Abstract
The utility model relates to a single air chamber self energy arc-extinguishing breaker arc extinguish chamber of the electric power industry. The single air chamber self energy arc-extinguishing breaker arc extinguish chamber consists of an upper support base, a lower support base, a stationary arc contact, a stationary main contact, a spout, an air chamber, a movable main contact, a movable arc contact and a cylinder terminal, etc. The upper support base is respectively equipped with the stationary arc contact and the stationary main contact in a fixed way. The upper end of an insulating table is connected with the upper support base in a seal way, and the lower end is connected with the upper end of a jacket. The lower support base is equipped with a piston in a fixed way. The end of a piston rod is provided with the cylinder terminal. The cylinder terminal is respectively provided with the spout, the movable main contact and the movable arc contact. The cylinder terminal is provided with an inclined hole which is communicated with a cylinder, so when the piston rod descends, the air in the cylinder forms a top blowing form in the air chamber to form very good arc extinguishing effect. An arc extinguish chamber is designed as a single air chamber, so the single air chamber self energy arc-extinguishing breaker arc extinguish chamber ensures the simple structure and reduces the size.
Description
Technical field
The utility model relates to the circuit breaker of power industry, the arc control device that use on specifically a kind of circuit breaker.
Background technology
Relevant by retrieval patent documentation does not retrieve the arc control device on the circuit breaker identical with the utility model structure at present as yet.General two air chambers or the air pressing type arc quenching principle of adopting of the arc control device of existing circuit breaker comes contact arc is carried out the extinguishing arc processing, because two air chamber arc control device are relatively complicated, add to arc control device part requirement height, thereby product cost is improved greatly, and the life cycle of product is shortened dramatically, and because its structural reason is difficult to satisfy the requirement of its structure especially to the miniaturization combined electrical apparatus, so be necessary existing arc-extinguishing chamber of circuit breaker is improved to satisfy its actual demand.
Summary of the invention
The purpose of this utility model is will provide a kind of can realize automatic arc extinguishing function, and the arc-extinguishing chamber of circuit breaker of single air chamber self-energy quenching arc simple in structure.
Technical characterictic of the present utility model is: considering to be designed to be supported by top on arc extinguishing automatically, the basis simple in structure the arc-extinguishing chamber of circuit breaker of single air chamber self-energy quenching arc that seat, quiet arc contact, quiet main contact, spout, air chamber, insulation pad, moving main contact, moving arcing contact, piston, cylinder, lower support seat, piston rod, overcoat, cylinder termination, conductive plate are formed, be fixed with quiet arc contact, quiet main contact respectively in top support; The insulation pad upper end supports seat to be tightly connected mutually with top, and the lower end is connected with the upper end of overcoat; The lower end of described overcoat is connected with the lower support seat; On the lower support seat, be fixed with piston; The inner chamber of piston is provided with piston rod, is provided with the cylinder termination on the end of piston rod, matches with cylinder in the cylinder termination; On the cylinder termination, be respectively equipped with spout, moving main contact, moving arcing contact; Air chamber is arranged on the moving arcing contact, and described piston is packed on the lower support seat, and described conductive plate is packed on the lower support seat and with the lower support seat and contacts.
Described spout is provided with the V-arrangement opening on its end, be provided with several groove within it in the hole.
Described cylinder termination is provided with the inclined hole that is used to ventilate.
When needs close circuit breaker, up at the drive lower piston rod of operating mechanism, and drive cylinder termination, cylinder and moving arcing contact, air chamber, spout moves upward; Contact to closing position with quiet arc contact, quiet main contact up to moving main contact, moving arcing contact.When the needs separating brake, under the drive of operating mechanism, descending and the drive cylinder termination of piston rod, cylinder, moving arcing contact, air chamber, spout moves downward, at moving main contact, moving arcing contact and quiet main contact, when the quiet arc contact separates, under the high-voltage great-current effect, between contact, produce electric arc, and make the gas in the air chamber add thermal expansion rapidly, add to piston rod and move down back drive cylinder, the cylinder termination moves down, distance between cylinder termination and the piston is diminished, and the gas in the cylinder is up along the inclined hole A of cylinder termination, and air-flow outwards sprays from the spout air gap, thereby blow out the electric arc in the spout air gap, contact continues then to arrive the separating brake position downwards, reaches the purpose of breaker open operation.
The utility model has the advantages that: because the cylinder termination is provided with inclined hole, and connects with cylinder, thereby when piston rod is descending, make gas in the cylinder in air chamber, form the form of top blast, form good arc quenching effect; Because arc control device are designed to single air chamber, thereby make simple in structurely, reduced product cost, reduced volume; Because rational in infrastructure, dependable performance is so there is very big practical and popularizing value.
