fix a jet pedestal 5 on the mount pad 3, form a cavity 6 that holds moving contact of breaker on the jet pedestal 5, an end of jet pedestal is provided with the nozzle 7 that is communicated with described cavity.The other end of jet pedestal is provided with guide post 8, is provided with through hole on mount pad, is provided with pilot hole on displacer, and described guide post passes through hole and pilot hole successively.By the guide effect of guide post, make mount pad 3 more steady in the process that moves.
The course of work of the present utility model is: when circuit breaker trip, moving contact separates with fixed contact, produces electric arc.At this moment, cylinder body 1 moves downward under the effect of power set, causes cylinder body 1 and displacer 5 relative motions, and cylinder body 1 compresses sulfur hexafluoride gas in motion process, sulfur hexafluoride gas ejects arc blow-out by air vent hole 4, cavity 6, nozzle 7, thereby electric arc is extinguished rapidly.
